Question:

Is the same specification seamless steel pipe more expensive than welded pipe?

Is the same specification seamless steel pipe more expensive than welded pipe?

Answer:

You need to see this in the interval that diameter, such as seamless pipe and welded steel tube 530*20 mm compared to 5450 yuan per ton, seamless pipe, welded steel pipe, which is 4550 yuan, small diameter 10*2 mm, seamless pipe will require far 10000 per ton, just need more than 6000
Welded steel pipe refers to the use of steel or steel plate bending deformation into a round, square and other shapes after welding into the surface of the joint of the steel pipe. The blank used in welded steel pipe is steel or strip steel.
Seamless steel pipe having a hollow cross section, used as a conduit for conveying fluids, such as pipelines for transporting petroleum, natural gas, gas, water, and certain solid materials.
Specifications of the same kind of seamless steel pipe than welded pipe prices are generally about 30% high, large diameter difference is greater.
