Stainless Steel Tubular Heat Exchanger for Pharmaceutical & Solvent Recovery

Product Overview

Yangzhou Tongyang Chemical Equipment Co., Ltd. (TONGYANG) manufactures customized stainless steel tubular heat exchangers and pressure-rated heat transfer equipment for pharmaceutical, food processing, fine chemical and solvent recovery applications.

Our tubular heat exchangers are designed to provide efficient heat transfer between process fluids and heating or cooling media. Depending on the process requirements, they can be configured for heating, cooling, condensation, evaporation and solvent recovery duties.

Manufactured according to approved technical specifications, TONGYANG heat exchangers are available in various shell and tube configurations, with material selection, surface finishing and inspection requirements tailored to each project.

Heat Exchanger Design and Construction

TONGYANG supports customized single-pass and multi-pass tubular heat exchanger configurations according to thermal and mechanical design requirements.

Available design options may include:

Fixed tubesheet, U-tube and floating head configurations

Horizontal and vertical installation

Stainless steel pressure vessel construction

Customized heat transfer areas and tube arrangements

Steam, hot water and thermal oil heating applications

Cooling water and other suitable cooling media

Condensation and reboiling equipment configurations

Sanitary process connections where required

Optional insulation and equipment supports

The final configuration depends on process conditions, pressure drop limitations, cleaning requirements and applicable design standards.

Materials and Surface Treatment

Material selection depends on the process medium, operating conditions, corrosion resistance requirements and product cleanliness specifications.

Common material options include:

Stainless steel 304 / 304L

Stainless steel 316 / 316L

Selected corrosion-resistant alloys, subject to technical evaluation

For applications requiring enhanced cleanliness, project-specific options may include:

Internal mechanical polishing

Electropolishing

Pickling and passivation

Specified surface roughness requirements

Material traceability and inspection documentation

Suitable gasket and sealing material selection

For pharmaceutical and food-contact applications, material compatibility, surface finish and hygienic design requirements should be defined in the customer's technical specifications.

Pressure Vessel Design and Manufacturing

Where the equipment falls within the scope of a pressure vessel design code, TONGYANG can manufacture according to applicable requirements of:

ASME Section VIII Division 1 or Division 2

GB/T 150 and applicable Chinese pressure vessel standards

Other agreed project specifications, subject to engineering review

TONGYANG holds ASME U/U2 manufacturing qualifications and China's A2 pressure vessel manufacturing license.

Pressure and temperature limits are determined by the approved mechanical design rather than a fixed standard product range.

Inspection and testing are performed according to the applicable design code and approved inspection and test plan.

Hygienic Design Options

For pharmaceutical and food processing applications, customized equipment may incorporate hygienic design features according to project requirements.

These may include:

Polished stainless steel product-contact surfaces

Hygienic fittings and sanitary connections

Drainable equipment arrangements

Clean-in-place (CIP) compatibility

Steam-in-place (SIP) compatibility, where specified

Appropriate gasket and sealing materials

Inspection and cleaning access

Material and surface finish documentation

CIP/SIP temperatures, cleaning chemicals and material compatibility must be evaluated for the selected equipment configuration.

Where pharmaceutical validation is required, documentation and qualification support can be discussed as part of the agreed project scope.

Applications in Solvent Recovery

Tubular heat exchangers can serve different functions in solvent recovery and chemical separation systems.

Solvent Condensation

Used to condense suitable solvent vapors from distillation columns, evaporation systems and recovery processes.

Process Fluid Heating

Provides controlled heating of liquid streams before distillation, evaporation or other separation operations.

Reboiling and Evaporation

Shell and tube heat exchangers can be configured as reboilers or evaporators within suitable solvent recovery systems.

Heat Recovery

Transfers available heat between compatible process streams to improve overall plant heat integration.

Pharmaceutical and Fine Chemical Processing

Customized stainless steel heat exchangers can be incorporated into processing systems where cleanliness, material compatibility and controlled operating conditions are required.

The achievable solvent recovery rate depends on the complete process design and cannot be guaranteed by the heat exchanger alone.

Manufacturing and Quality Assurance

TONGYANG provides customized pressure vessel and tubular heat exchanger manufacturing supported by established fabrication, welding, machining and inspection capabilities.

Our manufacturing and quality control activities may include:

Material identification and traceability

Welding procedure qualification

Tubesheet machining and tube bundle fabrication

Tube-to-tubesheet joining

Dimensional inspection

Non-destructive examination

Hydrostatic testing

Surface treatment and inspection

Factory Acceptance Testing (FAT)

Third-party inspection coordination

The inspection scope and documentation package are determined by the applicable design code and project specifications.
