Cast basalt line steel straight pipe 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.

This greatly improves the products adaptive capacity of 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.

Main specification of cast basalt lined steel pipe

Other specifications of cast steel pipe lined with basalt can be manufactured according to customer technical requirements. Suitable for large-diameter basalt lining steel pipes with a nominal diameter greater than 800mm. Generally, according to the running status of the pipeline, different cement is used to fix the basalt brick inside the finished steel pipe to complete the basalt lining steel pipe. Its advantages are good wear resistance, wide range of use, basically not limited by the size of the pipeline and low cost of pipeline installation.

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

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.
