What testing contents do you want to ensure that the quality of the steel skeleton PE composite pipe is good?

Release date:2018-07-19 Author: Click:


  

In order to ensure the construction quality of the pipeline after the completion of the construction, we need to do a series of quality testing of the pipeline, PE steel skeleton composite pipe maintenance of different pipelines in the quality testing content and procedures will be different, for the steel skeleton PE composite pipe in the pipeline quality testing needs to do the following inspection Test the content.



First of all, carefully check whether the edge is normal and uniform, using the edge measuring device to measure its width should be within the specified size range, to see that the bottom of the edge of the welded interface should not melt and lack of cracks.


Secondly, we should carefully monitor the normal production items of steel skeleton PE composite pipe such as data, appearance, color, standard standards, and carry out short-term hydrostatic strength test, peel strength test and ring stiffness test for each batch of pipe.

Maintenance of PE steel skeleton composite pipe

 

3. After cutting off the edge, check that there should be no contamination at the bottom of the edge and the weld interface of the pipeline. If the quality of the welder's interface is not up to standard, double sampling inspection should be carried out on the welder's interface. If the welder's interface is found to be unqualified, then all the welder's construction interfaces will be reworked.


Fourth, the final inspection equipment, universal testing machine, tensile testing machine, carbon black content tester, melt activity tester, moisture tester, and so on, and a sound inspection inspection principle as a guarantee, steel skeleton PE composite pipe production process random self-inspection, patrol inspection, all check contact.



Every item of pipeline inspection can not be ignored. Every inspection procedure needs us to carry out careful investigation according to the regulations and requirements. Therefore, in the actual inspection process, we hope that we can strictly follow the standards to avoid missing important mistakes and causing unnecessary economic losses.
