Importance of Jacket Cleaning to Reactor Longevity

The August newsletter introduced information related to the importance of jacket cleaning to reactor longevity. Since August we had the opportunity to replace the lower sealer ring on a glass lined reactor that had been in service since 1991. This vessel is in service with approximately 25 additional reactors installed at the same time or earlier. […]

Demand for Glasslined Steel lifted by resurgence of Chemical and Pharma production in USA

This article focuses on the resurgence of three industries; Chemical, Pharma and Nuclear. Thirty-five years ago, these industries were booming in the USA, providing high paying jobs for skilled trades and professionals. Twenty years ago, there began a mass exodus of Chemical and Pharma plants leading to the term offshoring. Today, both are coming back […]

Prevent Downtime Caused by Gasket Failure

Product will pass through damaged gasket and erode the flange

Downtime in a chemical processing plant has been estimated to cost $500,000 per day or more, so discovering the root cause prior to gasket failure is worthwhile. Increasingly, the potential for failure may be diminished by giving these high consequence devices some attention. This photo exposes a classic example of damage caused by gasket failure. Once the […]

Tantalum Repair to Glass Lined Reactor at Agricultural Chemicals Plant

Large Tantalum patch across multiple axis'

This vessel is used in the production of agricultural chemicals. Due to market conditions the vendor supplies off-spec AHCL that contains trace amounts of fluorides in the 15-20ppm range.    The low Ph chemistry of the materials eroded a hole through the carbon steel sidewall at which time HCL was injected into the carbon steel […]

Glass Lined Vessel Inspection Procedure

Inspecting a Pfaudler Reactor

A good preventative maintenance program will include scheduled inspections An accurate estimate of the vessel service life can be made as glass thickness is recorded. Failure analysis is more easily performed as wear patterns are discovered early. Repairs are generally smaller and less expensive when detected early on Installed vessels should be inspected every 6-12 […]

Tantalum Repair to Glass Lined Flange

Flange repair with Tantalum patch

Flanges on glass lined equipment are vulnerable to failure. This begins the downward cycle toward eventual replacement of the equipment often sooner rather than later. Failure at the flange is among the most frequent cause for equipment replacement or re-glass  leading to costly equipment repairs, downtime, and replacement. There are two primary causes of flange damage. Sharing this information […]
