Petroleum Terminal Handling and Diesel Exhaust Fluid

4 L O A D I N G A R M O V E R V I E W Autolok™ • Provides extra protection against accidental release or uncoupling • Arms lock automatically with a positive click • If our exclusive Twin-Kam™ arms ever break, they are replaced FREE Kamvalok® • Economical cam and groove dry-disconnect coupler • Prevents spillage at point of connection/disconnection • Lever action closes flow at both ends of connection System DesignTips Line Sizing: As a general rule, it is recommended that the line velocity not exceed 15-20 ft/second (4.6 to 6.1 m/sec). The chart (right) shows recommended flow rates for different line sizes. Materials Materials and seals must be generally compatible with the product and its temperature during handling. Materials will typically match plant piping on which the arm is installed. Line Size Maximum Flow Rate by Line Velocity 15 ft. per second 20 ft. per second 2 150 GPM (568 LPM) 200 (757) 3 350 GPM (1,325 LPM) 450 (1,703) 4 600 GPM (2,271 LPM) 800 (3,028) 6 1,350 GPM (5,110 LPM) 1,800 (6813) 1 2 3 Plant Piping Orientations Several options are available depending on the plant-piping configuration. Upfeed Downfeed Horizontal Feed Right Handed Left Handed • Metals (standard): carbon, steel, stainless steel, aluminum • Seals (standard): Viton®, Buna,Teflon®, EPT and neoprene • Piping: schedule 10, 40, 80, seamless or welded, all flanged Added Weight Adding or reducing weight on an arm will affect the arm’s balance. Please specify all weight that will be added to or taken off arm when installed. Common additions include: • Insulation • Valving • Vapor Recovery Lines • Product Being Stored in Arm 4 Termination Connections Other Considerations: Valving – Valves are a commonly specified option. We can provide the specific valve to meet your needs. Note location and preferred type of valve required. SteamTracing – Loading arm can be easily designed to incorporate partial or full steam jacketing. High Level Shut-Off – Several options are available to help ensure that overfill condition is prevented. Grounding – Another important consideration when loading volatile products – several options are available to help ensure system is properly grounded. 5 Adequate Range of Motion • Can arm be easily accessed/stored? • Any possible interference/obstacles? • Adequate Flexibility to make connection? - Structural Steel - Overhead Pipe Access Equipment
