ANSI Flange Pressure Rating ke eng?

The li-flange tsa sehlopha sa ansi pressure rating refers to the maximum pressure a flange can withstand without failure during operation. This rating is determined based on the flange’s material, size, and the class or pressure level defined in ANSI standards. Flanges are available in different pressure classes, each with its own limits, which are crucial for ensuring the flange can handle the operating conditions of a given system.

The pressure rating is typically indicated in terms of pounds per square inch (psi) and is associated with specific temperature ranges. For example, ANSI flanges with a class rating of 150, 300, or 600 correspond to different maximum pressure capacities, which must be matched with the operating conditions of the system.

Litlelase tsena li etsa qeto ea khatello e phahameng e lumelletsoeng ea ho sebetsa (MAWP) ho latela boholo ba flange le thepa e sebelisoang.

Class 150 flanges, for instance, are typically used in systems with moderate pressure requirements, while Class 600 flanges are designed for high-pressure systems. As the class number increases, so does the flange's ability to handle higher pressures. However, it’s essential to consider more than just the pressure rating—temperature and environmental conditions also play a role in determining the overall strength and safety of the connection.

Lintlha tse Amang ANSI Flange Pressure Ratings

While the pressure class provides an initial estimate of a flange’s capabilities, several factors can affect the actual performance of the flange in a system. These factors include:

Mofuta oa Boitsebiso: Thepa eo flange e entsoeng ka eona e susumetsa haholo tekanyo ea khatello ea eona. Mohlala, li-flange tse entsoeng ka tšepe ea k'habone hangata li na le litekanyetso tse tlase tsa khatello ha li bapisoa le tse entsoeng ka tšepe e sa hloekang kapa lialloi tse etselitsoeng maemo a khatello e phahameng.

Temperature: Temperature is one of the most important considerations when evaluating a flange's pressure rating. Most flanges are rated for specific temperature ranges. Higher temperatures can weaken materials and reduce the maximum allowable pressure the flange can handle. Always refer to the pressure-temperature charts provided by ANSI or the manufacturer to ensure you select a flange rated for your operational temperatures.

Boholo ba Flange: Bophara le botenya ba flange le tsona li phetha karolo ea tekanyo ea khatello ea eona. Li-flange tse kholo ka kakaretso li na le matla a phahameng a khatello, empa moralo oa tsona le thepa e sebelisoang li ntse li tlameha ho lumellana le litlhoko tsa tsamaiso.

Bolt Torque: Proper bolt torque is critical for ensuring the integrity of the flange under pressure. If bolts are not tightened adequately, the flange may not create a proper seal, which could lead to leaks or even failure under pressure. Therefore, it’s essential to apply the correct bolt torque based on the flange size and pressure rating.

Account for Safety Margins: Always allow for a safety margin when selecting flanges. It’s best to select a flange with a pressure rating that exceeds your system's maximum pressure to account for unforeseen surges or fluctuations in pressure.
