Product introduction
Product Description
ERW Carbon Steel Pipe For Water Supply 76mm is a standard high-frequency electric resistance welded steel pipe specially designed for municipal and domestic water supply engineering. Adopting advanced ERW straight seam welding technology, this 76mm small-diameter water pipe features uniform wall thickness, smooth inner and outer pipe walls, low water flow resistance and excellent overall structural stability. It is widely used for residential water delivery, building water supply, municipal branch water pipes and general industrial circulating water transmission.
All 76mm water supply steel pipes are produced in strict accordance with GB/T 3091, ASTM A53 and other fluid pipeline standards. Each pipe undergoes 100% hydrostatic pressure test and weld non-destructive inspection to ensure no leakage, stable pressure resistance and long-term safe water delivery performance. As a universal conventional specification for water supply projects, 76mm ERW steel pipe has complete matching accessories, convenient construction and ultra-high cost performance, becoming the preferred pipe for small and medium-caliber water supply pipeline systems.

Core Product Advantages
Excellent Weld Quality & Zero Leakage
Adopting precision high-frequency ERW welding technology, the weld seam is perfectly integrated with the pipe body without cracks, gaps or slag inclusions. Every 76mm water supply pipe passes strict hydrostatic pressure testing and weld flaw detection, effectively eliminating water leakage risks and ensuring long-term safe and stable operation of water supply pipelines.
Smooth Inner Wall & Efficient Water Delivery
The inner wall of the pipe is smooth and burr-free, which greatly reduces water flow friction and avoids sediment adhesion and pipeline blockage. It ensures stable water flow and uniform water pressure, effectively improving water supply efficiency and reducing daily water delivery energy consumption, very suitable for long-term domestic and industrial water supply.
Standard 76mm Universal Matching Size
76mm outer diameter is a mainstream conventional specification for small-diameter water supply pipelines, which is fully compatible with all standard elbows, tees, flanges, valves and pipe fittings on the market. It features strong versatility, convenient on-site docking and high construction efficiency, saving project supporting costs and construction cycle.
Stable Structural & Pressure Resistance
Made of high-quality Q235B/Q355B/L245 carbon steel, the pipe body has uniform structure, good toughness and compression resistance. It can adapt to buried and exposed laying environments, resist external soil pressure and construction impact, and maintain structural stability in long-term water supply operation.
High Cost Performance for Water Projects
Compared with seamless steel pipes, ERW welded pipes have lower procurement costs while fully meeting water supply pressure and safety standards. With stable quality, low failure rate and almost no later maintenance cost, it is the most cost-effective choice for municipal water renovation, community water supply and factory water supply projects.
