Tube erosion shields for industrial steam boiler used for economizer 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 tube shields are designed to eliminate major maintenance and downtime costs from boiler and condenser tube failure.
