Product catalog summary

Ordering Specifications:
To select the appropriate rupture disc and holder, it is essential to determine operating specifications such as maximum allowable working pressure, operating pressure and temperature, vacuum/backpressure, cycle conditions, required flow rate, media, and molecular weight/specific gravity. Quality assurance documentation includes compliance with codes (ASME, ISO, etc.), special cleaning, packaging, tagging, temperature testing, and material test reports.

Rupture Disc Details:
The Standard Rupture Disc is a solid metal device designed for overpressure protection, featuring a full-opening design for optimal flow. It is suitable for systems operating up to 70% of the disc's rated burst pressure and is available in sizes from 1/4" to 30". Materials include Aluminum, Silver, Nickel, Monel, Inconel, and Stainless Steel. Options include ASME testing, liners, coatings, protective rings, vacuum/backpressure support, gaskets, and the B.D.I. Alarm System.

Holder Configurations:
Various holder types are available, including Insert Type, Full Bolted Style, Screw Type, and Union Type Holders, each designed for specific pressure and size requirements. Materials include Carbon Steel and Stainless Steel, with special materials available upon request.

Code Compliance:
Rupture discs can be manufactured to comply with ASME, ISO, DIN, EN, BSI, JIS, or other codes. The ASME Code Symbol Stamp is available for products meeting ASME Boiler and Pressure Vessel Code requirements. Certified flow performance data is available from Continental Disc Corporation.

Additional Features:
Protective liners and rings are available to shield the rupture disc from corrosive elements. Vacuum and backpressure supports are provided for systems requiring additional support due to thin materials or specific operating conditions.

Specifications:
The document outlines the specifications for rupture discs and associated components, emphasizing the importance of specifying operating conditions when subjected to vacuum or backpressure. The Continental Disc Corporation (C.D.C.) provides support designs tailored to these conditions.

Gaskets:
Gaskets are recommended when the seating surface of the holder is scratched or pitted to enhance sealing and prevent leakage. Teflon gaskets are standard, but other materials are available upon request for specialized applications.

B.D.I. Alarm System:
The Burst Disc Indicator (B.D.I.) Alarm System is crucial for immediate notification of overpressure relief. It uses a copper wire adhered to a Teflon membrane, which breaks when the rupture disc bursts, disrupting the electrical current and triggering alarms. The system is compatible with computer systems, resistant to corrosives, and operates over a wide temperature range. It is available for rupture discs in sizes from 1" to 30".

Continental Disc Holders:
Rupture disc tags are not attached for use in Screw Type or Union Type Holders unless specified. For more information, consultation with the factory is advised.

Pressure and Temperature Ratings:
The document provides tables with maximum pressure ratings for stainless steel and carbon steel ASME class flanges, as well as temperature limits for various materials. It highlights that burst pressures generally decrease with increasing operating temperatures.

Manufacturing Range and Burst Tolerance:
The manufacturing range is the allowable pressure range for a rupture disc, based on customer-specified burst pressure. Special reduced ranges are available upon request. Burst tolerance is applied according to ASME Code, with specific tolerances for different pressure levels.

Tables:
Several tables are included, detailing manufacturing ranges, burst tolerances, maximum temperatures for materials, and minimum/maximum pressures for standard rupture discs. These tables provide critical data for selecting and using rupture discs effectively.

Overview:
The document provides detailed information on various types of rupture disc holders and rupture discs offered by Continental Disc Corporation (C.D.C.). These devices are used for overpressure protection in systems, equipment, and vessels.

Types of Holders:

30° Insert Type Holders: Designed for installation within the bolt circle of ASME, DIN, or JIS class flanges. Available in Carbon Steel, 304, or 316 Stainless Steel.
Full Bolted Style Holders: Available in sizes from 1/2" to 30" for ASME, DIN, or JIS Class flanges. Standard materials include Carbon Steel and 304 or 316 Stainless Steel.
Screw Type Holders: Used in mini-systems with pressures up to 20,000 psig. Available for 1/2" Standard Rupture Discs with MPT inlet threads.
Union Type Holders: Designed for piping connections with burst pressures up to 6,000 psig for smaller sizes and 4,000 psig for larger sizes. Available with threaded or welded inlets and outlets.

Code Compliance:
Rupture discs can be manufactured to comply with various codes such as ASME, ISO, DIN, EN, BSI, and JIS. C.D.C. is accredited to use the ASME Code Symbol Stamp.
