Introduction
Longitudinally Submerged Arc Welding Pipe is subdivided into UOE, RBE, JCOE
steel pipe according to its different forming methods. Longitudinal
high-frequency welded steel pipe has the characteristics of relatively simple
process and fast continuous production, and has wide use in civil
construction,petrochemical, light industry and other sectors. Mostly used to
transport low pressure fluids or made into various engineering components and
light industrial products.
When compared UOE vs JCOE pipes, LSAW steel pipe manufacturers in China can
produce more sizes as:
· Outside Diameter:219mm-1625mm;
· Wall Thickness: 6.35 mm – 60 mm;
· Length: 2 m – 18 m
From this, we can see that the LSAW pipe having superiority. We, Winsteel
offers LSAW pipe with high quality, competitive prices, and best service.
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

How to Use LSAW Pipe for Pipelines
1. According to the specification of pipe API 5L Spec, we take testing for
the basic metal and welding metal. Meanwhile, we have other Specifications. Such
as DIN, EN, ASTM, and GOST. Also, the LSAW steel pipe can welded with flanges.
Welding lifting eyes and other parts according to clients’ requirements.
2. It also can used as pipe boots or pile boots which acted as protecting a
section.
3. Except used as pipe boots. The LSAW steel pipe is also used for
transporting fluids like water, oil & gas. As well as used for offshore
projects and underground constructions. These products are producing in China.
And exported to other countries. For example Australia, Canada, South American,
Europe, Malaysia, India, Pakistan, Africa, etc.
