The relatively cumbersome test of FRP pipes was recently improved in one of the trials of the Xinjiang Jiwu Water Supply Pipeline Project, and a simple pressure testing device was manufactured.
In the pressure test of glass fiber reinforced plastic water supply pipes, a rigid connection device for water injection pipes and pressure suppression pipes has been used for a long time, that is, steel pipes are connected between injection ports and multi-pole pumps. Because the position of the multi-polar pump differs from place to place and the depth of the pipe groove is different at each pressure test, the connection between the water source and the pump and the pump and the pipeline must be readjusted. When the rigid connection device is adjusted, there must be gas cutting and welding. The power supply operation is very troublesome under the condition of the power supply, when mistakes, mistakes, spending money, material resources are more.
The engineers and technicians of Xinjiang Jiwu Water Supply Pipeline Project developed a simple and convenient pressure testing device for the inconvenience of rigid connection mentioned above. The principle is: install a flange pipe at the inlet and outlet of the multi-polar pump, equipped with 2 high-pressure hoses of arbitrary length and press the corresponding metal live interfaces at both ends of the pipe. Use a hose to connect the water source and the multi-pole pump, and use another hose to connect the multi-polar pump outlet and the proposed pressure test line blocking plate.
This method has obvious advantages compared with traditional pressure testing structures. According to the Chinese epoxy industry online () reporter, the main is: shorten the assembly time, the traditional pressure test structure assembly time requires about 2 people, the new pressure test device only 1 person, 10 minutes to complete; simplify the operating procedures, The assembly of traditional pressure testing equipment must be equipped with electric welding and gas cutting equipment, while the new pressure testing device only requires one wrench; for cycle use, the traditional pressure testing device is one-time, that is, each testing pressure requires new accessories, while the new device is Can be used multiple times.
