Our customer had a problem with constant wearing of pneumatic pipe bends by abrasive materials being blown along the pipes. Dust and product was been blown outside the piping causing a health and safety issue.
Replacement pneumatic pipe bends are usually heavy and awkward to install and so are often replaced by tape or a temporary repair such as steel plate welded on. This is often dangerous as on site welding can cause dust explosions and other problems.
To help our client we carried out modifications, changing the pipe work and incorporating a light weight Polymer cast elbow bend which is suitable for abrasive products. These new elbow bends result in a different type of turbulence in the bend with the product wearing against itself and not the pipe wall. This area was also designed to self-clean so no residue is left in the bend and it is virtually wear resistant.
