Piping Technology and Products, Inc. designed and manufactured 240 PT&P Figure 110 welded eye rods for an ammonia plant in Saudi Arabia. The rods will be attached to Type A variable springs designed to support loads from 850 lb. to 13,300 lb. Manufactured from A-36 carbon steel, the rods are 3/4 to 2 in diameter and range in length from 68 to 95. To prevent contamination at high temperatures, a red oxide primer with an alkyd topcoat was applied to the rods as per the customer’s request. Prior to shipment, a 100% dye-penetrant test was performed to ensure quality.
The rod and clevis components were made of various alloys (800H, F91, 316H, SA-387 Gr. 22) and ranged in sizes from 2″ to 4″ diameter. Taking into account the surrounding environment’s conditions, engineers designed the rods and clevises so that they can endure temperatures escalating to 1430º F. For the duration of a pull test conducted, the clevises and rods sustained loads up to 152,000 lbs. and there were no discrepancies.
Piping Technology & Products, Inc. custom designed and fabricated 1,728 rods and clevises for a heat recovery steam generation plant. The rods and clevises will be utilized to support various pipe loads throughout the piping system.
