Wearback cast basalt lined bends with wearback arrangement offers better life as compared to normal wearcoat / cast basalt lined bends in pneumatic conveying system for fly ash, cement, coal
etc where abrasion is more. Wearback cast basalt lined bends are composed of steel pipe tee, cast basalt pipe and cement mortar concrete. Wearback cast basalt lined bends are used too many industrial
areas where the abrasive, chemical and hot materials transported and which are commonly lined steel elbows. 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.
