Cold Drawn ASTM Seamless Stainless Steel Coils

ASTM Standard Seamless Steel Control Line Tubings for oil & gas application

Tiptop is a global supplier of hydraulic control lines, we offer a variety of stainless steel, duplex stainless steel, nickel, monel, and super austenitic welded and seamless tubing, depending upon the properties the tubing is required to exhibit. Other alloys and sizes available upon request. Stainless steels exhibit excellent forming and welding characteristics, while duplex stainless steels named for their austenite and ferrite compositions, has greater yield strength than austenitic stainless steel. Nickel alloys have high corrosion resistance and temperature strength, while super-austenitic alloys were designed to resist crevice corrosion, pitting, chloride-induced corrosion, and stress corrosion cracking. We can also offer the encapsulation of control lines to provide increased durability along with chemical and corrosion resistance. To meet each project's specialized requirements, we have developed two primary jacketed

tubing. F46 Encapsulated Control Line and Nylon Encapsulated Tubing

Your choice will depend on your process environment and your requirements. We

can help you arrive at the most cost-effective solution for your needs.

Seamless control lines are used in SCSSV, Chemical Injection, and Advanced Well Completions. Seamless tubes provide another tubing solution for our customers' complex well designs. The most common uses for Seamless line tend to be shorter length applications whereby no orbital welds are required. Please contact our team to learn more about our seamless control line offerings.

As one of the leading China control line supplier, Tiptop produces full range of the popular control line sizes. Our control line tubing can be supplied in metric size and imperial size.
