Product Description
ASTM A269 PVC Covered 316L Stainless Steel Welded Multi - core Coiled Tubing
The 316L stainless steel welded multi-core coiled tubing developed by our company can be supplied conform to ASTM, DIN, KS and JIS standards. It is suitable for a variety of harsh climatic conditions and has a high safety factor and is widely used in remote control and monitoring systems such as shipbuilding, offshore platforms, petrochemicals, power generation, pneumatic. It has the advantages of one pipe multiplex control, easy wiring and convenient construction.
The stainless steel multi-core tube looks like a cable and is made up of two or more stainless steel seamless single-core tubes or welded single-core tubes.
The products are made of high quality stainless steel raw materials and jackets and fillers produced in accordance with ROHS environmental protection directives. It has the characteristics of pressure resistance, wear resistance, corrosion resistance, anti-aging, flame retardant and environmental protection.

Product Characteristics
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.
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.
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.
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.
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.
