Abstract

The invention provides a pressure test tool for a floating head heat exchanger. The pressure test tool comprises an equipment flange, an equipment stud, an equipment nut, a gasket, a tool flange, a filler, a gland, a pressure test nut, a pressure test bolt and a floating tube plate, wherein the equipment flange and the tool flange are connected through the equipment stud and the equipment nut; thetool flange and the gland are connected through the pressure test bolt and the pressure test nut; the equipment flange and the tool flange are sealed through the gasket; and the floating tube plate,the tool flange and the gland are sealed through the filler. The pressure test tool has the advantages of being convenient to install, good in pre-tightening effect, safe and reliable in performance and capable of being repeatedly used.

Description

technical field [0001] The invention relates to a pressure test tool for a floating head heat exchanger used in the petrochemical industry. Background technique [0002] With the development of the chemical industry, more and more heat exchangers are used in the petrochemical industry, among which floating head heat exchangers are used more and more. This kind of heat exchanger is easy to clean and maintain, and can deal with uncleanness and easy scaling medium, and can withstand high temperature and high pressure. But the pressure test of the tube head of the floating head heat exchanger is a difficult point in the manufacture. Contents of the invention [0003] In order to overcome the disadvantages of the prior art, the invention provides a pressure test tool for a floating head heat exchanger. [0004] The technical solution of the present invention is: a pressure test tooling for a floating head heat exchanger, which is characterized in that it includes: equipment f...
