PT&P custom-designed and manufactured constant spring supports for a mainstream system at a power plant in Egypt. The constants include alloy clamps designed for a 900 mm (approximately 36″ dia.) pipe. They are 48″ H x 57″ L x 24″ W with 7-1/2″ total travel from the cold position. We also supplied alloy clamps designed for an operating temperature of 1070°F. The constants are fabricated from A36 carbon steel and include a hot-dip galvanized protective coating. They are designed for an operating load of 24,712 lb. The constants have been modified to accommodate a specialized spring coil and modified casing in order to fit the existing space or envelope. Standard travel and load tests were performed prior to shipping.

Constants can be used with rollers, travelers, or slide plates to accommodate lateral or axial movement in the pipeline system in plants such as solar, geothermal, soybean crushing, ethanol, and other green energy facilities. Our company and its subsidiaries work with over 90% of the leading green energy providers in the world.

Our Field Service team, along with our pipe support engineers and designers, can also conduct inspections of existing supports, provide consultation on-site remediation, and oversee installation on both a short-term and long-term basis catering to facilities worldwide. So whether a “grassroots project” or an existing plant that has been in service for years, we offer cost-effective products and services.

Variable Spring Supports Designed for a Furnace in Trinidad
April 11, 2023

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 spring rate of 84 lb./in. Customer specifications required a modified “installed height” while maintaining the spring rate, operating load and installation load. In order to accomplish this, PT&P designed, manufactured, and attached, to each spring, a “pedestal” to accomplish the increased installed height. They are fabricated from carbon steel with a red oxide primer coating (instead of a hot dipped galvanized) to protect against corrosion. Our standard hot-dipped galvanizing is not suitable for high temperatures because the zinc used in the galvanizing process can melt and cause damage to surrounding pipes and equipment. We also offer several other coatings for high-temperature applications.

We offer a wide range of modifications to our standard variable springs, from stainless steel units used in Food Processing plants and facilities which operate at Sub-Zero temperatures to units designed for use in high-temperature applications often found in refineries, fertilizer, and chemical plants. Some applications include hydrogen reboilers and radiant coils in gas vent heater systems. Our team of sales, engineering, and manufacturing offers a unique source of experience and knowledge unmatched in our industry.

In a Furnace application, both variable and/or constant spring hangers are utilized to support piping and equipment. In the past year, we have provided constant furnace springs for some of the largest refineries in the Americas. We replaced a 25-year incumbent design with a smaller envelope at a lower cost than any other offering in the market with our newly designed nano-constant. The project requirements were stringent in terms of load deviation requirements of 3% of all catalyst tube springs. We provided over 350 furnace springs in less than six months’ time from our manufacturing facility in Houston, Texas. To expedite the manufacture and shipment of springs, we built a new test machine in order to conduct tests more quickly, as every unit is tested before being shipped to the job site.

If you need assistance or are interested in scheduling a virtual or in-person training specifically on pipe supports and expansion joints for furnace applications, reach out as we are always available 24×7 via our emergency service or just send an email to info@pipingtech.com.

Compact Spring Supports Designed For An Oil Refinery In Minnesota

These compact spring supports were custom designed for an oil refinery in Minnesota. Typically, compact spring supports are used to support large loads but small movements relieving process equipment nozzles from overloading. In this case, the springs are designed to support loads of 5,605 lb., 4,747 lb. and 1,250 lb. and movements of 0.133” and 0.029” upward and 0.199″ downward, respectfully.

Compact spring supports utilize engineered Belleville (disc spring) washers. Since these spring supports contain disc springs, both the support housings and the springs contained in the housings are made from 304 stainless steel. Corrosion resistance is significantly increased by using this combination. Glass coatings can also be applied to both the housing and springs to make the support system virtually impervious. Each assembly underwent load testing prior to shipment.

Constant Assemblies Custom-Designed For Hot Service At A Leading Plastic Manufacturing Plant In North Carolina

Type: Custom-Designed Constant Spring Supports
Size: PTP-100 B-Type | 16” x 24” x 30”
Material: A36 Carbon Steel | Hot-dipped Galvanized| Epoxy Coating
Design: Load Range: 2,280 lb. to 7,143 lb. | 2″ Total Travel
Testing: Q.C. Inspection | Load and Travel Tests

PT&P custom-designed Constant Spring Support with travel stop adjustment rods for a manufacturing company. We “re-created” the design of constants sold years ago by our now sister company, Fronek Anchor/Darling. The constants needed to fit the “envelope” or space of the original constants sold to this client for an application in an existing plant. The constants were fabricated from A36 carbon steel, hot-dipped galvanized, and painted with an epoxy coating. The assemblies are designed for an operating load ranging from 2,280 lb. to 7,143 lb. with 2″ of total travel. Standard load and travel test and Q.C. inspections were completed prior to shipment to North Carolina.

We have a great deal of experience manufacturing constant spring supports similar to that of existing constants if needed to fit existing space limitations. We can also refurbish constants manufactured by competitors if the units are repairable. So whether the constants are for large duct systems in power and refining plants or focused around renewable, carbon-neutral plants, we can assist our clients to find a cost-effective solution.

Bronzphite® Slide Plate Assemblies Designed for an Oil Refinery in Canada
February 21, 2023

Bronzphite® Slide Plate Assemblies Designed For An Oil Refinery In Canada

Type: Bronzphite® Slide Plate Assemblies
Size: 1/2” x 4” x 4” | 1/2” x 7-1/2” x 7-1/2”.
Design: 1100°F Operating Temperature | 5000 PSI Load
Material: HDG Carbon Steel | Bronzphite®
Testing: Visual & Dimensional Tests

Piping Technology & Products, Inc. manufactured Bronzphite® slide plate assemblies for an oil refinery in Canada. The Bronzphite® is used as the lower slide plate bearing surface and measures 1/2″ x 4″ x 4″, and the carbon steel backing plates are 1/2″ x 7-1/2″ x 7-1/2″. The upper slide plate material is polished stainless steel. Bronzphite consists of a bronze plate that utilizes graphite inserts. Bronze is used because of its hardness and load-carrying abilities. The graphite “crumbles” when the load or weight of the equipment is placed on top of the slide plate assembly. This produces a thin film of graphite which acts as an oil-free lubricant between the lower bronze slide plate and upper stainless steel slide plate. The graphite greatly reduces friction between the two surfaces. The assembly is designed for an operating temperature of up to 1100°F, with an operating load of up to 5,000 PSI. Standard visual and dimensional tests were performed prior to a two-week delivery.

Piping Technology & Products and its subsidiaries are poised and ready to meet your project needs in their entirety. We design and build slide plates and an extensive range of additional products. We offer the largest and most comprehensive offering of products and services globally with US-based manufacturing for all your piping system considerations. Our foundation is based in oil, gas, power, and petrochemical; however, we work with mining, automotive, life sciences, data center, semiconductors, packaging, wood processing, and lumber plants serving over 50% of the S&P 100. We have been able to consistently match customer need dates to our production capabilities by utilizing our local engineering and manufacturing teams and our 24/7 2-shift operations and leveraging our 47-year history of experience and industry know-how.
