What Welding Rod is Used for Seamless Steel Pipe? How is the Welding Done?
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...
Characteristics of Weld Seam of ERW Steel Pipe
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...
Differences between Precision Steel Pipe and Seamless Steel Pipe
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...
Differences between ASTM A53 and ASTM A106 Steel Pipe
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...
Principle of High Frequency DC Resistance Welding (ERW)
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...
What is the Difference between ERW and CDW Pipes?
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 ...
