Pt&Amp;P Roller Hangers For An Aviation Facility In California

Type: Roller Hangers
Size: 12″ Wide and 15″ Tall
Material: Cast Iron & Carbon Steel
Design: 965 lbs. Operating Load & 10″ Pipe Size
Testing: Standard Quality Control

These Fig. 195 roller hangers were designed by PT&P for an aviation facility in California. They measure 12″ in width and 15″ in height. The rollers are fabricated from cast iron, with the yoke, roll rod, and hex nuts from carbon steel. The units are designed for a pipe size of 10″ and an operating load of 965 lbs. Standard quality control tests were performed prior to shipment. Roller hangers are used for the suspension of pipe from a single rod where axial movement may occur because of expansion or contraction. These are often used on bridges where pipelines cross waterways such as rivers and bayous. If there is extensive traffic, they can be used in conjunction with variable springs to accommodate such factors as vibration, wind, and other external factors. This particular job is an excellent demonstration of our ability to support quick turn request to meet the needs of our clients as it was shipped before the contract date in less than a week’s time.

Our roots are deeply embedded in the petrochemical, power, energy, and refining sectors. We remain adaptable, constantly seeking opportunities to contribute to pivotal projects. Our recent diversification into various industry verticals encompasses participation in both private and public sector space exploration. Additionally, we play a pivotal role in the flourishing 11.2 billion-dollar data center industry, driven by advancements in AI and its widespread adoption.

Time-to-market is a paramount consideration for our projects. Leveraging our Houston-based manufacturing facility, we stand out as a market leader, possessing the capability to support large volumes within tight timeframes. This agility is particularly crucial for the time-sensitive nature of semiconductor, pharmaceutical, EV battery, and automotive production facilities.

F-Type Variable Spring Supports with Graphite Slide Plates

December 19, 2023

F-Type Variable Spring Supports With Graphite Slide Plates Designed For An Oil Refinery

Type: Variable Spring Supports with Graphite Slide Plates
Materials: CS | HDG | High Heat Aluminum Finish | Graphite
Load Range: 420 lb. to 7650 lb. | 0.65″ Upward Movement
Design: 700°F Temperature | Q.C. & Load Tests

PT&P custom designed an F-type variable spring supports with graphite slide plates for an oil refinery in California. Client inspection O.C. inspections and load tests were conducted prior to shipment.

The graphite slide plates are used to accommodate the axial and lateral movement of the pipeline. Each assembly is equipped with specially designed “round” base plates (instead of the standard square plates) and is designed for temperatures up to 700°F. The spring cans are designed for a load range from 420 lb. to 7,650 lb. and movements up to 0.65″. In this case, they are finished with high-heat aluminum instead of our standard hot-dipped galvanized finish due to the high-temperature requirements in which these units will be operating. We have the unique capability to work with different materials based on the design needs. Variable spring supports, along with our array of engineered support solutions, stand as a fundamental pillar of our business. They enable us to actively collaborate with our clients, whether it involves the products we’ve manufactured, systems subjected to pipe stress and Finite Element Analysis (FEA), or items serviced through the expertise of our field service team.

For many of our products, we have the ability to build and deliver support in less than 24 hours should an emergency arise. It is useful to keep our emergency information handy on your phone and computers should an unforeseen moment arise. Please share this with your maintenance, fixed equipment, and reliability teams.

Big Ton Spring Supports Designed for a 98,250 lb. Load

December 5, 2023

Big Ton Spring Supports Designed For A 98,250 Lb. Load

Type: Big Ton Spring Supports
Size: 29″ wide x 110″ long x 35″ high
Material: HDG Carbon Steel | A193 Gr. B7 Travel Stops and Load Column
Design: 98,250 lb. | 1-3/4″ Upward
Testing: Load Cell Test

This big ton spring support assembly was designed for a facility in Kansas. For this application PTP’s big ton was used to support heat transfer and steam generating equipment typically used in fossil fuel power generation, combined cycle power generation, petrochemical, and process industries.

Big Ton spring supports are extremely stable. Base supports springs of this design are frequently used under horizontal pressure vessel saddle supports in combination with slide plates or roller supports. Our Big Ton design lends itself ideally to this support situation. Type F design is sufficient where there is a minimal amount of lateral movement, but where the combination of heavy loads and thermal expansion are required, Big Ton industrial springs should be your choice.

The big ton assemblies were fabricated from hot-dipped galvanized carbon steel and include neoprene coated springs coils. The travel stops and load column material is A193 Gr. B7. The units measure 29″ wide x 110″ long x 35″ high and are capable of supporting loads up to 98,250 lb. while accommodating movements from 1-3/4″ upward. The big tons were tested at our facility with a load cell designed by our team to ensure proper operation throughout the big ton’s operating range.

Alongside our ability to design and manufacture big tons specific to your system needs, our field service team is readily available to service, audit, maintain, and/or assist with installation of such products. For more on installation and maintenance take a look at our resource page:
