CorrosionResistance

Guide

Safety through knowledge and performance.

ZOOK Enterprises provides the following corrosion resistance information to be used when specifying ZOOK Graphite Rupture Disks.

This simplifi ed guide offers compatibility with common corrosives. Where there is doubt about compatibility, a sample of ZOOK Enterprises graphite will be supplied on request for your on-site evaluation. Please contact the factory if you have any questions. For descriptions of DUPLEX and other product-related information, consult the ZOOK Product Catalog or web site at www.zook.cc

INTERCHANGING WITH OTHER MANUFACTURE’S PRODUCT

ZOOK’s manufacturing process utilizes synthetic graphite impregnated with a particular resin utilizing a proprietary process; therefore, it is not a safe assumption that different brands of graphite rupture disks are equal and interchangeable.

A graphite disk produced by ZOOK Enterprises should not be substituted for another manufacturer’s similarproduct for the following reasons:

• Each manufacturer uses a different grade of graphite. Each grade contains different percentages of voids or pores in the material.• These voids must be fi lled in order to make the disk impervious (leak tight). ZOOK is unique in that we use a phenolic resin to fi ll the pores.• The impregnant used to fi ll the voids is different among each manufacturer. Some manufacturers use resins other than phenolic types or they use a “proprietary processes” which have only been used in recent years as impregnates.• Depending upon the resin used and the application, a ZOOK disk will function properly without leakage or premature rupture where another manufacturer’s product may deteriorate, leak, or cause it to rupture. One example of where a ZOOK disk is superior, is with a Furan impregnated disk in an acidic application.

NOTES• The resin ZOOK uses has been in use in the chemical processing and related industries for over 60 years. The performance over those 60 years gives us the confi dence to use our disks in the applications that we recommend.• The phenolic resin used in ZOOK graphite disk is environmentally safe and is in compliance with FDA. Consult the factory for appropriate disk styles.

PROLONGED APPLICATION LIFE

• If prolonged application life is a goal, we suggest the following product enhancement:

Each disk should be ARMORED - Armor consists of a steel (carbon or stainless) ring surrounding the graphite portion of the disk. It allows for uneven pipe stresses to exist and not affect disk burst performance. It also greatly reduces the possibility for improper installation due to uneven torquing of fl ange bolts and prevents possible rim fracture at time of blowdown. It is required in toxic and primary fi re service and high burst ratings. Armor is strongly suggested in very low burst ratings.

CAUTIONAny information contained in this guide pertains exclusively to ZOOK Graphite Rupture Disks and cannot be applied to any similar product produced by other manufacturers. ZOOK Graphite Rupture Disks possess unique qualities and characteristics that offer long application life and superior resistance to cycling (fatigue) and corrosion.
