Pipe couplings are an indispensable part of most pipelines and piping systems. These components are used for joining two pipes or executing a bend in a pipeline system. The joints and seams are known to be the most vulnerable part of a pipeline. This is the part that could turn out to be structurally weak, thus leading to leaks to even pipe bursts. But by securing joints and seams with the use of a high-quality coupling, this risk can be mitigated.
The couplings-also referred to as couplers-could vary in size depending on the size of the pipe they need to be fixed on. In fact, could be some couplings that measure over 5 feet in diameter. However, the more common variety of couplings are the ones that measure a few inches and are used on pipe lines in industrial, commercial, or residential facilities.
These couplings are available in rigid as well as flexible varieties. The flexible pipe connectors are used in pipelines that are prone to slight dimensional variations or deflections at the joints owing to temperature changes. These couplings play a very important part in keeping pipelines securely in place.
Couplers for pipes are found in a myriad of industrial sectors. These include HVAC applications, pulp and paper processing plants, cement manufacturing units, chemical processing plants, refineries, sewage treatment plants, food and beverage facilities, etc. They are also widely used in the construction industry.
- Pipe couplings should demonstrate at least some of these following desirable attributes:The fitting of the coupler is among the most important factors to consider. A coupling that doesn’t securely hold together joints is a futile investment. It is important for the fitting to be water-tight, flexible to just the right degree, and strong at the same time.
- The other important traits are corrosion-resistant manufacturing materials. Pipelines could have caustic materials flowing through them, and this could cause the couplers to corrode. Oxidation and corrosion are phenomena that put the security of your pipeline at risk.
- The strength and durability of a coupler is another important aspect that one cannot afford to ignore. The couplings should ideally not crack under pressure. Much of this depends on the quality of materials used in the manufacture of such couplings.
- Things don’t end at installation. Maintenance and repair are just as important. Thus, it is important that your chosen flexible pipe connectors are easy to install and just as easy to repair. You might want to check with your chosen distributor about the repair and maintenance costs of these components beforehand.
Finally, it is very vital to purchase only those components that comply with industry codes such as ASTM, UPC and so on. This will give you the assurance of buying safe and durable pipe couplings that last for several years.
