ASTM A269 S316L PVC Coated Stainless Steel Coiled Tubing is a corrosion-resistant, cold-formed austenitic stainless steel tube designed for continuous water supply lines where long coil length, clean internal flow, external abrasion protection, and chloride resistance are required.
The core tube is ASTM A269 TP316L / UNS S31603 stainless steel, supplied in heat-treated condition. The external PVC layer adds physical protection against abrasion, atmospheric exposure, and galvanic contact while keeping the 316L stainless steel bore suitable for water transmission.
| Item | Description |
|---|---|
| Material | Austenitic stainless steel tube with external PVC coating |
| Main Standard | ASTM A269 / A269M |
| Grade | S316L / TP316L / UNS S31603 |
| Tube Type | Seamless or welded coiled tubing; seamless preferred for high-integrity water lines |
| Outer Diameter | Commonly 3 mm-32 mm; custom sizes available |
| Wall Thickness | Commonly 0.3 mm-3.0 mm; selected by pressure and bending radius |
| Length | 1-12 m straight length available; long coils can be supplied as project-specific spools |
| Tolerance Range | OD and WT per ASTM A269; tighter tolerances available by agreement |
| Surface Condition | Bright annealed, pickled, passivated, or polished stainless core; external PVC coated |
| Feature | Technical Value |
|---|---|
| Low-carbon 316L chemistry | Carbon is limited for TP316L, reducing sensitization risk after welding and improving resistance to intergranular corrosion. |
| Molybdenum-bearing stainless core | TP316L contains approximately 2.00-3.00% Mo, giving better pitting and crevice-corrosion resistance than 304-series stainless steels in chloride-bearing water. |
| Heat-treated ASTM A269 tube | ASTM A269 requires tubing to be furnished in heat-treated condition and to meet hardness and verification test requirements. |
| PVC external protection | The PVC layer helps reduce abrasion damage, atmospheric corrosion influence, and metal-to-metal galvanic contact during installation. |
| Coiled delivery | Fewer joints are needed compared with short straight pipes, reducing potential leakage points in water supply routing. |
| Professional Concern | Practical Solution |
|---|---|
| "Will the tubing resist chloride-related corrosion in water supply systems?" | We use ASTM A269 TP316L / UNS S31603 as the base material. Its 16-18% Cr, 10-15% Ni, and 2-3% Mo composition supports better chloride pitting resistance than 304-type stainless steel. |
| "Will the tube be verified before shipment?" | Each production lot can be supplied with material test reports covering chemistry, heat treatment, hardness, dimensions, and hydrostatic or nondestructive electric testing in line with ASTM A269 requirements. |
| "Can the coating survive installation handling?" | The PVC jacket is specified as an external protective layer to reduce abrasion, galvanic contact, and atmospheric exposure during routing, bundling, and installation. |
