API LSAW Steel Line Pipe
API 5L X70 Natural Gas Line Pipe
Description
LSAW steel pipe is a technical term for Longitudinally Submerged
Arc Welding steel pipe. LSAW steel pipe is created by using a
medium-thickness plate as the raw material, pressing the steel
plate into a tube blank in a mold or forming machine, applying the
double-sided submerged arc welding method, and also enlarging the
diameter.
There is a wide range of specifications of this kind of product,
and the weld-seam has good uniformity, compactness, plasticity, and
toughness. It has the strong points of large pipe diameter, thick
pipe wall. It also has the advantages of corrosion resistance,
high-pressure resistance, and low-temperature resistance.
Manufacturing Types
Seamless: Covers hot rolled seamless and cold drawn seamless.
ERW: Electric Resistance Welded
LSAW: Longitudinal Sub-merged Arc Welding
SSAW: Spiral Sub-merged Arc Welding
HSAW / DSAW: Same with SSAW for spiral welded pipe
