In addition to being used for oil extraction, the emergence of oil casing pipe can also be used as a pipeline for transporting raw materials. In order to enhance the quality of oil casing, every link ...

Seamless steel pipe is the steel pipe with the largest consumption and the highest demand. The production volume and the manufacturer are the largest steel pipe types. In many cases, the competition o...

The biggest difference between straight seam high frequency electric resistance welded pipe (ERW Steel Pipe) and seamless steel tube is that ERW has a weld, which is also the key to the quality of ERW...

1. The main feature of seamless steel pipe is that it has no welds and can withstand greater pressure. The product can be a rough cast or cold drawn part. 2. Precision steel pipe is a product that has...

The scope of ASTM A106 and A53:  ASTM A53 specification covers the steel pipe manufacturing types in seamless and welded, material in carbon steel, black steel. Surface natural, black, and hot-dipp...

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

Electric resistance welded pipes (ERW steel pipe) are longitudinally welded from metal after moving it afterward. CDW pipes are produced by expelling the metal to the required length; Hence ERW pipes ...

After the tubing, casing pipe and line pipe are produced, the surface is usually sprayed with anti-corrosion paint (Varnish, coating), and the outer surface of the pipe is sprayed with a striking mark...

The details of ERW pipe evaluation process:  1. Non-destructive testing Rotate the detection arm of the inspection station into the straight seam welded pipe production line, observe the position of t...

The production of seamless steel pipes has a history of nearly 100 years. The use of steel pipes was started by a Scottish inventor in 1815 connecting the tubes to convey gas for lights. In 1836, the...
