In the building and construction industry, pipes and fitting materials play an important role in performing the task of conveying fluids. Materials used for manufacturing pipes depend on the type of fluid and the conditions under which they are conveyed. Fluids can be hazardous, reactive, volatile, corrosive or flammable. Fluids need to maintain their integrity when they are conveyed under process conditions such as different temperatures and pressures and hence, require pipe materials suitable。

A pipe system not only involves pipes but also other components such as pipe fittings, expansion and flexible joints, strainers, valves, bolts, flanges, gaskets and supports. Pipe fittings serve several purposes that mainly involves joining two pipes through appropriate fittings to alter the flow of the fluids or distribute them to other pipes. The materials used for pipe fittings also depend on the type of fluid and conditions under which they are being conveyed. Typically, they mirror the materials used in the pipes they help to join.

Some common materials used to make fittings include  nylon, aluminium, stainless steel, steel, copper, cast iron and brass. In order to standardize the storage, handling and stacking process for pipes and pipe fittings, the Central Public Works Department  Government of India, publishes and updates  Specifications’ regularly. These specifications are very comprehensive and include not only standards for building materials but also provide instructions for the execution and measurement of works and to determine rates.

These standards are followed by PWDs, PSUs, engineering departments, architects and build .These pipes should be stored on level grounds devoid of sharp objects and stones to ensure that they are supported throughout their lengths. They are also prone to distortion when kept under warm conditions causing difficulty in jointing and hence, storage in such conditions should be avoided. Further, large piles should be avoided. Spigot and socket pipes should be stored in layers with sockets placed on alternate ends to avoid imbalance in stacking.
