Welded steel pipe like ERW steel pipe, is now widely used among various industries. And the types of weld pressure rolls applied the pressure require for the weld are as varied as the welding units used to supply the heat.
Then, how many roll units are needed in steel pipe production?
According to different size and shape of the product being welded, the number of rolls in the weld squeeze box is proportionate. There are no hard and fast rules; however, common guidelines for round tube or pipe size ranges are as follows:
3/8 to 2 in. uses two-roll units.
1/2 to 3 1/2 in. uses three-roll units.
2 to 10 in. uses four-roll units.
Larger than 10 in. uses five or more rolls.
Now with the wide demands coming from customers, there are square, rectangular, hexagonal which are welded in the finished shape rather than being reshaped after being welded round.
