What is a water joint?

Water joint is any device or procedure used to facilitate the connection of water pipes or include auxiliary devices while maintaining the integrity and continuity of the pipeline. The joints of the water pipe can be permanent or removable depending on the application and type of pipeline. These joints can be rigid or flexible or even include elements of the bellows type expansion to increase the water pressure. Water joints may include any external parts and rely on welding, soldering or soldering pipes or fittings themselves or consisting of separate fasteners. Water joints should be able to carry the same pressure as the rest of the pipeline without leakage or experience of mechanical failure. The average installation of the ALSO water pipe often changes direction or altitude and will have many branches, distribution or extension along its route. All these deviations and supplements require a waterproof joint between different sections of pipes, fittings and external equipment. Type of used joint of veilISI on a number of factors. These include pipe size, pipe material, system pressure and whether joint or assembly require regular removal or maintenance.

There are several different types of water joint, each of which has its own advantages and a specific area of ​​the application. Two main classifications of water pipe joints are permanent and removable. Permanent water joints include welded, soldered and soldered trade unions and are generally used on smaller copper water pipes and a very large steel distribution network. Welded water joint on large networks is usually part of the prefabrication system of the sequence and is usually carried out before installation outside the site. However, steel water pipes can be welded in place to affect repairs or system supplements.

Smaller systems of local copper pipes are often connected or fried with pipes and fittings together. If properly done, welded, solderThe water joint is often the strongest and most durable of all joints. Removable joints usually consist of flange, shells and two -piece compression fittings. The flange water joint consists of two similar discs that are located at the ends of the pipeline to connect. Between these two, the wrapping element is introduced and are connected together. This attracts two flanges firmly against each other, thus creating a waterproof joint.

The

compression and joints of the shell are usually two partial fittings with an internal compression seal. One half is located at each end of the pipeline and is screwed together to compress the seal element and create a waterproof joint. This type of joint will be replaced quickly if the seals wear or damaging and allow the perimeter of the pipeline or the inclusion of other fittings. Simple single -element joints are also often used on steel pipes and consist of a simple threaded sleeve comforted with a hemp string or PTFE tape. The mostThe most important defining characteristics of all water joints is their ability to carry the system pressure without leakage or allow contaminants and air to enter.
