Cast BasaltCast basalt products include cast basalt pipes, cast basalt tiles, cast basalt powder, cast basalt lined steel pipes, etc., mainly used in industries such as electric power, metallurgy, mining, coal, building materials, and chemical.
-
ValveCast basalt ball valves are durable, have a long service life, low fluid resistance, reliable sealing, wear and corrosion resistance, and the sealing surfaces of the ball and valve seat are always isolated from the medium during the fully open and fully closed processes of the valve, so that the medium passing through the valve at high speed will not erode the sealing surface.
-
Pipe FittingClamp-type flexible pipe joints are used to connect pipes. KRH and KRJ series rolled clamp-type flexible pipe joints are patented products of our factory. They can effectively compensate for thermal expansion and contraction caused by temperature changes in the pipeline system, and can also compensate for angular changes caused by pipeline foundation settlement. They are high-pressure resistant, easy to install, and have a much better price-performance ratio than flange connections.
