ASME SA240 304 Stainless Steel Tubesheet with Precision CNC Drilled Holes for Heat Exchanger Core Compliant with TEMA Standards

Are you looking for a cost-effective, corrosion-resistant solution for a non-seawater thermal system? For light to medium-duty industrial applications, choosing a rolled plate tubesheet over an expensive forging is the smartest way to optimize your equipment budget.

Yuhong Group Co., Ltd. specializes in manufacturing precision‑drilled ASME SA240 304 (SA240 Type 304) stainless steel plate tubesheets. As a core structural anchor in shell and tube heat exchangers, our rolled plate tubesheets provide stable mechanical properties, excellent sanitization, and reliable tube-to-tubesheet sealing performance for mainstream processing industries worldwide.

For moderate thermal cycles, utilizing certified ASME SA240 Grade 304 rolled plate significantly slashes material lead times and upfront procurement costs compared to ASTM A182 forged blanks.

[ Structural Choice Based on Engineering Parameters ]
├── ASME SA240 304 Plate: Best for Thickness ≤75mm, Pressure ≤30 bar (Highly Cost-Effective)
└── ASTM A182 F304 Forging: Required for Heavy Wall Thickness, High Pressure & Extreme Thermal Cycling

• Economical Corrosion Resistance: Grade 304 austenitic stainless steel offers excellent resistance to organic acids, potable water, steam, and food-grade clean fluids (Pitting Resistance Equivalent Number, PREN≈19.

• CNC Precision Micro‑Drilling: Every tube hole is executed via automated multi-spindle CNC drilling to achieve micro-tolerances of +0.05 / -0.00 mm, preventing bypass leakage and ensuring a seamless fit for stainless steel seamless tubes.

• Annular Expansion Grooves: Machined with 2 or 3 precision grooves per hole to maximize the mechanical pull-out strength of cold-drawn tubes during the hydraulic expansion (rolling) phase.

Every plate tubesheet is supplied with a certified EN 10204 3.1 Mill Test Certificate (MTC) guaranteeing raw material chemical and mechanical compliance.

• Food & Beverage Processing: Pasteurization systems, juice/syrup coolers, and sanitary dairy equipment.

• Pharmaceutical & Biotech: Water for Injection (WFI) cooling loops and high-purity water distribution skids.

• HVAC & District Heating: Steam-to-water converters and commercial building hot water generators.

• Power Station Auxiliaries: Demineralized water preheaters and turbine lube oil cooling systems.

When replacing a fouled or leaking heat exchanger tubesheet, avoiding structural discrepancies is vital. Please cross-reference these points before ordering:

1. Verify Tube Pitch & Pattern: Confirm if your layout uses a Triangular (30° / 60°) arrangement for high thermal transfer or a Square (90°) pattern to facilitate outer tube mechanical cleaning.

2. Gasket Surface Configuration: Specify the sealing profile—Flat Face (FF), Raised Face (RF), or Tongue & Groove—matching your spiral-wound or metal-jacketed gasket requirements.

3. Baffle Alignment Verification: Ensure that pass-partition lines and structural tie-rod bolt patterns perfectly match your channel or bonnet layout.

Yuhong Group is a global manufacturer of individual components as well as fully integrated heat exchanger tube bundles:

• Heat Exchanger Tubes: Matching stainless steel seamless tubes (304/304L/316L) cut‑to‑length with end preparation.

• Extended Surfaces: Aluminum-finned tubes (fin tubes) for industrial air coolers.

• Internal Hardware: Machined segmental baffles, tie rods, carbon steel spacers, and custom gaskets.
