   Hot rolled carbon welded steel pipe

 

RK-200 abrasion resistant pipe not only has good wearable performance, temperature resistant, impact resistant but also has good elasticity. The pipe has very good weldability and it is easy to install; particularly suitable for any use under extreme temperature. For instance, it can be applied to transport hard materials in electrical, metallurgy, coal and cement industry, etc. In comparison to the regular pipe, our product is more wearable, more durable and more economic.

 

 

 

The hardness of wear resistant layer is up to HRC 63 degrees, which is equivalent to the tungsten-cobalt. The wearability of it is 20 times better than carbon steel pipe and it is much superior to corundum grinding wheel. Presently, dozens of thermal power plants demonstrated that dual metal wear resistant steel pipe has high wearability and strong resistance to fluid impact. In Elbow wears fastest in primary duct, the wear resistance elbow is 5 times better than casted thick wall wear resistant elbow. In practice, composite layer of wear resistant steel pipe has no significant wear or shed after 2 years. In the same specifications and unit length of a pipeline, the weight of dual metal wear resistant steel pipe is only 1/2 as heavy as casted wear resistant steel and 2/5 of casted stone pipe or lanthanon wear resistant steel pipe. In general, it makes per meter project cost lower, cost reduced ranging from 30% to 40%. It can be applied under the circumstance of erosion and high temperature and the price of it is only a fraction of stainless steel pipe and nickel titanium pipe
