4 Inch High Pressure Seamless Mechanical Tubing ASTM A53M

4 Inch High Pressure Black Steel Pipe Tube ASTM A53M

Pipes are manufactured according to the standard of API, ASTM, ASME, EN, UNI, NFA, GB, domestic and international standards.Normally, when the pipe outer diameter is within 57mm, we usually use cold drawn pipes, while up to that 57mm, we use hot rolled.Materials: 10#, 20#, 45#, 16Mn, GrB, Q345B, X42-56, ST44, ST52 etc.ASTM A53/A53M-02 .Fluid delivery pipes are those with a hollow cross section and no welds from beginning to end.Fluid conveying pipe has a hollow section, a large number of pipes used for conveying fluid to transport oil, natural gas, gas, water and some solid material pipelines.

Normally, they are used for the industries including electricity, Sewage treatment water piping,chemical, petrochemical, boiler, heating, ship-building.Seamless and welded black steel and hot-dip galvanized steel pipe,ASTM A106-02A seamless carbon steel pipe for high-temperature operation, ASTM A161-94 Seamless steel distillation pipe of low-carbon and carbon-molybdenum steel for refining equipment.

Compared with solid steel such as round steel, fluid conveying pipe has the same bending and torsional strength and lighter weight. It is a kind of economic section steel, which is widely used in manufacturing structural parts and mechanical parts, such as oil drill pipe, automobile drive shaft, bicycle frame and steel scaffolding used in construction, etc.Using steel pipe to manufacture annular parts, can improve the material utilization rate, simplify the manufacturing process, save materials and processing hours, such as rolling bearing rings, jack sleeves, etc., has been widely used in fluid conveying with pipe to manufacture.
