Constant Spring Supports Custom-Designed for One of the Largest Crude Oil Processing Facilities in the World

Piping Technology & Products custom-designed constant spring supports for crude oil processing at one of the largest refineries in the world. Petroleum refineries change crude oil into products such as jet fuel, gasoline, polypropylene, polyethylene, propane, sulphur, carbon black feed, and diesel that can be used for transportation, heating, feedstocks for making other chemicals, generating electricity, renewable energy, and paving roads. Piping Technology and Products was awarded this project because we were the only engineering manufacturing firm vendor of constant spring manufacturers in the world that could both design, manufacture, and test these units for the unique design conditions. These constant springs will support loads ranging from 88,185 lb. to 143,300 lb. They are designed for temperatures up to 650°F, and movements of 0.39” up, 4.72” down, -2.36” up, and 0.39” down. The Type-C constants are 67” H x 21” W x 88.25” L and the Type-F constants are 85” H X 39.75” W x 86.56” L. The F-Type springs will include graphite slide plates and are designed to support the piping from below while allowing both lateral and axial movement. All constant assemblies underwent magnetic particle inspection of welds, travel, and compression tests. Additionally, a special “cramp test” was conducted on each spring coil. A “cramp test” is done by compressing the spring coil by a specified length for a specific period of time. This assures the spring’s functionally especially when a large “wire diameter” is used to manufacture the spring coil for these high loads. At Piping Technology and Products and our subsidiaries, we specialize in designing pipe supports, expansion joints, and insulated supports for unique applications involving products not readily available. Our products are used in the CDU (crude distillation units), hydrocracking units, RFCC (residual fluid catalytic cracking), naphtha hydrotreater, and hydrodesulfurization units (also known as alkylation unit), and sulphuric acid regeneration (SAR) units in refineries.

Compact Springs for a Chemical Manufacturing Plant in Agricultural

Compact Spring Supports Custom-Designed for a Chemical Manufacturing Plant in Agricultural

Compact spring supports (also known as disc springs) were custom-designed for a chemical plant in the agricultural industry. We design each compact spring for specific applications. Usually, they are used in “tight” spaces where the conventional variable spring is too tall to fit the allowable space between the pipeline and supporting steel structures. In general, compact springs serve the same function as a conventional variable spring, to relieve vibration and stress in the pipeline and associated equipment. The springs supplied here are designed for loads ranging from 5,038 lb. to 15,144 lb. and spring rates from 5,904 lb./in. to 44,455 lb./in. Also, these disc springs were designed for thermal movement ranging from 0.011” to 0.46”. The assemblies are fabricated from 304 stainless steel and include Bronzphite® and stainless steel slide plates to lower the coefficient of friction due to lateral movement. Since there is lateral movement, the conventional variable spring would require “internally guided load columns”, however, these units incorporate a “guiding” feature within the spring’s design. They have an installed height of 10-1/2″ – 26”. Each assembly underwent load testing and other NDE and visual inspection by our QC department before shipment. Applications such as Skid Mounted Process Equipment, Pump and Control Skids, Skid Plants, and other types of Skid Packages where space is extremely limited are ideal applications for Compact Springs.
