Sterling 882.00379.00 manual Multiple Line System Piping Considerations

∙You can attach a quick-change or standard tube coupler to vinyl flex hose by inserting a stub of hard tube into the hose and securing it with a hose clamp. Be sure enough tube extends from the hose to properly install the quick-change or coupler. Make sure that you put clear silicone caulk around adjoining tube seams for exterior bolted couplers.

∙If you use stainless flexible material hose, the material flow must be in the direction as indicated by the arrows on the hose. Material direction is not critical with vinyl flex hose.

∙Bring all truck fill lines to a central location, such as a silo, unless otherwise specified.

∙All rail car manifold Y-tubes must be installed with a ten-degree (10º) downward slant from horizontal on the leg section. Make sure that space between rail car manifold Y-tubes are fifteen feet (15’/4.5 meters) on center to allow proper alignment between rail car discharge ports and the manifold Y-tubes.

∙A plug must be put in the last sequence T valve on the vacuum header to prevent vacuum loss. If atmospheric valves are used, you must terminate the vacuum line at the last atmospheric valve.

Multiple Line System Piping Considerations

∙Multiple line systems have separate material lines for each material to allow different types of materials to be conveyed.

∙Multiple line systems have separate pickup devices for each vacuum hopper.

∙Materials are often loaded from beside the processing machine from gaylords, grinder takeoffs, and storage bin takeoffs.
