Looking on to the pressure vessel concept and parameters
Pressure vessel is a storage tank or vessel that has been designed to operate above 15 psgi. Common materials held and maintained by pressure vessel are propane, air, water, refrigerant, ammonia, and nitrogen. Many chemicals change their state on storage therefore Pressure vessels are often used to store chemicals due to their pressurizing capability. Important parameters when specifying pressure vessels are:
- Capacity
- Temperature range
- Maximum pressure.
Capacity is the volume of the pressure vessel. The temperature range indicates the temperature of the material the pressure vessel can withstand. Maximum pressure is the pressure range the vessel can withstand. In addition to pressurizing capability many pressure vessels have built-in temperature control. This helps to keep the volatile chemicals in their inert state.
There are two types of pressure vessel:
- Spherical pressure vessel
- Cylindrical pressure vessel.
Spherical pressure vessels are thin walled vessels. This forms the most typical application of plane stress. Cylindrical pressure vessel is a vessel with fixed radius and thickness subjected to internal gage pressure. This cylindrical vessel has an axial symmetry. Pressure vessel has a temperature that exceeds 750˚F and therefore the safety measure is of very much important. Vessels are created using three methods forging, welding and brazing. All the methods involve heating of metal pieces and joining them together. Forging refers to the formation of metal parts through the application heat and pressure. Welding refers to the process of joining two similar metal pieces. Finally brazing refers to the process of filling the space between the metals with non-ferrous metal.
Cracks and damage in vessels may cause severe rupture failure and leakage. Rupture failure may cause severe damage to life and property. Leaking of vessel causes severe health problems like suffocation, fire and explosion hazardous. These problems can be rectified by proper use and regular inspection.
Application of pressure vessel:
- Cosmetic industry
- Chemical industry
- Food and beverage industry
- Oil and fuel industry
- Paper and pulp industry
- Pharmaceutical and plastic processing
- Power generation
- Energy processing
The safe design, installation, operation and maintenance are required with appropriate codes and standards for the safety operation of pressure vessel. High pressure vessel functions under great pressure without compromising seals are bursting. Some pressure vessel monitor the temperature of their content with the series of gauge on the outside of the tank. Other types of pressure vessels are designed to store volatile substance at high temperature. Pressure vessel manufacturers design new tanks using variety of criteria, including the selection of materials to withstand shock, vibration, corrosion, temperature changes, and other environmental conditions.

When a container is pressurized then pressure is exerted against the walls of the vessels. Pressure is always normal to the surface regardless of the shape.
Pressure vessels store substances under pressure higher than atmospheric conditions, and are found all over the world. They are used at home for hot water storage, in many different factories and plants, and in mining and oil refineries.
Pressurized equipment is used in many industrial processes, for example in petrochemical plants, offshore oil rigs, gas storage and control systems.

For every product to look good it's important that the metals are joined properly and seamlessly. Needless to say, welding is one of the most important and key processes in any manufacturing process.
For a welder, the end product that is made to perfection justifies the hours of back breaking work that he had to endure to make sure everything is right and near perfect.
Let's not kid ourselves; a welder's job ain't fun! A welder's got to work in the hottest and sometimes in the most cramped up space as he brings to life the most complicated of designs.
Welding is an essential process which involves metals softened by applying heat, is used to affix two pieces together for various industrial purposes.
Welding is necessary in various fields to repair and weld automobile and other industrial components. The process of welding involves methods like fabrication, cutting, shaping and combining materials to make several products.
