Marine Duplex Oil Strainer
Product Overview
Our marine duplex oil strainer, which strictly adheres to the JIS F7208 standard, is a high – performance cast – iron device specifically engineered for the filtration of fuel and lubricating oil in marine pipeline systems. Its innovative dual – chamber design is a key feature that ensures uninterrupted and continuous operation. This design allows for one chamber to be in use while the other can be cleaned or maintained, minimizing downtime and ensuring the smooth flow of oil in marine applications.
Standards & Comprehensive Testing
- Design Standard Compliance: The strainer is designed in strict accordance with JIS F7208 – 2005, a well – recognized and widely used standard in the marine industry. This ensures that the product meets the highest quality and performance requirements for marine oil filtration.
- Test Standard Adherence: It has undergone rigorous testing as per JIS F7200 – 1996. This comprehensive testing process guarantees that the strainer can withstand the harsh conditions and demands of marine environments.
- Pressure Ratings Details:
- Hydraulic Test: The body of the strainer has been tested to withstand a hydraulic pressure of 0.6 MPa, while the seal has been tested to handle 0.44 MPa. This ensures that the strainer can effectively contain the oil under pressure without any leakage.
- Max. Working Pressure: The maximum working pressure of the strainer is 0.4 MPa, providing a safe and reliable operating range for marine fuel and lubricating oil filtration.
Dimensions & Precise Connections
- Nominal Size Range: The strainer is available in a range of nominal sizes from DN25 to DN125, catering to different pipeline diameters in marine applications. This wide size range makes it a versatile solution for various marine vessels and systems.
- Flange Standard Specification: It features flanges that comply with the JIS B2220 standard, with pressure classes of 5K and 10K. This ensures easy and secure connection to marine pipelines, facilitating a leak – free and efficient installation process.
Material Specifications for Enhanced Durability
| Component | Grade | Material |
|---|---|---|
| Body | FC200 | Cast Iron: The body is made of high – quality FC200 cast iron, which provides excellent strength and durability. It can withstand the mechanical stresses and vibrations commonly encountered in marine environments, ensuring long – term reliable performance. |
| Bonnet | FC200 | Cast Iron: Similar to the body, the bonnet is also constructed from FC200 cast iron, contributing to the overall robustness of the strainer. This ensures that the internal components are well – protected and the strainer can operate effectively under various conditions. |
| Strainer Basket | SS400 / SUS304/SUS316 | Carbon Steel / Stainless Steel: The strainer basket is available in different materials, including SS400 carbon steel and SUS304/SUS316 stainless steel. The carbon steel option offers good strength and cost – effectiveness, while the stainless steel options provide superior corrosion resistance, making them ideal for marine applications where exposure to saltwater and other corrosive substances is common. |
| Gasket | NBR | Nitrile Rubber: The NBR gasket provides an excellent seal between different components of the strainer. It is resistant to oil and other chemicals commonly found in marine fuel and lubricating oil systems, ensuring a leak – free operation and preventing contamination. |
| Yoke | FCD450 | Nodular Cast Iron: The yoke is made of FCD450 nodular cast iron, which has higher strength and ductility compared to regular cast iron. This makes the yoke more resistant to deformation and cracking, enhancing the overall structural integrity of the strainer. |
| Plugs | – | Brass: The plugs are made of brass, a material known for its corrosion resistance and ease of machining. This ensures that the plugs can be easily installed and removed for maintenance purposes, while also providing a reliable seal to prevent oil leakage. |
