ERW steel pipe occupies a pivotal position in the field of transportation pipes in the world. So what are the requirements and advantages of ERW steel pipes during transportation?

In the production process of stainless steel welded pipe, improve its surface quality can effectively extend its service life. Improving the surface quality of stainless steel welded pipe includes improving the surface morphology and structure, reducing the number of interlayer, etc. So how to improve the surface quality of stainless steel welded pipe?

In the process of rectangular tube application, in order to prolong its service life, manufacturers will generally coat the surface of the rectangular tube with a protective film to reduce the loss caused by corrosion. So what are the factors affecting the rectangular tube coating?

The production process of seamless steel pipe can be divided into two types: cold-drawn and hot-rolled, and the production process of cold-rolled seamless steel pipe is generally more complicated than hot-rolled.

The square tube is rolled from strip steel through process treatment. Generally, the strip is unpacked, flattened, coiled, welded to form a round tube, and then rolled into a square tube from the round tube and then cut to the required length.

The square tube is rolled from strip steel through process treatment. Generally, the strip is unpacked, flattened, coiled, welded to form a round tube, and then rolled into a square tube from the round tube and then cut to the required length, and wear and tear will inevitably occur during their use, handling and transportation. So how to avoid the wear of the square tube?

Now everyone should know that when we use LSAW steel pipe, if the diameter of the steel pipe is small, we will prepare to expand the diameter, so do you know how to expand the diameter of LSAW steel pipe?

The way of forming a round tube is called bending, and the way of forming a square tube is called bending. There are 2 basic methods for bending and forming: solid bending and empty bending.
