We are committed to providing one-stop service for steel pipe products to customers around the world.
LSAW (Longitudinally Submerged Arc Welded Steel pipes) in leaflets plate as raw material, the steel plate in the mold or molding machine pressure (volume) into using double-sided submerged arc welding and flaring from production.
Longitudinally Submerged Arc Welding Pipe is subdivided into UOE,RBE,JCOE steel pipe according to its different forming methods.Longitudinal high-requency welded steel pipe has the characteristics of relatively simple process and fast continuous production, andhas wide use in civil construction,petrochemical light industry and other sectors. Mostly used to transport low pressure fluids or madeinto various engineering components and light industrial products.
Features:
● Large diameter steel pipes
● Thick walls
● High-Pressure resistance
● Low-temperature resistance can only use one HS code to declare the pipe fitting. But the straight tubes can not be used with one HS code.
