Stainless Steel 2205 capillary tubing is a high-performance alloy tubing known for its exceptional strength, corrosion resistance, and versatility in demanding industrial applications. For companies and industries requiring large quantities of this specialized tubing, the question often arises: Is Stainless Steel 2205 Capillary Tubing available for bulk orders? The answer is a resounding yes. This article explores the availability, specifications, manufacturing processes, applications, and suppliers of Stainless Steel 2205 capillary tubing, with a particular focus on bulk procurement options. We will also provide visual aids and videos to enhance understanding and conclude with a comprehensive FAQ section.
Stainless Steel 2205, also known as Duplex 2205, is a nitrogen-enhanced duplex stainless steel alloy. It features a balanced microstructure of approximately equal parts austenite and ferrite phases, which gives it superior mechanical and corrosion resistance properties compared to traditional austenitic stainless steels like 316L.
- High Yield Strength: Approximately double that of 316L stainless steel, with values exceeding 80,000 psi.
- Superior Tensile Strength: Around 95,000 psi, ensuring robustness under high pressure.
- Corrosion Resistance: Excellent resistance to chloride stress corrosion cracking, pitting, crevice corrosion, and sulfide stress corrosion.
- Good Weldability and Workability: Despite its high strength, it can be welded and formed without compromising properties.
- Hardness: Typically rated up to 30 Rockwell C, balancing hardness with ductility.
- Chemical Composition: Contains high chromium (21-23%), molybdenum (3.0-3.5%), and nitrogen (0.14-0.20%) for enhanced corrosion resistance.
Stainless Steel 2205 capillary tubing is widely available in bulk quantities from numerous reputable Stainless Steel 2205 Capillary Tubing Suppliers globally, including major manufacturers in China and other industrial hubs. Bulk orders are commonly fulfilled for industries such as oil and gas, chemical processing, marine, renewable energy, and instrumentation.
- Sizes: Outer diameters range from as small as 0.30 mm up to 31.75 mm, with wall thicknesses from 0.06 mm to 1.65 mm.
- Lengths: Tubing lengths can be customized, with maximum lengths reaching up to 15,000 meters per piece.
- Specifications: Manufactured to meet ASTM A789 and ASME SA789 standards.
- Customization: Suppliers offer options for diameter, wall thickness, length, surface finish, and end-forming (flaring, coning) to meet specific project requirements.
Leading Stainless Steel 2205 Capillary Tubing Suppliers include companies like Wide Steel, EMHK, and Stanford Advanced Materials, which provide bulk supplies with rigorous quality assurance and competitive pricing. These suppliers ensure:
- High-quality, certified materials.
- Customized production runs.
- Technical support for application-specific needs.
- Compliance with international standards.
This video demonstrates the production process, mechanical properties, and applications of Duplex 2205 capillary tubing, highlighting the precision and quality control involved in bulk manufacturing.
The production of Duplex 2205 capillary tubing involves several critical steps to ensure the tubing meets stringent mechanical and corrosion resistance requirements:
1. Raw Material Selection and Melting: High-quality raw materials including iron, chromium, molybdenum, nickel, and nitrogen are melted in electric arc or vacuum induction furnaces to ensure purity.
2. Casting and Hot Rolling: The molten steel is cast into billets, then hot-rolled to refine grain structure and mechanical properties.
3. Tube Forming: Tubes are formed either by welding (high-frequency or electric resistance) or seamless methods (piercing and extrusion).
4. Cold Drawing: Tubes are drawn through dies to reduce diameter and wall thickness, improving surface finish and dimensional accuracy.
5. Annealing: Tubes are annealed in controlled atmospheres to relieve stresses and stabilize the duplex microstructure.
6. Finishing: Straightening, cutting to length, surface polishing, deburring, and end-forming are performed as per customer specifications.
7. Quality Control: Non-destructive testing, hydrostatic pressure tests, dimensional inspections, and mechanical property verifications ensure compliance with ASTM A789/ASME SA789 standards.
Due to its excellent strength and corrosion resistance, Stainless Steel 2205 capillary tubing is used in a wide range of industries and applications:
- Oil and Gas: Downhole chemical injection lines, hydraulic control lines, and pipeline instrumentation to prevent wax and scale deposits.
- Chemical and Petrochemical: Transport of corrosive liquids and gases.
- Marine Industry: Resistant to seawater corrosion for shipbuilding and offshore platforms.
- Renewable Energy: Instrumentation and control lines in harsh environments.
- Medical Devices: Precision tubing for medical equipment requiring corrosion resistance.
- Instrumentation: Chromatography, remote thermometer systems, and measurement devices.
- Food and Beverage: Hygienic and corrosion-resistant tubing for processing lines.
- Power Generation: Heat exchanger tubing and steam lines.
Compared to traditional stainless steels like 316L, Duplex 2205 offers:
| Feature | Duplex 2205 | Stainless Steel 316L |
|---|---|---|
| Yield Strength | ~80,000 psi (double 316L) | ~40,000 psi |
| Tensile Strength | ~95,000 psi | ~75,000 psi |
| Corrosion Resistance | Superior in chloride-rich environments | Good, but less resistant to chloride stress corrosion |
| Wall Thickness | Can be thinner due to higher strength | Thicker walls required |
| Cost Efficiency | More cost-effective long-term due to durability | Lower initial cost but higher maintenance |
| Temperature Resistance | Stable up to ~300°C | Suitable up to ~300°C |
This makes Duplex 2205 the preferred choice for high-stress, corrosive, and high-temperature applications.
