LSAW Pipe (Longitudinal Submerged Arc-Welded Pipe) is formed by JCOE with one straight welded seam, taking plate as raw material, using double-sided submerged arc welding and flaring from production. With a wide range of finished product specifications, weld toughness, ductility, uniformity and dense, with large diameter, wall thickness, high pressure resistance, low-temperature corrosion resistance, etc.
Out diameter usually from 323mm to 1420mm. When the outer diameter is above 914.4mm it’s allowed two straight welded seams.
Usage: Long distance transportation for oil, gas, liquid, coal gas, etc. inshore and offshore, also used as construction pipes, offshore platform, power station, petrochemical and civil construction, etc.
Outer Diameter: 219mm-1820mm (8’’ ~70’’)
Wall Thickness: 5.0mm-50mm
Length: 5.8mtr-18mtr
End: square ends (straight cut, saw cut, and torch cut). or beveled for welding, beveled,
Surface: Lightly oiled, Black, Bare, Varnish coating/Anti rust oil, Protective Coatings
MATERIAL: CS, LTCS
Q235, Q345, ASTM A25, API 5L GR.B, X42, X46, X52, X60, X70, etc.
STANDARD: API 5L, ASTM A252, ASTM A672, ISO3183, GB/T3091, GB/T9711, etc.
