Big Ton Constant Supports Designed with Bronzphite® Slide Plates for Oil Refinery in China

Type: Big Ton Constant Spring Supports
Material: Carbon Steel | HDG | Bronzphite® | Graphite
Design: 750°F | 1-1/2″ Total Travel | 29-1/2″ x 85-1/4″ x 34-1/2″ | 187,393 lb.
Testing: Load and Travel Testing

PT&P custom designed and manufactured big ton constant spring supports w/ bronzphite® slide plates for a 400 KTA light oil for a processing and utilization unit at an oil refinery in China. A total of four constant assemblies were fabricated from carbon steel and hot-dipped galvanized for extra protection against corrosion. The bronze plate acts as the bearing surface, supporting heavy loads, while the graphite inserts provide a solid, oil-free sliding surface. They are designed for operating temperatures up to 750°F and an operating load of 187,393 lb., with 1-1/2″ total travel. Load and travel testing was performed prior to shipment.

Cryogenic Pipe Supports Designed for a Facility in Massachusetts

Cryogenic Pipe Supports Designed for a Facility in Massachusetts

Type: Cryogenic Pipe Supports
Material: Carbon Steel | Polyurethane
Design: -320°F | 36″ – 48″ Dia. | 52″ W x 57″ H x 67″ L

PT&P received an order to custom design 16 cryogenic pipe supports for a contractor in Massachusetts. They needed a pipe forming a T-section lined with insulation and trimmed to accommodate the pipe perpendicular to the shoe length. The overall dimensions of the order are pipe sizes ranging from 36″ to 48″ in diameter, 52″ width and 57″ to 67″ height. Our insulation is designed to support the pipe and its contents. When insulated pipes are supported, the weight of the pipe, the contents, the operating temperature, and the amount of energy loss must be considered. In order to support the pipe and minimize energy loss from heat transfer, a pre-insulated pipe support is necessary. If the material in the pipe is high temperature such as high pressure steam or heating oil, then high temperature insulation is required, and these supports are called hot shoes. If the material is cold, such as liquefied natural gas, cooling water or ammonia, then low temperature insulation is needed, and these types of supports are called cold shoes.
