Hard Facing Protection Sleeve Liner

Hard Facing Protection Sleeve Liner

Hard facing protection sleeve liners are manufactured by welding one or multiple wear resistant layers on a medium or low carbon steel base plate. The overlay alloy has a high amount of chromium carbide hard particles. This chemical proportion results i a large amount of Cr7C3 chrome carbide hard particles. The hardness is HRC 58~65 ( HV650~860) and depends on the overlay's thickness and chemical composition. The micro-hardness (up to HV1800) of these particles throughout the layer will guarantee a super wear resistant surface.
We can customize the plates in different sizes and thickness based on customer's drawings. We can also cutting, bending and welding the wear plate into specific shapes and parts, as well as keep the good flatness.

hard facing protection sleeve liners are subject to abrasion, erosion, cavitation and sliding wear in service. Abrasion and erosion results from abrasive particles in the medium being pumped, but even in the absence of any abrasive particles sliding wear can occur due to unintentional contact between rotating and stationery components. Moreover these wear rates in pumps are often unexpectedly high because of the synergistic relationship between wear and corrosion; even a mildly corrosive process media can significantly increase wear rates. This is often increased even more by the high flow velocities that can be found in some high-energy pumps.

As the pump components in the flow path wear, efficiency critical sealing clearances increase and vane angles change, resulting in a decrease in pump efficiency over time. hard facing protection sleeve liner is also common in other areas of the pump such as product lubricated bearings and shaft sleeves, often resulting in increased vibration or leakage over time. Wear therefore reduces the service life of the pump and increases the life cycle cost significantly. There are numerous strategies to reduce the impact of wear on pump components such as specialized pump design and the use of sophisticated materials but surface coatings are some of the most successful and cost-effective tools for managing wear.

FAQ

Q1: Why are there so many cracks?
A1. Due to the cooling rates of dissimilar metals, HARD PLATEhardfacing alloy plate alloy steel wear sheets boards on sale is manufactured using a welded process. This process results in high temperatures. During the cooling process, the plate goes through a stress relieving process. This is a natural process and does not effect the performance of the plate. The stress relief cracks should be between 3/4" - 2" apart. There are typically two methods used in situations when the hardfacing side is required to be on the outside of a tight radius resulting in cracks wider than desired. the cracks can be touched up using an appropriate hardfacing wire or electrode.

Q2: What is the best method of attachment?
A2. HARD PLATE hardfacing alloy plate alloy steel wear sheets boards on sale is usually attached by countersunk bolts, weld 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 this plate be drilled or machined?
A3. No. HARD PLATE hardfacing alloy plate alloy steel wear sheets boards on sale can not be machined or drilled. It can however be ground. Mild steel inserts are used to create countersunk or counter bored holes. HARD PLATE 6+3/8+3/8+5 wear resistant steel plate 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.

Q5:What’s the service life compare with Hardox series?

A5.Generally speaking, our bimetallic overlay wear plate is 4.5~8 times than Hardox series in service life.
