The relationship between the SDR and the pressure rating is given by Lames formula for the hoop stress in thick wall cylinders: s = P(dn - en) / 2 en This can be rearranged as; s = P (SDR - 1) / 2 Wheresis the maximum hoop stressPis the internal pipe pressure. The hoop stress...
If a device has a rating of IP68, for example, the device will be dust-tight and protected against long periods of immersion in water under pressure. This example is both dust-tight and watertight according to the standards set up in the IP rating. ...
How Pressure Rating Works A stainless steel pipe that is 1/4-inch thick will not be able to sustain as much pressure as a 1/2-inch thick piece of stainless steel pipe of the same length. A pressure rating states the maximum allowable stress value of a material at a specific temperature...

SPEED RATING A speed rating can help you determine which tires will work best for your vehicle. Find out how to interpret these ratings so you can choose tires wisely. Tire speed rating is the top speed a tire can safely keep over time. View our tire speed rating chart and visit your ...
Why Is IP Rating Important? Ingress Protection (IP) measures the level of protection that an enclosure provides electrical equipment with a rated voltage that doesn’t exceed 72.5 kiloVolts (kV). The IP rating is crucial to understanding a product’s resistance level to water, dust, debris, et...
An IP rating with a 9 in the second digit indicates that the enclosure is completely protected from the intrusion of water and moisture when submerged under heavy pressure. Based on this information, it’s safe to assume that enclosures with a higher IP rating are better than their ...
is carefully curated to ensure it is highly resistant to scratches and damage. For even greater protection the Galaxy Watch6 Classic also comes with an IP681water and dust rating. This means it can withstand being in the water for up to 30 minutes, at a depth of 1.5 metres without b...
This ratio indicates that the higher the degree of financial leverage, the more volatile earnings will be. Interest is usually a fixed expense so leverage magnifies returns and EPS. This is good when operating income is rising but it can be a problem when operating income is under pressure. ...
Smith's employer to remit a portion of his salary for a certain amount of time until Smith's tax obligation is fully paid. Because garnishments are usually the last resort to collect debts and show a debtor's unfavorable repayment history, they can harm an individual’s credit rating. ...
