Standard 4 Inch GI Pipe, Class B, 6m Length

4 Inch GI Pipe

The Standard 4 Inch GI Pipe provides a robust solution for high-volume water distribution and structural applications. This hot-dip galvanized steel conduit meets Class B (Medium) specifications for durability and pressure resistance. It serves as a primary component in municipal water lines and industrial plumbing networks.

Built for the Job

Contractors utilize this material for main risers and heavy-duty water supply lines in commercial developments. The 4-inch nominal diameter supports high flow rates required for fire protection systems and irrigation mains. Site supervisors prefer galvanized iron for its superior mechanical strength compared to plastic alternatives. This pipe withstands external impacts and high internal pressures common in multi-story building infrastructures. The zinc coating ensures the steel remains protected against oxidation in damp environments or outdoor installations.

• Installation of main water supply lines in industrial facilities.

• Fabrication of heavy-duty structural supports and handrails.

• Firefighting hydrant systems and sprinkler main headers.

Product Highlights

Corrosion Resistance

Hot-dip galvanization provides a resilient barrier against rust and chemical degradation.

Mechanical Integrity

• Class B wall thickness ensures structural stability under load.
• High tensile strength steel prevents sagging over long horizontal spans.

Technical Specifications

What’s Included

On-Site & Workshop Notes

• Always use a heavy-duty pipe wrench for securing 4-inch fittings to ensure leak-proof joints.

• Apply industrial-grade thread sealant or PTFE tape to all male threads before assembly.

• Store the galvanized sections on elevated racks to prevent direct contact with wet soil.

• Treat any site-cut ends with cold galvanizing spray to maintain the protective zinc layer.

• Verify that the Class B rating matches the maximum working pressure of your specific pump system.
