TEMA Heat Exchanger With Stainless Steel Shell SS316L For Power Plant

TEMA Heat Exchanger With Stainless Steel Shell SS316L For Power Plant

Product Overview

Our TEMA Stainless Steel SS316L Heat Exchanger is precision-engineered to meet the demanding requirements of modern power generation facilities, including thermal power plants, nuclear facilities, cogeneration plants, and combined cycle units. Designed and fabricated in full compliance with TEMA (Tubular Exchanger Manufacturers Association) standards and ASME Boiler and Pressure Vessel Code requirements, this shell-and-tube heat exchanger delivers exceptional corrosion resistance, thermal efficiency, and long-term reliability in critical power plant services.

The use of SS316L (UNS S31603 / 1.4404) austenitic stainless steel provides superior resistance to chloride attack, pitting, and crevice corrosion compared to standard 304 stainless steel. Its low carbon content (maximum 0.03%) prevents sensitization during welding, ensuring optimal corrosion resistance in heat-affected zones—a critical advantage for power plant applications involving high-purity water, steam condensate, and cooling water systems.

Key Features & Advantages

Superior Corrosion Resistance with SS316L Construction
The molybdenum addition (2.0-3.0%) in SS316L provides enhanced resistance to chlorides and reducing acids, making it ideal for power plant cooling water circuits, whether fresh, brackish, or seawater. The low carbon content ensures that welded joints maintain full corrosion resistance without the risk of intergranular attack.

Full TEMA Compliance

Our heat exchangers are designed to TEMA Class C (Commercial) or Class R (Refinery) standards as required by your application. We adhere strictly to TEMA mechanical design specifications for tubesheet thickness, baffle spacing, tie rod requirements, and all other critical design parameters, ensuring industry-standard dimensions and predictable performance.

ASME Code Design & Certification

Each unit is designed per ASME Boiler and Pressure Vessel Code Section VIII, Division 1, and is available with ASME U-Stamp certification. This ensures compliance with power plant safety regulations, insurance requirements, and global project acceptance.

Optimized for Power Plant Duty Cycles
Our engineering team designs specifically for power plant conditions, including thermal cycling, high-temperature operation, and varying flow rates. The result is a heat exchanger that maintains its integrity and performance throughout decades of service.

Complete Material Traceability

All SS316L components are supplied with full Mill Test Reports (MTRs) verifying chemical composition and mechanical properties. Positive Material Identification (PMI) testing is available for critical applications requiring additional verification.

Custom Design for Specific Applications
Whether you need a high-pressure feedwater heater, a large surface condenser, or a compact lube oil cooler, we customize the design to your exact process conditions, including tube diameter and wall thickness, baffle configuration, nozzle locations, and support structures.
