Slip On Flanges
Slip On Flanges
Slip On Flanges is a tool that is extensively used in joining pipes. A well-known, effective and reliable joining method for tubes and pipes, it is used in multiple commercial and business sectors where long tubes/pipes have to be connected. Whether it is construction, drilling, sewerage, or any other field, flanges are used in pipes when joints need to be dismantled, inspected or adjusted. It is used so that the pipes can be disassembled in future for maintenance and to fix blockages or leaks if they take place in the pipe. A Slip On Flanges is a very important part of pipes and tubes and has been in use for years. However, with time, it has undergone several changes. Today, Slip On Flanges are available in different designs with improved functionality.
One can find threaded flanges, socket-weld flanges, lap joint flanges, Slip On Flanges, blind flanges, weld neck flanges, and more in the market. These Slip On Flanges have their own specialty and make joining pipes a cakewalk with their smooth and hassle-free technique. For example, lap joint flanges are used where space is scarce and dismantling is required more often while Slip On Flanges are utilized in process piping where piping is done under high pressure and high-temperature conditions.

Slip On Flanges Applications
Slip On Flanges procured from Rexal Tubes are applied in tubes and pipes in numerous industries. They are an integral part of the pipeline system in diverse fields such as petroleum, water, oil & gas, pharmaceuticals, desalination, dairy & food processing, refinery & petrochemicals,breweries, and others. The Slip On Flanges are applied to connect pipes, pumps, valves, and other equipment to create a piping system. The advantage with Slip On Flanges is that they offer a lot of flexibility. They are detachable and hence, can be removed and fixed again after inspection or adjustment.
Flexibility is the prime feature of Slip On Flanges and it works in different fields because piping systems have different requirements and need flexible setting. Also, some pipe systems are quite long and cannot be installed and maintained without the help of Slip On Flanges. So, Slip On Flanges have become a part and parcel of the pipes/tubes system and since they are available in different dimensions and specifications, it is completely possible to meet the unique industrial requirements.
