Nominal Pipe Size ( NPS ) is a North American set of standard sizes for pipes used for high or low pressures and temperatures. "Nominal" refers to pipe in non-specific terms and identifies the diameter of the hole with a non-dimensional number (for example – 2-inch nominal steel pipe" consists of many varieties of steel pipe with the only criterion being a 2.375-inch (60.3 mm) outside diameter). Specific pipe is identified by pipe diameter and another non-dimensional number for wall thickness referred to as the Schedule (Sched. or Sch., for example – "2-inch diameter pipe, Schedule 40"). NPS is often incorrectly called National Pipe Size, due to confusion with the American standard for pipe threads, " national pipe straight ", which also abbreviates as "NPS". The European and international designation equivalent to NPS is DN ( diamètre nominal /nominal diameter/Nennweite), in which sizes are measured in millimetres, see ISO 6708 . The term NB ( nominal bore ) is also frequently used interchangeably with DN.
62-499: In March 1927 the American Standards Association authorized a committee to standardize the dimensions of wrought steel and wrought iron pipe and tubing. At that time only a small selection of wall thicknesses were in use: standard weight (STD), extra-strong (XS), and double extra-strong (XXS), based on the iron pipe size (IPS) system of the day. However these three sizes did not fit all applications. Also, in 1939, it
124-457: A nonbusiness entity , nonprofit institution , or simply a nonprofit , is a legal entity organized and operated for a collective, public or social benefit, as opposed to an entity that operates as a business aiming to generate a profit for its owners. A nonprofit organization is subject to the non-distribution constraint: any revenues that exceed expenses must be committed to the organization's purpose, not taken by private parties. Depending on

Alternatively, it may be a non-membership organization and the board of directors may elect its own successors. The two major types of nonprofit organization are membership and board-only. A membership organization elects the board and has regular meetings and the power to amend the bylaws. A board-only organization typically has
248-554: A fiscally viable entity. Nonprofits have the responsibility of focusing on being professional and financially responsible, replacing self-interest and profit motive with mission motive. Though nonprofits are managed differently from for-profit businesses, they have felt pressure to be more businesslike. To combat private and public business growth in the public service industry, nonprofits have modeled their business management and mission, shifting their reason of existing to establish sustainability and growth. Setting effective missions
310-552: A given schedule, the OD increases with NPS while the wall thickness stays constant or increases. Using equations and rules in ASME B31.3 Process Piping, it can be shown that pressure rating decreases with increasing NPS and constant schedule. Some specifications use pipe schedules called standard wall (STD), extra strong (XS), and double extra strong (XXS), although these actually belong to an older system called iron pipe size (IPS). The IPS number
372-471: A low-stress work environment that the employee can associate him or herself positively with. Other incentives that should be implemented are generous vacation allowances or flexible work hours. When selecting a domain name , NPOs often use one of the following: .org , the country code top-level domain of their respective country, or the .edu top-level domain (TLD), to differentiate themselves from more commercial entities, which typically use .com . In
434-583: A metric name for existing inch sizes, resulting in a 1:1 correlation between NPS and DN sizes. ISO 6708 does not include values for "DN 6" or "DN 8", however ASME B36.10M list the "DN 6" and "DN 8" . Also, the European Standard EN 12 516-1 (Industrial valves - Shell design strength - Part 1: Tabulation method for steel valve shells) specifies the dimensions "DN 6" and "DN 8", respectively their equivalents NPS 1 ⁄ 8 "and NPS 1 ⁄ 4 ". (dimensionless) Tolerance: The tolerance on pipe OD
496-430: A national standards organization. According to Adam Stanton, the first permanent secretary and head of staff in 1919, AESC started as an ambitious program and little else. Staff for the first year consisted of one executive, Clifford B. LePage, who was on loan from a founding member, ASME. An annual budget of $ 7,500 was provided by the founding bodies. In 1931, the organization (renamed ASA in 1928) became affiliated with
558-457: A nonprofit entity without having tax-exempt status. Key aspects of nonprofits are accountability, integrity, trustworthiness, honesty, and openness to every person who has invested time, money, and faith into the organisation. Nonprofit organizations are accountable to the donors, founders, volunteers, program recipients, and the public community. Theoretically, for a nonprofit that seeks to finance its operations through donations, public confidence
620-424: A pipe is welded or bent the most common method to inspect blockages, misalignment, ovality, and weld bead dimensional conformity is to pass a round ball through the pipe coil or circuit. If the inner pipe dimension is to be measured then the weld bead should be subtracted, if welding is applicable. Typically, the clearance tolerance for the ball must not exceed 1 millimetre (0.039 in). Allowable ovality of any pipe
682-684: A self-selected board and a membership whose powers are limited to those delegated to it by the board. A board-only organization's bylaws may even state that the organization does not have any membership, although the organization's literature may refer to its donors or service recipients as 'members'; examples of such organizations are FairVote and the National Organization for the Reform of Marijuana Laws . The Model Nonprofit Corporation Act imposes many complexities and requirements on membership decision-making. Accordingly, many organizations, such as

Resource mismanagement is a particular problem with NPOs because the employees are not accountable to anyone who has a direct stake in the organization. For example, an employee may start a new program without disclosing its complete liabilities. The employee may be rewarded for improving
806-578: A wide diversity of structures and purposes. For legal classification, there are, nevertheless, some elements of importance: Some of the above must be (in most jurisdictions in the US at least) expressed in the organization's charter of establishment or constitution. Others may be provided by the supervising authority at each particular jurisdiction. While affiliations will not affect a legal status, they may be taken into consideration by legal proceedings as an indication of purpose. Most countries have laws that regulate

This will result in more money for the organization. The activities a nonprofit is partaking in can help build the public's confidence in nonprofits, as well as how ethical the standards and practices are. There

One way of managing the sustainability of nonprofit organizations is to establish strong relations with donor groups. This requires a donor marketing strategy, something many nonprofits lack. Nonprofit organizations provide public goods that are undersupplied by government. NPOs have

The organization also coordinates U.S. standards with international standards so that American products can be used worldwide. ANSI accredits standards that are developed by representatives of other standards organizations , government agencies , consumer groups , companies, and others. These standards ensure that

In the United States, to be exempt from federal income taxes, the organization must meet the requirements set forth in the Internal Revenue Code (IRC). Granting nonprofit status is done by the state, while granting tax-exempt designation (such as IRC 501(c) )

Many ANSI regulations are incorporated by reference into United States federal statutes (i.e. by OSHA regulations referring to individual ANSI specifications). ANSI does not make these standards publicly available, and charges money for access to these documents; it further claims that it

For example, employees of non-profit organizations pay taxes from their salaries, which they receive according to the laws of the country. NPOs use the model of a double bottom line in that furthering their cause is more important than making a profit, though both are needed to ensure

If no other test is conducted to verify ovality, or blockages, this test must be seen as a standard requirement . A flow test can not be used in lieu of a blockage or ball test. See pipe dimensional table, Specification ASME B36.10M or B36.19M for pipe dimensions per schedule. Stainless steel pipe is most often available in standard weight sizes (noted by

Although ANSI itself does not develop standards, the Institute oversees the development and use of standards by accrediting the procedures of standards developing organizations. ANSI accreditation signifies that the procedures used by standards developing organizations meet
1674-411: Is the remuneration package, though many who have been questioned after leaving an NPO have reported that it was stressful work environments and the workload. Public- and private-sector employment have, for the most part, been able to offer more to their employees than most nonprofit agencies throughout history. Either in the form of higher wages, more comprehensive benefit packages, or less tedious work,

With an increase in NPOs since 2010, organizations have adopted competitive advantages to create revenue for themselves to remain financially stable. Donations from private individuals or organizations can change each year and government grants have diminished. With changes in funding from year to year, many nonprofit organizations have been moving toward increasing

Private charitable contributions increased for the fourth consecutive year in 2017 (since 2014), at an estimated $ 410.02 billion. Out of these contributions, religious organizations received 30.9%, education organizations received 14.3%, and human services organizations received 12.1%.

But even indirect liabilities negatively affect the financial sustainability of the NPO, and the NPO will have financial problems unless strict controls are instated. Some commenters have argued that
2232-410: The NPS and schedule of a pipe, the pipe outside diameter (OD) and wall thickness can be obtained from reference tables such as those below, which are based on ASME standards B36.10M and B36.19M. For example, NPS 14 Sch 40 has an OD of 14 inches (360 mm) and a wall thickness of 0.437 inches (11.1 mm). However, the NPS and OD values are not always equal, which can create confusion. The reason for

ANSI's members are government agencies, organizations, academic and international bodies, and individuals. In total, the Institute represents the interests of more than 270,000 companies and organizations and 30 million professionals worldwide. ANSI's market-driven, decentralized approach has been criticized in comparison with more planned and organized international approaches to standardization. An underlying issue

The institute is the official U.S. representative to the two major international standards organizations, the International Organization for Standardization (ISO), as a founding member, and the International Electrotechnical Commission (IEC), via the U.S. National Committee (USNC). ANSI participates in almost the entire technical program of both
2418-461: The age of 16 volunteered for a nonprofit. In the United States, both nonprofit organizations and not-for-profit organizations are tax-exempt. There are various types of nonprofit exemptions, such as 501(c)(3) organizations that are a religious, charitable, or educational-based organization that does not influence state and federal legislation, and 501(c)(7) organizations that are for pleasure, recreation, or another nonprofit purpose.

In 2020, nonprofit organizations began using microvlogging (brief videos with short text formats) on TikTok to reach Gen Z, engage with community stakeholders, and overall build community. TikTok allowed for innovative engagement between nonprofit organizations and younger generations. During COVID-19, TikTok was specifically used to connect rather than inform or fundraise, as its fast-paced, tailored For You Page separates itself from other social media apps such as Facebook and Twitter. Some organizations offer new, positive-sounding alternative terminology to describe

2666-565: The community; for example aid and development programs, medical research, education, and health services. It is possible for a nonprofit to be both member-serving and community-serving. Nonprofit organizations are not driven by generating profit, but they must bring in enough income to pursue their social goals. Nonprofits are able to raise money in different ways. This includes income from donations from individual donors or foundations; sponsorship from corporations; government funding; programs, services or merchandise sales, and investments. Each NPO
2728-453: The discrepancy for NPS 1 ⁄ 8 to 12 inches is that these NPS values were originally set to give the same inside diameter (ID) based on wall thicknesses standard at the time. However, as the set of available wall thicknesses evolved, the ID changed and NPS became only indirectly related to ID and OD. For a given NPS, the OD stays fixed and the wall thickness increases with schedule. For

Most nonprofits have staff that work for the company, possibly using volunteers to perform the nonprofit's services under the direction of the paid staff. Nonprofits must be careful to balance the salaries paid to staff against
2852-432: The election of the board, there are few inherent safeguards against abuse. A rebuttal to this might be that as nonprofit organizations grow and seek larger donations, the degree of scrutiny increases, including expectations of audited financial statements. A further rebuttal might be that NPOs are constrained, by their choice of legal structure, from financial benefit as far as distribution of profit to members and directors
2914-475: The establishment and management of NPOs and that require compliance with corporate governance regimes. Most larger organizations are required to publish their financial reports detailing their income and expenditure publicly. In many aspects, they are similar to corporate business entities though there are often significant differences. Both not-for-profit and for-profit corporate entities must have board members, steering-committee members, or trustees who owe

ANSI also designates specific standards as American National Standards, or ANS, when the Institute determines that the standards were developed in an environment that is equitable, accessible and responsive to the requirements of various stakeholders. Voluntary consensus standards quicken the market acceptance of products while making clear how to improve

3100-480: The mid 20th century, permitted the use of thinner pipe walls with much less risk of failure due to corrosion. By 1949 thinner schedules 5S and 10S, which were based on the pressure requirements modified to the nearest BWG number, had been created, and other "S" sizes followed later. Due to their thin walls, the smaller "S" sizes can not be threaded together according to ASME code, but must be fusion welded , brazed, roll grooved, or joined with press fittings. Based on
3162-511: The money paid to provide services to the nonprofit's beneficiaries. Organizations whose salary expenses are too high relative to their program expenses may face regulatory scrutiny. A second misconception is that nonprofit organizations may not make a profit. Although the goal of nonprofits is not specifically to maximize profits, they still have to operate as a fiscally responsible business. They must manage their income (both grants and donations and income from services) and expenses so as to remain

While many established NPOs are well-funded and comparative to their public sector competitors, many more are independent and must be creative with which incentives they use to attract and maintain people. The initial interest for many

A notable exception to this involves churches , which are often not required to disclose finances to anyone, including church members. In the United States, nonprofit organizations are formed by filing bylaws, articles of incorporation , or both in the state in which they expect to operate. The act of incorporation creates a legal entity enabling

Nonprofits can have members, but many do not. The nonprofit may also be a trust or association of members. The organization may be controlled by its members who elect the board of directors , board of governors or board of trustees . A nonprofit may have

Charities and nonprofits are exempt from Corporation Tax as well as the trustees being exempt from Income Tax. There may also be tax relief available for charitable giving, via Gift Aid, monetary donations, and legacies. Founder's syndrome is an issue organizations experience as they expand.

NESCC is a joint initiative to identify and respond to the current need for standards in the nuclear industry. Nonprofit organization A nonprofit organization ( NPO ), also known as
3534-550: The public and private sectors have enjoyed an advantage over NPOs in attracting employees. Traditionally, the NPO has attracted mission-driven individuals who want to assist their chosen cause. Compounding the issue is that some NPOs do not operate in a manner similar to most businesses, or only seasonally. This leads many young and driven employees to forego NPOs in favor of more stable employment. Today, however, nonprofit organizations are adopting methods used by their competitors and finding new means to retain their employees and attract
3596-483: The receipt of significant funding from large for-profit corporations can ultimately alter the NPO's functions. A frequent measure of an NPO's efficiency is its expense ratio (i.e. expenditures on things other than its programs, divided by its total expenditures). Competition for employees with the public and private sector is another problem that nonprofit organizations inevitably face, particularly for management positions. There are reports of major talent shortages in
