Which type of welding is used in pressure vessel
 |
| Tank and pressure vessel welding |
Tank and pressure vessel welding fabrication There has been an increase in both the growth of cities and towns Number and size of tanks required for storage of water, oil, natural gas, and propane. Growth in the number of automobiles, trucks, and aircraft
Increased need for storage facilities for petroleum
products. In addition, our space and missile programs
This has created the need for the storage of oxygen,
nitrogen, and hydrogen in large quantities. Fertilizer
The industry needs volume storage facilities for ammonia. The basic material for many industries that supply
Miscellaneous products such as tires, clothing, soap, and
food
Products are stored in pressure vessels. Tanks and
vessels of all kinds have become one of the major applications of welding.
Welding replaced riveting in manufacturing
of pressure vessels about 65 years ago,
It improved the service performance of a pressure vessel through the elimination of
• Elimination of caustic embrittlement in riveted boilers
drum
• Economy in weight through high joint efficiency
and the elimination of butt-straps and rivets
• Reduction in size to meet the same service
Requirements
• More flexibility of design, allowing uniform, or on
least gradual, stress distribution
• Elimination of all completed fabricating stress
vessel by heat treatment
