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 protector elbow undergoes precise fabrication to ensure a snug fit and maximum protection. Welding preheating (300°C-400°C) and post-weld tempering (750°C) are recommended to maintain material properties and reduce residual stress. Custom dimensions are available for seamless integration into existing systems.
Tube erosion shields are precision-engineered to fit straight, curved, finned and specialty tubing, providing continuous protection against fly ash erosion and high-temperature corrosion.
Also known as anti-wear plates or boiler climbing shields. Installed with retaining snap rings to ensure long-term stability on heating surfaces.
Manufactured by high-pressure die forming with dedicated tooling. Bent profiles use press forming or precision mandrel bending for close tube contour conformity.
Robust, weld-friendly assemblies with smooth aerodynamic surfaces. Mitigate tube wall thinning, reduce unplanned maintenance and extend boiler availability.
Generally, boiler tubes erosion shields are also installed to prevent further wear of the tubes and cause serious consequences such as boiler explosion.
The main role is to protect the heating surface of the boiler pipes, reduce pipeline wear, and increase the heating surface of the pipes.
The snap ring is a short section that is installed on the pipe in conjunction with the wear-resistant tile. Generally, it is welded to the wear-resistant tile by lap welding, that is, to cover the wear-resistant tile slightly, so it is larger than the wear-resistant tile. The opening arc is around 190-200 degrees, the welding position needs to be set aside to facilitate welding and fixing. The width of the snap ring must not be less than 20mm.
The installation requirements of anti-friction tiles of different shapes are slightly different. Basically, each anti-friction tile is installed with not less than 2-4 snap rings. The snap ring and the anti-friction tile are welded together to prevent expansion due to heat. The tiles fall off, and the joints are required to be fully welded.
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.
