We can makes and markets cold-drawn and hot rolled seamless steel pipes and cold-drawn special-section seamless pipes which are widely applied in the industries of petrochemical, boiler, automobile, mechanica...
by Standards
Heat exchange tubes are intended for heating or cooling process fluids, they are for example suitable for closed circuit cooling of electrical equipment using demineralised water and for cooling water soluble oil solutions in quenching tanks.
ASTM A213 T5b Standard covers seamless ferritic and austenitic steel boiler, superheater, and heat-exchanger tubes.
20G seamless steel pipe is a high-quality carbon structural steel, boiler material
ASTM A335 P22 alloy steel pipe shall be suitable for bending, flanging, and similar forming operations, and for fusion welding.
Hot-rolled seamless steel pipe production base deformation process can be summarized as three stages: perforation, extension and finishing.
ASTM A179/A179M, ASME SA179/SA179M is the standard applicable to
Seamless cold drawn low carbon steel heat exchanger and condenser tubes.
Seamless pipes are extensively applied for the nuclear device, gas, petrochemical, ship building and boiler industries. Seamless pipes dominates 65% of market share in Chinese boiler industry.
Condition on delivery:
Cold-finished/hard
(cold-finished as-drawn)
BK
No heat treatment after the last cold-forming process. The tubes therefore have only low deformability.
