Y-Strainers
|
Y-strainers are used to filter or strain out particulates from steam, gas or liquid application. The strainer is used when liquid is pass through for purification, separation or filtering from solid by means of a perforated or wire mesh straining element. The filter is used to prevent solid bodies from mixing in a liquid flowline. Strainers can aid in blocking pipeline debris such as rust, jointing compound and weld metal in pipelines system.
It is a high cost effective straining solution for many different type of application such as chemical processing, power generation, petroleum and marine industry, whereby the amount of solid material is removed from the flow is relatively small and resulting in long intervals between screen cleanings. |

What are Y-Strainers
1. What is the function of Y-Strainer?
|
The Y-strainer is important to apply in pipeline to protect pumps, control valves, flow meters, regulators and other process equipment from harmful effects. It reduces downtime and maintenance frequency and overall help to improve system performance efficiency. All strainer size offers maximum protection against foreign particles in piping system. Y-strainers are made of stainless steel material, which is completely corrosion resistant. Self-aligned screen is easily accessible for servicing and cleaning purpose.

2. Can Y-strainers be mounted vertical?
The strainer can be installed in flexible way either in vertical or horizontal position with the screen filter element and cover cap conditioning downward. For vertical installation, the flow must be downward into the inlet so that the strainer screen filter can collect solid material in the strainer at the lowest point. Y-strainer is used in liquid application, where sand and gravel are two common types of debris that pose a big threat to the application.
Y-strainer connects to the system main pipe at a diagonal angle in a Y shape. The Y-shape strainers are commonly applied in pressurized lines, liquid or gas, steam and vacuum or suction system. Frequent cleaning is required as the strainer has a lower dirt holding capacity than the basket type strainer. Screen cleaning can be done by simply opening and then closing the valve without shutting off the flow or disassembling the strainer.

3. How do you clean a Y type strainer?
The strainer screen is cleaned manually by shutting down the line and removing the strainer cap. When the strainer is working under safe medium, flush cleaning the strainer can be done by slowly unscrewing the bottom cap. During repairs or maintenance, the fluid must be piped to a safe discharge point to protect the entire system operation.

The interval between inspection and maintenance depends on service conditions. The pressure dropping across the element should be periodically checked and recorded in order to serve screen cleaning. To measure pressure drop across the element, two pressure gauges are encouraged to be installed at both inlet and outlet of strainer to have better measurement of system pressure reading. Small amounts of contamination can be cleaned by flushing the bottom cap. However, if the flushing is not sufficient, remove the screen by lifting out the bottom cover.

4. What is mesh size in strainer?
Y-strainer wouldn’t be able to do its own job without mesh filter that is properly sized. To select the strainer that matches a job requirement, it is important to understand the basic of screen and mesh sizing. There are two reading terms, mesh screen and microns are being use to describe the size of opening in the strainer to determine which debris of size passes the strainer and to flow in the system.

Mesh size indicates number of openings there are in the mesh across one linear inch. Example, a 10 mesh screen means that 14 openings across one inch and the same applies to a 120 mesh which means the opening hole much smaller, where there are total 120 openings per inch. The lower the mesh number, the smaller the sizes of particles that are allowed to pass through the strainer.
Micron is a unit of length used to measure small piece of debris and a micrometre calculation is one thousandth of a millimetre or about one twenty-five thousandth of an inch. |

Before installation, extra care has to be taken when using Y-strainer, follow instruction below:
|
Proper installation instruction for Y-strainer as below:
Step 1: Position the strainer to align with pipeline following the flow direction as the arrow label stamped on the strainer’s body.
Step 2: Prepare the other end of male connector to use in tightening and linking with the strainer.
Step 1: Position the strainer to align with pipeline following the flow direction as the arrow label stamped on the strainer’s body.
Step 2: Prepare the other end of male connector to use in tightening and linking with the strainer.
|
Step 3: The pipeline where the strainer installed must be conducted and assembled in non-bending, stretching force free and non-vibrations system.
Step 4: Ensure the installation is fully in place and the cover cap is pointing downward before starting up the system. Step 5: Before starting up the strainer via filling liquid from the system, ensure the bottom cap is closed and without leakage. Start up the system gradually to eliminate sudden shock to the strainer and piping system. |
