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.
-
BLOGSince its establishment in 1986, the company has cumulatively produced: over 1600 kilometers of cast basalt lined steel pipes; over 260000 sets of flexible pipe joints; over 18000 valves of various types. Its products cover all provinces nationwide and are exported to countries such as South Korea, the United States, Serbia, South Africa, Zimbabwe, Japan, India, Vietnam, Russia, Poland, Ukraine, Kazakhstan, and Australia.

Cast stone composite pipes are composed of a cast stone inner liner, a steel outer pipe, and a cement mortar filling layer between them. They combine the wear and corrosion resistance of cast stone pipes with the high strength and easy connection of steel pipes. They are wear-resistant, corrosion-resistant, high-pressure resistant, and easy to install and transport. In power plant hydraulic conveying ash and slag, and metallurgical and mining hydraulic conveying tailings and other materials pipeline systems, the service life can reach more than 30 years. Our cast stone composite pipes are produced using horizontal assembly and vertical filling methods, with good concentricity of the inner and outer pipes and a dense filling layer.
Cast stone composite pipes are available in straight pipes, bends, tees, reducers, etc. They can be connected using flexible pipe joints, flanges, welding, etc., and are currently our company's largest export product.
In 1990, the Northeast Electric Power Design Institute and the East China Electric Power Design Institute conducted a survey on the applicability and effectiveness of cast stone composite pipes for several large power plants built under the circumstances at that time. The survey scope was wide and representative, covering more than 30 power plants, including Taizhou Power Plant in Zhejiang, Luohe Power Plant in Anhui, Wujing Power Plant, Taizhou Power Plant, Huangdao Power Plant, Pingwei Power Plant, Ligan Power Plant, and Beilun Power Plant. The application conditions varied, and the product specifications also differed, but the application results were all good. The survey results showed that cast stone composite pipes are unmatched by other materials in power plants for conveying abrasive materials such as ash and slag, providing strong evidence for the widespread application of cast stone composite pipes in power plants.
When designing cast stone composite pipes, only the stiffness and strength of the outer steel pipe need to be considered according to industrial and mining standards. Tested by the Hydraulics Institute of the China Institute of Water Resources and Hydropower Research, its hydraulic smooth flow resistance coefficient is 0.0165-0.0183, and the equivalent roughness is 0.085mm, which is the best among similar pipes.
Our company can provide users with cast stone composite pipes of all specifications with a nominal diameter of φ40mm and above. Products with DN≤900mm use cast stone pipe composite, and products with DN﹥900mm use equal-diameter arc-shaped cast stone plate composite.
