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.

Big Ton Spring Supports Designed for an Oil Refinery in Australia

Type: Big Ton Spring Supports
Material: A36 carbon steel | Hot-dipped Galvanized | SS Slide Plates
Design: 16,276 lb. Ld. | 0.196″ Up Travel

The big ton spring support is used for supporting large heavy units such as compressors, vessels and pumps in power and petrochemical plants. The housing and frame are fabricated from carbon steel and the spring coils are coated in neoprene. Polished stainless steel slide plates are added to the top of the load flange, which reduces the coefficient of friction to allow for lateral movement. This big ton spring support is designed to allow limited movement of 0.196″ upwards, with an operating load of 16,276 lb. This big ton spring enabled the client to reduce engineering man hours by avoiding the redesign of the piping system due to limited space requirement.

C-Type Constant Springs Designed for a Chemical Plant in Italy

Type: Constant Spring Supports
Size: 14″ x 19″ x 64″
Material: A36 Carbon Steel
Design: 2 1/2” to 5” Total Travel and 7,681 lb. Load
Testing: Standard Load and Travel Tests

PT&P custom designed and manufactured C-Type constant spring supports for a chemical plant in Italy.
