Setting the Global Standard in Industrial Fluid Transport

As a leader in the metal products industry, our pu lined pipeline systems represent the pinnacle of material synergy. We integrate high-strength carbon steel with a precision-extruded polyurethane inner layer, ensuring unmatched longevity in the most aggressive environments.

Our technical advantage lies in the seamless bonding technology that prevents lining collapse under vacuum conditions. By utilizing medical-grade PU polymers, these pipelines offer superior abrasion resistance and chemical stability, drastically reducing maintenance costs for industrial operators.

The Core Pillars of
Pipeline Excellence

Our manufacturing process is built upon three fundamental technical disciplines to ensure reliability.

Advanced Polymer Science

Utilizing high-density TPU and specialized polyurethane blends for interior lining.

  • Abrasion Index: 5x higher than standard rubber linings.
  • Elastic Modulus: Optimized for thermal expansion.
  • Chemical Resistance: Stable against oils and mild acids.

Structural Steel Precision

Using high-grade alloy steel for the outer shell to provide maximum pressure support.

  • Wall Thickness: CNC controlled to ±0.1mm accuracy.
  • Corrosion Coating: Exterior epoxy powder finish.
  • Joint Welding: Full-penetration robotic TIG welding.

Co-Extrusion Mastery

Proprietary lining process ensuring an airtight bond between metal and PU.

  • Dynamic Pressure Testing: Every pipe tested at 1.5x rated pressure.
  • Ultrasonic Inspection: Ensuring zero voids in the lining.
  • Tolerances: Precise inner diameter for optimized flow.

Frequently Asked
Questions

Expert answers to common technical and commercial inquiries.

1

What are the main benefits of a pu lined pipeline?

The primary benefit is the combination of metal's structural strength and polyurethane's extreme abrasion and corrosion resistance, significantly extending the pipe's lifespan compared to bare steel.

2

How do you ensure the lining doesn't peel off?

We use a proprietary co-extrusion and thermal bonding process that creates a chemical bond between the steel surface and the PU, preventing delamination even under vacuum.

3

What is the maximum operating pressure?

Pressure limits vary by pipe diameter and wall thickness, typically ranging from 6 MPa to 16 MPa. We provide specific pressure ratings for every custom order.

4

Can the PU lining be customized for hardness?

Yes, we offer a range of hardness from Shore 80A (more flexible) to 98A (extreme wear resistance) depending on the particulate size in your fluid.

5

How long is the typical lead time for custom orders?

Standard lead times are typically 2-4 weeks, while custom high-spec pipelines may take 6-8 weeks depending on the quantity and material requirements.

6

Do you provide installation guidance?

Yes, we provide detailed technical manuals for welding and jointing PU lined pipes to ensure the internal lining remains continuous and secure.
