Boiler Erosion Protection Shield

 

Boiler erosion protection shield reduce excess wear of boiler tubes within the extreme conditions prevalent inside a fossil fuel fired boiler, we are able to manufacture and supply erosion shield solutions to protect and reduce wear in all applicable boiler related situations. Boiler erosion protection shield to suit any diameter tube can be manufactured from various alloy and stainless steel materials.

Shapes and specifications of tube shields

The cross-sectional shape of boiler tubes shields is mostly semi-circular (180 degrees), and there are also 120-160 degrees. It is mainly used on finned tubes (water-cooled walls); boiler tube erosion shields are divided into direct wear-resistant shields, in-curve, anti-wear shields, outer-curve, anti-wear shields, side-curve anti-wear shields, s-curve anti-wear shields, etc.

Tube shields-outside bend and side bend types

The length of the straight anti-wear shields ranges from 20mm to 3000mm, and the general length of 1000-2000mm is commonly used. The anti-wear shields with bends generally requires a processing drawing and the following parameters should be on the drawing: outer diameter of the pipe used, bending of the pipe Radius R (to the center of the pipe), the degree of bending angle, and the length of the straight sections on both sides of the arc segment of the wear-resistant shields.
