Nichiboku's industrial Insights
Introduction
Foreign particles circulating through an industrial pipeline can damage pumps, valves, instruments, heat exchangers, spray nozzles, and other downstream equipment.
The WASINO KIKI (Japanese Y-Type Strainer) provides mechanical line protection by capturing solid contaminants through an internal screen before they reach sensitive equipment. Its compact configuration makes it suitable for integration into process and utility piping systems where reliable filtration and straightforward maintenance are required.
Engineered for Effective Line Protection: Japanese Y-Type Strainers
The Y-type configuration is one of the most widely used strainer arrangements in industrial piping.
WASINO KIKI offers Y-type strainers across a broad selection of:
Body and wetted-part materials
Connection types and flange standards
Nominal pipe sizes
Pressure ratings
Screen specifications
Application-specific configurations
The cast-body design incorporates an enlarged screen chamber that supports effective use of the internal filtration area.
Depending on the selected model and technical specification, installation may be possible in horizontal piping or vertical piping with downward fluid flow.
Technical Configuration Overview
Parameter | Available Configuration |
Manufacturer | WASINO KIKI CO., LTD. |
Product Type | Industrial Y-Type Strainer |
Primary Function | Removal of solid contaminants from process fluids |
Body Construction | Cast-body configuration with enlarged screen chamber |
Installation | Horizontal or vertical piping with downward flow |
Connections | Selected according to piping standard and application |
Materials | Multiple material options according to fluid compatibility |
Pressure Rating | Model and application-dependent |
Screen | Selected according to particle size and filtration requirement |
Regulatory Configuration | Versions available for Japan’s High Pressure Gas Safety Act, subject to specification and manufacturer confirmation |
Compatibility with Japan’s High Pressure Gas Safety Act must be confirmed for the exact material, connection, pressure rating, manufacturing specification, inspection scope, and documentation required.
It should not be assumed that every standard Y-type strainer configuration automatically meets this regulatory requirement.
Screen Selection and Pressure-Loss Control
The screen is the principal filtration component inside the strainer. Its opening size must be selected according to the contaminants present in the fluid and the protection requirements of downstream equipment.
A screen that is too coarse may allow damaging particles to pass. However, an unnecessarily fine screen may increase differential pressure, accelerate clogging, and require more frequent maintenance.
Technical selection should balance:
Required particle retention
Available filtration area
Normal flow rate
Fluid viscosity
Allowable pressure loss
Expected contaminant load
Cleaning and maintenance frequency
The screen specification should therefore be confirmed as part of the complete piping requirement rather than selected only by nominal pipe size.
Industrial Applications
Depending on the selected materials and technical configuration, WASINO KIKI Y-type strainers may be evaluated for:
Chemical and petrochemical process lines
Oil and gas facilities
High-pressure gas installations
Power-generation and utility systems
Marine and shipboard piping
Industrial water and cooling systems
Steam and condensate services
General manufacturing and process plants
The actual suitability of the strainer must be confirmed against the fluid, pressure, temperature, corrosion conditions, filtration requirement, and applicable piping standard.
Information Required for Technical Selection
Selection Requirement | Information to Provide |
Process Fluid | Liquid or gas type, composition, and concentration |
Pipe Size | Nominal diameter and actual piping dimensions |
Connections | Flange or connection standard, class, and facing |
Pressure | Normal operating pressure and design pressure |
Temperature | Normal operating temperature and design temperature |
Flow Rate | Normal and maximum flow conditions |
Materials | Required body, cover, screen, gasket, and wetted-part materials |
Screen | Perforation, mesh, particle size, and filtration requirement |
Installation | Horizontal or vertical piping and flow direction |
Dimensions | Required face-to-face and installation clearances |
Compliance | Applicable regulatory, inspection, and documentation requirements |
Replacement Unit | Manufacturer, model, drawing, nameplate, and equipment photographs |
Quantity | Required number of units |
Replacement Requires Complete Verification
A visually similar Y-type strainer should not automatically be considered interchangeable with the installed equipment.
A technically supportable replacement must confirm:
Exact manufacturer and model
Nominal size and face-to-face dimensions
Connection standard and pressure class
Body and screen materials
Screen perforation or mesh
Operating pressure and temperature
Flow direction and installation position
Required inspections and documentation
Differences in screen area, pressure rating, materials, internal geometry, and connection dimensions can affect filtration performance and installation compatibility.
