What are the advantages of seamless carbon steel pipe?

We have mention the definition of hot rolling seamless steel pipe will continue to talk about the advantages and disadvantages of hot rolling seamless steel tube with all of you.

The main manufacturing technology of seamless carbon steel pipe

The production equipment consists of punching machine, automatic pipe rolling machine, coiling machine, sizing machine and reducing machine.

Flattening test performance of ERW pipe

Flattening and cracking of ERW pipe welds are caused by insufficient weld strength, toughness or ductility.

Flattening test performance of ERW pipe

Flattening and cracking of ERW pipe welds are caused by insufficient weld strength, toughness or ductility.

Manufacturing methods and main uses of seamless pipes

The manufacturing method is the same as that of seamless steel pipes, but there are certain strict requirements on the steel grades used in the manufacture of steel pipes.

Uses of seamless pipe

The seamless steel pipe is made of perforated whole round steel, and the steel pipe without weld seam on the surface is called seamless steel pipe.

The basic principle of welding ERW pipe

High-frequency welding originated in the 1950s. It is a new welding process that uses the skin effect and adjacent effect generated by high-frequency current to connect steel plates and other metal materials.

Types of heat exchanger tube

The heat exchange tube is one of the elements of the heat exchanger, which is placed in the cylinder and used for heat exchange between the two media.
