A petroleum refinery was having difficulty removing threaded assemblies from reactors, cracking units and flanged connections following two years in service. Several penetrating oils were tried but none proved effective, and torch cutting was dangerous and required permits. Chesterton offered the perfect alternative in the Chesterton 723™ Sprasolvo®, which penetrated the nuts and bolts in minutes and allowed for a more efficient removal process. This lubricant has been added to the stock supply system and is now standardised at the refinery.

Challenge

Goal

Find new solution for removing threaded assemblies.

Background

A petroleum refinery was having difficulty removing threaded assemblies from reactors, cracking units and flanged connections following two years in service. Several penetrating oils were tried but none proved effective, and torch cutting was dangerous and required permits.

Downtime and loss of production was a critical concern for the customer.

Solution

A small amount of Chesterton 723™ Sprasolvo® was applied and allowed to penetrate the nuts and bolts for ten minutes. All of the bolts were then removed easily.

The customer found this solution quicker, safer, and more cost-effective than cutting the bolts.

Previously, 3 men with hot work permits were required for 6 hours to disassemble flange bolts.

Results

Chesterton 723 Sprasolvo® out performed all of the competitive products and has eliminated the need for torch cutting.

This lubricant has been added to the stock supply system and is now standardized at the refinery.

Two men easily remove flange bolts in 2 hours with Chesterton 723 Sprasolvo®.
