Hebei Galaxy Steel Pipe and Fittings Co.,Ltd has established a special electric resistance-welded tube factory dedicated to high-grade tubes for boilers and plants in order to conduct the full-scale production of high-grade electric resistance-welded (ERW) steel tubes equivalent to seamless steel tubes. Based on our preeminent steel-making technology and hotrolling equipment, we manufacture electric resistance welded steel tubes for boilers and heat exchangers that rivals or exceeds seamless steel tubes, all by adopting: tubemaking equipment designed for especially high-grade steel tubes,automatic welding control systems, various pieces of extremely highly reliable full-automatic nondestructive test equipment, and large-capacity bright heat treatment furnaces.
what is ERW steel pipe ?
Electric resistance welding (ERW) is a welding process in which metal parts in contact are permanently joined by heating them with an electric current, melting the metal at the joint.Electric resistance welded (ERW) pipe is made from steel coil and the weld seam runs parallel to the pipe.
Usually ERW pipe maximum OD is 24”(609mm), for larger dimensions pipe will be manufactured in SAW.

ERW steel pipe application and usage
ERW steel pipe used for transporting gas and liquid objects such as oil and gas, could meet the low and high pressure requirement. In recent years, with the development of ERW technology, more and more ERW steel pipe used in the oil and gas fields, automobile industry and so on.
