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.

Clamp-type flexible pipe joints are used for connecting steel pipes. The KRH and KRJ series forged clamp-type flexible pipe joints are patented products of our company. They have a unique air-sealed principle, a unique C-type rubber sealing ring, and a unique connection method, giving them a triple sealing effect:
a. First Seal
The rubber sealing ring itself has self-tightening properties and relies on its own elasticity to press tightly against the pipe;
b. Second Seal
After tightening the bolts on the outer pipe clamp, the rubber air seal ring will be further compressed;
c. Third Seal
When there is pressure in the pipeline, the pressure will apply pressure to the C-shaped lip of the sealing ring from the inner cavity, making the rubber sealing ring press more tightly against the pipe. The higher the pressure, the better the air sealing performance.
Realization of the Angle of the Clamp-type Flexible Pipe Joint:
Since the outer metal pipe clamp of the clamp-type flexible pipe joint does not tightly adhere to the pipe and has a reasonable gap with the pipe, the pipe can be rotated to a certain angle.
Realization of Expansion and Contraction of the Clamp-type Flexible Pipe Joint:
The structure of the clamp-type flexible pipe joint allows each pipe joint to achieve a certain degree of expansion and contraction. The amount of expansion and contraction can be adjusted according to specific needs and different models.
Clamp-type flexible pipe joints are widely used in power plant ash handling systems, mine tailings systems, and wastewater treatment, chemical, and papermaking industries. 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 overall cost-effectiveness than flange connections.
