Steel-Nylon composite straight pipe
**Structural Engineering:** The high-strength steel outer shell ensures pressure ratings **up to 2.5 MPa**. The inner lining is a specially modified **MC Nylon**, known for its self-lubricating properties and low friction coefficient. It delivers not only superior corrosion resistance but also **exceptional resistance to high-velocity solid particle erosion**.
**Extreme Temperature Performance:** Operational range from **-36°C to +160°C (-32.8°F to +320°F)**. Maintains excellent toughness in sub-zero environments without embrittlement and retains dimensional stability under elevated temperatures.
**Broad Chemical Compatibility:** Exhibits excellent resistance to **weak acids, strong alkalis, and a wide range of salt solutions**. An ideal upgrade for transport piping in **chlor-alkali, soda ash, salt chemical, and phosphoric chemical industries**.
Steel-nylon composite straight pipe with a steel structural shell, cast MC nylon lining and integrated flange connections. Published range: DN100-DN2000, 0.25-2.5 MPa and -36°C to +160°C, subject to the selected design and operating conditions. Designed for compatible corrosive and abrasive industrial media. Send your medium, temperature, pressure and dimensions for a project-specific recommendation.Steel Strength with a Nylon Working Surface
Our steel-nylon composite straight pipe combines a steel structural shell with a cast MC nylon lining. The steel provides mechanical support, while the nylon forms the surface in contact with the conveyed fluid. This construction is designed for industrial systems where corrosion, abrasive particles and pressure-bearing requirements must be considered together.
Key Advantages
- Corrosion control: the nylon lining helps isolate compatible process media from the structural steel.
- Abrasion resistance: the nylon working layer is designed for suitable solids-containing fluids, slurry and tailings service.
- Flanged installation: supplied flange connections support bolt-on assembly without field welding at the pipe joint.
- Large-diameter capability: pipe sizes and spool lengths can be selected to suit the project layout.
- Lifecycle value: material selection can be evaluated against maintenance, replacement and shutdown costs, as well as initial purchase price.

Selection note: these figures describe the product range, not a guarantee that the maximum diameter, pressure and temperature can be combined. The allowable operating pressure at the design temperature, chemical compatibility and selected dimensions must be confirmed in the project quotation and drawings. Other pressure classes require separate engineering confirmation.
Applications and Medium Selection
Potential applications include oilfield produced-water and gathering systems, soda ash and salt-chemical process lines, and abrasive mineral slurry or tailings pipelines. Suitability depends on the complete operating conditions.
For alkalis, salt solutions, brine and selected weak-acid services, provide the medium composition, concentration and temperature for compatibility review. For mixed chemicals, gases, oxidizing media or cleaning fluids, include every component and the operating cycle in the assessment. Slurry selection also requires solids content, particle size and flow velocity.
Installation and Engineering Details
Flange standard, pressure class, gasket material, bolt requirements, pipe supports, thermal movement and external protection should be confirmed before installation. Matching the pipe rating to the mating flange and system design is part of the selection process. Follow the approved project drawings and installation instructions.
