There are two production processes for LSAW pipe: JCOE process and RBE process.
The advantages of JCOE production process are that it can produce more than 30mm thick steel pipe, which is suitable for the production of extra thick wall steel pipe; the disadvantages are low production efficiency (10 pieces / hour) and large investment. It is usually used for the production of straight seam submerged arc steel pipe with diameter range of Φ 508 – Φ 1422mm, wall thickness of 8-40mm and length of 10-12.5m.
RBE production process has the advantages of high production efficiency (15 pieces / hour) and small investment; the disadvantage is that the maximum wall thickness is not more than 30mm. It is usually used for the production of straight seam submerged arc steel pipe with diameter range of Φ 508 – Φ 1422mm, wall thickness of 6-30mm and length of 10-12.5m.
