DPE / Drip Pan Elbow |
 |
The use of a drip pan elbow is highly recommended for steam service safety valves. When attached to a safety valve outlet, these elbows collect and remove condensate as well as isolate the valve from discharge piping stresses. Elbows through 4" feature female NPT threads and connect to the valve outlet by means of a close nipple. The 6" and 8" elbows have integral 125# ANSI B16.1 flanges and bolt directly to the valve outlet. Sizes: 3/4" through 8", flanged and threaded models. Material: Gray iron ASTM A126 class B. Finish: Black phosphate or black paint coating.

ASME UV Sec VIII, 1/2" to 1"
To achieve topmost performance and maximum service life, it is necessary to maintain a proper pressure margin between the set pressure of the safety relief valve and the operating pressure of the equipment. The minimum recommended operating pressure margin for this type of safety relief valve is 10 psi or 25% of the operating pressure, whichever is greater. |
