We are specialized in large-diameter thick-wall straight-seam longitudinally submerged arc welded carbon steel pipes (lsaw pipes), and they are mainly used for:
1) petrochemicals: for the crude oil, petrochemical raw material & products transmission and the pipelines in the oil fields.
2) natural gas: onshore & offshore long pipeline; gas station transportation; pipelines in the gas fields and cities.
3) structural pipe: piles of wharf; structural pipes for bridges and tall buildings; offshore flat.
4) others: water transportation, offshore suction & drain pipeline product name: lsaw steel pipes
Forming mode: jcoe
Materials: api 5l and other materials with requirements from our customers; grade: x80 or/and lower, diameter: ª¦406-1524mm, wall thickness: 6-40mm, unit length: 8-12m
