Y-type strainer installation direction and installation precautions

The Y-type strainer is an indispensable strainer device in the pipeline system for conveying the medium. The Y-type strainer is usually installed at the inlet of a pressure reducing valve, a pressure relief valve, a fixed water level valve or other equipment to remove impurities in the medium. , In order to protect the normal use of valves and equipment. The strainer is suitable for liquid and gas materials in the production of chemical, petrochemical, light industry, etc., to strainer their solid impurities.

The Y-type strainer has the characteristics of advanced structure, low resistance, convenient sewage discharge, etc. The applicable medium can be water, oil, and gas. Generally, the water network is 18-30 mesh, the ventilation network is 10-100 mesh, and the oil network is 100-480 mesh. The basket strainer is mainly composed of a connection pipe, a main pipe, a strainer basket, a flange, a flange cover, and fasteners. When the liquid enters the strainer basket through the main pipe, the solid impurity particles are blocked in the strainer basket, and the clean fluid passes through the strainer basket and is discharged from the strainer outlet. What are the requirements for Y-strainer installation?

  • type strainer installation direction

When the Y-type strainer used for steam, gas, or liquid, the installation direction is also slightly different:

1. Steam or gas pipeline: the strainer screen faces the horizontal direction;

2. Liquid pipeline: install the strainer screen downwards;

3. Vertical installation: according to the installation direction of the strainer.

Precautions for installation of Y-type strainer

  1. The installation of the Y-type strainer should be carried out in accordance with the flow direction shown in the product sample and installation instructions provided by the manufacturer, as well as the recommended installation method and installation requirements.

2. The upstream and downstream of the Y-type strainer can be equipped with differential pressure gauges or pressure gauges according to the needs of process production to determine the blockage, and the back-flushing cleaning pipeline should be configured according to the process needs.

3. The convenience of installation and removal of permanent and temporary Y-type strainers should be considered when piping pipes.

4. Y-type strainer on pipeline design requirements

5. The pipeline equipped with Y-type strainer can be divided into intermittent operation and continuous operation during work.

6. When operating intermittently, set a shut-off valve before and after the Y-type strainer to clean the Y-type strainer

7.During continuous operation, two sets of Y-type strainers in parallel shall be installed for the permanent Y-type strainer, and a shut-off valve shall be set before and after the Y-type strainer (except for the line gap strainer)

In addition to the above 7 points, when installing a large-diameter socket-welded Y-type strainer, pay attention to whether the Y-type strainer gasket of this type is non-metallic. If it is a non-metallic material, it is easy to be damaged due to overheating, so After the welding is completed, the Y-type strainer should be quickly cooled to reduce the welding time
