Hey folks, it's been that busy I've not even found time for an update, so here's a cheeky post for you...
This heat exchanger blossomed from a simple split end cap but further teardown revealed a host of other issues. Top marks for my good buddy and no. 1 welder, Stu who welded up the outlet fl**ge for me so I could reface it...I'm 30 years of salt air has taken its toll and had eaten away a lot of material. I also had to fit a new mixer elbow as the water jacket had corroded down to a pinhole! This also caused one of the tubes to blow in the nest so plugging the offended tube was also needed.
After a descale, new seals, gaskets, refaced end, repaired threads, new copper flashed nuts, new end caps, repaired and pressure tested nest and a new stainless steel elbow, it's all back together and on the money!
Funny how a seemingly small symptom can have so many underlying problems. Such is the way with boats. Look after your machinery folks and it will look after you!
