Advantages
- Anti-corrosion performance: HDPE to steel pipe transition joint has very good anti-corrosion performance. Because this joint adopts 3PE anti-corrosion or galvanizing treatment, this joint is very durable and the comprehensive life can exceed 30 years.
- Easy installation: It adopts a compression joint, no welding is required, and the single-point installation time is less than or equal to 15 minutes, which saves 50% of the time cost compared with traditional flanges.
- Reliable sealing: O-ring + injection molding layer double sealing is adopted. The results of the air tightness test show that the leakage rate is ≤1×10-⁶ mbar-L/s.
