Boiler Tubes Erosion Shields Custom

Description

The service life of Boiler Tubes Erosion Shields is different for different types of boilers and different parts of use. The normal service life is an overhaul cycle of the boiler (3-5 years). Generally, some Boiler Hoods are replaced or installed every time a boiler is overhauled. , the main substitute is the wear-resistant ceramic tile with serious wear, thinning and exceeding the standard; the previous installation was not firm and fell off during the operation of the boiler. When replacing, according to the wear of Stainless Steel Erosion Shields, those with serious thickness need to be replaced, those with serious deformation and those that cannot protect the pipes also need to be replaced. In addition, some boiler tubes are not fitted with Half Round Shield For Boiler Tube, but the tubes are found to have a tendency to wear and thin during regular inspections of the boiler. Tube guards are usually installed to prevent further wear and tear of the tubes, leading to serious consequences such as boiler tube explosions.

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 tubes 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.

Tube shields-outside bend and side bend types

The length of the straight anti-wear shields ranges from 20mm to 3000mm, and the general length of 1000-2000mm is commonly used. The anti-wear shields with bends generally requires a processing drawing and the following parameters should be on the drawing: outer diameter of the pipe used, bending of the pipe Radius R (to the center of the pipe), the degree of bending angle, and the length of the straight sections on both sides of the arc segment of the wear-resistant shields.

“snap-on” type shield

The most basic parameter of boiler tubes shields is the outer diameter of the tube used (that is, the inner diameter of boiler tubes erosion shields). The main specifications of the tube are: 32, 38, 42, 44.5, 48, 51, 57, 60, 63.5 , 76, 89mm, etc . the inner diameter of the boiler tubes erosion shields is usually 1-3mm larger than the outer diameter of the tube used, depending on the actual requirements.

Tube shields production process

To ensure the accuracy of the material. Positive Material Identification (PMI) of stainless steel sheets for tube shields is critical to verifying the grade and composition of stainless steel before it goes into production.
Tube shields from us are manufactured to exacting standards. Advanced equipment and material handling capabilities permit us to offer the fastest turnaround times anywhere.
The current production process for tube shields is to use high-pressure presses and professional moulds for pressing.
The production time is short, the welding performance is good, the welding seam does not fall off, the surface is smooth and the appearance is beautiful. The arc-shaped wear-resistant tile is pressed on a press or bent on a pipe bender with a special mould.
