China Gold Supplier for Brass Tank Fittings - Electric resistance welded ERW steel pipe – BESTOP

ERW steel pipe is one of the main pipe structural material in construction and liquid
transfer steel material. It is properly used in bridge building, underground transfer assemble structure, agriculture, chemical liquid transfer, oil and gas transfer and so on, It will be manufactured by electricity resistance welding. The outside surface can be treated by galvanizing, painting, PE coating, PP coating, HDPE coating and so on, The main advantage is welding beam can be very smooth. It is very good to do the transfer and liquid job. Normal usage validity time will be around 50-80 years. Standard can be API, ASTM, JIS etc.
ERW steel pipe divided into round and rectangle(square) pipes; just meet the different customer demand.

Low cost: the low raw material cost and manufacturing cost make it prices more competitive than longitudinal seam submerged-arc welded pipes and seamless pipes.
High weld seam security: As a result of special welding method of melting parent metal together, without filler metal, the weld property is better than submerged-arc welded pipes; and the weld seam is much shorter than spiral seam welded pipes, the seam security is greatly improved.
Wide range: ERW pipes can be applied with a wide range of thickness / diameter ratio, covering hundreds of specifications.
