Product Description

1 / 8 ASTM A789 Downhole Chemical Injection Tubing Duplex 2205 Bright Annealed


TIPTOP manufactures precision control line tubing for hydraulic and chemical injection of onshore and subsea oil and gas wells. The control line tubing is manufactured in a number of different product forms including seam welded and redrawn, seam welded and floating plug redrawn and seamless depending on the customer’s specification and application.


Our production process is exquisite, the technology is mature, the product conforms to the international standard, already obtained the home and abroad customer's high recognition.Our control line tubing material has low content of sulfur and phosphorus, uniform structure, and suitable mechanical properties. All mechanical properties are in accordance with ASTM Standard. Using high quality raw materials and laser welding technology, our products have the characteristics of high strength, high plasticity, low cycle fatigue performance, high efficiency, low cost, safety and environmental protection.

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.


Duplex SS 2205 Corrosion-resistant control line tubing is one of our most competitive products, we have rich processing and supply experience. Our products are standardized and international, complying to ASTM A789 and all relevant industry standards, and have been exported to overseas markets in large quantities for many years.



Safety critical hydraulic control of sub surface safety valves

Subsea control lines

Downhole control and monitoring in intelligent well completions

Chemical injection using acids, surfactants and methanol

Coiled control line tubing is also used in onshore or topside hydraulic and instrumentation systems where the longer coils result in fewer connections and can increase the integrity of the overall system.


We have a mature quality control system to ensure a 100% qualified delivery rate:

Chemical composition analysis

Tensile testing




Hydrostatic testing

Eddy current testing
