ASME B31.3 contains requirements for piping typically found in petroleum refineries; chemical, pharmaceutical, textile, paper, semiconductor, and cryogenic plants; and related processing plants and terminals. It covers materials and components, design, fabrication, assembly, erection, examination, inspection, and testing of piping.

Power Piping


ASME B31.1 prescribes minimum requirements for the design, materials, fabrication, erection, test, inspection, operation, and maintenance of piping systems typically found in electric power generating stations, industrial and institutional plants, geothermal heating systems, and central and district heating and cooling systems.



This ASME Standard provides the requirements applicable to the design and construction of new fluid processing equipment used in industries that require a defined level of purity and bioburden control. It covers materials, design, fabrication, inspections, testing and certification.



This standard is to provide procedures for welding stainless steels and other corrosion resistant metals and alloys (CRAs) for fluid (liquid or gas) distribution systems in semiconductor manufacturing applications. Welds performed following these procedures are of sufficient quality to provide the required system purity, weld integrity, and weld strength for use in semiconductor manufacturing applications



This standard covers the gas and arc welding of butt, fillet, and socket welds in carbon and low-alloy steel piping used in the compression, pumping, and trans-mission of crude petroleum, petroleum pro-ducts, fuel gases, carbon dioxide, nitrogen and, where applicable, covers welding on distribution systems. It applies to both new construction and in-service welding. The welding may be done by a shielded metal-arc welding, gas metal-arc welding, flux-cored arc welding, plasma arc welding, oxyacetylene welding, or flash butt welding process or by a combination of these processes using a manual, semiautomatic, mechanized, or automatic welding technique or a combination of these techniques. The welds may be produced by position and roll welding.

Guides/Recommended Practices

Specification for welding austenitic stainless steel pipe systems in sanitary (Hygienic) applications


This document outlines welding standards for use in the manufacture and construction of dairy and food product processing plants. Compiled at the request of the 3A Sanitary Standards Committee, which develops sanitary design standards for dairy and food processing, packaging, and handling equipment and systems. Covers the requirements for gas tungsten arc welding GTAW of austenitic stainless steel tube and pipe at least inch 6 mm in diameter in the fabrication and construction of new sanitary hygienic processing systems. The specification list the required essential and nonessential variables for a written welding procedure qualification WPS, and acceptance criteria for procedure qualification for visual and mechanical testing of welds. ANSI Approved. ISBN 978-0-87171-749-8

Guide for Multipass Orbital Machine Pipe Groove Welding


The Standard Guide for Multipass Orbital Machine Pipe Groove Welding, AWS D10.14M/D10.14:2010, provides an overview of the subject. The guide presents several aspects of multipass orbital machine pipe groove welding. Among the aspects presented are: arc welding processes, pipe beveling, pipe line up and welding equipment’s, nondestructive examination, consumable estimation, maximum repair length, and preparation for welding. Multipass orbital machine pipe groove welding of both plant pipe welding and transmission pipe welding are discussed.

Recommended Practices for Gas Tungsten Arc Welding of Titanium Pipe and Tubing


Incorporates results of research on the effects of atmospheric exposure during welding. Recommended maximum exposure temperature has been lowered and the effects of high temperature exposure have been revised. Provides coverage on power sources, tungsten electrodes, titanium base metal grades, filler metals, joint design and preparation, pickling and cleaning, fitting and tacking, preweld cleaning, gas shielding, welding procedures and techniques, and preheat and post-weld heat treatment. Also includes information on weld quality tests and safety. ANSI Approved. ISBN 0-87171-623-2

Guide for the Fusion Welding of Titanium and Titanium alloys


The standard Guide for the Fusion Welding of Titanium and Titanium Alloys provides instructional guidance for the welding of titanium and titanium alloys. This guide explains processes, equipment, materials, workshop practices, joint preparation, welding technique, tests, and the repair of defects. ISBN 0-87171-055-2

Guide for Welding Ferritic/Austenitic Duplex Stainless Steel Piping and Tubing


This standard presents a detailed discussion of the metallurgical and welding characteristics and weld-ability of duplex stainless steel used in piping and tubing. A number of tables and graphs are presented in order to illustrate the text. ISBN 978-0-87171-088-8
