21 5. FlameArrestingVentCap

22 SERIES 670 / 6670 End-of-Line Deflagration Flame Arrester Suitable for use with vapors equivalent to NEC 500 Group D, IEC Group IIA PROTECTOSEAL Sizes 1" through 4" Listed by Underwriters Laboratories in 1" and 2 sizes Suitable for use with vapors equivalent to NEC 500 Group D, IEC Group IIA Vertically mounted, parallel plate-type flame arrester Protects against fire Minimizes pressure drop under normal operating conditions Easy inspection and maintenance Factory inspected prior to shipment Available in Aluminum and Stainless Steel OBJECTIVE The Series 670/6670 Flame Arresters are designed to provide flame stopping protection for a tank s vapor space when mounted to the end of a tank nozzle leading directly to atmosphere. The arresters prevent a flame front generated by an unconfined deflagration occurring outside the tank from propagating into the vapor space. VAPOR GROUPS The arresters are intended for use with vapors equivalent to Group D of the National Electric Code (NEC 500), IEC Group IIA. For arresters suitable for use with NEC Group C, IEC Group IIB3, please refer to Protectoseal Series 670E. TECHNIQUE The arrester is mounted on the end of a vent pipe from the tank. Vapors are allowed to escape into the atmosphere and air can be drawn into the tank through the specially designed flame arrester grid assembly. If an ignition source outside the tank is encountered, the flame arrester provides protection for the tank contents. SPECIAL FEATURES Easy Inspection, Installation and Maintenance. Design and light weight of unit permit easy, convenient handling for inspection, installation and maintenance. The weatherhood is readily removable by loosening just a few extra large wing nuts. Automatic Condensate Drainage. Vertically mounted, circular plate-type flame arrester is employed for self-drainage of condensate. This prevents accumulation of condensate subject to freezing and consequent clogging of the arrester under low temperature conditions. Positive Flame Arresting. The Series 670/6670 employs a circular-plate, precisely-spaced, type flame arrester to protect tank contents by preventing the propagation of fire into the tank. Precision embossings on alternate plates provide correct air-spacing for flame arresting function. Plates are fabricated from 1 16" to 3 32" heavy gauge metal, depending on material of construction, to resist distortion and bending during cleaning. Sizes Available. 1", 2", 3" and 4" have standard NPT female threaded connections. Adapter flanges are available in these sizes. Refer to dimension chart on reverse for flange connection details. Refer to Series 670E for 6 size. Test Lab Listings. Listed by Underwriters Laboratories (UL) in 1" and 2 sizes. For arresters that meet ATEX Directive 94/9/EC Standards EN & ISO 16852, please refer to Series 670E. PRO-FLOW III Sizing and Selection Software. Use PRO-FLOW III to select the correct size unit for pressure and vacuum relief calculated in accordance with API 2000, ISO 28300, NFPA 30 and OSHA Quality Assurance. Each unit is inspected to meet Protectoseal s high standards prior to shipment. CONSTRUCTION A comprehensive range of materials is offered as shown in the chart below.

24 6. EmergencyVentCap

25 Model 244 Emergency Vents 4-inch SPECIFICATION SHEET The Fig. 244 Emergency Vent (pressure relief only) Series is used on aboveground storage tanks, as a code requirement, to help prevent the tank from becoming over-pressurized and possibly rupturing if ever exposed to fi re. The vent must be used in conjunction with a normal vent. Correct application of this vent requires proper vent size and selection for the tank system in order to meet the specifi c venting capacity requirements. The new design increases protection against weather, improves manufacturability and helps limit and control dust accumulation. Code Compliance API 2000; International Fire Code; National Fire Code of Canada; NFPA 1, 30, 30A, 31, 37, 110; PEI RP200; PEI RP800; Underwriters Laboratories Inc. UL-142, UL-2085, UL- 2244; Underwriters Laboratories of Canada CAN/ULC S601-07, CAN/ULC S602-07, CAN/ULC S Fig. 244OF Additional References NFPA 30, UL 142, Morrison Venting Guide Fig. 244OM WARNING: DO NOT FILL OR UNLOAD FUEL FROM A STORAGE TANK UNLESS IT IS CERTAIN THAT THE TANK VENTS WILL OPERATE PROPERLY. Morrison tank vents are designed only for use on shop fabricated atmospheric tanks which have been built and tested in accordance with UL 142, NFPA 30 & 30A, and API 650 and in accordance with all applicable local, state, and federal laws. In normal operation, dust and debris can accumulate in vent openings and block air passages. Certain atmospheric conditions such as a sudden drop in temperature, below freezing temperatures, and freezing rain can cause moisture to enter the vent and freeze which can restrict internal movement of vent mechanisms and block air passages. All storage tank vent air passages must be completely free of restriction and all vent mechanisms must have free movement in order to insure proper operation. Any restriction of airfl ow can cause excessive pressure or vacuum to build up in the storage tank, which can result in structural damage to the tank, fuel spillage, property damage, fi re, injury, and death. Monthly inspection, and immediate inspection during freezing conditions, by someone familiar with the proper operation of storage tank vents, is required to insure venting devices are functioning properly before fi lling or unloading a tank. 570 E. 7th Street, P.O.
