Technical Field
The utility model relates to a pressure testing frock, in particular to heat exchanger is with general type pressure testing device belongs to heat exchanger technical field.
Background
When the shell side pressure test process of the U-shaped pipe or the floating head heat exchanger is carried out, an integral pressure test ring is needed, and the pressure test ring needs to have enough thickness due to the fact that pressure needs to be borne. The prior pressure test integral type pressure test ring has no universality and reusability, each type of pressure test ring can be used only once, and materials are wasted. When the tube plate made of special materials, such as a titanium tube plate, is encountered, the integral pressure test ring usually adopts a surfacing or composite forged piece in order to save materials, the surfacing or composite cost is high, and the manufacturing period is very long.
In order to reduce the manufacturing cost and the number of pressure testing rings, a universal pressure testing device for a heat exchanger is urgently needed to solve the problem.
