Machine, compressor, pump and boiler etc. pressurization after, flowed at low pressure from the high pressure of pipeline, can also be used fluid itself pressure or
Gravity conveying, having many uses for pipeline is general, is used primarily in water supply, draining, heat supply, gives gas, long distance delivery petroleum and natural
In gas, agricultural irrigation, hydraulic engineering and various commercial plants, these pipelines provide channel for various daily necessities, make us
Life it is lighter, if however these pipeline improper uses, serious security risk can be generated, the pipeline for transporting water pipe is let out
Leakage will lead to the waste of water resource, and the pipe leakage for transporting combustion gas will have the danger etc. of explosion, and pipeline may bear many
The effect of kind external force, including the weight (weight of pipe, valve, pipe connector, insulating layer and tube fluid) of itself, fluid
Pressure act on the thrust of pipe end, wind and snow load, ground pressure, expand with heat and contract with cold caused thermal stress, oscillating load and earthquake
Disaster etc., in order to guarantee the strength and stiffness of pipeline, it is necessary to various branch are set and (hang) frame, such as movable support, fixed bracket, guiding
Bracket and spring support etc., the setting of bracket are fixed according to conditional decisions such as the diameter of pipeline, material, pipe wall thickness and load
Bracket is used to the thermal stretching of Discrete control pipeline, makes expansion joint uniform operational, and guiding trestle moves axially pipe only, in order to
Guarantee pipe safety operation and occur to prevent fault spread in time when accident, except installing detection control instrument and safety on pipeline
Outside valve, specific safety measure is also taken to certain critical pipings, as in gas piping and long distance delivery oil and natural gas
Accidental depressurization valve or urgent block valve are installed on pipeline, they can stop conveying in time automatically when disastrous accident occurs,
To reduce casualty loss, the pressure tolerance of pipeline is an important consideration index to pipeline quality, the pipe of different purposes
Road, needs to meet the pressure tolerance of various criterion, and pressure exerting arrangement is exactly for a kind of survey to pipeline pressure ability to bear
Test-run a machine structure.
But there are some drawbacks in use in the pressure exerting arrangement of traditional pipeline pressure test, such as:
The pressure exerting arrangement of traditional pipeline pressure test cannot quickly carry out multiple pipelines in use
Pressure test needs that pipeline is fixed and is installed manually in test, can just be tested, more in test sample
In the case of, test speed is more slow, has seriously affected testing efficiency.
The pressure exerting arrangement of traditional pipeline pressure test in use cannot be simultaneously to the resistance to compression energy inside pipeline
The anti-pressure ability of power and pipeline external is tested simultaneously, and pipeline of today in the work environment, the feelings such as is often squeezed
Condition does not adapt to working environment of today equally if external anti-pressure ability is insufficient.
