Product Description
3/8" OD Austenitic 316L Welded SS Stainless Steel Coiled Tubing
The 3/8" welded SS stainless steel coiled tubing is mainly used to inject chemicals into oil and gas wells. That is, the 3/8” austentic 316L welded SS stainless steel coiled tubing is connected to the downhole chemical injection valve, and the descaling is performed through the 3/8" welded SS stainless steel coiled tubing and the chemical injection valve. Chemical agent is injected from the surface into the oil tube at a certain depth down the well, which effectively removes the scaling of the oil tube and ensures the normal production of oil and gas fields.

It can also be used for pressure control of surface safety valves and other surface valves, and various connection tubelines of large-scale equipment instrumentation control systems for oil and gas field drilling and oil production.
Welded Control Lines are the preferred construction for lines being used in downhole oil and gas applications. Our 316L welded control lines are used in SCSSV, Chemical Injection, Advanced Well Completions, and Gauge Applications. We offer a variety of welded constructed lines. (Laser Welded, TIG Welded, welded and sunk drawn, welded floating plug drawn, and lines with enhancements) The various processes provide us the ability to customize a solution to meet your next well completion. Please contact our team to learn more about our welded control line offerings.

MANUFACTURING PROCESS AND RESULTANT PROPERTIES
The desired sizes are obtained by repeat cold drawing process, any welded joints are not
acceptable in each one coil ranging from 0.125 inch to 1 inch O.D. (3.2 mm to 25.4 mm) and a variety of wall thicknesses.
The strip is formed into a tubular cross section and longitudinally seam welded using either the gas tungsten arc (GTAW). The tubing may be welded at a larger outside diameter, sunk to final size and subsequently heat treated. Heat treated tubing is one continuous length of tubing, completely free of any welded joints or seams. Each coil is
100% hydrostatic tested.
NONDESTRUCTIVE TESTING (NDT)
Eddy current testing (ECT) is performed on the longitudinally seam welded tubing. Radiographic testing and ECT are performed on material in the final heat treated condition. Yield pressure hydrostatic testing is performed on the heat treated tubing at final size.
Packaging standard of 316L Welded SS Stainless Steel Coiled Tubing:
- Control line to be coiled on wooden drum and install protector to prevent from mechanical damage
- Customized packaging marking service
