Standard:
ASTM A192 / A192M / ASME SA192 / SA-192M
Uses:
suitable for high pressure with a minimum wall thickness Seamless Carbon Steel Boiler and Superheater Steel Pipe
Mainly the production of steel grades:
A192 SA192
by negotiation, also can supply other grades of steel pipe.

Seamless steel pipe manufacturing process. Seamless steel tubes according to their manufacturing process, divided into hot-rolled perforation diameter seamless steel pipe punching pulling seamless steel pipe vertical extrusion seamless steel pipe, the first two processes is the production of general-caliber seamless steel pipe seamless steel pipe cold drawn given caliber seamless steel pipe is generally 8-406, wall thickness generally 2mm-30mm; latter two is the production of large diameter seamless steel pipe, seamless steel pipe diameter is generally 406-1800, wall thickness of 20mm-220mm. Structure seamless steel tube boiler seamless steel pipe seamless steel tubes for fluid oil pipeline seamless steel pipe can be divided according to their use.
