Product Specification

Heat Exchanger Baffle Plate Stainless Steel Asme SA240 SS304 Anti-Corrosion

Product Overview
Our baffle plates are precision-manufactured from ASME SA240 Type 304 Stainless Steel, offering superior corrosion resistance for shell-and-tube heat exchangers operating in demanding or hygiene-critical environments. These internal components are engineered to perform two vital functions: strategically directing shell-side fluid flow to maximize heat transfer efficiency and providing essential support to the tube bundle to prevent damaging vibrations. The SS304 construction ensures long-term durability against corrosive media, fouling, and oxidation, making it an ideal choice for chemical, marine, food, and pharmaceutical applications.

Material Specification & Key Properties
This product conforms to ASME SA240/ASTM A240 Standard Specification for Chromium and Chromium-Nickel Stainless Steel Plate, Sheet, and Strip for Pressure Vessels and for General Applications. Key specifications for Type 304 (UNS S30400) include:

1. Chemical Composition Requirements (Heat Analysis, % by Weight)

2. Mechanical Property Requirements (Typical for Plate)

Key Features & Advantages

• Superior Corrosion Resistance: SS304 provides excellent resistance to a wide range of oxidizing acids, organic chemicals, and atmospheric corrosion, protecting against rust and degradation in humid or chemically aggressive environments.

• Hygienic & Easy-Clean Surface: The non-porous, smooth surface inhibits scale buildup and bacterial growth, and is easily cleaned, making it perfect for food, beverage, and pharmaceutical processing.

• Dual Role in Exchanger Performance: As baffles, they create a tortuous flow path for the shell-side fluid, increasing turbulence and heat transfer rates. As supports, they stabilize the tube bundle against flow-induced vibration (FIV), preventing premature failure.

• Excellent Fabricability & Strength: Despite its corrosion resistance, 304 stainless steel offers good machinability and formability, allowing for precise cutting of segmental patterns and clean tube holes. It maintains strength at elevated temperatures.

• Material Certification: Available with full Mill Test Reports (MTRs) verifying compliance with ASME SA240 for chemistry and mechanical properties.

Typical Applications

• Chemical & Petrochemical: Heat exchangers handling corrosive process streams, acids, or solvents.

• Food, Beverage & Pharmaceutical (FDA-compliant): Sanitary heat exchangers for pasteurization, sterilization, and process temperature control.

• Marine & Offshore: Coolers and condensers exposed to saltwater or marine atmospheres.

• Power Generation: Condensers and coolers in coastal plants or where water treatment chemicals are used.

Technical Specifications (Summary)

• Material Standard: ASME SA240 / ASTM A240, Type 304.

• Plate Thickness: Supplied as per drawing, typically from 3 mm to 25 mm (1/8" to 1").

• Design: Cut to specified baffle type (Segmental, Double Segmental, etc.) and tube layout per TEMA standards.

• Certification: Material Test Certificate (MTR) available.

Why Choose Our SS304 Baffle Plates?
We combine certified stainless steel plate with precision laser or waterjet cutting technology. This ensures that every baffle plate not only meets your exact dimensional and functional requirements but also provides the inherent corrosion resistance needed to maintain performance and reduce maintenance costs over the entire lifecycle of your heat exchanger.
