Hydraulic SAE Flanges: Design and Construction
The design and construction of SAE Hydraulic flanges involve precise methods to create a robust and reliable connection for tubes, hoses, pipes, and other fittings. These flanges are designed to conform to SAE J518 and ISO 6162 standards, ensuring a high-pressure, leak-free connection.
They are typically made of carbon steel, offering strength and durability for a range of applications. Variations such as the SAE split and SAE blind flanges are available, each catering to specific connection needs.
The complete set, including flange adapters, clamps, and block fittings, ensures a secure fit and optimal performance. Notably, blind flanges provide a means to block off the 4-bolt flange port, contributing to the overall versatility of the system.
Industrial Applications of SAE Flanges
Building upon their robust design and construction, SAE Hydraulic flanges’ versatility extends to a wide range of industrial applications. Their high-pressure resistance, with a continuous pressure level of 6,000 PSI, makes them suitable for many hydraulic systems.
The flanges, designed under two codes, code 61 and 62, are utilized for different pressure ratings. The split flange design allows easy disassembly, vital for maintenance and modifications. SAE Hydraulic flanges accommodate hoses, with a secure seal ensured by an o-ring. Welding connections, including socket and butt weld, offer reliability and durability. The socket weld, in particular, is a prevalent choice for pipe diameters under 2 inches.
Thus, the SAE flange’s adaptability, coupled with its robust construction, supports its broad industrial utility.
Strict Standards for SAE Flange Manufacturing
Adhering to rigorous standards in SAE flange manufacturing is paramount, considering the critical role these components play in diverse industrial applications. The manufacturing process is governed by ISO 6162/SAE J518 specifications, ensuring high pressure and temperature resilience.
Flanges are engineered with different thread types such as UNC, NPT, and BSPP to accommodate versatile connection needs. The flat face of the flange is meticulously designed for cap screws, ensuring a secure and tight junction.
The types of connection offered include threaded end and welding end, each designed for specific applications and pressures. All these features are forged under strict protocols to withstand high pressures, thus solidifying the flange’s crucial role in industrial settings.
Stainless steel SAE hydraulic flanges are a type of flange that meets SAE J518 and ISO 6162 standards. They are designed to provide leak-free connections for high-pressure and large-size hydraulic systems. Available in sizes from 3/8″ to 5″, stainless steel SAE hydraulic flanges can be connected using butt weld, socket weld, or threaded connections (BSPP, NPT, metric, or JIC). Code 61 flanges have a working pressure of up to 210 Bar (3000 PSI), while Code 62 flanges can withstand up to 420 Bar (6000 PSI). Stainless steel SAE hydraulic flanges are widely used in industrial hydraulics, mobile hydraulics, and shipbuilding. They offer several advantages over other types of connectors, including higher pressure resistance, better shock and vibration resistance, and easier installation in confined spaces.
