Chromium Carbide Overlay Wear Fitting  

Overview:

Wear fittings are 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 wear pipes and fittings are processed and molded by two methods, one is that chromium carbide overlay wear plate is rolled by roller press. the other is that we firsthand weld in the seamless steel pipe.

The performance of wear layer in the pipes is the exactly same with chromium carbide overlay wear plate.

The wear pipes and fitting’connection methods are flange connection and welding  ;

The wear pipes can be processed into elbow、tee branch、Square to round Transitions、frustum、Square tube， etc.

FAQ

Q1: Why are there so many cracks?

A1. Due to the cooling rates of dissimilar metals. Our hard facing plate for coal chute liner is manufactured by welding which results in high temperatures. During the cooling, the plate goes through a stress relieving which is a natural process and does not effect the performance of the plate. The stress relief cracks should be between 3/4" - 2" apart. The cracks can be touched up by our chrome carbide welding rod.

Q2: What is the best method of attachment?

A2. hard facing plate for coal chute liner is usually attached by countersunk bolts, welding studs, perimeter welding, or plug welding. Some methods are better suited than others depending on the specific application. For more detail on each method see the installation section.

Q3: Can hard facing plate for coal chute liner be drilled or machined?

A3. hard facing plate for coal chute liner cannot be machined or drilled. It can however be ground. Mild steel inserts are used to create countersunk or counter bored holes. hard facing plate for coal chute liner can be cut using plasma, Grinding wheel saw, or air-arc gouging.

Q4:MOQ?

A4.Our product has no limit to quantity, it can be ordered according to customer requirement.
