We just posted a new video that discusses our spring loading procedure of standard variable springs. Watch our field service representative talk you through the process of loading a variable spring before it is shipped.
PT&P fabricated pre-insulated pipe supports from galvanized carbon steel designed for a 49″ diameter pipe and temperatures in excess of 1600°F. The insulation is 12″ thick and composed of lime, silica and reinforcing fibers. This type of insulation features exceptional strength and extremely low water absorption. It is essentially dust-free, contains no asbestos and is a very good material for structural insulation inserts. This “hot shoe” will be used in a cat cracker unit at a refinery in Alabama.
These PT&P 200 series constants are fabricated from A36 carbon steel. The 200-A constants measure 18.5″w x 20″H x 65″L and will support a 22,200 lb. load. They are modified to avoid interference with the structure by shortening the frame. The 200-C constants measure 18.5″w x 29″H x 80″L and will support a 32,000 lb. load. The constants have specially fabricated lugs to allow for a 3 ton trolley to connect with it.
