ERW Steel Pipe

Electric Resistance Welded steel pipe (ERW) is a kind of steel pipe produced by welding technology that heats the edges of steel pipes with high frequency current to fuse them together. ERW steel pipe is widely used in the field of oil and gas storage and transportation because of its high production efficiency, relatively low cost and excellent welding quality.

Hebei Huayang Steel Pipe Co., Ltd. currently has 14 advanced high-frequency welded steel pipe production lines, equipped with the latest automation equipment and precise control system. As the source factory, Huayang Steel Pipe provides one-stop procurement service, directly providing customers with high-quality ERW steel pipes, eliminating intermediate links, improving supply chain efficiency and reducing customers' procurement costs.

Standard and steel grade

Every high-frequency welded steel pipe product of Huayang steel pipe has been treated by precise high-frequency welding technology, which has excellent mechanical properties and pressure resistance, smooth surface, accurate size and stable weld quality, and meets API 5L standards.

1. Raw material preparation: select high-quality steel products from steel mills as raw materials, and adjust them flexibly according to different needs of customers.

2. Leveling, cutting and butt welding: Leveling the raw materials, cutting off the head that does not meet the standard, and butt welding the raw materials to prepare for the subsequent molding.

3. Spiral looper: send the butt-welded steel into spiral looper to ensure continuous production.

4. Forming system: The steel is shaped into a tube through a precise forming system.

5. Welding: high-frequency welding is carried out on the formed pipe to form a solid weld.

6. Intermediate frequency annealing: the welded pipe is subjected to intermediate frequency annealing to eliminate the internal stress generated in the welding process.

7. Cooling treatment: cooling treatment is carried out on the pipe to facilitate subsequent processing.

8. Ultrasonic inspection: Ultrasonic inspection technology is used to inspect the weld to ensure the welding quality.

9. Sizing and straightening: sizing and straightening the pipe to ensure that the size and shape of the pipe meet the standards.

10. Cut to length: cut the pipe to length according to the customer's demand.

11. Hydrostatic test: Water with a certain pressure is applied to the inside of the pipe, and the pipe is subjected to hydrostatic test.

12. finished product inspection: conduct final quality inspection on finished pipes to ensure that the products meet the ex-factory standards.

FAQ

 

 

01.What does the acronym ERW stand for?

ERW stands for "Electric Resistance Welding", which means resistance welding. This is a welding technology that heats the edges of steel pipes by high-frequency current to fuse them together, which is used to produce steel pipes.

02.What is the difference between ERW and seamless?

ERW(Electric Resistance Welded) steel pipe is made by heating the edge with high-frequency current and fusing, while seamless steel pipe is made by piercing process or casting method without welding gap.

03.What is the difference between ERW and UXO?

ERW(Electric Resistance Welded) steel pipe is made by heating and fusing the edge of the steel pipe with high frequency current, so it has a weld along the length of the pipe.

UXO(U-Oil) usually refers to a special type of seamless steel pipe used in oil wells, which is designed to withstand high pressure and high temperature conditions in oil wells.
