An LNG plant in Qatar experienced internal corrosion on a line carrying hydrocarbons with a high concentration of benzene, toluene, ethylbenzene, and xylene (BTEX). In total, a length of 7.5 m (24.6 feet) on an elevated 813-mm (32-inch) diameter line required repairs.

UKSummaryA 50.8-mm (2-inch) transformer cooling line in a nuclear plant had ruptured, and there was no way to isolate the line, which was leaking 3.75 liters (1 gallon) of transformer oil every hour. With the unit’s two other transformers offline for maintenance, it was critical to address the leaking line quickly without interrupting operations. CSNRI […]

North SeaSummaryThe seas around the UK and its islands are rich in energy resources, with diverse geology and geography. The sea also supports more than 230 varieties of fish, dolphins and whales. Environmental sensitivity is an essential element of operation for the many pipeline owners and operators in the area. Harsh weather, microbiologically influenced corrosion […]

Two carbon steel pipes were damaged with explosives interrupting crude transportation, the sale of which contributes much-needed revenue in the region. CSNRI was asked to assist with repairs on a small, unmanned platform off the West African coast. A solution incorporating ThermoWrap® MT was determined to be the best option for the repair.

Severe corrosion was identified in six vent stacks at the U bolt support and below the flame arrestor flanged connection. CSNRI was asked to provide an option for a permanent repair that could be completed without hot work or interruption of operation. ThermoWrap® MT was recommended to repair structural integrity of the vent stacks and extend service life, ensuring the plant would be operational past the intended decommissioning date.

In the northern UK, an independent British energy producer experienced failed flange welds on an 18” fire main, resulting in a leak. A solution was required that would arrest the live leak, prevent further leaks, and reinstate the strength and structural integrity of both defected flange sets. CSNRI engineers recommended a 10-layer application of ThermoWrap MT to restore the line to its original design capacity and extend its service life.
