Engineered for Century-Span Water Conveyance
Water is the lifeline of civilization. In long-distance water diversion, municipal distribution networks, industrial recirculating systems, and high-pressure transmission mains, pipe reliability is the single most critical factor determining project safety and service life.
merits
Full-size precision with defect-free internals
Produced via advanced piercing + cold-rolled/hot-rolled processes, the internal and external surfaces are smooth, free from scars, laps, or folds. This reduces hydraulic friction losses, cuts pumping energy costs, and inherently prevents sediment buildup and biofilm formation.
01
Superior pressure endurance with built-in safety margins
The absence of welded seams eliminates the weakest link. Yield and tensile strengths significantly exceed those of equivalent welded pipes, providing reliable resistance against water hammer, surge pressures, and differential settlement stresses.
02
Dual protection – material integrity plus advanced coating
Tight control over chemical composition (low S & low P), combined with optional internal linings (epoxy, cement mortar) and external 3PE/FBE coatings, ensures compatibility with raw water, potable water, and reclaimed water across a wide pH range. Design life exceeds 50 years.
03
100% rigorous inspection regime
Manufactured to ASTM A106 standards. Every pipe undergoes hydrostatic testing, ultrasonic flaw detection, and eddy current inspection – ensuring zero-defect delivery.
04
Applications
Long-distance inter-basin water diversion projects (e.g., South-to-North Water Transfer supporting systems)
Industrial cooling water and process water lines for power plants & chemical facilities
High-pressure pumping stations and gravity-flow systems with significant head drops
