ASTM A53 seamless and welded steel pipe is a general, all-purpose pipe. Designed for coiling, bending and flanging, A53 carbon steel pipe is suitable for welding. The grades denote certain chemical and mechanical properties and should be noted in selection. A53 pipe is intended for mechanical and pressure applications and is also acceptable for ordinary uses in steam, water, gas and air lines, Low pressure systems, Structural applications, Mechanical components, Bollards, Casing, generator plants, refineries, compressor stations, natural gas transmission, and steam conduction.
Made from 1025 to 1030 Steel
Meets ASTM A53
ASTM A106 seamless steel pipe covers seamless carbon steel nominal wall pipe for high-temperature service, suitable for bending, flanging and similar forming operations. NPS 1-1/2 and under may be either hot finished or cold drawn. NPS 2 and larger shall be hot finished unless otherwise specified. Surface finish standards are outlined in the specification.
A106 pipe is always produced by the seamless method and can be bent, coiled and flanged and is intended for use in high temperature applications, Pressure systems, Mechanical components, Structural applications, Spreader bars.
