High-Frequency Welded ASME SA213 TP321 Stainless Steel Seamless Tube | Extreme Heat-Resistant Boiler & Superheater Piping

Product Overview

Yuhong introduces ASME SA213 TP321 Stainless Steel Seamless Tubes, designed for extreme-temperature boiler and superheater systems. These tubes combine titanium-stabilized chromium-nickel alloy durability with superior oxidation resistance, ideal for demanding thermal environments.

Key Features

1. Material & Chemical Composition

Base Material: ASME SA213 TP321 Austenitic Stainless Steel (Ti-stabilized).
Chemical Composition:

Element	Cr	Ni	Ti	C	Mn
Composition	17.0-19.0%	9.0-12.0%	≥5×C%	≤0.08%	≤2.00%

Compliant with ASME SA213 and ASTM A213 standards.

2. Mechanical Properties

Property	Value
Tensile Strength	≥515 MPa
Yield Strength	≥205 MPa
Elongation (A50)	≥40%
Operating Temperature	Up to 900°C (1650°F)

3. Manufacturing Process

High-Frequency Welding (HFW): Ensures 95% weld integrity with seamless precision.
Heat Treatment: Solution annealing at 1010-1120°C followed by rapid water quenching.
Surface Finish: Pickling + passivation for enhanced corrosion resistance.

4. Applications

Boilers & Superheaters: Water walls, steam pipelines, and reheater coils.
Heat Exchangers: Petrochemical and power plant condensers.
Oil & Gas: High-temperature reformers and sulfur recovery units.

Advantages

High-Temperature Stability: Resists sensitization and intergranular corrosion at 450-850°C.
Corrosion Resistance: Performs in acidic, sulfur-rich, and chloride environments.
Customization: Available in OD 6-219mm and WT 0.5-30mm with lengths up to 18m.

FAQ

Q1: What certifications do you provide?
A: ASME, ISO 9001, EN 10216-5, and PED 2014/68/EU.

Q2: Can these tubes withstand thermal cycling?
A: Yes, titanium stabilization prevents carbide precipitation during repeated heating/cooling.

Q3: What is the lead time for bulk orders?
A: Standard lead time is 4-6 weeks for 20-ft container loads.
