BAIJIAN - Third party testing organization
Fiberglass steel pipes、 pipe fittings、 and pipelines are widely used in chemical industry、 oil fields and mines、 coastal pipeline engineering、 and water transportation engineering due to their lightweight、 corrosion-resistant、 convenient installation、 and large transportation capacity. Testing fiberglass pipes can help us provide data support in quality acceptance、 procurement promotion、 market research and development、 and other aspects. In addition、 some failure analysis and defect analysis of glass pipelines can help us avoid safety risks in related projects
Key recommended testing items for fiberglass steel pipes and fittings
1. Testing items for fiberglass felt raw materials
Recommended testing items for fiberglass felt raw materials include: unit weight、 weight change rate、 width、 single fiber diameter、 fiber short cut length、 adhesive type、 glass composition、 weight per roll、 etc
2. Recommended testing items for resin raw materials
The hardness of resin raw materials needs to be measured using a Barcol hardness tester.
. The requirement is not less than 40. In addition、 the resin content also needs to be tested、 and both the intermediate layer and inner lining layer need to be tested. The requirement for resin curing is not less than 85%3. Mechanical Property Testing Items
The recommended testing items for the mechanical properties of fiberglass steel pipes include tensile strength、 bending strength、 bending modulus of elasticity、 circumferential tensile strength、 circumferential modulus of elasticity、 axial tensile strength、 axial modulus of elasticity、 and compressive strength
4. Hydrostatic Testing
In order to comprehensively test the quality of fiberglass steel pipes、 pressure testing should be carried out according to the test methods specified in the "Code for Construction and Acceptance of Water Supply and Drainage Pipeline Engineering"、 The allowable water seepage shall be carried out according to the standard of fiberglass steel pipes. Due to the fact that fiberglass pipes are connected by double "0" shaped sealing rings、 each installed pipe should be pressurized at the socket to test the sealing effect of the double "0" shaped sealing ring. The water pressure test should pass a 10 minute pressure stabilization test at room temperature at 1.25 times the design pressure. In addition、 a short-term hydraulic failure test is also required
