Features and uses of spiral tube

Spiral pipe is an industrial pipe, also known as spiral steel pipe or spiral welded pipe. It is made by rolling a steel strip of low carbon structural steel or low alloy structural steel into a tube blank at a certain spiral angle, and then welding the seam of the tube . Let me introduce you to the characteristics and uses of spiral tubes.

The characteristics of spiral tube are as follows:

The production process of quilted welded pipe is simple, the production efficiency is high, the cost is low, and the development is fast. The strength of spiral welded pipes is generally higher than that of straight seam welded pipes. Welded pipes with larger diameters can be produced from narrower billets. Welded pipes with different diameters can also be produced with billets of the same width. However, compared with the straight seam pipe of the same length, the weld seam length is increased by 30 to 100%, and the production speed is lower. Therefore, the smaller-diameter welded pipes are mostly straight seam welded, and the large-diameter welded pipes are mostly spiral welded.

The main purpose of spiral tube:

Spiral pipe is mainly used in water engineering, petrochemical industry, chemical industry, power industry, agricultural irrigation, and urban construction. It is one of the twenty key products developed in China.

For liquid transportation: water supply, drainage, sewage treatment engineering, mud transportation, marine water transportation.

For gas transportation: coal gas, steam, liquefied petroleum gas.

Structural use: used as pile pipe, bridge; pier, road, building structure pipe, marine pile pipe, etc.

The spiral tube is relatively easy to corrode, so it is necessary to perform rust removal treatment frequently to ensure the normal use of the spiral tube.
