People have been using pipes for thousands of years. Among the first people to use pipes were ancient agriculturalist that diverted water from streams and rivers into farmer’s fields. In tropical countries reeds were used as pipes to transport water. As the world developed, more and better materials were found to be suitable for piping. Some of these materials include plastic, steel, copper and aluminium.
A visit to any processing plant will reveal the importance of piping. Pipes are used to carry various fluids from one point to another. A range of liquids and gases are transferred in pipes; for example: drinking water, chemicals, gases, acids and steam.
Pipes come in different lengths, shapes and sizes. At times it might be necessary to join pipes together or to join pipes to other equipment. How are pipes joined to other pipes and equipment? This is made possible by using “fittings”. What joining methods are used? Pipes can be joined by using screwed fittings, by welding or by using a variety of attachments.
