Municipal water supply, raw water transfer, and industrial cooling water systems — AWWA C200 compliant steel pipe with cement mortar lining and advanced external coatings for 50+ years of reliable service.
Water is the world's most critical resource, and the infrastructure that transports it must be reliable, durable, and cost-effective. Sino East Steel provides complete steel pipe solutions for every water transmission application — from large-diameter municipal supply mains to industrial cooling water systems and raw water transfer lines. Our steel pipe is manufactured to AWWA, ISO, and EN standards with a full range of internal linings and external coatings.
Municipal water transmission mains demand large diameters, long service life, and absolute reliability. Our AWWA C200-compliant spiral welded steel pipe with cement mortar lining (AWWA C205) delivers the flow capacity, structural strength, and corrosion resistance needed for city water supply networks serving millions of people. Diameters up to 120 inches accommodate the highest-volume requirements.
Long-distance raw water transfer projects — from reservoirs to treatment plants or between basins — require economical, large-diameter pipe with proven long-term performance. SSAW steel pipe offers the best cost-to-performance ratio for these applications, with lower installed cost than ductile iron or concrete alternatives for diameters above 24 inches.
Power plants, refineries, and industrial facilities require massive volumes of cooling water. Our steel pipe systems handle the full range of cooling water applications: once-through systems, recirculating cooling loops, and make-up water supply lines. Special coatings are available for brackish water and seawater cooling applications.
