ASME SA335 P9 Chromium-Molybdenum Alloy Studded Finned Tubes for High-Temperature Furnace Applications

High-Frequency Welded ASME SA335 P9 Studded Finned Tubes | Durable Chromium-Molybdenum Alloy for Extreme Heat Furnace Systems

Product Overview

Yuhong Holding Group Co., Ltd. introduces ​ASME SA335 P9 Studded Finned Tubes, engineered for high-temperature industrial applications. Utilizing high-frequency welding (HFW) technology, these tubes combine chromium-molybdenum alloy durability with optimized heat transfer efficiency.

Key Features

1. Material & Chemical Composition
  • Base Material: ASME SA335 P9 Chromium-Molybdenum Alloy Steel.
  • Fin Material: High-grade stainless steel (AISI 304/316L) for corrosion resistance.
  • Chemical Composition:
Element Cr Mo C Mn Si
Composition 8.0-10.0% 0.90-1.10% ≤0.15% 0.30-0.60% 0.50-1.0%

Compliant with ASME and ASTM standards.

2. Mechanical Properties
Property Value
Tensile Strength ≥620 MPa
Yield Strength ≥415 MPa
Elongation (A50) ≥20%
Operating Temperature -20°C to 650°C
3. Manufacturing Process
  • High-Frequency Welding (HFW): Ensures 95% weld integrity between studs and base tube.
  • Studded Fin Design: Spiral studs (diameter: 8-12mm) increase surface area by 3-5x.
  • Post-Weld Treatment: Shot blasting and anti-corrosion coating (zinc or epoxy).
4. Applications
  • High-Temperature Furnaces: Cement kilns, steel reheating furnaces.
  • Heat Recovery Systems: Boilers, economizers.
  • Oil & Gas: Crackers, reformers.

Advantages

  1. Enhanced Heat Transfer: 30-50% higher efficiency compared to smooth tubes.
  2. Corrosion Resistance: Suitable for acidic or sulfur-rich environments.
  3. Customization: Available in lengths up to 18m and stud configurations (helical/axial).

FAQ

Q1: What is the lead time for bulk orders?
A: Standard lead time is 4-6 weeks for 20-ft container loads.

Q2: Can these tubes withstand thermal cycling?
A: Yes, the ASME SA335 P9 alloy ensures stability under repeated heating/cooling.

Q3: Are certifications available?
A: We provide ASME, ISO 9001, and EN 10204-3.1 certifications.
