Our Solvent-Free Polyurethane Coated Steel Pipe is an advanced anti-corrosion pipeline product that uses environmentally friendly, high-performance polyurethane coating technology to provide excellent corrosion protection, chemical resistance, and mechanical strength.

Unlike traditional solvent-based coatings, the 100% solvent-free polyurethane coating system contains no volatile organic compounds (VOC), providing better environmental performance, stronger adhesion, and safer application.

The product combines the high strength of steel pipe with the excellent protective properties of polyurethane coating, making it ideal for water transmission pipelines, drinking water projects, oil & gas transportation, chemical pipelines, marine engineering, and industrial fluid systems.

With advanced coating equipment and strict quality control, we provide reliable anti-corrosion pipeline solutions for global infrastructure projects.

The polyurethane coating system mainly includes:

1. **Steel Pipe Base Layer**

High-strength carbon steel provides excellent structural stability and pressure resistance.

2. **Surface Treatment Layer**

Steel surface is cleaned by professional blasting treatment to achieve excellent coating adhesion.

3. **Solvent-Free Polyurethane Coating Layer**

The polyurethane coating provides:

Our Socket Steel Pipe is specially designed for water transmission, municipal water supply, irrigation systems, water conservancy projects, and underground pipeline networks. Compared with conventional welded connections, socket joint steel pipes provide faster installation, better alignment, excellent sealing performance, and lower installation costs.

We manufacture large-diameter socket steel pipes from DN200 to DN1600 (200–1600 mm) with two connection systems to meet different engineering requirements:

- Spherical Lap Weld Socket Joint (Ball Socket Welded Connection)

- T-Type Rubber Ring Flexible Joint (T-Type Push-on Joint)

Manufactured using high-quality carbon steel and advanced welding technology, our products comply with international quality standards and are widely used in municipal infrastructure, water treatment plants, pumping stations, industrial pipelines, and long-distance water transmission projects.

Our Socket Steel Pipes are widely used in:

- Municipal Water Supply Networks

- Water Conservancy Projects

- Irrigation Systems

- Water Treatment Plants

- Pumping Stations

- Industrial Water Pipelines

- Fire Protection Systems

- Urban Infrastructure

- Long-Distance Water Transmission

- Mining Water Supply

- Power Plant Cooling Water Systems

Our Steel Pipe Piles are manufactured using high-quality carbon steel with advanced submerged arc welding technology to provide superior strength, durability, and load-bearing performance.

With excellent axial compression resistance, bending performance, and corrosion protection options, our steel pipe piles are an ideal foundation solution for demanding geotechnical and civil engineering applications.

As a professional steel pipe manufacturer, we provide customized piling solutions for EPC contractors, foundation engineering companies, and infrastructure projects worldwide.
