Furnace Spring Assemblies up to 13,000 lbs. for a Chemical Refinery

Piping Technology and Products, Inc. designed and manufactured furnace spring assemblies for a chemical refinery in Saudi Arabia.  Each pipe hanger assembly consists of a variable spring, rod, clevis, hex nuts, and pipe attachments. Unlike other variable springs which are designed to have bolted housings, these furnace springs are designed for spring coils with a customer specified spring rate installed in a welded housing. The sizes of these Fig. PTP-2 and Fig. PTP-4 ranged from 90-170, with a total travel of 1 1/4" to 5", and loads varying from 850 lbs to 13,300 lbs.

Furnace Spring Assemblies up to 13,000 lbs. for a Chemical Refinery

Prior to the final welding, trial fit-up and cycle test were performed to ensure unrestrained movement throughout the designed travel range. The spring assemblies were then calibrated to determine the exact spring rate prior to shipping.

9200 lb. Load Type “E” Constant Hanger Assemblies

PT&P designed and manufactured forty PTP 200- type “E” constant hanger assemblies with pipe sizes ranging from 36” to 62” for an oil refinery in Canada.  These constant hanger assemblies are designed to support and allow vertical movement of the field pipe during thermal expansion. The constants have a load capacity of 2800 lbs. to 9200 lbs. and a 3”-7” travel range. To assure quality, standard load testing was performed on the constants prior to shipping. The assemblies’ components consist of a constant load hanger, a rod and a clamp. The constants are fabricated from ASTM A36 carbon steel and the rod and clamp were manufactured from ASTM A240, Gr. 304 stainless steel.

950 lb. load C-type Constants

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.
