Meta Description: Custom ASME SA240 Type 304 stainless steel plate tubesheets for light to medium duty heat exchangers. Fast 1-2 weeks lead time, precision CNC drilled & grooved to TEMA standards. Contact jimmy@steelseamlesspipe.com for a quote.
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.
