CODES Code
The term referred to as a document covering a specific area of \u200b\u200bindustry, government has accepted and provides a basis for fincar legal obligations on individuals.
B31 ASME Code applied in piping for petroleum industry consists of a set of sections that are published separately: B31.3 Process Piping
applies to pipe refining plants, chemical, pharmaceutical, etc., And processing plants and terminals.
B31.8 Gas Transportation and Distribution Piping Systems applies to pipeline for transportation of products, mainly gas, between the source and terminals, whether these compression, regulation or measurement.
Example: "ASME B31.3 2002"
STANDARDS A standard set of geometric features which should accessories to meet so as to allow their exchange and its dimensions are known. The run in pipes are prepared by ASME, API and MSS
Example: "ASME 16.11" SPECIFICATIONS
The specification indicates the chemical composition, manufacturing process, heat treatment, destructive and nondestructive testing, mechanical properties and tolerances dimensional fabrication which must meet a pipe fitting. The most important used are those published by ASME, API and MSS
Example: "ASTM A106", "API 5L" A2A_F754.
PRACTICES RECOMMENDED
Best practices indicate reliable processes for the development of specific work that can range from the refurbishment of valves and pipe bending to test and thermal treatments. We recommended practices primarily API and PFI. Below are the documents PFI. ES2
