Erosion Shields
Erosion Shields are designed to eliminate major maintenance and downtime costs from boiler and condenser tube failure.
The 1Cr6Si2Mo erosion shield connector is designed to provide outstanding protection against erosion and wear in high-temperature environments.
Made from high-performance alloy steel, it is widely used in industrial applications where reliability and durability are paramount.
The 1Cr6Si2Mo erosion shield clamp is specifically engineered to provide exceptional resistance to erosion and wear under high-temperature conditions. Made from high-performance alloy steel, it is widely used in industrial applications where reliability and durability are paramount.

1Cr6Si2Mo is a martensitic heat-resistant steel with good oxidation resistance at 800°C. Compared with 1Cr5Mo steel, since it contains 1.5% silicon (Si), the temper brittleness tendency of 1Cr6Si2Mo increases, and brittle fracture may occur when working at high temperatures for a long time. This material shows good corrosion resistance in sulfur-containing oxidizing atmospheres and hot petroleum media.
After normalizing and tempering heat treatment, 1Cr6Si2Mo has high creep strength and durability. In addition, 1Cr6Si2Mo has an air quenching phenomenon. If it cools too quickly after hot processing, cracks may occur, so slow cooling is required.
Its weldability is poor. Electric welding is recommended instead of gas welding. It needs to be preheated to 300°C - 400°C before welding and tempered at 750°C after welding.
The 1Cr6Si2Mo erosion shield clamp is widely used in various industries, including:
Ceramic lined pipe is made through self-propagating high-temperature synthesis (SHS) technique.
Cast basalt lined steel pipe is composed by lined with cast basalt pipe, outside steel pipe and cement mortar filling between the two layers.
Ceramic tile lined pipes have very uniform coating of specially formulated ceramic material that is affixed to the inner of the pipe.
The material of the rare earth alloy wear-resistant pipe is ZG40CrMnMoNiSiRe, which is also the grade of rare earth alloy steel.
Tubes Erosion Shields are used to protect boiler tubing from the highly erosive effects of high temperatures and pressures thereby greatly extending tube life.
The ASTM A213 T91 seamless tubes are primarily used for boiler, superheater, and heat-exchanger.
