The red-painted steel pipe shown above is widely used in the sprinkler pipe system to ensure long-term corrosion resistance and compliance with international fire protection standards. Each pipe undergoes precise grooving and threading processes for easy connection and leak-free performance.

Key Features

Durable Construction: Fabricated from high-grade black or galvanized steel, PVC, and CPVC to handle high pressure in fire protection systems.
Surface Options: Red coating, hot-dip galvanizing, or black finish available to suit indoor and outdoor conditions.
System Compatibility: Suitable for wet pipe fire sprinkler systems, dry pipe fire sprinkler systems, and underground sprinkler pipe connections.
Easy Installation: Grooved ends can be quickly assembled with mechanical couplings, eliminating the need for on-site welding.
Leak-Free: Precision-machined grooves ensure tight sealing and stable performance under pressure.
Custom Lengths & Sizes: Available in sizes from 1” to 12” (DN25–DN300) with custom wall thickness and end treatment.

Applications

Firefighting systems in commercial, residential, and industrial buildings
Underground sprinkler pipe for water supply
Retrofitting and maintenance projects, including how to fix a broken sprinkler pipe situation
Combined steel and plastic fire sprinkler pipe systems for mixed environments

Manufacturing & Quality Control

The production process involves grooving, threading, and coating, all under strict ISO and UL/FM quality control. Each fire pipe is inspected for wall thickness, groove accuracy, and coating adhesion to ensure performance reliability in demanding environments.
