A813
This standard is issued under the fixed designation A 813/A 813M; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A superscript epsilon ( ε) indicates an editorial change since the last revision or reapproval.

A814
This specification covers two classes of flanged and cold-bending quality cold-worked straight-seam single or double welded austenitic steel pipe intended for high-temperature and general corrosive services.

Comparison with Seamless Tubes

 

Feature	Welded Tubes (A813/A814)	Seamless Tubes (A213)
Manufacturing	Welded from strip or plate	Drawn or extruded from solid billet
Cost	Generally lower due to simpler process	Higher due to complex forming
Corrosion Resistance	Equivalent when properly annealed	Comparable for same grade
High-Pressure Use	Suitable for most applications, but may have limits vs. seamless	Better for extreme pressures

 

Applications

• Chemical Processing Industry: It is used to transport various corrosive chemical media, such as acids, alkalis, and salts, due to its excellent corrosion resistance.
• Food and Beverage Industry: It is suitable for use in the food and beverage industry because of its non - reactive nature, which helps to ensure the safety and quality of food and beverages.
• Oil and Gas Industry: It can be used for pipelines and equipment in the oil and gas industry, which can resist the corrosion of harsh environments such as oil, gas, and water.
