   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.
