ASTM A335 P5 Studded Tube - High Efficiency Heat Transfer for Boilers

STUDDED TUBE with A335 P5 Base Pipe: High-Temperature & Corrosion-Resistant Solution

1. Product Overview: Engineered for Extreme Conditions

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:

• Operating Temp: Up to 650°C (1,202°F)

• Pressure Rating: 20 MPa (2,900 PSI)

• Stud Configuration: Custom pitch/diameter

• Surface Treatment: Shot-blasted & anti-corrosion coating (optional)

2. Base Pipe Chemistry: Precision A335 P5 Alloy Composition

The A335 P5 base pipe delivers exceptional creep resistance and oxidation stability, critical for thermal applications. Certified to ASTM A335 standards:

3. Applications: Mastering Thermal & Abrasive Challenges

• Power Generation: Boiler tubes in coal-fired plants (sulfur corrosion resistance).

• Petrochemical: Reactor internals for cracking units (temp. >550°C).

• Waste-to-Energy: Heat exchanger tubes in incinerators (abrasion/acid resistance).

• Cement Industry: Preheater ducts for kilns (thermal cycling endurance).

4. Customization: Tailored for Your System

We engineer studded tubes to exact operational demands:

• Stud Patterns: Radial/helical layouts; materials (SS310, Inconel®).

• Dimensions: Base pipe OD 25–500mm; length ≤18m.

• Certifications: EN 10204 3.1, ASME Section IX welding compliance.
