What Is 2205 Control Line Tubing?

2205 control line tubing refers to tubing made from Duplex 2205 stainless steel, a duplex stainless steel alloy known for its excellent strength and corrosion resistance. The alloy combines austenitic and ferritic stainless steel phases, offering superior mechanical properties and durability, especially in harsh environments like subsea oil and gas wells.

Key Features of Duplex 2205 Control Line Tubing

- Material Composition: Chromium (21-23%), Nickel (4.5-6.5%), Molybdenum (3.0-3.5%), Nitrogen enhanced for strength and corrosion resistance.

- Mechanical Properties: Yield strength ≥ 80,000 psi, tensile strength ≥ 95,000 psi.

- Corrosion Resistance: Excellent resistance to pitting, crevice corrosion, and stress corrosion cracking.

- Sizes: Outer diameters typically range from 1/8" to 1/2" (3.175 mm to 12.7 mm), with wall thicknesses from 0.02" to 0.083".

- Lengths: Up to 15,000 meters per coil, customizable per client requirements.

- Manufacturing Forms: Seamless, welded & redrawn, or welded with floating plug redrawn.

Why Choose a 2205 Control Line Tubing Factory in China?

China has become a global leader in stainless steel tubing manufacturing due to its advanced production technologies, cost advantages, and extensive experience in producing Duplex 2205 control line tubing for critical applications.

Advantages of Chinese Factories

Customization Options Available From Chinese 2205 Control Line Tubing Factories

1. Material Specifications

Factories can produce tubing from standard Duplex 2205 (UNS S32205/S31803) and related super duplex grades such as S32750, meeting ASTM A789 and ASME SA789 standards. Custom chemical compositions and mechanical properties can be specified.

2. Dimensions and Sizes

- Outer diameters from 1/8" (3.175 mm) up to 5/8" (15.875 mm) or larger.

- Wall thicknesses from 0.02" (0.5 mm) to 0.083" (2.1 mm).

- Lengths up to 15,000 meters per coil or cut-to-length options.

3. Manufacturing Types

- Seamless Tubing: Made by extruding and drawing billets, offering superior integrity without weld seams.

- Welded & Redrawn Tubing: Roll-formed and longitudinally welded strips, then redrawn to refine weld seams and improve mechanical properties.

- Encapsulation: Optional polymer coatings such as ETFE, FEP, HDPE, PFA, PVDF, or Nylon 11 for enhanced protection against abrasion and chemical exposure.

4. Surface Finishing

- Polished bright finishes for corrosion resistance and sealing.

- Clean and bright surfaces suitable for hydraulic and chemical injection applications.

5. Testing and Certification

- Non-destructive testing (ultrasonic, eddy current).

- Hydrostatic pressure testing up to 17,500 psi or higher.

- Dimensional and mechanical property inspections.

- Compliance with international standards such as ASTM, ASME, NACE MR0175/ISO15156.

Manufacturing Process of Customized 2205 Control Line Tubing

The manufacturing of Duplex 2205 control line tubing in China involves several precise steps to ensure quality and performance:

Step 1: Raw Material Selection

High-grade Duplex 2205 stainless steel billets or strips are selected based on chemical composition and mechanical requirements.

Step 2: Tube Forming

- For seamless tubing: Billets are heated, pierced, and drawn to form hollow tubes without weld seams.

- For welded tubing: Stainless steel strips are roll-formed and welded longitudinally using TIG or laser welding.

Step 3: Redrawing and Annealing

- Welded tubes undergo redrawing with a floating plug to smooth weld seams and improve dimensional accuracy.

- Tubes are cold drawn to final sizes, increasing strength and surface finish.

- Annealing heat treatment relieves internal stresses and enhances corrosion resistance.

Step 4: Surface Finishing and Encapsulation

- Tubes are polished to achieve bright, smooth surfaces.

- Optional extrusion of polymer coatings for environmental protection.

Step 5: Quality Control and Testing

- Comprehensive tests including hydrostatic pressure, non-destructive examinations, dimensional checks, and mechanical property verification.

- Ensures tubing meets stringent industry standards for durability and safety.

Applications of Customized 2205 Control Line Tubing

Duplex 2205 control line tubing is widely used in industries requiring high strength and corrosion resistance, including:

- Oil and Gas: Downhole hydraulic control lines, chemical injection lines, subsea umbilicals.

- Chemical Processing: Corrosion-resistant tubing for chemical injection and instrumentation.

- Marine Industry: Tubing resistant to seawater corrosion for offshore platforms.

- Power Generation: Control lines in power plants requiring high-pressure performance.

- Medical and Instrumentation: Precision tubing for medical devices and measurement instruments.

- Renewable Energy: Tubing for geothermal and other renewable energy systems.

Conclusion

Customizing 2205 control line tubing from a factory in China is not only feasible but also advantageous due to the country's advanced manufacturing capabilities, competitive pricing, and comprehensive customization options. Whether you need seamless or welded tubing, specific sizes, lengths, or protective encapsulation, Chinese manufacturers can tailor products to your exact specifications while ensuring stringent quality standards. This makes China an ideal sourcing destination for industries requiring durable, high-performance Duplex 2205 control line tubing for demanding applications.
