What are ERW steel tubes and sawn steel tubes
ERW steel pipe
ERW steel pipe is a type of resistance welded steel pipe, high frequency resistance welding abbreviation.
For ERW, ERW is the corresponding English word beginning letter. Resistance welded tubular steel is divided into AC welded steel tube and DC welded steel tube two forms.
AC welding in accordance with the frequency is divided into low frequency welding, intermediate frequency welding, ultra IF welding and high frequency welding. High frequency welding is mainly used for thin-walled steel tubes.
Or ordinary wall thickness of production, high-frequency welding is divided into contact welding and induction welding.
DC welding is generally used for small diameter steel pipe.
Therefore, a high frequency welded tube is generally included in the ERW tube, a high frequency welding method for making an ERW tube. ERW longitudinal welding pipes are the most advanced and economical steel pipes in the field of oil and gas storage and transport.
SAW steel pipe
SAW Steel Pipe SAW Whole Name Submerged Arc Welding Steel Pipe It is an underwater arc welding process using steel pipe, the process produces a very high current density, the flux coating to prevent the rapid loss of heat and its focus on welding area. Underwater arc welding is widely used in the manufacture of pressure vessels, pipe fittings, beams and column, low-pressure fluid, steel structure engineering, with high quality, high production efficiency, no arc and dust.
SAW steel tube main products are steel tubes LSAW Longitudinally Submerged Arc Welding Steel Pipe straight seam double-sided under water arc welded steel pipe, the use of underwater arc welding technology for the production of straight seam steel pipe.
