3/8 Duplex 2507 Seamless Stainless Steel Coils
3 / 8 * 0.035 Seamless Stainless Steel Coiled Control Line Tubing Duplex 2507
Tiptop is specialized in providing a variety of duplex stainless steel, super duplex stainless steel welded and seamless tubing, depending upon the properties the tubing is required to exhibit. Other alloys and sizes are also available upon request. Duplex stainless steels (named for their austenite and ferrite compositions), has greater yield strength than austenitic stainless steel.
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.
Standard: ASTM-A 789 Standard specification for seamless and welded ferretic/austenitic stainless steel tubing for general service. This specification covers various grades of duplex stainless steels.
