SLS600庐 Induction Hardened Wear Pipe

SLS 600^庐 Induction Wear Pipe

Clifton Steel鈥檚 SLS600^庐 induction hardened wear pipe is engineered 亚博系列全平台入口 maximum life in highly abrasive applications, with a special chemistry and core hardened pipe.

Induction hardened pipe is achieved by a unique heating/quenching process. This process alters the microstructure of the steel through the pipe wall, resulting in an inner surface hardness of 600 BHN. While the inner surface provides exceptional abrasion resistance, the outer surface cools slower, remaining more ductile, with a hardness of 250 BHN. The unique process allows the pipe to accommodate service and welding stresses.

This wear pipe is a highly economical solution to many of the abrasive wear problems found with carbon steel pipe. It is also a much more user and maintenance friendly option to replace the heavy, brittle cast piping often used to combat abrasion.

Fabrication

We recommend the use of Clifton Steel鈥檚 fabrication services to eliminate processing and fabrication errors.听

Cutting and 亚博系列全平台入口ming

Induction wear pipe can be successfully cut with plasma cutting or an abrasive cut-off wheel. We do not recommend using Oxy-fuel. The pipe should never be cut lengthwise as the induction hardening process imparts internal stresses in the pipe wall.听

Joint Preparation

Avoid welding areas of pipe that have tears, crack, or other imperfections. Area to be joined should have all loose scale, moisture, rust, grease, etc. removed within 1/2鈥� from welding joint.听

Welding

As any heat applied to induction hardened pipe can affect the wear properties, consult with a Clifton Steel representative prior to welding. We do stock weld wire compatible with hardened pipe-聽Tensaweld Workmate.听

Preheating & Interpass Temperatures

Preheat the weld zone and 6鈥� of the adjacent if ambient temperature of parts is below 70潞 F.听Care must be taken to cool the inner surface. As temperatures approach 500潞 F the inner surface hardness will begin to decrease.

Welding with聽water cooling is the preferred method of welding. Be sure the water does not contact the exterior of the pipe.听An alternate method without water cooling should only be used when water is not available.听
