Product Description


Chromium Carbide Overlay Wear Resistant Mud Slurry Sand Gas Oil Dredging Pipe
Hardfacing/Cladding/Clad Chromium Carbide Overlay Wear Resistant Mud Slurry Sand Gas Oil Dredging Pipe

HART Hardfacing Overlay Pipe is manufactured by depositing chromium-rich, abrasion-resistant materials on the mild steel pipe, using a traditional arc welding process. The Pipe is available with double or multiple overlay passes. And it can be fabricated as square-to-round transitions, elbows, T or Y- shaped.

The hardfacing overlay pipe is designed with extreme wear capabilities for working in many applications: mining, cement, oil sands, dredging, recycling and steel production industries.

8. Microstructure: 
Composed of a high proportion of extremely hard primary M7C3 chromium rich carbides dispersed in a ductile eutectic austenite matrix. 
Maintains 30% to 50% of primary carbides to provide a good wear resistance and homogenous bonding.

11. Service 
SERVICE DESCRIPTION
Cutting 1. Can be cut by plasma, laser, water jet, arc gouge, and abrasive saw cutting; 
2. Cannot be cut by oxy-fuel. 
Welding
1. Use 480 MPa (70 ksi) or 560 MPa (80 ksi) consumable to join base metal; 
2. After welding, joint should be capped by overlay for wear protection. 
Machining
1. Not machinable by conventional methods; 
2. Can be finished by grinding only; 
3. Countersunk holes can be precisely produced by EDM (Electrical Discharge Machining). 
Forming
1. Commonly formed with overlay to the inside; 
2. For pipes with diameters smaller than 0.6m (24"), hardfacing pipe recommended instead of pipes fabricated from hardfacing plate. 
Drilling
1. When drilling, the distance between two holes should be at least 15mm (5/8''); Otherwise, the partition may not be strong enough and can crack; 
2. The minimum diameter of holes should be equal to the thickness of the plates. For thicker plates with a total thickness over 20mm (3/4''), the minimum diameter should be 1.5 times the thickness of the plate. 


12. Testing and quality control
We documented how the product properties are tested in order to make sure the overlay plates fulfil the specified product properties. Including documentation on 3D party's quality system if calibration and testing is performed by 3D party.
