Product Description
STUDDED TUBE with A335 P5 Base Pipe: High-Temperature & Corrosion-Resistant Solution
1. Product Overview: Engineered for Extreme Conditions
YUHONG STUDDED TUBE features a base pipe made of ASTM A335 P5 alloy steel, designed for superior performance in high-temperature and corrosive environments. The tube is welded with high-strength studs (typically SS304/316) to maximize heat transfer efficiency in boilers, reactors, and heat recovery systems. Key specifications:
- Operating Temp: Up to 650°C (1,202°F)
- Pressure Rating: 20 MPa (2,900 PSI)
- Stud Configuration: Custom pitch/diameter
- Surface Treatment: Shot-blasted & anti-corrosion coating (optional)
2. Base Pipe Chemistry: Precision A335 P5 Alloy Composition
The A335 P5 base pipe delivers exceptional creep resistance and oxidation stability, critical for thermal applications. Certified to ASTM A335 standards:
| Element | Composition (%) | Role in Performance |
|---|---|---|
| Chromium (Cr) | 4.0–6.0 | Enhances oxidation resistance |
| Molybdenum (Mo) | 0.45–0.65 | Improves high-temperature strength |
| Carbon (C) | ≤0.15 | Balances weldability & hardness |
| Manganese (Mn) | 0.30–0.60 | Increases toughness |
| Silicon (Si) | 0.50 max | Deoxidizes for purity |
| Phosphorus (P) | ≤0.025 | Reduces brittleness |
| Sulfur (S) | ≤0.025 | Minimizes hot cracking |
3. Applications: Mastering Thermal & Abrasive Challenges
- Power Generation: Boiler tubes in coal-fired plants (sulfur corrosion resistance).
- Petrochemical: Reactor internals for cracking units (temp. >550°C).
- Waste-to-Energy: Heat exchanger tubes in incinerators (abrasion/acid resistance).
- Cement Industry: Preheater ducts for kilns (thermal cycling endurance).
4. Customization: Tailored for Your System
We engineer studded tubes to exact operational demands:
- Stud Patterns: Radial/helical layouts; materials (SS310, Inconel®).
- Dimensions: Base pipe OD 25–500mm; length ≤18m.
- Certifications: EN 10204 3.1, ASME Section IX welding compliance.
