Core Quality Control Checklist‑Table
1. Raw Material Quality Check
Raw‑material quality decides the long‑term service life of double‑wall corrugated pipes. Unqualified plastic particles will cause pipe leakage, cracking and aging problems in later application. Before starting DWC pipe extrusion work, operators need to test raw materials strictly.
2. Online Monitoring During Extrusion
Stable parameters of the DWC pipe extrusion line are very important. Fluctuated temperature or speed will lead to defective products. Workers should watch the running data of extruder, mould and vacuum tank all the time during production. Timely adjustment can greatly reduce waste rate.
3. Final Inspection for Finished Pipes
After cutting, finished double‑wall corrugated pipes need appearance inspection and physical property test. Check whether there are scratches, holes, deformation on pipe surface. Ring stiffness test is one of the most‑concerned indexes by underground drainage project buyers.
