Cast Basalt Composite Elbow

Product Details

Product Description

Product Description
Cast basalt composite elbows are used too many industrial areas where the abrasive, chemical and hot materials transported and which are commonly lined steel elbows. Cast basalt composite elbow is composed of steel pipe tee, cast basalt pipe and cement mortar concrete. 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.

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.

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.
