What does EFW stand for in pipe?
electric fusion welding
Stainless Steel Efw Welded Pipe is a type of stainless steel pipes that is produced through electric fusion welding. The electric fusion welding is a process in which high voltage electricity is passed onto the material to heat and melt it.
What is EFW stainless pipe?
What is EFW Stainless Pipe? EFW, which is short for electric fusion welding, is one form of submerged arc welding. It is a technique that using metal heating between one or several consumable electrodes and the workpiece to combine the metal. And the arc will melt the metal and the filling materials.
What is the difference between ERW and EFW pipe?
The weld of the high-quality ERW welded pipe can reach the same level of toughness as the base metal, which cannot be achieved by the submerged arc welding process. EFW steel pipe is the abbreviation of electric fusion welding.
How is EFW pipe made?
In EFW welding process, the external high energy electric arc is used to create a weld joint. Once the welding is done, the excess weld material from outside and inside of the pipe is removed with the help of trimmer tools.
What is ERW and EFW?
Does EFW pipe have a seam?
EFW steel pipe is formed by rolling plate and welding the seam. The weld flash can be removed from the outside or inside surfaces using a scarfing blade. The weld zone can also be heat treated to make the seam less visible.
Is HFW the same as ERW?
ERW pipe manufacturing process includes HFW. ERW have low, medium, high frequency welding processes, and HFW is specially for high-frequency electric resistance welding. The differences between ERW and HFW steel pipe, is EFW is a type of ERW process for ordinary and thin-wall thickness steel pipes.
What is HFW pipe?
High frequency welding (HFW) is mainly used for ordinary or thin-walled steel pipes. It includes contact welding and induction welding. DC welding is usually used for small diameter steel pipes. Generally, HFW is one of ERW production methods, which uses high-frequency welding technology.
What does EFW mean in welding?
An Electric Fusion Welded (EFW) Pipe is a welded pipe formed by rolling plate and welding the seam. EFW is a process in which metal is heated by electrodes (filling metal) and the electric arc is used to make the welding.
Is ERW and HFW the same?
ERW have low, medium, high frequency welding processes, and HFW is specially for high-frequency electric resistance welding. The differences between ERW and HFW steel pipe, is EFW is a type of ERW process for ordinary and thin-wall thickness steel pipes.
