Big-Ton D and Big-Ton T Upthrust Constants

Big-Ton D and Big-Ton T Upthrust Constants

PT&P custom designed and built four Big Ton D Upthrust Constants(figure 1) and two pairs of Big Ton T Upthrust Constants (figure 2) for a global engineering & construction company.

These upthrust constants are installed at a Petrochemical Plant in Siberia. Due to space limitation, the Big Ton D Upthrust Constants and Big Ton T Upthrust Constants were designed for a total travel of 5″ and 4″ respectively. The Big Ton D Upthrust Constants were also designed for a load of 50,022 Ibs with a height of 26 inches. The Big Ton T Upthrust Constants with a height of 16.5″ were designed for 75,000 Ibs, and 67,464 Ibs respectively.

Emergency Field Service Request on Constant

Emergency Field Service Request on Constant

Emergency Field Service Request on Constant

Piping Technology & Products, Inc. and its 24×7 Quick Turn/Emergency Service were put to the test on a Friday evening when they received an emergency call from a company located in Jamaica. The Jamaican company was concerned with existing pipe supports at their location and made a request for a PT&P field services representative to visit and inspect.

An experienced PT&P field services manager arrived at 8:00 p.m. on Saturday to survey and fulfill the request.

The reported problem was a pair of rusted and decayed spring hangers dating back to 1969. After inspection, PT&P’s field services manager concluded that the aged spring hangers could no longer support the piping system due to changes in the design of the system, whereas, failure resulted in additional forces being exerted onto the steam turbine.

Following identification of the measurements, load capabilities, and movements of the spring hangers, it was apparent that the system design did not compensate for the weight of two globe valves that were added to the system at a later date. Thus, PT&P’s field services manager had to take into consideration the weight of these two globe valves when sizing the replacement parts.

PT&P supplied and delivered two Type G variable spring assemblies to Jamaica on the following Monday. Type G assemblies can accommodate unusually heavy loads, and is especially adaptable for avoiding interference in spaces where headroom is limited. In this case, the spring assembly was supporting loads in excess of 2000 lbs. and movement was limited due to its location in the powerhouse.

16’ Dia. x 20’ Carbon Steel Storage Tank

Dual cranes are required to lift the pictured 16’ x 20’ Carbon Steel Storage Tank to a flatbed eighteen-wheeler for transportation to the paint yard.Upon completion of painting and lining it will be shipped to a major producer of caustic soda in Corpus Christi, South Texas Area.

This is one of many (similar type) tanks and pressure vessels supplied for a recent plant expansion.
