Tubes shield coil heat shield for biomass fired power station is a common component of the heating part of tubes.It is usually used in power station boilers. The useful life of tube shield is 3-5years. The tube shield has a variety of material and the selection of the material shall be subject to the original design of the boiler.The tube shield is divided into straight pipe and bend pipe. The main effect of tube shield is to protect the pipe and increase the service life of the pipe.

Boiler tubing N protection shield is designed to eliminate major maintenance and downtime costs from boiler and condenser tube failure.

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.
