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.

Outer Diameter (OD): 3 mm (0.118”) to 25.4 mm (1.00”)

Wall Thickness (WT): 0.5mm (0.020”) to 3mm (0.118”)

OD tolerance: +/- 0.005” (0.13mm) , other tolerances are available on request

WT tolerance: +/- 10%, other tolerances are available on request

Tubing Coil lengths up to 6,000m (20,000ft) without orbital joints depending on product dimensions and its form (seamless tube or welded tube).

Coil lengths up to 13,500m (45,000ft) with orbital joints

The most popular size of control lines are: 1/4″ control line, 3/8″ control line, 1/2″ control lines, 5/8″ control line tubes, 3/4″ control line tubing.

With the leading direction of producing High pressure extra long stainless steel control line tube(stainless steel coiled tubes), TIPTOP has become a high-tech industrial company integrating domestic research and development, production and sales. The company successfully developed a series of stainless steel testing cables in 2000. In recent years, the company has been committed to the research and development of duplex steel and nickel alloy control lines, and has been widely approved in the international market.

The company covers an area of 20,000 square meters and a building area of 12,000 square meters. The company has several stainless steel tube production lines, tube making units, tube drawing units, well-type electric furnaces, online vacuum light furnaces and other production equipment. The company also has a quality inspection center that meets the national stainless steel tube quality inspection requirements. The quality inspection center has a 300Mpa hydraulic test machine, tensile test bench, Vickers hardness tester, 500°C temperature resistance test furnace, eddy current flaw detector and a series of stainless steel products. Testing and inspection equipment to ensure the reliability and stability of the chemical and physical properties of stainless steel products.　

The company annually produces more than 3,000 tons of stainless steel control lines and other products, sales marked covers both domestic and overseas, for domestic, we are network-enterprise company of CNOOC, Petro China and Sinopec, as for international,it has been widely used in Middle East, Southeast Asia, South America, Australia and so on.　

On the premise of improving the quality of its own brand products, the company has continuously increased the research and development of new products, and has cooperated and actively invested with many domestic universities and scientific research institutions. In recent years, the company has passed the certifications of CCS, GL, DNV and other classification societies.
