Control lines are has very long continuous lengths coil, coiled tubing usually packed on coil wound on wooden drum or spool, also specific metal reels, Encapsulated and PVC coated are available.Zion Tube & Alloys - Stainless Steel Coil Tubes, Duplex Steel Tubes Manufacturer, Supplier, & Stockist in India The coiled tubes can be welded & redrawn tubes or seamless cold drawn tubes. Range of heat exchangers includes – Chilled Water Coils – Hot Water Coils – Direct Expansion (Evaporator) Coils – Condenser Coils – Steam Coils – Chilled Beam Coils – Active Beam Coils Control Line Coiled TubeĬoiled tubes for control line usually made of stainless steel, duplex stainless steel or nickel alloys, including stainless steel 316L, duplex 22, Nickel alloy 825 and alloy 625. Typical applications of stainless steel coil tubing: Mechanical structure with stainless steel coil tube applied for printing and dyeing, printing, textile machinery, medical equipment, kitchen equipment, automotive and marine accessories, construction and decoration. Industrial stainless steel tubing coil applied for heat exchangers, boilers, oil, chemicals, fertilizers, chemical fiber, pharmaceutical, nuclear power and so on.įluid stainless steel coil tube applied for beverages, beer, milk, water supply systems and medical equipment. Stainless Steel Coil Tubing For Heat ExchangerĬoil tubing is used for wide range of applications, applied for cooling and heating transferring energy in corrosive and non normal temperature environment, like food and beverage, oil and gas, medicine industry and so on, we manufacture and design coiled tubing to meet customer requirement in different sharps and purpose. Reduced installation labor costs-installing continuous length of tube takes less time and is more reliable than coupling multiple shorter lengths.Improved reliability-using fewer mechanical fittings or welds reduces the opportunity for defect, such as leaks and other long-term failures.Increased corrosion resistance, thanks to stainless steel, duplex and nickel alloys properties.Stainless steel tube is designed in coiling form, general small diameter, maximum tube length can be 1000 meters, without any joint metal, there are a large range sizes of stainless steel tubing for coiling, standard outside diameter is given below, and wall thickness ranges from 0.0275 inch – 0.083 inch, maximum length reach to 1000 meters.īWG gauge is usually defined wall thickness of tubing, checking more sizes. Standard Stainless Steel Coil Tubing Dimensions

We are a specialist in producing coil tubing, having the expertise and techniques to meet tubing bend service, all the tubing is conducted in 100% tested at the appropriate pressure, tubing inner and outer surface is clean and try for packing.Īfter annealing, straighten stainless steel tubing is in soft condition, tubing can be bent, formed and fabricated in various directions and angles, small diameter and thin wall coil tubing are available for special application. Stainless Steel Coil Tubing Specifications

UK, USA, Canada and South Africa are main markets for our stainless steel coil tubing.

and wall thickness from 0.035 to 0.065 in., we are capable of producing long lengths of stainless tubing in coils, for some tubing sizes, we are able to achieve coils that even up to 2000 m in length without any longitudinal or orbital welds.ĪSTM A213 / A269 standard specification is applied for seamless stainless steel tubing, ASTM A249 / A269 for welded tube, with both bright annealing finish and annealing pickling finish, generally, seamless coil tubing can be provided in no risk of impurities that are often associated with welding tube, seamless tubing is the preferred option for critical applications. DONGSHANG stainless has many year of experience to offer stainless steel coil tubing with sizes from 1/4 to 1 in.
