Pipe erosion Shields from U-Neek Bending Co
Ash content, high furnace temperature, increased sootblower
pressure and longer time between cleans - all these things result in the
likelihood of greater erosion to boiler tubes. In such cases, the most
effective course of action is to shield the erosion prone tubes with boiler
erosion shields. This alternative is far cheaper than actual replacement of
damaged sections of boiler tube, to say nothing of the associated downtime
and loss of generation capacity and revenue that occurs with a tube leak.
U-Neek Bending Co. Pty Ltd offer various types of erosion shields for boiler
tubes. Typical shields cover a 180° segment of the tube and are 1000mm long.
In addition to straight tube shields, which go over straight sections of boiler
tube, we also make shields to cover bends and special shields for finned tubes.
These include shields for:
- Outside of bend.
- Inside of bend.
- Side of bend.
- Finned tube shields.
We also manufacture clips that may be welded onto the shields to hold the
shields in place. The shields can be manufactured to suit any tube size.
The most common tube sizes are 38.1, 44.5, 50.8, 57.15,60.3 and 63.5mm diameters.
The erosion shields can be made out of mild steel, chrome moly steel, stainless
steel and exotic alloys such as Inconnel. The most popular materials and sizes
are 3mm stainless steel grade 304 and 2mm stainless steel grade UNS S30815
(Sandvik grade 253MA).
