The multi-core tube consists of one to nine stainless steel tubes laid up spirally inside an extruded outer PVC sheath. They are widely used for pneumatic and hydraulic remote control, measuring and monitoring systems. Materials are ASTM TP316/ 316L, TP304/304L. Each individual tube is PVC sheathed in a different color for easy identification and protection purposes . The extruded outer sheath is made of oil and seawater resistant, weatherproof, flame retardant, corrosion and acid resistant PVC. The multi-core tube is continuously marked at every one meter throughout the entire length for easy installation. Heat shrinkable products provide complete water sealing, abrasion and corrosion protection under all conditions.
The products are made of high quality stainless steel raw materials and jackets and fillers produced in accordance with ROHS environmental protection directives.lt has the characteristics of pressure resistance, wear resistance, corrosion resistance, anti-aging, flame retardant and environmental protection. It is suitable for a variety of harsh climatic conditions and has a high ety factor.
