Pipe end: plain end (PE), beveled end (BE), threaded end (THRD), grooved, flanged, etc.LSAW steel pipe:
Steel pipe made by longitudinal submerged are welding-the production process begins with a plate which is formed into a pipe by bending and welding longitudinally, generally using JCOE (J-ing, C-ing, O-ing, expanding) or UOF process.
LSAW pipe is a high-strength, large-diameter steel pipe, generally designed for high pressure, high durability, high toughness applications, used for oil/gas/water/steam transportation, for steel structure, critical infrastructure, etc.
Senhai pipeline possesses four full sets of JCO forming lines (3000t, 8000t, 10000t and 12000t), one set of JCOE forming machine imported from Germany, producing LSAW pipes with size OD325mm to 2020mm with one longitudinal weld seam or double seamed, and hot shrinking hot rolled steel pipe production line changing the big-size pipe to required non-standard sizes.LSAW pipe manufacturing process flow chart:
