Tubes Erosion Shields are used to reduce excess wear of boiler tubes within the extreme conditions prevalent inside a fossil fuel fired boiler, Sunny Steel is able to manufacture and supply erosion shield solutions to protect and reduce wear in all applicable boiler related situations.
Tube Shields are custom made to fit perfectly to straight sections, curved sections and even finned and specialised tubing.

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.
Boiler Tube Shields are designed to eliminate major maintenance and downtime costs from boiler and condenser tube failure.
The service life of Boiler Tubes Erosion Shields is different in different types of boilers and different use parts. The normal service life is a period of overhaul (3-5 years) for the boiler. Generally, some boilers will be replaced or retrofitted every time the boiler is overhauled. The main replacements are those of the Boiler Tubes Erosion Shields that are severely thinned and exceeded the standard; those that were not firmly detached during the boiler operation during the previous installation. According to the wear of the Boiler Tubes Erosion Shields during replacement, if the thickness is severely reduced, it needs to be replaced, the deformation is severe, and those that cannot protect the tube also need to be replaced. In addition, some boiler tubes are not equipped with Boiler Tubes Erosion Shields, but during the boiler inspection, it is found that the tubes have a tendency of wear and thinning. Generally, Boiler Tubes Erosion Shields are also installed to prevent further wear of the tubes and cause serious consequences such as boiler explosion.
On the heating surface of superheater and economizer tube bundle of the boiler, in order to prevent the pipe from being worn by high temperature flue gas washing, boiler tubes erosion shields are mostly arranged on the outer side of the pipe in the direction of flue gas flow. The elbow erosion shields solves the abrasion problems of water wall tubes, superheater tubes, economizer tubes and reheater tubes in the furnace, and provides guarantee for the long-term and reliable operation of CFB boiler. With the increase of CFB boiler products, the type and quantity of The elbow erosion shields will increase.
根据不同工作条件的特定条件选择不同类型的不锈钢。常见材料为：TP321（CR18NI9TI），TP309S（CR23NI13），1CR20NI14SI2，TP310S（CR25NI20），1CR25NI20SI2，以及一些低温区域（例如低温，低温，低温reheater）由1CR1CR13、1CR13、1CR6SI2M组成。
锅炉最初设计为准确。不同的材料具有不同的温度抗性和机械强度。1CR13，1CR6SI2MO通常具有600或更少的温度抗性。

我们还可以提供其他材料的锅炉侵蚀罩。
Grade 304 stainless steel is the most versatile and the most widely used of all stainless steels.
CS 309 is a highly alloyed austenitic stainless steel used for its excellent oxidation resistance, high temperature strength and creep resistance.
310级是较低的碳版本，不太容易发生和敏感。
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.
