Welded Steel Pipe

Introduction:
The welded steel pipe is known as welded pipe. It is a kind of steel tube welded by the crimp molding of steel plates and strip steels. The production process is simple with high production efficiency. There are various kinds of the products.?

Established in 1998, Cangzhou Leadingfly Steel Pipe Co., Ltd is a professional manufacturer and supplier of welded steel pipe in China. ?Our welded steel pipes have obtained the certification of American petroleum institute and the international security organization.

Application:
General welded pipe is applied to convey low-pressure fluid. We can manufacture it by using the steels of Q195A, Q215A, and Q235A types, and we can also use other mild steels that are easily welded. To assure quality, there are hydrostatic test, bending test, and crushed test. Besides, there are also some requirements of the surface quality, and the usual delivery length is 4-10m, often required sizing delivery. The specifications of welded pipes are showed by the Nominal diameter (millimeter or feet) which is different from the actual size. It is divided into common steel and heavy steel according to the specification of wall thickness. In addition, on the basis of pipe end, it can be divided into pipes that are with end thread or without taking thread.

Subclass products:
ERW straight seam steel pipe, LSAW steel pipe, SSAW steel pipe, double submerged arc butt welding steel pipe, square steel pipe, rectangular steel pipe, and galvanized steel pipe.

Feature:
In the case of assuring quality and providing a reasonable price, we will accelerate the delivery cycle according to the number and specifications of the contract.

Apart from welded steel pipe, we also provide clients throughout the world with ERW steel pipe, square steel pipe , seamless steel pipe, galvanized steel pipe, custom steel pipe, anti-corrosion steel pipe, pipe fittings, etc. With high quality and competitive pricing, our welded steel pipes have been well received by customers from Europe, America, Middle East, Africa, Southeast Asia, Australia, New Zealand, Korea, and many other countries and regions.
