Tooling for simultaneous pressure test of multiple heat exchange tubes and using method thereof

Abstract

The invention discloses a tooling for simultaneous pressure test of multiple heat exchange tubes and a using method thereof, which belongs to the field of pressure vessel manufacturing, and overcomesthe defects that the pressure test efficiency of the heat exchange tubes in the prior art is low and unsafe. The structure of the tooling for simultaneous pressure test of multiple heat exchange tubescomprises a pipe cap (1), a steel pipe (2), a steel pipe pump joint (3), pipe joints (4), high pressure belts (5), and heat exchange tube water intake and compressing sealing clamps (6); the pipe cap(1) is welded to the steel pipe (2) to seal one end of the steel pipe; the other end of the steel pipe (2) is welded to the steel pipe pump joint (3); a plurality of pipe joints (4) are welded in parallel to the steel pipe (2); and the steel pipe pump joint (3) is connected to a pressure test pump. The pressure test tooling is placed on a working platform flat-wise, the pipe joints (4) are connected to a plurality of high pressure belts (5) and a plurality of heat exchange tube water intake and compressing sealing clamps (6), and the remaining pipe joints (4) are uniformly sealed; the pressure test pump is started, and all the heat exchange tube water intake and compressing sealing clamps (6) are fastened after the water outlets of the heat exchange tubes start to discharge water; and thepressure test is carried out in accordance with a heat exchange tube pressure test procedure. The invention has the advantages of simple structure, strong practicability and easy operation, and is suitable for pressure test of heat exchange tubes of different specifications.

Description

[0001] Technical field [0002] The invention belongs to the field of pressure vessel manufacturing and relates to simultaneous pressure testing of multiple heat exchange tubes. Background technique [0003] The heat exchange tube is an important part of the pressure vessel heat exchanger, and each tube must be tested for pressure before assembly. The existing technology is to conduct a single pressure test on the heat exchange tube, and the efficiency is very low. In addition, during the single heat exchange tube pressure test process, due to the small volume of the single heat exchange tube, in the process of boosting the pressure, it is not suitable for the test pressure. It is easy to control, and it is easy to cause the actual pressure to be too large and the pressure to rise too fast, causing damage to the heat exchange tube and the pressure test workpiece, which is unsafe. Contents of the invention [0004] The technical problem solved by the invention is to over...
