Hollow Hection Of The Fluid Tube

 

Fluid pipe is a hollow cross-section. From start to finish no welds. Steel hollow section. Many pipe oil, gas, gas, water pipes used for the conveyance of fluid conveyance and some solid materials, and the like. And other steel and solid steel bar match. Torsional strength in bending phase together. Weight. It is an economic cross-section steel. Widely used in the production planning parts and mechanical parts. Such as drill pipe, automotive drive shafts, bicycle frames and roof construction using steel scaffolding. Production of parts with steel ring. May be advanced material utilization. Simplified production process. Saving material and machining time. Such as bearing rings, jack sets. It was already widely used to make steel production. Pipe is still a variety of conventional weapons indispensable material. Gun barrels would have to steel to produce. By cross-section shape of the pipe is not the same can be divided into tube and shaped tubes. Because in the perimeter of equal conditions. The maximum area of ​​a circle. Circular tube can carry more fluid. In addition, the circular cross section to withstand internal or external radial pressure. The force is uniform. Thus, the vast majority of pipe is pipe.

Production Production Methods:

1. General boiler tubes using a temperature below 450 ℃. Domestic primary tube 10, on the 20th of carbon structural steel hot-rolled or cold-drawn pipe tube production.

2. The high-pressure boiler tubes are often in high temperature high pressure conditions, the use of paper. The role of high temperature gas and steam pipes under. Oxidation and corrosion will occur. We need durable steel with high strength. High resistance to oxidation corrosion function. And have excellent organizational stability.

Hollow Section Of The Fluid Tube Use:

1. General boiler tube is mainly used to produce water wall tube, boiling water pipe, superheated steam pipe, superheated steam locomotive boiler tubes, and large and small smoke pipe and brick arch tubes.

2. The high-pressure boiler tube is mainly used to produce high pressure and ultra-high pressure boiler superheater tubes, reheater tubes, windpipe, the main steam pipe.

However, the tube also has some limitations. Under conditions such as by plane bending. Tube as good as square, rectangular tube large flexural strength. Some farm machinery skeleton, steel and wood furniture on the popular square, rectangular tube.
