Pipe flower tubes are made of many small eyes on the basis of steel tubes. Its main function is grouting. Generally speaking, it is widely used in the construction of projects. For steel flower pipe, its grouting effect. This is better.


Steel pipe is a kind of steel, not only for engineering, but also for building materials and machinery. The types and types of steel pipes far exceed those of steel pipes, and their functions are not just steel pipes. The production process is more complex and the use is relatively simple. The required technical performance is high and usually can not be satisfied.


The difference between steel fancy pipe and steel pipe is relatively large, which should be distinguished in use.


Regular specification of steel tube flower tube: 42mm, 48mm, 50mm, 60mm, 89mm, 108mm. It can be customized according to special requirements.


Construction technology of steel pipe flower pipe: a. Measure the pile position, drill holes with drills, and then empty the holes; the Bay will insert the steel tube into the holes, through the pressure drop joint will press the cement slurry into the steel tube; C. Until the pressure occurs, it rises sharply and fills the rock holes, quickly blocking the mud seal.


The application scope of steel pipe is suitable for fragile and fractured rock mass, and the effect of construction and anchorage is good.


Steel pipe has hollow section and is much longer than steel with diameter or circumference. According to the section shape, it can be divided into circular, square, rectangular and special-shaped steel pipes; according to the material, it can be divided into carbon structural steel pipes, low-alloy structural steel pipes, alloy steel pipes and composite steel pipes; according to the purpose, it can be divided into transportation pipes and engineering structures. Thermal equipment, petrochemical industry, mechanical manufacturing, geological drilling, high-pressure equipment steel pipe, etc. According to the production process, it is divided into seamless steel pipe and welded steel pipe, in which seamless steel pipe is divided into hot-rolled and cold-rolled (pulled) two kinds of welded steel pipe into straight welded steel pipe and spiral welded steel pipe. Steel pipe.


Steel pipe is not only used for conveying fluids and powder solids, exchanging heat, manufacturing mechanical parts and containers, but also an economic section steel. Using steel pipe to make building structure grid, pillar and mechanical support can reduce weight, save 20-40% of metal, and realize mechanized construction. Using steel pipe to make highway bridges not only saves steel, simplifies construction, but also greatly reduces the area of protective coating and saves investment and maintenance costs.
