Steel - High-chromium-nickel alloy composite pipe complex by the outer wall and the inner liner is made of 5-12mm thick wall seamless steel pipe, lined 6-25mm thick high-chromium-nickel alloy, centrifugal composite made of straight pipe, pipe vacuum negative forged, the product takes full advantage of the large seamless steel pipe bearing capacity, high hardness and good welding performance of high chromium-nickel alloy (HRC55 - 60), is an ideal abrasion pipeline.

Wear-resistant pipes including wear elbow, straight pipe, structural tee, head size, radius sections, adjustable tube, mainly for pneumatic pumping slurry pipelines and other materials. Because the transmission medium with high hardness, flow speed, flow rate, etc., can effectively reduce the transmission medium to produce long-lasting impact on the wall, wear, corrosion fatigue resulting in the duct velocity gradually being worn.
