Distinguish between ERW pipe and spiral welded pipe

    We would like to say that the building’s exterior is beautiful when we see one. Of course, the exterior good look is also concluding the shape of various steel pipes like ERW steel pipe, spiral welded pipe which are used for water, oil and gas transportation.

    No matter which kind of steel pipe you choose for your engineering project. The poor-quality steel pipes would be ousted from the group. So how could we figure out our demands for exact engineering project or estimate houses? Comparison would be one of the top choice for us.

    Straight seam high frequency welded pipe, made by welding and induction, is classified different exposure to welding in two forms, hot and cold rolled. For hot rolled coils as raw materials, with other processes like continuous molding, welding, heat treatment, sizing, straightening, there is no doubt that ERW steel pipe is used for low pressure liquid delivery, such as water, gas, and oil.

    For spiral welded pipe, with the characters of short, high dimensional accuracy, uniform thickness, surface quality, there is no doubt that it can hold on higher pressure than ERW steel pipe. Thus, we can choose the spiral welded pipe for the high pressure engineering project rather than the ERW steel pipe when we meet this situation.
