Production Standard of High Frequency Straight Seam

Performance characteristics of high frequency straight seam welded pipe1. The biggest feature is high production efficiency, fast heating speed, no filler metal. 2. ERW welded pipe is easier to achieve quality control. The produced steel pipe has high dimensional accuracy and small deviations in outer diameter and wall thickness. 3.Spiral Steel Pipes for Sales from leading Spiral Steel The third, the spiral tubes match to high fatigue strength as same as seamless steel pipes and electric resistance welded pipes (ERW pipe). The fourth, the size is accurate, the diameter tolerance is less than 0.12%, the deflection is less than 1/2000, and the ellipse is less than 1%.Differences between ERW Steel Pipe and HFW Steel PipeThe high frequency welding (HFW) is mainly used in ordinary or thin wall steel pipe. It includes contact welding and induction welding. Direct current welding is generally used for small caliber steel tubes. In general, HFW is one of ERW production methods, it adopts the high frequency welding process. So, ERW steel pipe includes HFW steel pipe.

Electric Resistance Welded Pipe, ERW Steel Pipes, Electric

High frequency electric resistance welding (ERW) steel pipe production, internal weld surface treatments are generally incomplete curettage (left weld reinforcement) and complete curettage (scraping will form the inner surface of the groove) in two ways, and the results were not ideal, will affect the overall performance of the steel pipe.Differences Between ERW Steel Pipe and HFW Steel 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.Medium Black Steel Pipe Handy Steel StocksPipe made in Black AS1163 C250LO Grade C250 Pipe, for general mechanical and low pressure reticulation applications, is manufactured by cold forming and high frequency Electric Resistance Welding. The cold forming process enhances the strength, hardness and surface finish of the pipe and produces product to tight dimensional tolerances.

Pipe made in Black AS1163 C250LO Grade C250 Pipe that has been galvanized. For general mechanical and low pressure reticulation applications, the pipe is manufactured by cold forming and high frequency Electric Resistance Welding.PHMSAStakeholder Communications Manufacturing ProcessIn 1970, the low frequency process was superseded by a high frequency ERW process which produced a higher quality weld. Over time, the welds of low frequency ERW pipe was found to be susceptible to selective seam corrosion, hook cracks, and inadequate bonding of the seams, so low frequency ERW is no longer used to manufacture pipe.The Development Process of ERW Steel Pipe at Home and In the past ten years, Japan's ERW welded pipe has developed rapidly. Nippon Steel & Steel Corporation, Sumsei Metals and Wakayama Ironworks each have a 508 mm (20 in) ERW welded pipe production plant; Kawasaki Chita Steel Works and Japan Steel Pipeline Keihan Steel Works each have a 609 mm (24 in) ERW welded pipe production line.
