ERW Carbon Steel Pipe Adopts this Processing Technology
The advantages of post heat treatment after welding process are eliminating residual stress in weld and heat affected zone, grain refinement, small heat affected zone and fast heating speed. It can greatly improve welding speed and welding quality. It can also be used for pickling, shot peening and trimming as billets. At the same time, it can weld alloy steel, high alloy steel and non-ferrous metal pipe. The unit power consumption is greatly reduced, and ERW carbon steel pipe can be produced with a set of welding equipment.
But at the same time, for rigid carbon steel tube unit, the larger the diameter, the more restrictions by the weight of strip and the thickness of raw material wall, the more restrictions on storage equipment by the spiral bending pin. In addition, the ERW carbon steel pipe unit has a high linear speed, and the speed of arc welded pipe is generally 3 M / min, which does not match each other. Therefore, Er carbon steel tube unit needs to make full use of and expand its own advantages to improve product quality and develop new products.
