Inspection process
a pressure vessel is that contains have a lot of content and procedures of the
process. As far as we know Zheng Guo VesselCo., Ltd., to complete the inspection of
pressure vessels, need to include checking drawings, container technology
parameters, testing methods ,sites, programs and others.
First, let's introduce you knowledge about testing procedures. To carry out a complete pressure vessel testing, you need to follow the following order: Turn off the machine - cut off - turn off the device associated valve - replacement cleaning equipment - remove trim - removed insulation, sandblasting, rust etc. - internal and external macroscopic examination - to eliminate defects in the work - the middle of testing - hydrostatic testing - final testing.
The above program is a complete testing procedures. In addition to this program ,we need to know, but Zheng Guo Vessel Co., Ltd., believes that there are some essential factors that we need to note that during the detection.
1. different detection methods corresponding to different testing requirements. For example, the detection of internal defects choice ray testing, ultrasonic testing; detecting surface defects optional magnetic particle testing, penetrant inspection and eddy current inspection; detection pores, slag volume for a class-like defects can be the first choice of radiographic inspection; detection of internal cracks a class of linear defect , mainly used ultrasonic testing first.
2.about the operating parameters of the pressure vessel, pressure, temperature, structure and other factors.
Pressure vessel temperature, pressure, medium ,material and other factors will affect the generation and propagation of defects. In the development of test programs should make specific analysis, it were to be treated.
3. The structure and shape of the pressure vessel, the installation location and other factors.
Different structural forms of the container, the required detection method using different analysis should be targeted, effective approaches. For example, the container is mainly to check the welding zone of welded joints defects, forging container housing the main check forging forging internal cracks, surface
cracks and folds, monolayer and multilayer container ,claddingcontainer, lined vessel and so on.First, let's introduce you knowledge about testing procedures.

In addition, the testing of pressure vessels, they also need to pay attention to the location of the container and a series of other factors. Zheng Guo Vessel Co., Ltd.,said that this is a complete working system, Be sure to rigorous execution.
