Specification: Φ16-Φ250Product performance characteristics:1. Has higher long-term hydrostatic strength2. High impact resistance:3. Excellent wear and corrosion resistance:4. Excellent resistance to cracking:Application areas:1. Mainly used in urban gas sub-high-pressure pipelines and some high-pressure pipeline transmission and distribution systems;2. Petroleum transportation; 3. Industrial pipelines; 4. Mining pipelines.

Specification: Φ20-Φ630Application areas: trenchless technology (horizontal directional drilling method, U-shaped method, reduced diameter method, pipe burst method, pipe penetration method, etc.) and excavation and construction of gas pipelines for sand-free landfill (backfilling of original soil).Features: The new construction method has no sand and original soil backfill and trenchless construction methods, bid farewell to the traditional time-consuming, labor-intensive, high-cost excavation engineering work mode, and save a lot of costs.

Specification: Φ20-Φ630Application areas:a: Natural gas, liquefied gas, coal-bed methane and other transmission and distribution pipelines.
