Detailed introduction of "Fuxin polyurethane foam insulation pipe DN900/920 rigid polyurethane insulation pipe"
Fuxin Polyurethane Foam Insulation Pipe DN900/920 Rigid Polyurethane Insulation Pipe Inspection and Acceptance At any time during the manufacture of direct-buried insulation pipes, the buyer or its agent can freely enter the manufacturer, including sub-sellers, to manufacture direct-buried insulation pipes or test site. The Seller shall provide, free of charge, the conditions for checking whether the production is carried out in accordance with the quality and date specified in the contract. The buyer, the buyer's agent or the buyer's agent may inspect the test process of the direct buried thermal insulation pipe, and the seller shall provide reasonable facilities for the work of the buyer or its agent free of charge. 7. documents and certificates The seller must ensure that the directly buried thermal insulation pipes supplied meet the specified requirements and provide corresponding certificates. The certificate shall at least demonstrate that the tests required by this specification and other relevant reference standards or regulations have been performed. A product quality certificate stating the contract number, pipe number and reference to the standard or specification should be provided. All certificates shall be prepared for inspection by the buyer prior to shipment. The product quality certificate and the test report of each batch of directly buried insulation pipes must be submitted to the buyer (three copies) before shipment. The test report includes: -- Test report on the outer diameter of outer protective pipe -- Test report on tensile yield strength and elongation at break of outer protective pipe -- Test report on foam density -- Test report on compressive strength of thermal insulation layer -- Water absorption of thermal insulation layer Test report of rate and closed cell rate--chemical property analysis of steel pipe--mechanical property test results of steel pipe--The data testing unit for automatic recording of the hydrostatic pressure test of steel pipe shall be approved by the buyer. Marking and transportation The marking and transportation of thermal insulation pipes must meet the requirements of "High-density Polyurethane Foamed Plastic Prefabricated Directly Buried Thermal Insulation Pipes and Fittings" GB/T29047-2012. All openings shall be fitted with acceptable industry standard protective devices to prevent damage, corrosion and the entry of foreign objects during transportation and storage. Two plastic heads are provided for each steel tube as protective devices. Inspection rules These rules are formulated in accordance with GB/T 2828. 6.1 Batch The same raw material, the same formula, and the same specification of insulation pipes produced under the same process conditions are regarded as a batch, and the number of each batch does not exceed 50. 6.2 Sampling inspection plan 6.2.1 Plan 1: Qualified quality level AQL
