ASTM A789 Duplex 2507 Hydraulic Control Line 1 / 8 * 0.035 Seamless Tubing

Chemical Composition

Size Chart:

Hydrostatic test for each coil and conform to ASTM standards and requested specifications.

The specification and length per coil can be customized according to customer’s requirements.

Duplex 2205 welded pressure tubing

2205 is a duplex (austenitic-ferritic) stainless steel containing about 40 - 50% ferrite in the annealed condition. 2205 has been a practical solution to chloride stress corrosion cracking problems experienced with 304/304L or 316/316L stainless.

Features:

High resistance to chloride stress corrosion cracking

Chloride pitting and crevice corrosion resistance superior to 317L stainless

Good general corrosion resistance

High strength

Good sulfide stress corrosion resistance

Useful up to 600°F

Applications:

Chemical process vessels, piping, and heat exchangers

Oil field piping, heat exchangers

Instructions for 1/8” Hydraulic control line

1/8” Hydraulic control line, also called capillary tube, mainly used for oil and gas field underground capillary pressure measurement. The temperature and pressure sensor (also known as a downhole permanent pressure gauge, generally a nitrogen cylinder) and the production string of the oil and gas well are run into the oil and gas layer several kilometers deep, and then the 1/8 “hydraulic control line (capillary) The temperature and pressure sensors are always connected to the surface of the fluorescent display, so that the downhole temperature and pressure can be transmitted to the surface through the capillary tube, and the instantaneous temperature and pressure at the downhole oil and gas layer can be read out through the fluorescent screen of the surface display, thereby realizing the downhole temperature and pressure,so as to realize the real-time monitoring of downhole temperature and pressure. It can also be used for pressure control of surface ety 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.

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.
