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:
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 |
We engineer studded tubes to exact operational demands:
a. Metallurgical Excellence
b. Quality Assurance
