Chinese standard steel pipe Q235 / Q345 coated high quality low consumables cco surfacing pipe and fittings are made by welding one or more layers of wear resistant coating on medium and low carbon steel substrates. The cover alloy has a large amount of hard chromium carbide particles. These particles are evenly distributed throughout the coating to form a strong microstructure. The hardness is between 58 and 62 HRC, which is determined by the thickness of the cover layer.
The main components of the pipe are C (%): 3.0 to 5.0 and Cr (%): 25 to 40. This chemical ratio results in a large amount of Cr7C3 chromium carbide hard particles. The microhardness of these particles throughout the layer (up to HV1800) will ensure an ultra-abrasive surface.
The cover layer and the substrate layer are joined by metallurgy. The overlay will penetrate the substrate by approximately 0.8 to 1.8 mm and reach 350 Mpa in our tests.
1-In the inner or external wall of general steel pipe, with wear resistant pipe welding machine directly clad wear resistant layer of high carbon high chromium. Compared with manual welding,automatic welding will not have wear resisting layer off phenomenon, improve the service life of wear resistant pipe.
2-Can be cut,formed and welded
3-Cost effective
4-Increased wear life of piping systems
5-Minimise downtime
6-Reduce maintenance and operational costs
7-Weld overlay can be applied to two sides for added strength and durability
8-increase production
