Carbon Steel Pipes
A/SA106
NPS 1/4 ″- 30 ″.
Schedules 10 via 160, Sexually Transmitted Disease, XH as well as XXH.
Scope.
ASTM A106 Seamless Pressure Pipeline (also known as ASME SA106 pipeline) covers smooth carbon steel small wall pipeline for high-temperature company. Suitable for flexing, flanging and similar creating operations.
NPS 1-1/2 ″ and also under might be either hot finished or chilly drawn. NPS 2 ″ as well as bigger shall be hot completed unless otherwise specified.
Process.
Killed steel, with primary melting process being open-hearth, basic-oxygen, or electric-furnace, potentially integrated with different degassing or refining.
Steel cast in ingots or strand cast is permissible.
Hot-finished pipeline need not be heat treated.
Cold-drawn pipeline shall be warmth treated after the last chilly draw pass.
