High Frequency Electric Resistance Welding Carbon Stm A53 Grade B Pipe Steel Pipe

What is the HFW Steel Pipe?

It shall be noted that HFW pipe is a type of ERW pipe. High-frequency welding (HFW) steel pipe is that ERW pipe produced with a welding current frequency equal to or greater than 70 kHz. Through high-frequency current welding resistance, the heat generated in the contact objects, so the objected surface is heated to the plastic state, then with or without forging to achieve a combination of steels.

Typical process of high frequency welded pipe:

Slitting --- Uncoiling --- Strip leveling --- Head and tail shearing --- Butt welding of steel --- Storage material----Forming ----Welding --- Deburring --- Sizing --- flaw detection --- flying cutting --- initial inspection --- steel pipe straightening --- pipe section processing --- hydraulic pressure test --- flaw detection --- printing and coating --- the finished product.

HFW is Required in API 5L PSL2 ERW Steel Pipe

According to the API 5L and ISO 3183 specification, for PSL 2 pipes in welded process, the HFW welding is a mandatory requirement for ERW steel pipes. As it is an improvement from the inherent problems of hardness, lack of fusion and susceptibility of stress corrosion cracking (SCC).
