Seamless Cold Drawn 316L Multi Core Tubing For Chemical Injection
Multi-core tube by a 1-9 stainless steel tube, stainless steel tube which is placed on the outer helical PVC jacket extruded. In order to facilitate the identification and protection, each of the individual tubes are wrapped by different colored PVC jacket. Extruded by the oil jacket and water resistant, weather resistant, flame retardant, corrosion-resistant and acid-resistant PVC. Multi-core tube (outer) mark once every one meter continuously over the entire length, to facilitate installation. Heat shrinkable products provide a complete waterproof, wear and corrosion protection in all conditions.
Materials are ASTM TP316/ 316L, TP304/304L.
