Welded Steel PipeClassification and Production Methods

How is the Welded Steel Pipe Made?

Welded steel pipe is a seamed steel pipe. The production process is to bend the pipe blank (steel plate and steel strip) into a tube of the required cross-sectional shape and size by various forming methods, and then weld the weld by different welding methods. The process of obtaining a steel pipe. Compared with seamless steel pipes, welded Welded Steel PipeClassification and Production Methods What are steel pipes?What are steel pipes?Steel pipes are long, hollow tubes that are used mainly to convey products from one location to another. They are produced mainly by two distinct manufacturing methods which result in either a welded pipe or seamless pipe. In both the manufacturing methods, raw steel is first cast into a more workable starting form (hot billet or flat strip).Introduction to Welded Pipe Manufacturing - The Process Piping What is ERW pipe welding?What is ERW pipe welding?At the end of rolling assembly, this pipe is continuously welded by welding machine. ERW/EFW and HFW are welding methods in which pipe is welded without adding filler material. However, EFW welding method can be used with filler material also.

HistoryDesignRaw MaterialsThe Manufacturing ProcessQuality ControlPeople have used pipes for thousands of years. Perhaps the first use was by ancient agriculturalists who diverted water from streams and rivers into their fields. Archeological evidence suggests that the Chinese used reed pipe for transporting water to desired locations as early as 2000 B.C. Clay tubes that were used by other ancient civilizations have been discovered. During the first century A.D. , the first lead pipes were constructed in Europe. In tropical countries, bamboo tubes were used to transport water.

Then current is passed between the two edges of the steel cylinder to heat the steel to a point at which the edges are forced together to form a bond without the use of welding filler material. Several Electric Resistance Welding (ERW) processes are available for pipe production. The two main types of ERW are 1. See more on theprocesspipingPipe Manufacturing Process / Methods for Seamless & A welded pipe can be manufactured in large sizes without any upper restriction. Welded pipe with filler material can be used in the manufacturing of long radius bends and elbow. Welded pipes are cheaper with compared to the seamless pipe and also Weak due to the weld. There are different welding methods used to weld the pipe.
