Manufactures & Suppliers of Pipes, Tubes, Flanges, Pipe Fitting & Fasteners

Stainless Steel Coil Tubing is a long, continuous length of metal tubing, typically ranging in size from 1 inch to 3.25 inches in diameter. It is supplied in large coiled spools and is used in a wide variety of industrial applications. Stainless Steel Coiled Tubing is highly regarded for its excellent corrosion resistance and is often utilized in drilling, oil field piping systems, and other environments where the tubing undergoes significant stress. These systems demand robust materials, and coiled tubing is ideal for such high-stress applications. In systems like heat exchangers, Stainless Steel Coil Tubing Heat Exchangers are known for their strength, performing effectively in high-temperature and high-pressure environments. Smaller-diameter coiled tubing is typically installed using coil straighteners for smooth application.

Stainless Steel Coiled Tubing, Stainless Steel Coil Tubing Heat Exchangers, Stainless Steel 304 Coiled Tube and 316 SS Coil Pipe, SS Coiled Tubing, Stainless Steel 316 Coil Tubing

At Natron Steel, we manufacture coiled tubing in popular stainless steel grades such as 304 and 316. 316 Stainless Steel Coiled Tubing is commonly used for applications that involve pumping chemicals or oil directly into a hole without relying on gravity. This versatile tubing showcases excellent chemical resistance and enhanced tolerance to reducing oxidants and corrosive media, making it perfect for harsh environments. On the other hand, 304 Stainless Steel Coiled Tubing offers a cost-effective alternative that performs well in various industrial operations, particularly in drilling and hole mining applications.
