The structural characteristics of cast basalt lined pipe

Cast basalt lined pipe is cylindrical, and its pipe material is composed of the outer wall of the cylinder and the inner wall of the cylinder. The thickness of the cast stone layer is 10-15mm. Its characteristics: thin pipe wall, light weight, low temperature melting, rapid crystallization, yield of more than 85%, strong overall performance of the mesh cast stone layer, not only has the advantages of wear resistance and corrosion resistance of cast stone pipe, but also has the advantages of other pipes. The characteristics of the installation are the formation of steel pipes, steel mesh pouring basalt cast stone layers, and trinity of new prestressed composite cast stone pipes. It is widely used in wear-resistant and anti-corrosion parts of electric power, chemical industry, metallurgy, mining and building materials industries.​​

The prestressed concrete pipe on the outer layer of the cast basalt lined pipe is composed of the cast stone pipe on the inner layer and the filling layer in the middle. The gap between the filling layer is small, which is mainly designed to facilitate the assembly of the outer layer pipe and the inner layer pipe. ; The filling layer can be made of fly ash or cement mortar; this kind of composite pipe has the characteristics of low cost and long service life without corrosion.​​

The cast basalt lined pipe is made of seamless steel pipe and basalt stone, and a new centrifugal composite process is applied. Strength, wear resistance and corrosion resistance of cast stone pipe; connection methods include flange connection, flexible pipe joint connection, sleeve type flexible pipe joint connection, butt welding connection; single length: can be any multiple of 1.5 Length, commonly used sizes are 3m, 6m, 9m, 12m, etc.; prestressed composite cast stone pipe is divided into straight pipe, elbow, tee (cross).

The cast basalt lined pipe has good overall performance, high bearing strength, wear resistance, does not fall off, and is not easy to scale. And the transportation, installation and construction are simple and convenient. It is an ideal pipe for long-distance pneumatic and hydraulic transportation of powder and slurry in electric power, mining, metallurgy, building materials and other industries.
