Industry Pain Points — When Conventional Piping Becomes the Weak Link

In oil & gas extraction, chlor-alkali/soda ash production, and large-scale municipal projects, piping systems face three extreme challenges:
| Pain Point | Conventional Solution Failures (Rubber-Lined Steel / Stainless / FRP) | Hidden Costs Incurred |
| 1. Combined Corrosion & Abrasion | Simultaneous attack from strong acids, alkalis, and high-salinity slurries causes delamination of lined steel and pitting corrosion of stainless steel in chloride environments. | Unplanned shutdowns, environmental fines from leaks, high labor costs for replacement. |
| 2. Temperature Cycling & Large-Diameter Pressure | Embrittlement at low temps (-36°C risk of bursting), softening at high temps (>100°C loss of strength). Forming large diameters (>DN1000) under high pressure is difficult. | Forced use of expensive titanium or heavy rubber-lined carbon steel. Heavy weight complicates installation. |
| 3. Installation Efficiency & Sealing Integrity | On-site welding of flanges and repair of internal lining is cumbersome and quality control is challenging. Flange gasket areas become the primary corrosion entry point. | Extended construction timelines. Safety hazards associated with hot work (welding). |

Our Product — Reinforced Nylon & Steel-Nylon Composite Technology

We don't just supply pipe; we deliver “Polymer Alloy Solutions”validated by 40 years of rigorous service in “Petroleum, Chemical, and Mining” industries.
Two Core Series, Full Pressure Range Coverage:
1. Reinforced Nylon Pipe (Full-Plastic Reinforced)
Core Advantages: Ultimate corrosion resistance, non-toxic, lightweight, “integrally molded flange”.
- Application: Strong corrosive, pure media transport up to 1.6 MPa.
2. Steel-Nylon Composite Pipe (Rigid-Flexible Hybrid Structure)
Structure: Outer high-strength carbon steel bears pressure load; inner dense Nylon liner isolates all corrosive media.
Core Advantage: “Pressure rating up to 4.0 MPa”. Solves the industry paradox of "extreme corrosion resistance + high pressure containment."
Nylon Material Performance Data Sheet:
| Performance Metric | Rating | What It Means for You |
| Abrasion Resistance | 5-7x superior to standard HDPE | Extended service life when transporting slurry or phosphogypsum tailings. |
| Temperature Range | -36°C to 160°C | No cracking in arctic freezes; no deformation during steam purging. |
| Chemical Resistance | Full spectrum: “Weak acids, strong alkalis, concentrated brine” | Suitable for entire chlor-alkali and soda ash process streams. |
| Health & Safety |“Non-Toxic, Zero Leaching” | Certified for potable water standards. Safe for municipal supply. |
| Dimensional Capability | Up to ≥ DN2000 mm | Superior alternative to concrete box culverts: higher flow capacity, lower roughness coefficient. |
