Comparative Analysis of Seamless Casing Pipe and ERW

Aug 25, 2020 · According to the manufacturing method, the steel pipe can be divided into two categories:seamless steel pipe and welded seam steel pipe. Among them, ERW steel pipe is the main variety of welded steel pipe. Today, we mainly talk about two kinds of steel pipes used as raw materials for petroleum casing:seamless casing and ERW casing. Difference Between Seamless and Welded/ERW PipesPerformance and Usage:Seamless steel pipe has better pressure capacity, strength is higher than ERW welded steel pipe. So it is widely applied in high pressure equipment, and thermal, boiler industries. Generally the welding seam of the welded steel pipe is the Differences between ERW Steel Pipe and HFW Steel PipeHigh 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 are heated to the plastic state, then with or without forging to achieve a combination of steels.
