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.

All these years have enhanced our capabilities and enabled us to produce all kinds of standard tube shield as well as custom snap rings as per customer’s specifications. We have numerous combinations of sizes readily available in large number of stocks and can fabricate custom sizes according to customer’s requirement.

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.
