PVC-UH pipe color: blue,
High strength and corrosion resistance
MRS≥25mpa is required for PVC-UH pipe mixture.Therefore, the water pressure resistance, impact resistance and tensile strength of the pipe are better than the common pipe.
The link is convenient, reliable and stable
PVC-UH pipe adopts one - piece forming steel frame sealing ring: the feature is that the rubber ring and the flared forming one, so the installation will not be moved by extrusion, improving the tightness.
Online stress test
Cash production process, higher testing requirements, pipe at 2 times the nominal pressure for factory pressure test, to ensure that the product is 100% qualified.
Excellent sanitary performance
Pvc-uh pipe adopts organic tin and calcium zinc formula instead of the traditional rechecked lead salt formula, realizing the green lead-free formula system, so that the water quality is more hygienic.
It has a wider range of applications
Building water supply
Small-caliber PVC-UH pipes can be widely used in construction water diversion pipes with advantages of low cost, corrosion resistance, high strength, reduced maintenance and replacement.
Municipal water supply, pipe gallery construction, water conservancy projects
The large caliber PVC-UH pipe can replace cast iron pipe and cement pipe with good fluidity, light quality, low cost and easy installation.
Medium water and chemical medium transport, municipal pressure drainage, etc.
Compared with PVC-U pipe, PVC-UH has the following advantages
The ingredients are more stringent
Increase in large-caliber specifications
Compared with PVC-U pipe, pvC-UH pipe diameter increased to 1600mm
Higher test requirements
The flattening test and performance index of annular tensile strength are added, and the requirement of external force is increased compared with PVC-U pipe, so that the pipe can meet the performance requirement of large-diameter pipe gallery construction.
Compared with the test requirement of PVC-U pipe, the hydrostatic test parameter standard is higher
Unique connection mode
Pvc-uh pipe adopts different connections from PVC-U pipe:
1. One-piece steel framework sealing ring structure: the integration of the rubber ring and the flange avoids the hidden trouble such as the misplacement, deformation and movement of the rubber ring during the pipe installation process, improves the sealing performance of the links, and ensures the installation quality.
2. Full-plastic connectors: Solve the problem of full-plastic connection of large-diameter PVC pipe.PVC-UH pipe system introduced full plastic connectors, realize the same life of pipe fitting and pipe material, truly realize the replacement of steel with plastic.The service life of the whole pipeline is guaranteed for more than 50 years.
