octalsteelDifferences 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 are heated to the plastic state,then with or without forging to achieve a combination of steels.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.What is the difference between HFW and ERW?Require the use of high-quality steel pipe weld heat treatment online or offline,so that the weld zone structure refinement,quality ERW pipe weld and base metal may reach the same level of toughness,which is submerged arc welding process can not be achieved.What is the difference between HFW and ERW?High-frequency welding (HFW) is a solid resistance heat energy.The use of high-frequency current welding resistance heat generated in the workpiece so that the workpiece is heated to melt the welding area or near the surface of the plastic state,then applied (or not applied) forging force and achieve a combination of metals.

What is a HFW steel pipe? - ugsteelmill

The 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.What is HFW steel pipe?It should be noted that HFW pipe is a type of ERW pipe.High frequency welding (HFW) is a solid resistance heat energy.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.What is HFW Steel Pipe? - Supply Chain QuarterlyOct 28,2020 erw hfw steel pipe#0183;It should be noted that HFW pipe is a type of ERW pipe.High frequency welding (HFW) is a solid resistance heat energy.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.
