SAE flange ISO 6162 standard classification society certification refers to hydraulic flanges that comply with the SAE (Society of Automotive Engineers) hydraulic flange standards and ISO 6162 standards, and have been certified by the classification society.
SAE flange is a connecting device used to connect pipelines and components in hydraulic systems. It is usually made of steel and can withstand high pressure and high flow of liquid transmission. The SAE hydraulic flange standard was developed by the Society of Automotive Engineers to ensure the safety and reliability of hydraulic systems.
ISO 6162 is a hydraulic flange standard developed by the International Organization for Standardization, which specifies the dimensions, connection methods, and performance requirements of hydraulic flanges to ensure that flanges produced by different manufacturers can be interchanged.
The ISO 6162 standard is the standard for hydraulic flange connections, which, together with standards such as ISO 23045 and ISO 19973, constitutes the international standard for hydraulic flange connection technology and products. Specifically, it includes the following content:
1. ISO 6162-1: Hydraulic flange connection technology – Flange joints and O-ring seals – Part 1: Dimensions, performance and requirements
2. ISO 6162-2: Hydraulic flange connection technology – Flange joints and O-ring connections – Part 2: Additional requirements
3. ISO 6162-3: Hydraulic flange connection technology – Flange joints and O-ring seals – Part 3: Metrological control of flanges, clamps, and O-ring seals
4. ISO 6162-4: Hydraulic flange connection technology – Flange joints and O-ring seals – Part 4: International reserved parameters and testing procedures for flanges, clamps, and O-ring seals
These standards specify the dimensions, performance, requirements, as well as additional requirements, metrological control, and internationally retained parameters for SAE flange connections, and are commonly used flange connection standards in hydraulic systems.
Classification Society certification refers to products certified by the Classification Society that comply with specific offshore ship engineering standards and requirements. Classification societies usually verify, inspect, and recognize ships and related equipment to ensure that they comply with relevant international and industry standards and have safety and reliability.
SAE flanges are widely used in marine engineering ships. Hydraulic flange connection is a reliable connection method for hydraulic systems, and its main advantages include:
1. High reliability: SAE flange connections have good sealing performance and repeated reliability, which can withstand high pressure and high flow working conditions, ensuring the safe and stable operation of the system.
2. Easy maintenance: The SAE flange connection has a modular design, which is easy to install and disassemble, and facilitates system maintenance and replacement.
3. Strong adaptability: SAE flange connections have multiple sizes and types to choose from, which can meet different work requirements and installation environments, improving the flexibility and adaptability of the system.
On offshore vessels, SAE flanges are commonly used for the following applications:
1. Hydraulic power system: including the connection of hydraulic equipment such as hydraulic pump stations, control valve groups, and hydraulic cylinders.
2. Steering gear system: Converts hydraulic power into control force of the steering gear, used to control the rudder angle of the ship.
3. Ship lifting system: The connection of hydraulic components such as hydraulic cylinders and hydraulic motors, used to achieve control of lifting, hoisting, and ship power devices.
4. Marine hydraulic tools: connections for hydraulic tools such as hydraulic shear machines and hydraulic pliers, used for ship maintenance and operations.
In general, SAE flange plays an important role in connecting and controlling the hydraulic system on offshore vessels, improving the reliability, flexibility and safety of the system.
Therefore, SAE flange ISO 6162 classification society certification refers to hydraulic flange products that have been certified by the classification society to comply with SAE flange standards and ISO 6162 standards. This certification ensures the safety, reliability, and applicability of the product in hydraulic systems, and is particularly suitable for applications in fields such as ocean ship engineering.
