Factory Inspection Of FRP Pipes

- Jul 25, 2017 -

9. 2. 1 Inspection Project

Appearance quality, size, Babbitt hardness, resin insoluble content, pipe wall component content, water pressure leakage, initial ring stiffness, initial tensile strength, initial axial tensile strength, initial deflection, initial circumferential bending intensity.

9. 2. 2 Inspection Program

9. 2. 2. 1 each frpm tube shall be inspected for appearance quality, size (except inner liner thickness) and Babbitt hardness.

9. 2. 2. 2 with the same materials, the same process, the same specifications of 100 root frpm tube for a batch (less than 100 root also made a batch), the thickness of inner liner layer, insoluble content of resin, component content of pipe wall, initial ring stiffness, initial tensile strength, initial axial tensile force, initial deflection and initial circumferential bending intensity were tested by randomly extracting 1 roots.

9. 2. 2. 3 The inspection quantity of water pressure leakage shall be determined by both the supply and demand parties, but not less than l%.

9. 2. 3 Rule of Judgement

9. 2. 3. 1 appearance quality, size (in addition to inner liner thickness), Babbitt hardness should meet the corresponding requirements, otherwise the root canal is not qualified.

9. 2. 3. 2 inner liner thickness, insoluble content of resin, component content of pipe wall of straight pipe, initial ring stiffness, initial tensile strength, initial axial tensile strength, initial deflection, the initial circumferential bending strength inspection and water pressure leakage meet the corresponding requirements, the batch of products qualified; If the water pressure leakage inspection is unqualified, the pipe is carried out by ROOT to carry out the water pressure leakage inspection, and the approved root canal is qualified by the project;

The insoluble content of lipid, the component content of pipe wall in straight pipe section, initial ring stiffness, initial axial tensile strength, initial flexural strength, and the initial ring bending strength inspection of the unqualified items more than 2 items, the batch of products unqualified; if not more than 2 items, the unqualified items can be doubled sampling, retest, retest ear should all meet the requirements, otherwise, the batch of products unqualified.
