In the context of pipes and joints, a coupling is a round hollow object that serves as a joining element for two pipes. Flexible pipe couplings are typically used in specific applications that are prone to such issues as angular deflection, uneven joining surfaces, vibration and so on. In short, flexible couplings can be said to be suitable in most applications where a rigid coupling might not prove to be efficient.
There could be several other reasons why flexibility in couplings is required. These includeVariations in temperature could cause a proportional change in the dimensions of the pipe. Certain pipes tend to expand in higher temperatures and contract in lower temperatures. A rigid coupling is not capable of responding and adjusting to these changes whereas a flexible coupling is made of materials that can adjust to the dimensional variations.As material flows through pipelines at various pressures it causes the pipelines to deflect slightly. These deflections, if not secured by a coupling that's flexible, could eventually lead to leaks and pipe bursts.Vibration is another inevitable component of a piping system. The materials that are used in the manufacture of flexible pipe couplings are capable of absorbing vibrations, thus preventing damage to the pipeline and the materials it conveys.
Now that you know all these factors, it becomes evident that rigid couplings, though widely used, are not always the most ideal product for all types of applications. Flexible coupling products are usually manufactured from light-weight, durable and flexible materials such as reinforced plastics, PVC, or even ductile iron and asbestos cement.
There are a myriad of environments where these couplings are used. These include: sewage treatment plants, conveying systems, food and beverage sector, chemical industries, manufacturing and processing industries, gas and fuel distribution, building construction and more.
These components can be easily procured from a leading manufacturer or distributor of pipe couplings and sewer fittings. When you are procuring these components, you should look for factors such as:Ease of installation and replacementDurability and long service lifeSecure fitting mechanismsLight in weightCost-effectiveness
There are various different types of flexible pipe couplings geared to different installation needs. You can find specific couplings for each of these requirements:Connecting two pipes that have different diametersConnecting pipes that may have a gap in betweenConnecting pipes that are not aligned perfectlyConnecting pipes that are configured with angular deflectionsConnecting pipes that might have cracks and need repair couplings
Adopting a lackadaisical approach when investing in couplings can cause severe damage to your pipelines and piping systems at a later stage. Hence, it is always a prudent decision to invest in high-quality flexible pipe couplings to begin with.
