ASTM A269 Tubing
FAQ
ASTM A269 materia refers to ASTM A269 seamless and welded austenitic stainless steel tubing, a material widely used in general service applications such as the transport of gas, water, oil, and other fluids.The A269 standard specifies the material, chemical composition, mechanical and physical property requirements for austenitic stainless steel mechanical tubing for use in general service, as well as methods of tube fabrication, test requirements, and marking requirements.
ASTM A269 standard applies to general-purpose seamless and welded austenitic stainless steel tubes, widely used in a variety of equipment and tubing, including bright tubes and coils, etc. ASTM A249 standard is specifically designed for welded austenitic steel boilers, superheaters, Heat exchangers and condensers and other pressure piping stainless steel welded tube.
ASTM A269 applies to stainless steel tubing for general purposes and is written as ASTM A269 – Standard Specification for General Purpose Seamless and Welded Austenitic Stainless Steel Tubing. ASTM A270 applies to stainless steel tubing for sanitary facilities and is written as ASTM A270 – Seamless and welded austenitic and ferritic/austenitic stainless steel tubes for sanitary facilities
ASTM A269 is suitable for general purpose austenitic stainless steel seamless and welded tubes, which are widely used in various industrial fields, such as chemical, petroleum, food processing, water treatment and so on. ASTM A213 is mainly used for high-temperature applications, such as boilers, heat exchangers, high-pressure equipment, etc. It is suitable for applications in high-temperature environments
The working pressure rating of stainless steel tube under ASTM A269 is determined by multiplying its yield strength value by a safety factor of 0.94. Specifically, the working pressure for inch seamless stainless steel tube is based on the yield strength value of the tube in the ASTM A269 standard (20,000 psi or 137,800 KPa) multiplied by 0.94. For metric seamless stainless steel Tube, the working pressure is based on the Tube standard in ASMEB31.3 EN ISO1127 calculations, yield strength of 1370bar (20000psi), tensile strength of 5170bar (75000psi), the same multiplied by 0.94 to get the working pressure.
