Chemtrol 6551-H Socket Flange
This Chemtrol 6551-H fitting is a 3/4 inch socket flange designed for Schedule 80 piping systems. It connects solvent-weld pipe to flanged equipment or valves in industrial fluid-handling installations. The polyvinylidene fluoride body handles aggressive chemicals at elevated temperatures. The red colour coding helps identify the line service quickly.
Pressure rating and temperature limits
The flange carries a 150 psi maximum operating pressure from 73 to 280 degrees Fahrenheit. A 1360 psi burst rating provides a wide safety margin for pressure spikes. Class 150 bolt pattern with four 5/8 inch bolt holes on a 2 3/4 inch bolt circle matches standard companion flanges. Schedule 80 wall thickness ensures mechanical strength for demanding service.
Installation requirements and system fit
Socket end accepts 3/4 inch Schedule 80 pipe for solvent cement joining without threading tools. The 3 7/8 inch outside diameter and 3 3/4 inch overall length fit compact piping layouts. Four bolt holes allow straightforward alignment with mating flanges and gaskets. Polyvinylidene fluoride construction resists corrosion, reducing maintenance in harsh chemical environments.
