Grooved Steel Pipe for Water Supply & Fire Protection Systems

Our grooved steel pipes are specifically designed for rapid connection in fire sprinkler systems and water supply networks. Manufactured in accordance with global standards like ASTM A53, BS 1387, and DIN EN 10217, these pipes feature precision-engineered grooved ends that ensure leak-proof performance and structural stability. Whether you require red-painted pipes for fire protection or hot-dipped galvanized pipes for fluid transport, our products offer high-pressure resistance and superior anti-corrosion properties.

Professional Product Features

Precision Grooving Technology: Our grooved ends are processed using automated equipment to ensure precise depth and width. This allows for seamless compatibility with standard mechanical couplings, significantly reducing installation time and labor costs on-site.
100% Hydrostatic Safety: Every length of our fire protection pipe undergoes a 100% hydro-test. This rigorous pressure testing ensures the integrity of the pipe under the high-pressure conditions required for fire safety and fluid delivery systems.
Superior Anti-Corrosion Protection: For fire protection, we provide high-grade red painting that resists flaking and oxidation. For water systems, our hot-dipped galvanization provides a thick zinc layer that protects both the internal and external surfaces from rust.
High-Strength Materials: Utilizing materials like Q345 and S355JOH, our pipes provide the structural strength necessary for industrial infrastructure, while remaining cost-effective for commercial building projects.

Product Applications

Fire Protection: Main supply lines and branch lines for automatic fire sprinkler systems.
Potable & Waste Water: Reliable piping for municipal and industrial water transportation.
HVAC Systems: Chilled water and heating system piping where mechanical grooved joints are preferred.
Mining & Industrial: Fluid transport in environments where quick assembly and disassembly are required.

Packaging & Delivery

Packaging: Seaworthy bundles secured with steel strips. For painted pipes, we offer additional damp-proof wrapping to protect the finish during transit.
Port of Shipment: Xingang Port, Tianjin, China.
Lead Time: Efficient production and logistics, normally 18-20 days after payment confirmation.
Payment Options: L/C, T/T, D/P, O/A.

Frequently Asked Questions (FAQ)

Q: Why use grooved ends instead of threaded or welded ends?
A: Grooved pipe joints are faster to install, allow for thermal expansion/contraction, and provide a vibration-dampening connection compared to rigid welding or threading.

A: Yes, our grooved ends are manufactured strictly to international standards to ensure 100% compatibility with global coupling brands (e.g., Victaulic style).

A: Yes. We have a professional QC team and support third-party testing such as SGS or BV to verify pressure ratings and material compliance.

A: Yes. Our hot-dipped galvanized grooved pipes are ideal for dry systems to prevent internal corrosion, while painted pipes are widely used for wet systems.

A: Yes, we provide free samples for quality and grooving precision checks.
