Variable Spring Supports for a Furnace application at an Ammonia Plant

Type: Variable Spring Supports
Material: Carbon Steel | Red-Oxide Primer | 304 SS
Design: 3,000 lb./in.
Testing: Load Test

PT&P custom designed variable spring support assemblies for a furnace application at an ammonia plant. The furnace springs are fabricated from carbon steel and painted with a red-oxide primer to help prevent corrosion. The pipe clamps are fabricated from 304 stainless steel. They are designed to support a cold load of almost 3,000 lb./in. while operating in an area where temperatures are higher than ambient. There were a total of 173 assemblies fabricated for this project, 152 variable hangers, 3 constant spring supports, 6 ball joint rigid struts, and 12 rigid rod hangers. Special load tests were performed prior to shipping.

Variable Spring Supports Designed for a Furnace in Trinidad

Variable Spring Supports Designed for a Furnace in Trinidad

Type: F-Type Variable Spring Supports (Furnace Springs)
Material: Carbon Steel | Red Oxide Primer
Design: Movement: 1/2 “| Load: 398 lb. | Spring Rate: 84 lb./in.
Testing: Standard Spring Rate & Calibration Tests

PT&P designed and manufactured these F-Type variable spring supports for use in a furnace at a facility in Trinidad. We manufactured these furnace springs for an operating load of 398 lb., a movement up to 1/2″, and a springs rate of 84 lb./in. They are fabricated from carbon steel with a red oxide primer coating to protect against corrosion. Customer specifications required a modified, installed height, while maintaining the spring rate, operating load and install load. In order to accomplish this, PT&P designed, manufactured and attached, to each spring, a pedestal to accomplish the increased installed height.

Variable Spring Supports Designed for a Furnace Application in Oklahoma

Type: Variable Spring Supports
Design: 1,765 lb. Load | +/- 5% Spring Rate
Material: Carbon Steel with Red Oxide Primer
Testing: Standard Spring Rate & Calibration Tests

PT&P custom designed variable spring supports for a furnace application at a Nitrogen Facility in Oklahoma. The furnace springs are fabricated from carbon steel and painted with a red-oxide primer to help prevent corrosion. The spring supports are designed to support loads up to 1,765 lb. With a spring rate calibrated to be within +/- 5% of the theoretical value.

300 Variable Spring Supports Designed for a Furnace Application at a Methanol Processing Facility

300 Variable Spring Supports Designed for a Furnace Application at a Methanol Processing Facility

PT&P designed and fabricated 300 variable spring supports for use in a furnace within a methanol processing facility in Mexico. We manufactured the ”housing” of these variable springs using seamless pipe (in order to prevent the springs’ coils from rubbing against the ”weld seam” of a standard pipe) so that the exact spring rate (+/- 5%) can be calculated without discrepancies or variations. The reason that an accurate spring rate is important is because furnace springs function as a ”scale” in order to determine the weight of the radiant coils within the unit. These springs are coated with red oxide primer to protect against corrosion. We manufactured these furnace spring assemblies for an operating load of 1,036 lb. and a movement up to 8 1/2″. Each spring is traceable to test data and tagged with its’ unique spring rate along with other standard information use for identification.

Furnace SpringsJoin us for this Webinar focusing on the unique design aspects of pipe supports and expansion joints operating in furnace applications. See how these non-standard designs impact the overall construction and fabrication processes. Learn the differences between standard supports and those specifically used in furnace applications. View the in-depth testing processes and learn what to watch for during inspection and maintenance intervals.

The featured presenter, Jerry Godina has over 15 years experience as a pipe support designer and manages PT&P’s engineer training development program. He also inspects existing supports, consults on site remediation projects and oversees installation on a regular basis.

 

Variable Spring Supports Custom Designed for a Furnace Application in an Ammonia Plant

Variable Spring Supports Custom Designed for a Furnace Application in an Ammonia Plant

PT&P custom designed variable spring supports for catalyst tubes in a furnace for an ammonia plant in Canada. The furnace springs are fabricated from carbon steel and painted with a red-oxide primer to help prevent corrosion. This project required special coils that were within +/- 5% of the calculated spring rate. Over 245 springs underwent calibration test prior to shipment. PT&P has been supplying furnace springs for over 25 years and can customize them to meet your specifications.

112 Custom Variable Springs Designed for a Furnace Application in Venezuela

112 Custom Variable Springs Designed for a Furnace Application in Venezuela

112 custom variable springs designed for a furnace application for an oil refinery in Venezuela. The furnace cans are designed from carbon steel and painted with red oxide primer to prevent corrosion when exposed to high temperatures. The sizes of these figures PTP-6 and PTP-8 range in length from 25″- 39″, with a total travel of 0.1″- 1.821″ and loads varying from 430 – 681 lb. A load test to confirm the spring rate was conducted on each assembly prior to shipment.
