Preparation before installation of tube heat exchanger:
After the heat exchanger enters the site, a body water pressure test should be carried out. The test pressure should be1.5times the work pressure. The steam part should not be lower than the steam pressure plus0.3MPa;The hot water part should not be lower than0.4MPa. under test pressure10minIt is qualified if the internal pressure does not drop and there is no leakage.
The construction and installation unit should prefabricate the concrete foundation according to the tube heat exchanger foundation design drawing, generally usingC15plain concrete, and the anchor bolts need to be pre-embedded, and the surface of the support must be plastered before installation.MIOThe cement mortar is leveled and the equipment is installed after the foundation strength reaches the required level.
