Main material of tubes erosion shields

Different types of stainless steel are selected according to the specific conditions of different working conditions. Common materials are: TP321 (Cr18Ni9Ti), TP309S (Cr23Ni13), 1Cr20Ni14Si2, TP310S (Cr25Ni20), 1Cr25Ni20Si2, and some low temperature areas (such as low temperature superheater, low temperature reheater) are made of 1Cr13, 1Cr6Si2Mo and other materials.

The boiler was originally designed to be accurate. Different materials have different temperature resistance and mechanical strength. 1Cr13, 1Cr6Si2Mo generally has a temperature resistance of 600 ℃ or less.

Material（Grade）	Temperature resistance	Yield strength	Tensile strength	Elongation	HB	HRB	HV
1Cr18Ni9Ti	925 ℃	≥205MPa	≥520MPa	≥40%	≤187	≤90	≤200
Cr23Ni13	1095 ℃	≥205MPa	≥520MPa	≥40%	≤187	≤90	≤200
1Cr20Ni14Si2	1095 ℃	---	≥590MPa	≥40%	---	---	---
Cr25Ni20	1150 ℃	≥205MPa	≥520MPa	≥40%	≤187	≤90	≤200
1Cr25Ni20Si2	1150 ℃	---	≥540MPa	≥35%	---	---	---

We can also supply Boiler Tubes Erosion Shields of other materials.

304 stainless steel Erosion Shields

Grade 304 stainless steel is the most versatile and the most widely used of all stainless steels.

309 stainless steel Erosion Shields

CS 309 is a highly alloyed austenitic stainless steel used for its excellent oxidation resistance, high temperature strength and creep resistance.

310S stainless steel Erosion Shields

Grade 310S is a lower carbon version, less prone to embrittlement and sensitisation in service.

316L anti corrosion and anti wear steel erosion shields

Grade 316 is the standard molybdenum-bearing grade, second in importance to 304 amongst the austenitic stainless steels. The molybdenum gives 316 better overall corrosion resistant properties than Grade 304, particularly higher resistance to pitting and crevice corrosion in chloride environments.

Boiler Tubes Erosion Shields

Boiler Tubes Erosion Shields, also known as anti-corrosion Shields, anti-wear plate, anti-wear protection Shields, anti-wear cover plate, anti-corrosion cover plate, boiler climbing pipe, anti-wear pressure plate, etc. , which are used in combination with snap rings. Processing thickness of Boiler Tubes Erosion Shields Boiler Tubes Erosion Shields are processed in thicknesses of 2mm, 3mm, 4mm, and 5mm. Different thickness is adopted according to the wear severity and the need of heat conduction. Boiler Tubes Erosion Shields are produced using a high-pressure press and professional mold pressing. The production time is short, the welding performance is good, the welding should not fall off, the surface is smooth, and the appearance is beautiful. Boiler Tubes Erosion Shields with bends are formed by pressing on a press or bending with a special abrasive on a tube bender.

Application of Tubes Erosion Shields

Tubes Erosion Shields are mainly used on the windward side of the heating surface of the boiler, such as superheaters, reheaters, economizers, and water-cooled wall pipes. The main role is to protect the heating surface of the boiler pipes, reduce pipeline wear, and increase the heating surface of the pipes. Service life. In general, most of them are called "wear-resistant tile" and "wear-resistant cover plate". Erosion Shields are special boiler accessories. Generally, most of them are used in power station boilers, small boilers are used less, and some coal chemical industries will also use them. Erosion shields are used to protect boiler tubing from the highly erosive effects of high temperatures and pressures thereby greatly extending tube life. We offer shielding for tubing, covering straight, bent and finned sections, as well as the clips that hold these in place. In the long term, these shields more than pay for themselves, preventing the costly replacement o...

Snap rings for Tubes Erosion Shields

Snap rings are used in conjunction with Boiler Tubes Erosion Shields, which is a clip that easily installs Boiler Tubes Erosion Shields to the tube. The snap ring and Boiler Tubes Erosion Shields are overlapped and welded, generally about 190-200 degrees Erosion Shields is a 180-degree semicircle), but also leave a welding position for easy welding and fixing. Generally, each piece of Boiler Tubes Erosion Shields needs to be equipped with 2-4 snap rings with a pitch of 200-500mm. The anti-wear snap ring is also called clamp, buckle, tube clamp, etc. The main role of the anti-wear tile snap ring: the role of fixing the anti-wear tile to avoid problems such as the anti-wear tile falling off during installation. The types of common anti-wear tile rings can be divided into: U-shaped lap type snap ring, butt-type semicircular snap ring. Install erosion shields with snap ring The snap ring is a short section that is installed on the pipe in conjunction with the wear-resistant tile. Generally...
