Product Introduction

LSAW and SSAW are variants of SAW (submerged arc welded) pipes.
The difference between them is the way they are welded.
In LSAW pipes, the welding is longitudinal, which means that steel (hot rolled coil plate) is rolled into a pipe and the seam is welded longitudinally.
In the SSAW type, steel coils are welded spirally, like a helix, so that the coil (strip) assumes the shape of a pipe.
SAW pipes are used mainly in oil and gas transportation.
On the other hand, seamless (non-welded) pipes are mainly application in oil and gas exploration projects.
An LSAW pipe (“submerged arc welding”) is manufactured by cutting, bending, and welding steel plates (JCOE process).
The two main types of LSAW pipes are the longitudinal (with a single or double straight seam weld, DSAW) and the spiral type (called, HSAW, SSAW or SAWL pipe).

Application:

Due to the high hardness, strength, wear resistance, and anti-corrosion features. Carbon steel welded pipes are commonly used in the following industries and applications:
1. Oil & Gas Applications
2. Boilers
3. Condenser Tubes
4. High Pressure Applications
5. Chemical Industry
6. Water Transmission
7. Structural Applications
8. Mechanical Components
