QA&QC

To ensure the production quality of 2 - inch HDPE indoor water supply pipes, strict control measures should be implemented in multiple aspects. Regarding raw materials, high - quality suppliers should be selected, incoming materials should be inspected, and proper storage methods should be adopted. In terms of the production process, the temperature, screw speed, and pressure of the extrusion process should be precisely controlled, and attention should be paid to the mold design, sizing, and cooling steps in the forming process. Equipment requires regular maintenance, calibration, and rapid troubleshooting. Personnel should receive professional training, enhance their quality awareness, and be subject to performance appraisal. For quality inspection, initial piece inspection, in - process inspection, and finished product inspection should be carried out, and a quality traceability system should be established.

Ordering Notes
1.Specify the parameters: Common series for 2-inch HDPE pipes include SDR11 and SDR17. The appropriate wall thickness should be selected based on factors such as the actual working pressure. Understand the length of the pipes. The common lengths of HDPE pipes are 6 meters and 12 meters, etc. They can also be customized according to the on - site construction requirements.

2.Quality standards and certifications: Ensure that the pipes meet relevant standards, such as ISO9001 and CE certification. This can guarantee that the pipes meet the basic requirements in terms of performance, hygiene, etc.
3.Contracts and deliveries: Clearly state key information such as the specification, quantity, price, quality standard, delivery time, and delivery location of the pipes in the contract to avoid disputes in the later stage.
