Galvanized steel pipe—widely used in all fields

Galvanized steel pipe is usually divided into cold galvanized steel pipe and hot dipped galvanized steel pipe in the current steel pipe market. However, cold galvanized steel pipe is limited to some extent and hot galvanizing steel pipe is widely advocated in all walks of life especially in construction fields. Since 2000, China began to ban the application of galvanized steel pipe as water pipeline. While, hot dipped galvanized steel pipe are widely used in fire fighting, power companies.

There are many types of welded steel pipe as well as pipe application. According to the shape of the welding, the pipe can be classified into straight seam welded steel pipe and spiral welded pipe. For straight seam welded steel pipe, its production process is simple and the production efficiency is relatively high, so the production cost is also quite low, which lead to a rapid development. The strength hardness of the spiral welded pipe is higher than that of straight seam welded pipe. Therefore, we can use narrow raw materials to produce welded steel pipe with relatively large pipe diameter. At the same time, we can also use the width of the large raw materials for production to make welding pipe with different pipe diameters. In addition, the length of the welded can be increased by 30% to 100%. but the production speed is slow. Small diameter is usually suitable for straight welding pipe and the large diameter is used for spiral welded pipe. What is the difference between pipe and tube in foreign trade English? They are technically different, but the emphasis is on the size of the tube, which is under 15mm in diameter while the welded steel pipe is more than 15mm.

Square pipe is a type of tube and many kinds of materials can be used to drill into a square pipe. Its specification takes 10*10*0.8-1.5 to 500*500*10-25. the square pipe can be divided into structure, decoration, construction and machinery according to different application. After a series of processing such as flatting, coil bending, welding, square steel pipe can be formed into round steel pipe. Hot galvanizing steel pipe has the advantage of uniform coating, strong adhesion and long service life. Cold galvanized steel pipe is actually electrogalvanizing and the galvanizing quantity is very small. Its own corrosion resistance is different than that of hot galvanizing tube. In order to guarantee pipe quality, most steel pipe manufacturers will give up electric galvanized.
