Pipeline Field Black X42M PSL2 High Frequency Welded Pipe

In the last few years, ERW pipes are have become an efficient alternative to seamless pipes, both in terms of price and performance, due to the modern welding technologies adopted by ERW pipe manufacturers (example HFI and HFW, high-frequency welding). These advancements in welding technologies have reduced, over time, the technical superiority of seamless pipes vs ERW pipes, making them interchangeable at least in some applications (low/medium pressure and temperature). Of course, seamless pipes will always benefit from the intrinsic superior mechanical strength of steel billets vs. coils and plates.

ERW steel pipe is short name of high frequency electric resistance welded pipe and made from raw material hot rolled steel plate by the continuous forming, bending, welding, heat treatment, sizing, straightening and cutting process. The advantages: compared with SSAW steel pipe, ERW pipe has high dimensional accuracy, uniform wall thickness, good surface quality, high pressure resistant performance etc. But ERW steel pipe can be only used in production of small diameter thin wall pipe, which is widely used in fields of gas and crude oil transportation in the city.

Due to their properties and prices, ERW pipes are most actively used to solve the following tasks: transportation of water, oil, gas, and other media with varying degrees of aggressiveness and reinforcement of various structures in the construction industry. Since the most important requirement for buildings is their reliability, pipes with a square cross-section are typically used in this area.
