Product Description
The Aidear Heavy-Duty Stainless Steel Shell and Tube Heat Exchanger is a rugged, high-efficiency industrial heat transfer device designed for reliable performance in demanding applications. As depicted in the manufacturing photo, this unit features a large-diameter cylindrical stainless steel shell with precision-welded construction, a fixed tubesheet design (tubes permanently expanded and welded into perforated tube sheets at both ends for cost-effective, leak-proof integrity), dense tube bundle, reinforced triangular welded supports for structural stability, oversized flanged nozzles (including side inlet/outlet and end covers), saddle-type mounting legs, and high-quality TIG welding visible on reinforcements—ensuring durability under high pressure, temperature differentials, and corrosive environments.
This fixed tubesheet configuration provides excellent thermal efficiency through direct heat transfer between shell-side and tube-side fluids, with minimal risk of leakage and simplified maintenance for non-fouling services. Fully customizable, it meets specific process needs while complying with industry standards like ASME, TEMA, or equivalent.
Product Type: Shell and Tube Heat Exchanger (Fixed Tubesheet configuration; other types like U-tube or floating head available on request)
Shell Material: Stainless Steel (304/316 or higher grades) for superior corrosion resistance, strength, and longevity
Tube Material: High-grade Stainless Steel, Copper, Titanium, or alloy options tailored to fluid compatibility and thermal conductivity
Tube Sheet Material: Stainless Steel (matching shell grade), precision-drilled and welded for secure tube fixation
Baffle / Support Features: Welded triangular reinforcements and baffles (custom spacing/types) to enhance turbulence, support tubes, and improve heat transfer coefficients
Nozzles / Connections: Flanged (ANSI, DIN, or custom), welded nozzles for high-flow integration; sizes and ratings adjustable
Mounting / Frame: Saddle supports or custom legs for stable installation
Operating Medium: Water, steam, thermal oil, refrigerants, glycol solutions, hydrocarbons, chemicals, or aggressive fluids
Design Pressure: Standard or high-pressure capabilities (custom up to several MPa, depending on application)
Design Temperature: Wide range, with materials selected for high/low extremes
Additional Options: Multi-pass arrangements, surface treatments (e.g., passivation), insulation, pressure relief, baffles for fouling control, and certifications
The fixed tubesheet design offers economical construction with high thermal performance via extended tube surface area and optimized flow patterns (shell-side baffles induce cross-flow for better heat transfer). Stainless steel build resists corrosion, erosion, and scaling, making it suitable for harsh industrial conditions. Easy to inspect and clean (via removable covers in some configs), it reduces downtime while handling large capacities and pressure/temperature swings efficiently—lowering energy use compared to less robust alternatives.
