It’s critical to grasp the precise functions and features that distinguish each strainer before picking which one to employ. “Y” strainers aren’t any different. While this strainer type is more versatile than basket strainers, the “Y” strainers have a limited installation. The purpose of a Y type strainer is precise, which is exactly what makes them excellent for the situations in which they can be employed.
Y-Strainers are devices that use a perforated or wire mesh straining element to mechanically remove undesired materials from liquid, gas, or steam lines. Pumps, metres, control valves, steam traps, regulators, and other process equipment are all protected by them in pipes.
In many applications, Y-Strainers are a very cost-effective straining option. The strainer screen is manually cleaned by shutting down the stream and removing the strainer cap when the amount of material to be removed from the flow is very small, resulting in extended intervals between screen cleanings. Y-Strainers can be equipped with a “blow-off” connection that allows the screen to be cleaned without having to remove it from the strainer body in applications where there is a lot of debris.
In numerous industries, such as chemical processing, petroleum, power generation, and maritime, Y-Strainers are employed in a range of liquid straining applications to safeguard downstream process system components. Y-Strainers are commonly used in water handling applications to protect equipment from being damaged or blocked by undesirable sand, gravel, or other debris.
While a Y-Strainer is commonly employed in a variety of liquid applications, it is the industry standard for steam applications and is nearly universally used. Its compact, cylindrical design is extremely durable and capable of withstanding high pressures. It’s a pressure vessel in the literal sense. It’s fairly uncommon to see Y-strainers that can handle pressures of up to 6000 psi. Of course, the strainer’s design is crucial in these situations to ensure that it can withstand the high pressures without failing. When dealing with high-pressure steam, temperature becomes a problematic aspect. Standard carbon steel is not always adequate for steam pressures of 1500 psi or greater, because the steam temperature can reach 1000° F or higher. In these cases, the Y-Strainer body is generally made of chrome-moly steel.
Unlike other types of strainers, a Y-Strainer has the advantage of being able to be installed in either a horizontal or vertical position. Obviously, in both cases, the screening element must be on the “down side” of the strainer body so that the entrapped material can properly collect in it.
