Acceptance of fiberglass pipe fittings
Thread Content
How is the acceptance of fiberglass pipe fittings determined once they arrive at the construction site? Is it simply by checking the thickness alone?
According to the manufacturer’s samples~ material grade (whether it is conductive, product series), thickness, dimensions. . .
The manufacturer should provide test certificates regarding strength, dimensions, wall thickness, and so on
Inspection is carried out according to the ordering requirements.
Generally, it involves the diameter, thickness, straightness of the pipe, and its appearance. You can ask the manufacturer for a material certificate, which will make the information relatively complete.
Is there a qualification certificate for performance?
For Buguangshi inspection, things like dimensions are important, but what’s crucial is to use a flashlight to shine on the inner walls in order to check for any breaks, cracks, etc
First, check the appearance and whether the quality certification documents are complete; then, based on the contract, verify the specifications, model, and quantity.
Check the manufacturer’s product certificate and quality certificate, and also look at the contract!
Products leaving the manufacturer’s factory are definitely of qualified quality; what I want to know is how to verify whether they are indeed qualified.
