A53 PIPE MATERIAL

ASTM A53 pipe is always produced by the seamless method and can be bent, coiled and flanged. In sizes less than 2″ is it usually produced as a cold drawn product. 2″ and up are usually hot finished. ASTM A53 pipe is intended for use in high temperature applications. A53 Gr. B is intended for high temperature service (up to 750 Deg F). It just applies to seamless steel pipe with killed steel. Pipe of NPS 1 1/2” and under may be either hot finished or cold drawn. Unless specified, pipe on and over NPS 2″ shall be furnished hot finished, while A53 and API 5L are not.

BLACK PIPE FOR LOW PRESSURE APPLICATIONS

Black Steel Pipes offered provide suitable support in applications involving low pressure liquid delivery 

APPLICATIONS OF A53 PIPE

ASTM A53 seamless pressure pipe (also known as ASME SA53 pipe) is commonly used in the construction of oil and gas refineries, power plants, petrochemical plants, boilers, and ships where the piping must transport fluids and gases that exhibit higher temperatures and pressure levels.
