TEMA CLASS R Combined Feed Effluent Exchanger for Hydroprocessing Unit 100% NDE

TEMA CLASS R Combined Feed Effluent Exchanger for Hydroprocessing Unit

Introduction

Our Combined Feed Effluent Exchangers (CFEE) are engineered for maximum heat recovery in high-pressure, high-temperature hydroprocessing environments (such as hydrotreating and hydrocracking). By efficiently transferring heat from the reactor effluent to the incoming combined feed, our heat exchangers significantly reduce refinery energy consumption and furnace fuel costs.

Technical advantage:

• Premium Material Selection for Hydrogen Service : Utilizes high-grade Cr-Mo steels and stabilized stainless steels (e.g., TP321) to prevent Hydrogen Attack (HTHA) and sulfidation corrosion.
• Advanced Sealing Technology : Equipped with high-integrity bolted flange connections and custom gaskets to ensure zero-leakage under extreme thermal cycling and high pressures.
• Precision Tube-to-Tubesheet Joints : Strength welded and precision expanded joints to eradicate crevice corrosion and guarantee long-term mechanical reliability.
• 100% Non-Destructive Testing : All critical weld seams undergo strict RT (Radiographic) and UT (Ultrasonic) testing, followed by PWHT (Post-Weld Heat Treatment) to relieve residual stresses.

 Applications

• Hydrotreating Units (HDT) / Hydrocracking Units (HDC)

• Continuous Catalytic Reforming (CCR) Units 

• Petrochemical & Oil Refineries

Yuhong Holding Group is top 5 manufacturer of heat exchanger, pressure vessel, air cooler; We have strong documents system, strict quality control which is based on 3 mills. We have our own mills from tube production, finning process, and equipent fabrication. That's why we are good at urgent project.
