Equipment / Process
1. Customer demand=high-quality product + high-quality construction team, both of them are indispensable.
2. All main welding and detection equipment during construction are imported from foreign countries.
3. Self-provided generator
4. Large-area HDPE geomembrane construction adopts dual-track hot wedge welding machine for welding.
5. Pipe, corner, node, damaged parts and the parts where the dual-track hot wedge welding machine fails to weld must adopt single-track extrusion welding machine for construction.
6. Double-pass welding seam is detected by air filling method (all)
Single-pass welding seam is detected by vacuum process (all)
