Variable Spring Hangers Designed for an Upstream and Valve Project in Thailand

PT&P designed and manufactured these variable spring hanger assemblies for an upstream and valve project in Thailand. The variables clamp sizes range from 6″ to 12″ diameter with installed heights ranging from 6-8/8″ to 12-1/4″ from the structure to the center of the pipe. The B-Type pipe hanger assembly uses coil springs to support the load and allow for some movement. They are furnished with one lug welded to the top of the spring casing which allows the assembly to be suspended from structural members for pipe support. All forty-seven variable spring supports were quality checked with a 100% spring coil deflection test and a load cell calibration to set the assemblies at the prescribed installed load.

Piping Technology & Products designed and fabricated 107 variable spring hanger assemblies for an Oil Sands Expansion Project in a central processing facility in Canada. We fabricated these C-type variable springs from hot-dipped galvanized carbon steel. The design loads range from 3,343 lb. to 3,417 lb., and each assembly underwent a series of tests and detailed quality control inspections prior to shipment.

27 B-Type Variable Spring Supports Designed for an Oil Refinery

PT&P designed and manufactured 27 B-Type variable spring supports for an oil refinery in Louisiana. The spring cans, rods, welded beam attachments, turnbuckles and clevises are fabricated from carbon steel. The spring cans have a 12-3/4″ diameter and measure 290″ from the bottom of the steel to the connection of the pipe. They were designed for 2″ of vertical movement and operating loads between 24,375 and 27,500 lb.

Variable Spring Hanger and Pipe Clamp Assemblies Designed for a Cogeneration Plant in Canada

These variable spring hanger and pipe clamp assemblies were custom designed for pipes ranging from 6″ to 20″ diameters at a co-generation plant in Canada. The spring can, threaded rods, weldless eyenuts, welded beam attachments and Fig. 80 pipe clamps were fabricated from hot-dipped galvanized carbon steel. The assemblies are capable of an overall load of 10,790 lb. with a total travel of 1/2″. A total of 21 spring hanger and clamp assemblies underwent standard load and travel testing.

Variable Spring Supports for a Gas Storage FacilityVariable Spring Supports for a Gas Storage Facility

A total of 90 variable spring supports were designed and manufactured to support pipe lines in a gas storage facility in Abu Dhabi. The pictures above show PTP-4 Double Spring B-Type, PTP-6 Triple Springs B-Type, PTP-1 Triple Springs D-Type, and PTP-4 Double Springs F-Type, (also known as F-Cans). Load capacities range from 1,000 lb. to 45,000 lb., and movements range from 3/8″ to 3″. A two-layer custom paint was applied over the hot-dip galvanized finish to protect against a severely corrosive environment. Travel stops were chained to the spring can housing, so they can be reused during plant shutdowns. Load and quality assurance tests were performed on all the supports prior to shipment.

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

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.

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.
