Product Description

What is a stator cooling water filter:

The Boiler Tube Shield R26 L1300 is used for the windward surface of the heating surface pipe of the boiler such as superheater, reheater, economizer, water wall pipe, etc., to protect the boiler pipe from the wind surface, reduce pipe wear and increase the service life of the pipe on the heating surface. In the general industry, it is called "anti-wear cover", which is also called anti-wear cover, anti-wear plate, anti-wear protection tile, anti-wear cover plate, anti-corrosion cover plate, boiler creeping tube, anti-wear plate, etc. Commonly used accessories for face tubes, used in conjunction with snap rings.


The materials of Boiler Tube Shield:

stainless steel: 1Cr18Ni9Ti (321), Cr23Ni13 (309S), 1Cr20Ni14Si2, Cr25Ni20 (310S) 1Cr25Ni20Si2, also some low temperature areas (such as low temperature superheater, low temperature reheater) using 1Cr13, 1Cr6Si2Mo and other materials, materials The selection of the boiler is generally based on the initial design of the boiler. Different materials are resistant to temperature and mechanical strength.

Shape:

Most of them are semi-circular (180 degrees), also have 120-160 degrees, divided into straight Boiler Tube Shield, inner curved Boiler Tube Shield, external curved Boiler Tube Shield, side curved Boiler Tube Shield, S-curved wear-resistant Boiler Tube Shield and so on. Straight Boiler Tube Shield length 20mm-3000mm, 1000-2000mm is more common;

Curved wear-resistant Boiler Tube Shield are generally required to provide processing drawings with the following parameters: pipe outer diameter, pipe bending radius R (to the center of the pipe), bending angle and length of both sides of the wear-resistant arc.


Installation:
Basically, each piece of Boiler Tube Shield is installed with not less than 2-4 snap rings, the snap ring and the Boiler Tube Shield are fastened together, and the overlap is fully welded.

The Boiler Tube Shieldof the boiler economizer should be fixed at one end for welding, and the other end should be welded to hold the card so that it can freely expand and prevent it from falling off.

The installation of Boiler Tube Shield for boiler water wall tubes requires welding with fins. Intermittent welding is used. There is a 50m continuous weld seam per 200m. The number of continuous welds on each side of each wear-resistant tile is not less than 2, and the wear-resistant tile Do not weld directly to the water wall tube.
