Cast basalt lined steel pipe ash handling with flange and coupling is composed by lined with cast basalt pipe, outside steel pipe and cement mortar filling between the two layers. It combines the advantages of cast basalt and steel pipe, wear resistance, corrosion resistance, anti-high-pressure, transportation and easy installation. Water transport in plant ash and metal mine tailings pipeline hydraulic conveyance system appling this product can life up to 30 years. Cast basalt lined steel pipe is divided into straight tube, elbow, tee, reducer pipe.

Cast basalt pipe can be divided into straight pipe, elbow, three-way (four-way) pipe and variable diameter pipe, etc.

Comparison of Ceramic lines with few other materials under standard conditions

Basalt is a dark, dense-looking rock, often with small porphyritic crystals, and weathering to a brown colour on exposed surfaces. It is the commonest of all lavas, the basalt flows of the world being estimated to have five times the volume of all other extrusive rocks together. Basalt also forms small intrusions.

Basalt casts are considered the best lining materials for industries dealing with abrasion resistance.

Chemical substance ( weight %) of cast basalt

The excellent performance of cast basalt lined steel pipe is that it sets tenacity of steel pipe, abrasive resistance of cast basalt pipe, concreteness of cement mortar in one.

This greatly improves the products adaptive capacity in complicated operation conditions. At the same time. Cement mortar is selected as the filling material and this can make the inside surface of steel pipe in alkali mediums. So the surface of steel pipe generates purifying films. These films can prevent being rusted.
