Coated Steel Fire Protection Pipes

As a new generation of dedicated fire-fighting pipes, Durable Coated Steel Fire Protection Pipes use high-quality steel as the base material; we have 4 production lines and fully automated grooving machines, and offer free grooving services. Furthermore, Juming has introduced advanced sandblasting equipment to ensure the adhesion of every steel pipe.

Featuring a dual-layer coating process—an inner layer of epoxy resin for corrosion resistance and an outer layer of fire-resistant coating—our pipes offer exceptional strength, corrosion resistance, impact resistance, and fire protection. Ideal for building fire water supply, sprinkler systems, and emergency escape channels, our products meet GB/T 28897-2012 (“Coated Steel Water Supply Pipes”) and GB 5135.1-2019 (“Automatic Sprinkler Systems – Part 1: Sprinkler Heads”) standards, providing long-lasting safety for your projects.

Our products are reliable and durable, and are ready to meet your fire protection project needs.

What are the main advantages of our products?

1. Dual Protection for Enhanced Safety

Inner Anti-Corrosion Layer: Food-grade epoxy resin coating resists acid and alkali corrosion, preventing rust and blockages. Ensures a service life of over 30 years.

Outer Fire-Resistant Layer: High-temperature flame-retardant coating withstands temperatures over 1000°C, maintaining pipe integrity for more than 180 minutes during fire emergencies, providing critical time for evacuation.

2. High-Strength Steel for Maximum Load Capacity

Quality Coated steel fire protection pipes are made of high-quality Q235B low-carbon steel with a yield strength of ≥235MPa and a pressure resistance of up to 2.5MPa, making them suitable for high-rise buildings, underground projects, and other harsh environments.

Smooth inner wall reduces water resistance, enhancing the response speed of firefighting systems.

3. Easy Installation to Reduce Costs

Supports grooved and flange connections without on-site welding, reducing installation time by up to 50%.

40% lighter than traditional cast iron pipes, lowering transportation and lifting costs, ideal for tight spaces.

4. Versatile and All-Scenario Applicable

Pipe sizes: DN15–DN300 to meet various flow requirements.

Applicable environments: Suitable for indoor and outdoor use, moisture-resistant, UV-resistant, and ideal for commercial buildings, industrial facilities, and municipal projects.
