Custom Big Ton Springs Designed For A 122,000 Lb. Load For A Chemical Plant

Type: Big Ton Spring Supports
Size: 52-3/4″ L x 38-3/4″ W x 91″ H
Design: 121,916 lb. Load | 3/4″ Upwards Movement
Material: HDG Carbon Steel | Neoprene Coated Springs
Testing: Load Calibration Test | Hydro-tested

PT&P custom designed a big ton spring support for a chemical plant in Pennsylvania. The big ton will be used to support a vessel in excess of 121,916 lb. and a movement of 3/4” upwards. The dimensions for this unit are 52-3/4” L x 38-3/4” W x 91” H. The big ton spring support is designed to support large and heavy units such as compressors, vessels, and pumps in power and petrochemical plants. They are designed to allow limited movement in confined areas. By doing this, it saves the customer from having to entirely redesign the piping system and saves thousands of dollars. The big ton has an internal guide and special pedestal which was designed to meet the required height of the spring and withstand the hydro-test load. A load calibration test was performed before shipping.

Custom Designed Big Ton Spring Supports For A Propane Dehydrogenation Application In Texas

Type: Big Ton Spring Supports
Size: 42″ x 24″ x 26 1/2″
Material: Carbon Steel
Design: 94,261 lb. Load & 0.085” Movement
Testing: Standard Load Tests

PT&P custom designed big ton spring supports for a propane dehydrogenation application at a chemical plant in Texas. The components within this assembly include the spring housing, coils, name plates, pressure plate, and load indicator. While both assemblies measure 42” L x 24” W x 26-1/2” H, it was modified based on independent specifications for operating loads and movement to accommodate a load of 94,261 lb. and 0.085” of movement. This type of support is ideal for applications, such as supporting pressure vessels that combine very heavy loads with thermal expansion because of the stability they provide. The big ton was tested in the load cell to insure proper operation throughout the entire working range of the coils.
