Tiptop offers 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.
Duplex 2205 Stainless Steel Coiled Control Line Tubing Features
Close dimensional tolerances
Enhanced mechanical properties
Superior surface finish
High cleanness of inside surface
Controlled ovality, eccentricity
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.
Welded Control Lines are the preferred construction for lines being used in downhole oil and gas applications. Our welded control lines are used in SCSSV, Chemical Injection, Advanced Well Completions, and Gauge Applications.
Application:
Down hole tubes
Subsea umbilical’s
Process constructions
General control system
Steam supply lines
Gas transport lines
Instrumentation
