Wear Resistant Alloy Tube
Chromium Carbide Overlay (CCO) Steel Pipe is chromium carbide overlay on the inside diameter of the standard wall pipe. Wear resistant chrome pipe is composed of the wear base material and the wear layer, the wear layer is generally accounts for 1/3or 2/3 of total thickness; The wear layer and the base material is combined through metallurgy, so that the wear layer can’t fall off, and can bear stronger impact.
The features of chrome carbide overlay steel pipe:
1-preferable wearlessness
2-superior heat resistant performance
3-Excellent machining performance
4-Superior cost performance effect
Chemical composition:
| Cr | C | Si | Mn | others | Hardness |
| 24-30% | 4%-5% | 0.5%-1.5% | 0.5%-2.5% | Less than 2% | 58-62HRC |
Hardfacing layer information:
| Hardness | HARDNESS TOLERANCES | Thickness tolerances | Weld pool | Welding direction |
| 58-62HRC | -0/+1,5 HRC | -0/+1 mm | 2mm | Lengthways of the plate |
The advantage of CCO pipe:
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
