Multi Core Stainless Tubing

The multicore stainless steel tubse consists of one to nine stainless steel, copper or copper-alloy tubes laid up spirally inside an extruded outer PVC sheath. For easy identification and protection purpose, each individual tube is PVC sheathed in a different color. The extruded outer sheath is made of oil and seawater resistant, weatherproof, flame retardant, corrosion and acid resistant PVC.

 Product Characteristics1. Easy to lay, labor saving

Multi-core tube is easy to take shape like cables, the operating tools are simple and it is convenient for laying. Mark can be made meter by meter. Each tube has PVC sheath with different colors, which is easy to identify.

2. Superior performance, free of maintenance

Multi-core tube adopts high quality stainless steel strip and outer sheath raw materials produced according to ROHS environmental protection directives, so it is pressure resistant, wear resistant, water and oil-proof, corrosion resistant and aging resistant and can adapt to various complicated climate conditions. It has high thermal resistance, small heat waste and high safety factors, so it will not cause scalding.

3. Customized to avoid waste

Single ultra-long tube can be manufactured based on fixed dimension and multi-core cables can also be manufactured to form one tube and multi-circuit control, thus saving expensive joint and accessories expenses.

4. Positioned as high quality products to ensure absolutely safe

By using high quality raw materials, automatic production process, strict process control and testing means, the hidden trouble of quality can be effectively eliminated.

5. High-tech technology and extensive applications

Multi-core tube is safe, reliable; convenient for laying; occupies little space, easy to configure and convenient for management. It is particularly suitable for pneumatic and hydraulic control system as well as measuring and monitoring system, etc in the shipbuilding, oil and gas, hydraulic, chemical and other industries.

Stainless Steel Seamless Multi - core Coiled Tubing with 6 Cores

The multicore tube consists of one to nine stainless steel, copper or copper-alloy tubes laid up spirally inside an extruded outer PVC sheath. For easy identification and protection purpose, each individual tube is PVC sheathed in a different color.
