Questions about this item

Will the red brass nipple need replacement due to corrosion or wear under normal use?

The seamless red brass construction to ASTM B43 resists corrosion in air, natural gas, oil, potable water and steam service, so routine replacement is not expected.

What pressure or temperature limit will be reached first during continuous high-temperature steam service?

The maximum steam pressure is 282 psi at 450 °F, while the maximum operating temperature is 400 °F; the temperature limit is reached first.

How much heat does the nipple radiate when carrying steam at the rated pressure all day?

At 282 psi and 450 °F the nipple will become very hot; insulation or guarding is recommended to protect personnel and nearby components.
