A fitting is a joint or connector that is used in a piping system for gas or water connections. The fitting is termed as an elbow or union or tee. Unions and couplings are used to install significant movement in pipes along the axis of a pipeline. Unions do not require longitudinal movement as they are used to connect devices in gas lines.
Gas union fittings are a fluid connector transferring gas from a stationary inlet to a flexible pipe that connects a cylinder. Gas piping is also used for heating homes in cold places particularly in the northern latitudes. Transferring gas from an outside tank to a furnace is an efficient method to heat homes. The piping outside the house has branch lines that connect appliances. The connection at the joint will employ a union. At the connection point a sediment trap or a drip leg to collect water droplets is connected. This device has a nipple and a cap from where any foreign dirt or material is cleaned.
Unions made from casting are termed union ductile iron fittings. Introduced in the 17th century this technology is still in use with Georg Fischer fittings being one of the largest manufacturers in the world.
For domestic LP gas installations and natural gas piping unions are a critical component. It is important that the products follow the British Standard as this certification ensures that unions are manufactured to the highest standard. These standards are mandated to ensure safety. Buying unions is easy as there are several ecommerce portals online. The best resource for buying Unions is Gas Equipment Direct with perhaps the widest range in stock. They know the business of gas piping and installation due to their experience that exceeds over two and half decades. This experience has earned them a level of trust and reliability allowing customers to feel safe about the products.
