Anti-cavitation valve overhaul

We were asked if we could repair some anti-cavitation valves for Welland and Deeping Internal Drainage Board, Pode Hole, Spalding. As you can see the valves were in very poor condition and had been subjected to some quite arduous conditions, but once pulled apart and inspected we were able to repair and make them fully operational again. In total we were given 6x of these valves, all done one by one, each one needed slightly different work doing to it than the other, but all the corrosion was removed, new 40mm thick solid stainless steel arms were machined and fabricated in place of the rotten units. All the bronze hinges were stripped and overhauled, holes reamed and pins polished. All the broken cast sections were removed and replaced with water jet cut stainless steel profiles. New seals made and bonded in place, then any exposed metalwork shot blasted at a local company called Blast off (www.blastoffservices.co.uk) and coated in chlorinated rubber paint. The client then installed these and remarked on how much better their pumps worked, which resulted in less energy being consumed also!

 

Stainless steel screen for interceptor tank and wier

Fabrication of bespoke stainless steel filter screen for a petro-chemical works. The original unit was beyond repair and the media used for filteration obsolete so we were asked to come up with a long term solution to the problem. The frame on teh screen can be split into two like a sandwich, so that should the screen material become damaged then it can be easily replaced. The work also included the fabrication from old 1960’s drawings a new water weir tank for the same project, This was fabricated in mild steel and hot dip galvanised afterwards

 

Swede cutting prototype

After being approached by a major supermarket beginning with M, we were asked to come up with a simple way to top and tail swedes as their existing practice was labour intensive and at times dangerous if the operative wasn’t too careful with their cutting blades!

 

This is the result, a cleanly cut product replcated time and time again
