NDT equipment

The most characteristic of NDT equipment do test without damage to the specimen material, the structure of the premise, so the implementation of non-destructive testing, the product inspection rate can reach 100%.

However, not all projects need to be tested and indicators can be carried out non-destructive testing, nondestructive testing technique also has its own limitations. Some tests can only adopt destructive test, therefore, the nondestructive testing also does not take the place of destructive testing. That is, for a workpiece, materials, machinery and equipment evaluation, must be the result of non-destructive testing and destructive testing and comparing the results with each other in order to make an accurate assessment.

The correct selection of the most appropriate method for non-destructive testing

Since various detection methods have certain characteristics, in order to improve the reliability of test results, which should be based on the device material, manufacturing method, the working medium, the use conditions and the failure mode, the defects can be expected type, shape, location and orientation, select the appropriate NDT methods.

Integrated application of various non-destructive testing methods

Any kind of non-destructive testing methods are not a panacea, each method has its own advantages and disadvantages. As much as possible using several detection methods complement each other in order to protect the safe operation of pressure equipment. In addition, in non-destructive testing applications, but also fully aware that the purpose of detecting excessive demands are not one-sided pursuit of "high quality", but should be sufficient to ensure safety and appropriate risk-free rate of the premise, taking into account their economic focus. Only in this way, pressure equipment, non-destructive testing applications in order to achieve the desired purpose.

Seamless pipe Specification, standard and identification

Seamless pipes are extensively applied for the nuclear device, gas, petrochemical, ship building and boiler industries. Seamless pipes dominates 65% of market share in Chinese boiler industry.
