Bimetallic Stainless Steel Tube: TP304L/SA210-A1

Product Overview
Engineered with dual-layer metallurgy, this bimetallic tube combines TP304L austenitic stainless steel (outer layer) with SA210-A1 carbon steel (inner layer), delivering optimized corrosion resistance and structural strength. Ideal for high-pressure and corrosive environments in power plants, chemical processing, and oil refineries.

Key Features

• Corrosion Resistance: TP304L outer layer provides exceptional resistance to acids, chlorides, and oxidizing agents.

• Mechanical Strength: SA210-A1 inner layer ensures high tensile strength and pressure-bearing capacity (up to 45 MPa).

• Thermal Stability: Compatible with operating temperatures ranging from -40°C to 650°C.

Technical Specifications

• Standards Compliance: ASTM A312 (TP304L) / ASME SA210 (Grade A1).

• Dimensional Range: OD 21.3–508 mm, wall thickness 2.0–12.0 mm.

• Interlayer Bonding: Explosion-bonded interface guarantees metallurgical integrity.

Applications

• Boiler heat exchangers in coal-fired power plants.

• Chemical transport pipelines with mixed media.

• Structural components requiring cost-efficient corrosion protection.
