Piping standards define application design and construction rules and requirements for piping components as flanges, elbows, tees, valves etc. A standard has a limited scope defined by the standard. The difference between piping codes and piping standards can be defined as: Piping Standards. Piping codes define the requirements of engineering, design, fabrication, use of materials, tests and inspection of pipes and piping systems.

Typically, the pipe wall thickness is the controlled variable, and the Inside Diameter (I.D.) is allowed to vary. The pipe wall thickness has a variance of approximately 12. American National Standard Institute (ANSI) American Society of Mechanical Engineers (ASME) ASME B 31.

Piping and related component standards developed by the Manufacturer’s Standardization Society. The MSS standards are directed at general industrial applications. The pipeline industry makes extensive use of these piping component and quality acceptance standards. The piping components are designed and manufactured to the industry standards to: Ensure the consistency of the material properties and specifications. Specify service ratings and allowable.

LANL Engineering Standards Manual PD3Chapter Pressure Safety. Process Piping Guide Rev. Gasket and Packing a) The designer is responsible for assuring that the flange and valve gaskets and valve stem packing are adequate for the intended service. The design pressure-temperature to be used as a basis for the design of piping system and selection of standard piping material components shall be in accordance with the requirements of the ASME B31.

Power Piping” (ASME Section I) or other governing codes. NPS = Nominal Pipe Size O. Standard : Pipe size is specified by two designations: a nominal pipe size (NPS) for diameter based on inches, and a schedule (Sched. or Sch.) for wall thickness. 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). Piping is governed by International Codes and Standards. Which codes and standards to be referred for a given projects depends on client preferences and local regulations.

Here is a list of some of the international codes and standards followed widely world over.

The following codes and standards shall be used together with this standard specification for materials, design and dimensional requirements. ASME BCode for Pressure Piping and it applies to piping systems that transport chemicals, petroleum products, fluidized solids, refrigerants, cryogenic fluids, and gas, steam, air, and water. This Standard covers design, material, manufacturing, testing, marking, and inspection requirements for factory-made pipeline bends of carbon steel materials having controlled chemistry and mechanical properties, produced by the induction bending process, with or without tangents. Leak Testing of Assembled Piping. ASME’s most requested codes.

Together, they remain essential references for anyone engaged with piping. Some Useful Codes and Standards Organizations. ANSI provides a forum for development of American national standards. API - American Petroleum Institute. The American Petroleum Institute - API.

Piping for industrial plants and marine applications. This code prescribes minimum requirements for the design, materials, fabrication, erection, test, and inspection of power and auxiliary service piping systems for electric generation stations, industrial institutional plants, central and district heating plants. Piping sometimes refers to piping design, the detailed specification of the physical piping layout within a process plant or commercial building.

In earlier days, this was sometimes called drafting , technical drawing , engineering drawing , and design, but is today commonly performed by designers that have learned to use automated computer-aided drawing or computer-aided design (CAD) software.
