Overview:
TP316L coil tubes are a type of stainless steel tubing well-regarded for their exceptional corrosion resistance and versatility in various applications. Made from low carbon content 316 stainless steel, they exhibit improved weldability and reduced sensitization, which is crucial in environments prone to intergranular corrosion.
These coil tubes are often used in industries such as chemical processing, oil and gas, power generation, and pharmaceuticals, where robust performance is required at elevated temperatures and exposure to harsh conditions. Their ability to withstand a wide range of chemicals makes them ideal for transporting fluids in demanding environments.
In terms of physical properties, TP316L features a good balance of strength and ductility, allowing for complex shaping and bending without compromising integrity. Their smooth surface finish enhances flow characteristics, reducing friction and potential for corrosion build-up.
