PT&P recently designed and manufactured sixteen PTP-200 C-type constants modified to fit in constricted areas near a furnace of a chemical facility.  These constants are designed to travel from 5 1/2” to 19” and are specified to carry loads ranging from 245 to 924 lbs. They were fabricated from A36 plates with 4140 pins. Due to the proximity of the pipes and other equipment, the front part of the constant frame was cut to allow the pipe to move freely. Load and travel testing was performed to ensure quality and precise performance.
