Boiler tests

Post  Chrs777 on Fri 02 Jun 2017, 7:14 am

Just curious at the moment. But can I ask how often the steam test and hydraulic test are needed ?
For a 4" burrell agricultural.
If it takes 2 year's to build an engine, does that mean that the certificates that the boiler comes with are not valid at that time ?

I've just completed my 4" SCC and had to get a hydraulic and a steam test. Hydraulic test was to 1.5 times rated pressure and for there to be no major leaks. For the steam test I had to show that the safeties lifted and fell at correct pressure, water pump and injector worked and that everything else looked okay.

The engine will require a steam test every year and a hydraulic test every two years.

Regardless of date of boiler certificate you will need a hydraulic and steam test when the engine is completed.

Hydro test every 2 years for a club inspection. 7 to 10 years for commercial inspection.

The first hydraulic test (1.5 times) on a steel boiler is when the engine is complete. The 4 year test on a new boiler is irrelevant really as once it's fittings have been added it has to be tested again. I have argued the point with the Southern Federation about them saying it's a 4 year test as it's misleading and leads to much confusion. They have agreed but changing wording is a long winded process for them. It's done initially at double the working pressure to prove the soundness of the boiler, giving it a time scale or life is irrelevant, once it's been done & passed that's all you want to know. When the engine is complete get it done again to 1.5 times working pressure to test all the fittings and that lasts 2 years.

On steel boiler he first test is to 2xWP and lasts until the boiler is replaced or has major work (undefined).

It is then built up with all it's fittings and given a further hydraulic test to 1.5xWP. This test is valid for 4 years, irrespective of whether or not the boiler is steamed during that period. At the end of that four years the boiler is presented for another 1.5xWP test which is valid for 2 years, repeated every 2 years.

We are going to have to agree to differ on that one.

Sorry, it's in the book, in black and white, and I am a club boiler tester
