Anchor Brand gas cylinders are made of quality manganese steel or alloy steel through solid drawn process with advanced workmanship and sophisticated facilities to turn the steel billets into cylinders, thus giving smooth and bright surface, homogeneous wall thickness and precise dimensions.
The steel cylinders are manufactured according to Chinese National Standard and inspected by China Boiler and High Pressure Container Supervisor which is an independent superintendent organization.
Avaliable for export are seamless steel gas cylinders with valves and caps for industrial gases: Oxygen, Argon, Hydrogen, Nitrogen, Helium, Freon, Carbon Dioxide, Liquefied Ammonia, and Oxygen for medical use, Welded Liquefied petroleum Gas Cylinders and Chlorine Cylinders etc.
Customers are always welcome to place orders with our corporation. Catalogues andinformation are available upon request.
