ASTM A192 High Pressure Seamless Steel Pipe
ASTM A192 high pressure seamless steel pipe is a seamless steel pipe designed for high pressure boilers and superheaters. Here is a detailed overview of ASTM A192 high pressure seamless steel pipe:
Standard: ASTM A192/A192M
Scope of application: Applicable to carbon steel seamless boiler tubes and superheater tubes with minimum wall thickness for high pressure.
OD (outer diameter) range: 6.00mm-177.8mm
WT (wall thickness) range: 1.00mm-25.4mm
Length range (per tube): 14000mm Max.
Manufacturing process
ASTM A192 seamless steel pipe adopts seamless steel pipe production process, which can be hot rolled steel pipe or cold drawn steel pipe. Hot rolled steel pipe does not need heat treatment, while cold drawn steel pipe needs heat treatment at 650℃ or higher after the last cold drawing.
