Large Diameter Thick Wall Carbon Seamless Fluid Steel Pipe

Short Description:

The production and manufacturing process of thick-walled seamless steel pipe production can be divided into four basic ways: cold-drawn, cold-rolled, hot-rolled, and hot-expanded. The material of the steel pipe is 10#, 20#, 35#, 45# called ordinary steel pipe. Seamless steel pipe is expressed in terms of outer diameter, wall thickness, thick-walled seamless steel pipe mainly used for machining, coal mining, hydraulic steel, and many other applications.

The thick wall seamless steel pipes made of 10 #, 20 #, 35 # and 45 # are called ordinary steel pipes and alloy steel pipes.

Classification

Hot rolled thick wall seamless steel tubes, cold rolled thick wall seamless steel tubes, cold drawn thick wall seamless steel tubes, extruded thick wall seamless steel tubes, and stainless steel seamless steel tubes for pipe jacking structures (GB/T14975-2002) are seamless steel tubes for general and mechanical structures, widely used in chemical, petroleum, light textile, medical, food Hot rolled (extruded, expanded) and cold drawn (rolled) seamless steel tubes made of stainless steel for corrosion resistant pipes, structural members and parts in machinery and other industries.

Seamless stainless steel pipe for fluid transportation (GB/T14976-2002) is a general seamless steel pipe used to transport water, oil, gas and other fluids. It is usually a hot rolled (extruded, expanded) and cold drawn (rolled) seamless steel pipe made of stainless steel.

The special-shaped seamless steel pipe is the general name of the seamless steel pipe with other cross section shapes except the round pipe. According to the different shapes and sizes of steel pipe sections, it can be divided into uniform wall thickness profiled seamless steel pipe (code D), unequal wall thickness profiled seamless steel pipe (code BD), and variable diameter profiled seamless steel pipe (code BJ). Special shaped seamless steel pipe is widely used in various structures, tools and mechanical parts. Compared with round pipes, special-shaped pipes generally have larger inertia moment and section modulus, greater bending and torsion resistance, which can greatly reduce the structural weight and save steel.

Product Display

The biggest difference between thick-walled seamless steel pipe and thin-walled steel pipe is the wall thickness of the steel pipe. Generally speaking, thin-walled steel pipes are cold drawn, while thick-walled seamless steel pipes are generally hot-rolled.
