ASTM A269 TP316L Stainless Steel BA Coil Tube used in Oil and Gas

ASTM A269 TP316L Stainless Steel BA Coil Tube Manufacturer

We are a professional manufacturer of ASTM A269 tp316/316L coil tubing Coiled Tubes in China.

​​SA269 Gr 316 tubes are widely used in various pressure vessel ratings. They are very robust and protect piping from stress-induced pitting and crevice corrosion in equipment.​​

​​SS 316 seamless coiled tubing is also commonly used in operations. Compared to wireline-run casing, its primary advantages lie in the ability to pump chemicals through the coil and push it into the hole without relying on gravity. 316 SS coiled tubing eliminates the need for connection fittings to complete long-distance pipeline installations. This not only shortens installation time and reduces costs but also eliminates potential leak points.​​

​​316 stainless steel coil is highly suitable for unit heaters, boiler air preheating, condensing and cooling, as well as high-pressure, air tempering, dryers, and similar applications. The characteristics of coil heat exchangers include flexibility, low pressure drop, and high efficiency.​
