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.
How to correctly use wear-resistant cast basalt valves, and their maintenance and repair?
We know that most wear-resistant cast basalt valves require very little maintenance, meaning that most wear-resistant cast basalt valves do not need frequent repairs.
We know that most wear-resistant cast stone valves require very little maintenance, meaning that most wear-resistant cast stone valves do not need frequent repairs. However, sometimes even a small problem like a simple stem leak can become a big problem due to negligence. Even worse, some reckless operators fail to close the cast stone valve according to technical specifications, leading to stem bending or serious damage to the closing device. Such situations occur frequently.
The threaded connection between the stem nut and the stem should be lubricated regularly with lubricating oil. This not only reduces friction between them but also extends their service life. This is also a very important protective measure. If a worn stem nut is still in use, it may break, and the entire axial force of the stem will not be supported, causing the wear-resistant valve to fail. The bending of the stem may be caused by the operator excessively turning the handwheel after closing the wear-resistant cast stone valve.
