1 / 8 * 0.028 Seamless Stainless Steel Coiled Control Line Tubing 316L

Seamless control lines are used in SCSSV, Chemical Injection, and Advanced Well Completions. Seamless tubes provide another tubing solution for our customer's complex well designs. The most common uses for Seamless line tend to be shorter length applications whereby no orbital welds are required.

316L stainless steel (UNS S31603) has been widely used in industry due to its excellent corrosion resistance. As one of the most commonly used coiled tubing materials, our 316L tube has mature technology and exquisite workmanship. Starting from the raw material, we strictly control the performance of steel. Our products meet ASTM A269 and all related industry standards. Our tubing is one continuous length of tubing, completely free of any welded joints or seams. Each coil is 100% hydrostatic tested. Eddy current testing (ET) is performed on the longitudinally seam welded tubing. Radiographic testing and ET are performed on material in the final heat treated condition. Yield pressure hydrostatic testing is performed on the heat treated tubing at final size.

Our products have complete specifications and can meet all working conditions. The outer diameter range of 316L control line tubing we supply is from 1/8" to 1". All dimensions and corresponding parameters are listed in the table below, we can also customize it according to customers' requirement details.

Hydrostatic test for each coil and conform to ASTM standards and requested specifications.

The specification and length per coil can be customized according to customer’s requirements.
