Product Overview

High-Frequency Welded ASME SA335 P9 Helical Finned Tubes are designed for extreme-temperature industrial furnace applications. These tubes combine chromium-molybdenum alloy durability with high-efficiency heat transfer, making them ideal for harsh environments.

Key Features

Material & Chemical Composition

Base Tube: ASME SA335 P9 Chromium-Molybdenum Alloy Steel (Cr: 8.5-9.5%, Mo: 0.90-1.10%)
Fin Material: High-grade stainless steel (AISI 304/316L) for corrosion resistance

Chemical Composition

Element	Cr	Mo	C	Mn	Si
Composition	8.5-9.5%	0.90-1.10%	≤0.15%	0.30-0.60%	0.50-1.0%

Compliant with ASME SA335 and ASTM A213 standards.

Mechanical Properties

Property	Value
Tensile Strength	≥620 MPa
Yield Strength	≥440 MPa
Elongation (A50)	≥20%
Operating Temperature	-20°C to 650°C

Manufacturing Process

High-Frequency Welding (HFW): Achieves 95% weld integrity between fins and base tube through automated spiral winding
Post-Weld Treatment: Shot blasting + anti-corrosion coating (zinc or epoxy) for enhanced durability
Quality Control: 100% hydrostatic testing (1.5x design pressure) and ultrasonic inspection

Applications

High-Temperature Furnaces: Cement kilns, steel reheating systems
Heat Recovery Units: Boilers, economizers, and air preheaters
Oil & Gas: Crackers, reformers, and sulfur recovery units

Advantages

Superior Heat Transfer: 4-7x higher efficiency than smooth tubes due to spiral fin design
Corrosion Resistance: Withstands acidic/sulfur-rich environments (pH 2-12)
Long Service Life: 2-3x lifespan over conventional welded tubes

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.
