It is essential you ensure the ANSI rating150LB up to 250NB:- 285 PSIyou order is suitable for the maximum pressure of your service. Note Class 150 300NB and 300 Class 150NB & 200NB are300LB up to 125NB:- 740 PSInot full ANSI rated see CWP table above. For temperatures to 300C we would offer Borosilicate or mica glass.We also150LB 250NB to 300NB:- 250 PSIsupply borosilicate glass if application is for chemical service such as ketones, halogenated hydrocarbons, esters, aromatic300LB 150NB to 200NB:- 500 PSI (Table H)hydrocarbons, aliphatic hydrocarbons, acids, amines, high concentration of alkalis & any other fluids not compatible with600LB 15NB to 50NB:- 1440 PSIcarbonated perspex. Please state your application. If a higher pressure is required you must specify in writing on your inquiry and your order.The catalogue is general in its nature and design and can vary at any time.This catalogue is to be used as a guide only.6 FLOWTURN - Strainers and Sight Glasses'
