High Pressure Vessels

LEHPV high pressure vessels contain liquids or gases under internal or external pressure. They are cylindrical vessels, the most common form for storing high pressure gases and fluids, supplied vertical or horizontal. Pharmaceutical, cosmetic, chemical, food processing and dairy processing plants use them as reactors, storage tanks and mixing vessels.

Design

A pressure vessel consists of a shell, heads and supports, plus attachments for its particular use. The shell is the cylindrical wall, made of metal plate whose thickness is calculated for the pressure of the contents. The plate is chosen both for pressure and for the corrosion caused by the stored medium. Shell materials include:

• Stainless steel
• Duplex steel
• Titanium alloy
• Hastelloy
• Inconel
• Monel Alloy

Nonferrous metal cladding is available. Heads are flat, torispherical, elliptical or conical.

Design pressure, volume and design temperature are set for each project and confirmed on request.

Heat transfer

Half-pipe coil jacket: metal formed into concentric coils and welded to the outside of the vessel. It allows rapid heating or cooling and is stronger than a dimpled jacket.

Conventional jacket: a cover over all or part of the vessel with an annular space between the vessel wall and the jacket wall. This is the most common jacket type.

Typical applications

• Jacketed reactors and chemical reactors
• Storage tanks and vacuum tanks
• Mixing vessels
• Distillation towers
• Autoclaves
• Heat exchangers

Specify for your project

• Vessel duty and medium
• Volume, design pressure and design temperature
• Shell material or cladding
• Head type
• Jacket type: half-pipe coil or conventional

Model family code: LEHPV.

This description defines the product family. Guaranteed performance, included hardware, exclusions, interfaces and acceptance criteria are stated only in the project-specific technical proposal and approved datasheet.

Cylindrical Pressure Vessels

• Cylindrical pressure vessels are the most commonly used vessels for storage of high pressure gasses and fluids.
• The “shell” of a pressure vessel refers to its wall, which is typically cylindrical. The shell is composed of metal plates with a thickness carefully calculated to sufficiently contain the pressure of the vessel’s contents.
• Vertical or horizontal types.
• Design to ASME, PED or GB150 on request.

Nonferrous Metal Cladding

These metal plates are typically made to withstand pressure, as well as the specific types of corrosion commonly caused by the materials it is intended to contain. Materials used for pressure vessel shells include but not limited to: Stainless steel, Duplex steel, Titanium alloy, Hastelloy, Inconel, Monel Alloy, etc.

Pressure Vessel Heads

Flat / Torispherical heads / Elliptical heads / Conical heads.

Heat Transfer

• Half pipe coil jacket：Half-pipe coil jackets consist of metal shaped into concentric circles or coils and welded to the exterior of the container. They are useful for rapid heating or cooling of the contents of the container and are stronger than mechanical dimpled jackets.
• Conventional jacket：The conventional jacket is a cover over all or part of the vessel with an annular space between the outer vessel wall and the inner jacket wall, generally concentric. This is the most popular jacket.

Uses of Pressure Vessels

Pressure vessels are useful for a wide range of applications, including:

• Jacketed Reactors
• Storage Tanks
•  Chemical Reactors
• Mixing Vessels
• Distillation Towers
• Autoclaves
• Heat Exchangers
• Vacuum Tanks

Common locations where pressure vessels may be found include Pharmaceutical, Cosmetic, Chemical, food processing and dairy processing facilities.

Pressure vessels are composed of a shell, head, and supports, with additional attachments as needed for the vessel’s particular application. Each component of a pressure vessel will have a different design and composition based on its intended use.
