Differences between ERW Steel Pipe and HFW Steel Pipe

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. ERW Black Steel Pipe - Steel Pipes and Tubes - Steel ERW Black Steel Pipes and tubes are used in various engineering purposes, fencing, scaffolding, line pipes etc. These tubes & pipes are available in varying qualities, wall thickness, diameters and finishes depending on the requirement of the end-users.

The terms pipes and tubes are often used interchangeably, but there are quite a few differences between pipe and tube:1. Pipes are generally measured by the inside diameter, often called the nominal diameter ( ASME/ANSI B 36.10 Welded and Seamless Wrought Steel Pipe), and a schedule, which refers to the wall thickness.

Steel Tubes and Pipes what are the main differences

Pipes are usually made of carbon steel or low alloy steel. Tubes instead are made of mild steel, aluminum, brass, copper, chrome, stainless steel, etc. The difference in materials is also a reason for the difference in the cost and applications. Some widely used steel pipe standards or piping classes are: The API range now ISO 3183.
