Alloy tube can be divided into: low alloy tube, alloy structure tube, high alloy tube, heat resistant acid stainless tube, high temperature alloy tube.

Steel tubes for pipeline, thermal equipment, mechanical industry, petroleum, geological drilling, container, chemical industry, special purpose steel tubes, other purposes.

Manufacturing process is different, and divided into hot rolled (extrusion) seamless steel tube and cold drawn (rolled) seamless steel tube two.

Hot rolled seamless steel tubes are classified into general steel tubes, low and medium pressure boiler tubes, high pressure boiler tubes, alloy steel tubes, stainless steel tubes, petroleum cracking tubes, geological tubes and other steel tubes.

Cold rolled (dial) seamless steel pipe in addition to general steel pipe, low and medium pressure boiler steel pipe, high pressure boiler steel pipe, alloy steel pipe, stainless steel pipe, petroleum cracking pipe, other steel pipe, also includes carbon thin-walled steel pipe, alloy thin-walled steel pipe, stainless steel pipe, special-shaped steel pipe.The criteria include:GB/T8162-2008 (seamless steel tube for structure), GB/T8163-2008 (seamless steel tube for fluid transportation), GB3087-2008 (seamless steel tube for low and medium pressure boiler), GB5310-2008 (seamless steel tube for high pressure boiler), GB5312-2009 (seamless steel tube for carbon steel and carbon manganese steel for ships), GB6479-2013 (seamless steel tube for high-pressure fertilizer equipment), etc.If you are interested in our products, please contact us by email.
