Jacketed cast basalt pipe

The jacketed cast basalt pipe is composed of inner and outer metal sleeves connected by flanges or annular plates, with a cast basalt layer of more than 30mm in the middle. The gate is opened on the outer metal pipe, and the magma is poured into the inner and outer interlayer of the preheated clamp pipe. After crystallization, water withdrawal and aging treatment, the pouring riser is closed, and the outer surface can be delivered to the customer for use.
