Water treatment facilities demand piping solutions that resist corrosion, maintain purity, and withstand constant exposure to aggressive chemicals and variable pressures. Our comprehensive inventory covers every requirement, from water processing stainless welded steel tube to welded stainless pipe for water purification, each engineered for longevity in demanding environments. The aquatic treatment stainless welded conduit series integrates seamlessly with existing infrastructure, while our water system stainless steel welded tube lineup meets stringent industry codes. These products deliver consistent performance in reverse osmosis, deionization, and wastewater recycling operations, minimizing contamination risks and maintenance downtime. With a focus on smooth interior surfaces that inhibit biofilm formation, the tubing ensures high flow rates and energy efficiency. Certified welds and rigorous hydrostatic testing guarantee structural integrity, while optional electropolishing enhances cleanability for ultrapure water applications. Municipal water plants, pharmaceutical producers, and food and beverage processors all benefit from the reliability of this welded stainless steel technology.
Water Treatment Grade Stainless Steel Tubing is available in multiple grades and dimensional configurations to match precise system specifications. The manufacturing process utilizes longitudinal welding with full-bead penetration, followed by solution annealing to restore corrosion resistance and normalize the heat-affected zone. Below is a detailed breakdown of key product parameters.
| Nominal Size (inch) | OD × Wall (inch) | Working Pressure @RT (psi) | Surface Ra (μin) |
|---|---|---|---|
| ½ | 0.840 × 0.109 | 2850 | <30 (EP option) |
| 1 | 1.315 × 0.133 | 2200 | <30 (EP option) |
| 2 | 2.375 × 0.154 | 1880 | <32 (EP option) |
| 3 | 3.500 × 0.216 | 1800 | <32 (EP option) |
| 4 | 4.500 × 0.237 | 1650 | <35 (EP option) |
| 6 | 6.625 × 0.280 | 1500 | <35 (EP option) |
Every length of Water Treatment Grade Stainless Steel Tubing undergoes eddy current or ultrasonic testing to detect longitudinal defects, and weld seams are examined via radiographic inspection for critical applications. Packaging includes plastic end caps and weather-resistant crating to prevent contamination during transit. For high-purity loops, supplementary documentation such as material test reports, positive material identification, and surface roughness certifications are supplied as standard. The tubing integrates with compression, orbital welding, and clamp-style fittings, providing flexibility from small-diameter lab connections up to large municipal distribution headers.
