Mechanical Contractors in Cornwall and the South West.
Mechanical Engineering & Pipework.
Coded welding and pipework in mild and stainless steel, screwed, brazed, Mapress and solvent weld, all pressure tested. We also remove redundant HVAC plant and oil tanks.
What we cover
Send us the pipework drawingsMechanical engineering on a commercial site is rarely one job. It is new pipework, plant that has to come out first, ventilation that needs recommissioning afterwards and a pressure test to prove the whole thing. We handle the sequence, and the welding is coded and carried out in-house.

Common questions
Before you call
What welding standards do your welders work to?
MMA, TIG and MIG in mild and stainless steel, coded and pressure tested.
Can a redundant oil storage tank be removed?
Yes, including decommissioning and disposal. Tanks that have held oil cannot go in a skip, so removal is a controlled job with paperwork behind it.
Do you fabricate pipework off site?
Where the component can be removed, yes. Off-site fabrication cuts the time we spend in a live building, which is usually the expensive part of the job for the client.
Do you maintain heating and ventilation systems?
Planned maintenance and reactive repair on commercial HVAC, along with removal and disposal of plant that has reached the end of its life.
What areas do you cover for mechanical engineering work?
Cornwall and Devon as standard, and further across the South West for specialist pipework and coded welding.
Can industrial pipework be replaced during a shutdown?
That is how most of it gets done. Shutdown work, phased installation and out-of-hours access are normal on this kind of job, and we price the constraint up front.
