Large-scale pressure vessel fabrication

SS Vessel

Our SS Vessel is a customized stainless steel process vessel designed for demanding applications involving mixing, reaction, storage, heating, cooling and pressure processing. As a professional manufacturer of Stainless Steel 304 Agitator vessels and Stainless Steel 316L Agitator vessels, we provide reliable solutions for chemical, pharmaceutical, food, biotechnology and specialty chemical industries. Each Stainless Mixing Vessel can be engineered with customized agitators, heating or cooling jackets, insulation, sanitary connections, pressure-rated nozzles and internal components according to specific process requirements. From material selection and precision fabrication to welding, inspection and pressure testing, every vessel is manufactured around the customer's operating conditions, process medium and applicable design standards.

Technical Specifications

Final technical specifications are determined according to process medium, capacity, pressure, temperature, viscosity, mixing requirements and applicable design standards.

Manufacturing Process

1. Material Inspection

Stainless steel plates, tubes, forgings and other materials are inspected according to project specifications before fabrication.

2. CNC Machining

Critical components such as flanges, tube plates, nozzles and agitator components can be precision-machined according to approved drawings.

3. Shell Fabrication

Plates are cut, formed, rolled and welded to manufacture the main vessel shell.

4. Head Fabrication

Elliptical, dished or other customized heads can be manufactured according to the vessel design.

5. Agitator Assembly

The agitator shaft, blades, mechanical seal and drive system are assembled and aligned according to the required mixing configuration.

6. Nozzle & Internal Assembly

Process nozzles, baffles, coils, jackets and other internal components are installed according to the approved design.

7. Welding & Inspection

Welding procedures, welder qualifications, visual inspection and applicable NDT are performed according to project requirements.

8. Pressure Testing

Hydrostatic or other specified testing is performed to verify the integrity of the completed vessel.

9. Final Inspection

Dimensional inspection, surface inspection, functional checks and documentation review are completed before shipment.

Material Selection Guide

Stainless Steel 304

Suitable for many general industrial mixing, storage and process applications where moderate corrosion resistance is sufficient.

Stainless Steel 316L

A preferred option for many pharmaceutical, food, chemical and high-purity applications requiring enhanced corrosion resistance.

Titanium

Suitable for selected highly corrosive or high-temperature applications where superior corrosion resistance is required.

Hastelloy

Suitable for severe chemical environments, particularly where strong acids, chlorides or other aggressive media may challenge conventional stainless steel.

Final material selection should always be verified against the actual chemical composition, concentration, temperature, pressure and service conditions.

Quality Control

Every SS Vessel can be subjected to project-specific quality control procedures, including:

• Raw Material Inspection
• Material Certificate Review
• PMI Testing
• Dimensional Inspection
• Welding Procedure Qualification
• Welder Qualification
• Visual Inspection
• Liquid Penetrant Testing
• Magnetic Particle Testing
• Radiographic Testing
• Ultrasonic Testing
• Hydrostatic Testing
• Surface Roughness Inspection
• Agitator Alignment Inspection
• Mechanical Seal Inspection
• Final Inspection

Project documentation can include material certificates, welding records, NDT reports, pressure test reports, inspection records and other required quality documents.

Why Choose Our SS Vessel?

Process-Based Engineering

We design the vessel according to the actual process rather than using a generic tank configuration.

Multiple Material Options

304, 316L, duplex stainless steel, titanium and Hastelloy options provide flexibility for different process environments.

Integrated Mixing Solution

The vessel, agitator, mechanical seal, heating/cooling system and instrumentation can be engineered as an integrated process package.

Customized Pressure Equipment

For pressurized applications, the vessel can be designed and fabricated according to applicable pressure equipment standards and project specifications.

Complete Manufacturing Control

Fabrication, welding, machining, assembly, inspection and pressure testing can be coordinated within one manufacturing process.

FAQ

What is an SS Vessel?

An SS Vessel is a stainless steel process vessel used for mixing, reaction, storage, heating, cooling or other industrial processing operations.

What is the difference between SS304 and SS316L?

SS316L generally provides better corrosion resistance than SS304, particularly in many chloride-containing and chemical environments. The correct material should be selected according to the actual process medium.

Can the vessel include an agitator?

Yes. Anchor, paddle, turbine, propeller, helical and customized agitators can be configured according to viscosity, mixing requirements and process conditions.

Can an SS Vessel operate under pressure?

Yes. The vessel can be engineered as a pressure-rated process vessel when the design pressure, temperature, materials and applicable code requirements are specified.

Can you manufacture titanium or Hastelloy vessels?

Yes. Titanium and Hastelloy can be considered for specialized applications requiring high corrosion resistance or resistance to aggressive process media.

Can the vessel be customized?

Yes. Capacity, diameter, height, material, agitator, jacket, insulation, nozzles, internal components, instrumentation and control system can all be customized.
