O PW% LOADING ARM OVERVIEW a I, company System Design Tips 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 2 150 GPM (568 LPM) 200 (757) differentiline sizes. 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) Plant Piping Orientations Several options are available depending on the plant-piping configuration. Upfeed Downfeed Horizontal Right Handed Left Handed Feed Materials Materials and seals must be generally compatible Metals (standard): carbon, steel, with the product and its temperature during stainless steel, aluminum handling. Materials will typically match plant Seals (standard): Fluorocarbon ， piping on which the arm is installed. Buna-N, PTFE, EPDM and Neoprene sPiping: Schedule 10, 40, 80， seamless or welded, Added Weight all flanged Adding or reducing weight on an arm will affect the arms balance. Please specify all weight that will be added to or taken off arm when installed. Common additions include: Adequate Range of Motion * Can arm be easily accessed/stored? Insulation Valving Any possible interference/obstacles? Vapor Recovery * Adequate Flexibility to make connection? Lines Structural Steel Product Being Stored in Arm Overhead Pipe Access Equipment Termination Connections Autolok * Provides extra protection against accidental release or uncoupling * Arms lock automatically with a positive click o 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 e Other Considerations: Valving Valves are a commonly specified option. Specific valves can be provided to meet your needs. Note location and type of valve required. Steam Tracing 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 conditions are prevented. Grounding Another important consideration when loading volatile products several options are available to help ensure system is properly grounded.
