The inner diameter of the u-shaped snap ring is the outer diameter of the wear-resistant tile plus the thickness of the wear-resistant tile, and the length varies from 20mm to 70mm. It will be 5mm more in semicircle. The extra part during installation will hold the wear-resistant tile and then spot weld. Compared with the butt-type semicircular snap ring, it is stronger after holding the wear-resistant tile and welding.

Snap rings are used in conjunction with boiler tube erosion shields, which is a clip that easily installs boiler tube erosion shields to the tube.

The snap ring and boiler tube 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 tube 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 a 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, 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.
