Classification of round steel pipes



The round steel tube is a steel that is open at both ends. It has a hollow concentric circular section, which is quite large relative to the circumference.It can be used in pipelines, thermal equipment, machinery industry, petroleum geological drilling, containers, chemical industry and special applications.
Classification of round steel pipe
According to production methods can be divided into seamless round steel pipe and welded round steel pipe.
Seamless round steel pipe manufacturing process
Tube Blanks - Inspection - Peeling - Inspection - Heating - Perforation - Pickling - Grinding - Lubrication Air Drying - Welding Head - Cold Drawing - Solution Treatment - Pickling - Pickling Passivation - Inspection
Welding round steel pipe manufacturing process
Strip - Inspection - Shear - Length - Qualitative - Welding - Smoothing - Length - Inspection

Seamless Stainless Steel Tube for High Temperature Applications

Seamless stainless steel pipes are the preferred choice for high-temperature applications across industries due to their several superior properties. They possess greater strength under loading, exhibit exceptional corrosion resistance, can withstand shocks and vibrations, and offer reliable performance even under the toughest and harsh conditions. Due to these benefits, seamless stainless steel tubes and pipes are used in heating-pipelines, containers, coal-saving devices, super-heaters and repeaters, high press boiler, heat exchanger and condenser tubes, mechanical and structural tubing, among several others. This post discusses the various material grades of stainless steel used for producing these   seamless pipes   and tubes. Grades of Stainless Steel Used in Producing Seamless Tubes and Pipes Steel tubes and pipes used for the high-temperature applications must be of superior quality to resist high temperatures ranging from 400 degree Celsius to 1100 degree Celsiu...
