Specialized Metallurgy
Expertise Across 5 Industrial Pipe Materials
Pipeline transmission requires specific jointing technologies, alignment tolerances, and bed preparation depending on metallurgy and fluid dynamics. CIP operates trained technicians for each pipe system.
Glass Reinforced Plastic
High corrosion resistance and hydraulic smoothness; lightweight yet structurally durable under subterranean pressure.
Typical Applications:
Bulk potable water transmission, sewerage networks, and industrial chemical/effluent pipelines.
High-Density Polyethylene
Flexible, impact-resistant piping with fused leak-proof jointing via electrofusion and butt-welding techniques.
Typical Applications:
Urban water distribution, effluent conveying, and trenchless/cross-country routing.
Ductile Iron
Superior tensile strength, high pressure resistance, and proven durability with push-on or mechanical flexible jointing.
Typical Applications:
High-pressure municipal potable water mains, pumping transmission mains, and urban distribution.
Mild Steel
Heavy structural integrity, high impact tolerance, and custom field-fabrication flexibility with circumferential welding.
Typical Applications:
Large-diameter water mains, canal/river bridge crossings, and plant utility infrastructure.
Carbon Steel
Engineered for high-temperature and high-pressure duties with stringent radiographic testing standards.
Typical Applications:
Petrochemical refinery utility corridors, thermal power plant piping, and process steam/fuel lines.
Hydrostatic Testing & Commissioning
Every pipeline section executed by CIP undergoes rigorous hydrostatic pressure testing, weld radiography, joint deflection checks, and flushing prior to final client handover.
