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

Enhanced Heat Transfer: 30-50% higher efficiency compared to smooth tubes.
Corrosion Resistance: Suitable for acidic or sulfur-rich environments.
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.
