When you need A335 P22 Pipe solutions that withstand extreme heat and pressure, our seamless chrome-moly alloy pipes deliver unmatched reliability. Designed for refinery systems, power plants, and petrochemical applications, these pipes combine superior creep resistance (up to 580°C/1076°F) with ASME-certified manufacturing. With 30% pre-stocked inventory and global certifications, we ensure your high-temperature projects stay on schedule.
The product is a chromium-molybdenum alloy steel seamless pipe engineered for high-pressure steam, hydrocarbons, and corrosive fluids. Manufactured under strict GMP guidelines, our pipes meet ASTM/ASME standards for chemical composition, tensile strength (≥415 MPa), and dimensional precision. Available in diameters from 1/4" to 24", they’re ideal for boilers, heat exchangers, and process piping requiring long-term thermal stability.
| Parameter | Details |
|---|---|
| Outer Diameter | 0.5" to 24" (Customizable) |
| Wall Thickness | SCH 10 to SCH 160 |
| Length | 6m to 12m (Cut-to-Size Available) |

✅ High-Temperature Durability
Chromium (2.0-2.5%) and molybdenum (0.9-1.1%) enhance oxidation resistance, making these pipes ideal for sustained 580°C environments.
✅ Seamless Construction
Advanced extrusion technology eliminates weld seams, ensuring uniform strength and leak-proof performance under high pressure.
✅ Global Compliance
Certified to ASME B36.10, EN 10216-1, and ISO 9001, with optional NACE MR0175 compliance for sour gas service.
✅ Urgent-Order Ready
15,000-metric-ton stock supports 7-day delivery to Europe, Asia, and the Americas.
✅ Customization
Tailor wall thickness, length, or end preparations (bevelled/threaded) within 15 days.
Every A335 P22 Pipe undergoes ultrasonic testing (UT), hydrostatic pressure checks, and hardness validation. Mill Test Certificates (EN 10204 3.1) are provided with every shipment.
Pipes are wrapped in anti-corrosion VCI film and secured in wooden crates to prevent transit damage—even in humid or saline environments.
Our GMP-certified facility combines advanced metallurgy knowledge with responsive 24/7 technical support for material selection and installation guidance.
