When it comes to sourcing high-quality 2205 control line tubing, China stands out as a leading manufacturing hub offering extensive customization options. This article explores the possibilities, processes, and benefits of customizing Duplex 2205 control line tubing from a factory in China, providing a comprehensive guide for industries such as oil and gas, chemical injection, and hydraulic control systems.
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.
- 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.
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.
- Customization: Factories offer tailored solutions including size, wall thickness, length, and material specifications to meet specific project needs.
- Quality Assurance: Rigorous quality control processes including non-destructive testing, hydrostatic tests, dimensional accuracy checks, and mechanical property testing ensure product reliability.
- Competitive Pricing: Efficient manufacturing and supply chain management enable competitive pricing without compromising quality.
- Large Production Capacity: Many factories can supply large volumes, supporting projects with high demand.
- Technical Expertise: Experienced engineers and technicians provide technical support and customized manufacturing processes.
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.
- 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.
- 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.
- Polished bright finishes for corrosion resistance and sealing.
- Clean and bright surfaces suitable for hydraulic and chemical injection applications.
- 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.
The manufacturing of Duplex 2205 control line tubing in China involves several precise steps to ensure quality and performance:
High-grade Duplex 2205 stainless steel billets or strips are selected based on chemical composition and mechanical requirements.
- 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.
- 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.
- Tubes are polished to achieve bright, smooth surfaces.
- Optional extrusion of polymer coatings for environmental protection.
- Comprehensive tests including hydrostatic pressure, non-destructive examinations, dimensional checks, and mechanical property verification.
- Ensures tubing meets stringent industry standards for durability and safety.
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.
