With the exploration and innovation of company people, gradually formed four major advantageous products: steel plate, steel pipe, stainless steel, special steel.
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.
Difference between ERW and HFW - Hunan Great Steel Pipe. Difference between ERW and HFW . ERW steel pipe: low-frequency or high-frequency resistance welding manufacturing process with a straight seam steel pipe; HFW steel pipe: frequency equal to or greater than 70kHz welding current welding ERW Pipe.

HFW(HIGH-FREQUENCY WELDED) CARBON PIPES PREFERRED, BETTER. A recently published article in the Wall Street Journal by Alison Sider referred to the oil pipeline failure in Mayflower, AR by saying the cause, according to the Pipelines and Hazardous Materials Safety Administration (PHMSA) website, can be attributed to ..some types of an early welding process called electric resistance welding.
To understand better HFW pipe, you should first know what is EW pipe. EW pipe refers to tubular product having one longitudinal seam produced by low- or high-frequency electric-welding. HFW pipe refers EW pipe produced with a welding current frequency equal to or greater than 70 kHz. (according to API 5L spec.) HFW pipe is kind of welded pipe hfw carbon steel pipe steels
The high-frequency welding for carbon steel welded pipe production has been 40 years of history. Having a large power supply power, high-frequency welding of different material, diameter and wall thickness of a steel pipe can reach a higher welding speed (highest ratio TIG welding speed is more than l0 times higher).

Predominant material for line pipes is C-Mn Steel or Carbon steel. The material for modern line pipes is high strength low alloy (HSLA) steel. The evolution of this special class of steels can be traced back to 1959 when the first X-52 micro-alloyed, or so called high strength low alloy (HSLA) steel was installed in North America. Prior to that hfw carbon steel pipe steels

For the record, the electric resistance welding (ERW) process is not just an early process, it is an ongoing process still used in a significant number of pipes, mostly 24-inch and below.
Steel classification is important in understanding what types are used in certain applications and which are used for others. For example, most commercial steels are classified into one of three groups: plain carbon, low-alloy, and high-alloy.
