In times of budget cuts and lack of skilled workers, it is all the more important to use the right product solutions in your plant. In my current article I would like to explain the advantages of a close-coupled installation in the area of one of our products, “monoflanges”. That can have a very positive effect on your maintenance and operating work.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

In any process, all pressure measuring systems are connected using the standard installation.<\/p>

This standard installation is an interface of instrument (Transmitter\/Gauge) to the process. It includes intermediate isolation valves and some accessories.<\/p>

Many industries still use this method of installation for some of their processes.<\/p>

For example, in a refinery, a process line should have Double Block and Bleed operation. It should also have a Pressure Transmitter, as depicted in the below picture.<\/p>

The Pressure Transmitter is connected to an instrument manifold. An isolation valve follows it in series with another isolation valve to provide Block X Block operation. There’s another isolation valve between the other two that offers Bleed operation.<\/p>

But, this “conventional installation” is not perfect for the best process performance. It has many drawbacks, which are overcome by “close-coupled installation.”<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

In quite simple terms, close-coupled installation is an instrument mounting product. It brings the field instrument (Transmitter\/Gauge) closer to the process. That is, it enables a direct and minimal link between them.<\/p>

The design of a close-coupled installation must suit the application. It should also be suitable for the process.<\/p>

AS-Schneider has products that do Double Block and Bleed operation in a single valve. They serve as a close-coupled installation.<\/p>
