PT&P custom-designed U-type constant spring supports for an oil refinery in Texas. Constants can be utilized in refineries within blocks such as hydrogenation units, naphtha desulfurization units, and fluid catalytic crackers. The spring’s frame is manufactured from A36 carbon steel and hot-dipped galvanized to protect against corrosion. For instances where there was axial and lateral movement, 240 Gr. 304 slide plates were installed on the load flanges of the constants. The constants supplied are designed for an operating load ranging from 1,085 lb. up to 17,480 lb. and horizontal travel from 2.5” to 6”. The overall dimensions range in size from 17” H x 20” W x 31” L to 28” H x 26” W x 66” L. Load and travel tests per industry standards were performed prior to shipment.

*Note: Time Zone is CDT * Central Daylight Savings Time / GMT -5h
Live Webinars are 1 PE/PDH Credit for TX Professional Engineers
Learn how the theoretical applications of spring supports are put into use in the real world. We will start with a review of the working principles of both variable and constant springs. See how brand new spring looks at delivery, and review installation guidelines. Learn the key points to review through the total installation process and subsequently when the springs are in operation. See how to determine if springs need adjustments, re-calibration, refurbishment, or replacement. View in field examples, shutdown, and isolation procedures. See the selection process required when there are significant changes to the operating condition.
