About UsSpecializing in the production and sales of wear-resistant materials such as cast basalt products, the company has obtained over 20 invention patents and utility model patents, and was awarded the "Shandong Star Enterprise of China Patent" title. The company has a history of over 20 years, and currently owns a single basalt cast basalt production line with a production capacity of 15000 tons/year, and mechanical processing equipment with an annual output of 5000 wear-resistant valves and 20000 clamp-type flexible pipe joints.

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.
