Underground chilled water pipes
I have to embed around 15 meters of chilled water supply and return lines. I will give them min two coates to epoxy paint, insulate them with rigid fiber glass pipe insulation having vapor barrier over it, and finally wrap around the whole length with denso tape. Please do share if I have missed something. *I have read somewhere that pipe should be painted with two coats of zinc chromate, does it give a better protection against moisture. Thanks
Sleeve for chilled water pipe !
Does an underground chilled water pipe entering a building through grade beam or a wall require any kind of pipe sleeve. If so, what should be the material of the sleeve if the pipe entering is carbon steel, Sch 40. Thanks
