Carbon Steel Baffle Plate Support Plate ASME SA516 GR.70 For Heat Exchanger

Product Overview
Our Baffle and Support Plates are fabricated from ASME SA516 Grade 70 Carbon Steel, the industry-preferred material for internal components in shell-and-tube heat exchangers and pressure vessels. These plates play a critical, dual role: Baffle Plates direct shell-side fluid flow across the tube bundle for optimal heat transfer efficiency, while Support Plates prevent tube sagging and vibration-induced damage. Manufactured to precise TEMA standards, they ensure reliable performance and longevity in demanding industrial services.

Key Features & Advantages

Dual-Function Design: Baffle Plates (with segmental, double-segmental, or disc-and-doughnut cuts) create turbulent flow and increase heat transfer coefficients. Support Plates (with larger clearance holes) provide essential mid-span support for long tube bundles, safeguarding against failure.

Optimal Balance of Strength & Economy: SA516 Gr.70 provides excellent strength and toughness at a competitive cost, making it the standard choice for most water, steam, oil, gas, and non-aggressive chemical services.

Superior Fabricability & Consistency: This normalized steel plate offers consistent machining properties, allowing us to produce clean, precise cut edges and tube holes with tight tolerances for a perfect fit within the exchanger shell.

Proven Reliability: As a pressure vessel quality plate, SA516 Gr.70 is known for its dependable performance under thermal cycling and mechanical stress, contributing to the overall structural integrity of the heat exchanger.

Material Traceability: All plates can be supplied with complete Material Test Reports (MTRs) certifying compliance with ASME SA516 Gr.70 specifications for chemistry and mechanical properties.

Primary Functions in a Heat Exchanger:

Baffle Plate: Directs shell-side fluid, increases velocity, improves heat transfer, and reduces dead zones.

Support Plate: Provides mechanical support to tubes, minimizes deflection, and dampens flow-induced vibration (FIV).

Typical Applications

Power Generation: Feedwater heaters, condensers, lube oil coolers.

Oil & Gas Refining: Crude oil exchangers, product coolers.
