Basics of Pressure Vessels: Types, Applications, Designing and Manufacturing of Pressure Vessels.
Pressure vessels are containers that are designed to hold fluids or gases at a pressure that is different from the ambient pressure. These vessels are used in various industries, including petrochemical, oil and gas, pharmaceuticals, food and beverage, and power generation. Pressure vessels are used to store and transport a wide range of substances, including liquids, gases, and even solids.
Teknoflow is a company that specializes in the design and manufacture of various types of pressure vessels. With ASME U Stamp, R Stamp, and NB Stamp, Teknoflow can design and manufacture coded vessels to meet the specific requirements of its clients.
There are several types of pressure vessels, each designed to handle a specific type of substance or pressure. Here are some of the most common types of pressure vessels:
- Air Receiver Tanks: Air Receiver Tanks are pressure vessels that are used to store compressed air. These vessels are commonly used in industrial applications, such as in factories or workshops, to power pneumatic tools and equipment.
- Storage Tanks: Storage tanks are pressure vessels that are used to store liquids or gases. These vessels are commonly used in the oil and gas industry to store crude oil, natural gas, and other petroleum products.
- Separators: Separators are pressure vessels that are used to separate oil, gas, and water. These vessels are commonly used in the oil and gas industry to separate the different components of a well stream.
- Distillation Columns: Distillation columns are pressure vessels that are used to separate components of a mixture based on their boiling points. These vessels are commonly used in the chemical and petrochemical industries.
- Reactors: Reactors are pressure vessels that are used in the chemical and petrochemical industries to carry out chemical reactions. These vessels are designed to handle high temperatures and pressures and may have internal components such as agitators, baffles, or coils.
- Heat Exchangers: Heat exchangers are pressure vessels that are used to transfer heat from one fluid to another. These vessels are commonly used in HVAC systems, refrigeration, and chemical processing.
- Cylindrical Pressure Vessels: These are the most common type of pressure vessels and consist of a cylindrical shell with two end caps. They are used to store liquids and gases under high pressure, and can be found in various industries.
- Spherical Pressure Vessels: Spherical pressure vessels have a spherical shape and are used to store gases or liquids under high pressure. They are more expensive to manufacture than cylindrical vessels but are preferred for high-pressure applications where space is a constraint.
- Ellipsoidal Pressure Vessels: Ellipsoidal pressure vessels have a curved shape that resembles a squashed sphere. They are used for storage and transportation of fluids under high pressure.
- Torispherical Pressure Vessels: Torispherical pressure vessels consist of a cylindrical shell with a toroidal or dish-shaped end cap. They are widely used in the chemical, petrochemical, and pharmaceutical industries, and are preferred for high-pressure applications due to their strength.
- Conical Pressure Vessels: Conical pressure vessels are cone-shaped and are used to store and transport fluids or gases under high pressure. They are commonly used in the chemical and food industries.
Vessel heads are the end caps of pressure vessels, and they come in different shapes and configurations. The most common types of vessel heads are:
- Flat Heads: Flat heads are the simplest type of vessel heads, and they consist of a flat plate welded to the end of a cylindrical or spherical shell.
- Ellipsoidal Heads: Ellipsoidal heads have a curved shape that resembles a squashed sphere. They are preferred for high-pressure applications because they offer better stress distribution.
- Torispherical Heads: Torispherical heads consist of a dish-shaped end cap that is attached to a cylindrical shell. They are widely used in the chemical and petrochemical industries because they offer better stress distribution.
- Hemispherical Heads: Hemispherical heads have a curved shape that resembles half of a sphere. They are used in applications where pressure needs to be evenly distributed.
Pressure vessels are an essential component of many industries, and Teknoflow has the expertise and experience to design and manufacture vessels that meet the specific needs of its clients. With ASME U Stamp, R Stamp, and NB Stamp, Teknoflow can deliver vessels that meet the highest industry standards for safety and reliability.

FAQS:
Q1. What is a pressure vessel?
Ans: A pressure vessel is a container designed to hold gases or liquids at pressures significantly different from the surrounding environment. They are crucial in industries like oil, gas, chemical and power generation for safely storing and processing fluids under pressure.
Q2. What are the types of pressure vessels?
Ans: Pressure vessels are generally classified as vertical, horizontal, or spherical. The choice depends on factors like available space, type of fluid, operating pressure and specific industrial application requirements.
Q3. What materials are used in pressure vessels?
Ans: Pressure vessels are commonly made from carbon steel, alloy steel, stainless steel, or composite materials. Material selection is based on factors such as strength, resistance to corrosion, temperature tolerance and cost-effectiveness.
Q4. What are the main applications of pressure vessels?
Ans: They are widely used in industries such as oil and gas, chemical processing, power generation, and food & beverage. Applications include storage tanks, reactors, boilers, heat exchangers and fermentation vessels.
