Precision-Engineered Shell & Tube Heat Exchangers for Oil, Chemical, and Power Industries
Shenzhen Hylita Shell & Tube Heat Exchangers consist of a shell with traditional plain tubes or enhanced surface tubes for high thermal performance. The fluids can be liquids or gases, one of which flows inside the tubes while the other flows outside the tubes within the shell. It is the most widely used heat exchanger in oil refineries and large chemical plants and is suitable for higher pressure applications.

Engineering Standards & Fabrication Quality
We don't just build equipment; we deliver compliance and safety. Every unit starts with rigorous thermodynamic modeling using industry-leading software to ensure your specific process requirements are met.
Manufacturing Compliance:
Design Codes: Full adherence to TEMA standards and EN 13445 (Pressure Vessel Directive).
Regulatory Compliance: Aligned with the 2014/68/EU PED (Pressure Equipment Directive).
Material Integrity:
- Body/Heating Tubes: EN 10216 & EN 10217 compliant.
- Tube Sheets/Covers/Baffles: Manufactured to EN 10025 & EN 10028.
- Flanges: EN 1092 standard for precise fluid and pressure classes.
Final Inspection: All units undergo hydrostatic pressure testing and custom painting before delivery. CE certification files are available upon request.
Anatomy of Efficiency
Our exchangers are constructed from four critical assemblies, each optimizing fluid dynamics:
- Stationary Head (Front Channel): The entry point that regulates flow distribution into the tubes.
- Rear Head: Manages the exit or redirection of fluid in multi-pass configurations, crucial for thermal efficiency.
- The Tube Bundle: The thermal core containing tubes, tube sheets, and baffles. Our baffle designs are calculated to maximize heat transfer while minimizing pressure drop.
- The Shell: The pressure vessel that houses the bundle, facilitating shell-side fluid interaction.
Note: We manufacture all TEMA designations, including Channels A-D, Shells E-X, and Rear Heads L-W, offering both fixed and removable bundle options.

ADVANTAGES & DISADVANTAGES OF SHELL AND TUBE HEAT EXCHANGER
ADVANTAGES
They can be designed and manufactured to operate under very high pressures.
They have an extremely flexible and fixed design.
They can be designed and manufactured to withstand very high and very low temperatures.
They are resistant to thermal shocks.
No size limit.
They can be used in all applications.
Pressure loss is at a minimum and can be kept to a minimum for process purpose.
They can be disassembled and reassembled for maintenance, repair and cleaning.
Tube diameter, tube number, tube length, tube pitch and tube placement can be changed. Therefore, the designs of tube heat exchangers are quite flexible.
DISADVANTAGES
The heat transfer coefficient is lower, so the heat transfer areas are usually large,
Cleaning and maintenance is inconvenient as movement space is required to remove the inner tubes,
In case of need, the heat exchanger capacity cannot be increased.
Why Choose Shell & Tube Technology?
Operational Resilience
These units are the workhorses of the industry. They excel in high-pressure environments and withstand severe thermal shocks that would compromise other exchanger types. From cryogenics to superheated steam, their operating range is vast.
Flexible Scalability
There are virtually no limitations on size. Whether you need a compact oil cooler or a massive petrochemical unit, the design adapts. Tube pitch, count, length, and layout are fully customizable.
Maintenance Friendly
Designed for the real world, our units allow for disassembly, making cleaning and repairs straightforward.
Engineering Considerations (Pros & Cons)
While Shell & Tube exchangers are unmatched in durability and pressure handling, they do typically require a larger footprint than plate exchangers to allow for tube bundle removal. They are designed for reliability over compactness.
Industry-Specific Solutions
We tailor thermal solutions to your exact application.
STEAM SHELL & TUBE HEAT EXCHANGERS
Steam Heat Exchangers are used for heating gas, water, oil and similar fluids by utilizing steam energy. These are one of the most efficient heat exchangers by enabling constant steam temperature during condensate generation
SUPERHEATED and HOT WATER HEAT EXCHANGERS
Hot water heat exchangers are used for heating gas, water, oil and similar fluids by utilizing superheated and hot water energy. Hot water heat exchangers offer a simple and effective solution. Armature of hot water heat exchangers are less costly compared to other processes.
SWIMMING POOL HEAT EXCHANGERS
Shell and Tube type heat exchangers produced for use in swimming pool heating are generally produced from 316L or 316Ti material. There is a usage area from small pools to large olympic pools in the range of 15KW-1750KW.
EXHAUST GAS HEAT EXCHANGERS
Exhaust Gas Shell and Tube Heat exchangers are used to increase the efficiency of stationary engines in combined cycle power plants, cogeneration and trigeneration systems. The energy obtained from cooling the exhaust gas is generally used to heat water or hot oil.
OIL COOLER HEAT EXCHANGERS
Oil cooler Shell and Tube heat exchangers are used for cooling of heat transfer oils, lubricating oils and cooling oils. These high quality products are produced with the combination of the best materials and the latest production techniques.
DOUBLE PIPE HEAT EXCHANGERS
It is frequently used in the food and pharmaceutical industries thanks to its high heat transfer. They are specially designed corrugated double pipe heat exchangers. While the product passes through the inner tube, the heater or refrigerant flows between the inner and outer tubes. Corrugated inner tube increases heat transfer. Thanks to the double pipes, even in case of a puncture, the fluids do not mix with each other.
EVAPORATOR AND CONDENSER
Evaporators are heat exchangers used to enable another fluid from waste gases or similar fluids to pass from liquid state to gas state at high temperatures.
Condensers are heat exchangers produced for the purpose of condensing secondary refrigerant or gas fluids by utilizing the energy of the process air.
