The excellent performance of cast basalt lined steel pipe tee is that it sets tenacity of steel pipe abrasive resistance of cast basalt pipe concreteness of commemorator one. 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.
Cast basalt pipe can be divided into straight pipe, elbow, three-way (four-way) pipe and variable diameter pipe, etc.
