Seamless pipes by applications

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…

Boiler tubes

Boiler tubes are tubes used for boiler systems, like boilers for civil use in life, general industrial boilers, locomotive boilers and thermal power boiler.

 

Heat exchange tubes

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.
