1.the difference between raw material and production capacityERW steel pipe raw material is hot rolled steel coils, UOE pipe raw material is hot rolled steel plate. So the ERW steel tube can realize continuous assembly line work, high production efficiency, production cost is low; And UOE pipe made with steel plate processing, unable to realize continuous assembly line, the production efficiency is low, the production cost is high. ERW steel pipe limited by the thickness of the steel coil, general can produce the biggest thickness is 25 mm, it can produce the biggest diameter is 660 mm; And can produce the maximum thickness of UOE pipe to 40 mm, it can produce the largest diameter is only restricted by steel plate width, now can produce maximum diameter is 1422 mm.2.the welding processERW steel pipe welding does not need to add solder wire; UOE pipe is added welding wire.3. difference in appearanceERW steel tube to remove both internal and external welding seam, so good for anti-corrosion; UOE pipe weld more than high, inside and outside wall against corrosion.4.the purchase cost and the difficulty ERW steel pipe procurement costs low, the cost of UOE pipe is very high, generally spread of 15% to 15%. Domestic production of UOE pipe manufacturer is less, purchasing difficulty is high. When diameter < Φ 406 mm, the procurement cost difference is bigger. ERW steel pipe manufacturer is more, low purchasing difficulty, when the diameter of < Φ 406 mm, will greatly reduce the purchasing cost. 5.the application of distinction ERW steel tube is mainly used in natural gas, refined oil, crude oil, such as pulp land long distance pipeline.UOE pipe is mainly used in high voltage long distance pipeline, cold area at the bottom of the two, three, four, land area.
