Flange protectors prevent hazardous pipe corrosion

Protecting pipelines from the damaging effects of corrosion is an essential requirement for many offshore or onshore oil and gas installations, where if left unchecked can cause leakage, failure and in extreme cases, result in expensive shutdown.

US-based Allison Engineering have introduced its Kleerband flange protector brand as a solution to the problem of pipeline corrosion.

Allison believes its product offers clear benefits compared to traditional corrosion protection devices, such as shrink sleeves, tapes and wax fillers, and that they are easy to install.

‘The protectors feature a positive loading relief valve vent and plug which ensures complete loading of flange cavities, while a transparent and flexible polyband allows for 360º uninterrupted inspection, without the need to remove the protector,’ reads an Allison statement.

‘Kleerband protectors are also designed to fit all DIN and ANSI flanges from ½” diameter up to 144” and are also available for non-standard sizes and Christmas-Tree applications off-shore.’ 

In addition to being used on oil and gas installations the product can also be used for protecting flange faces, studs, gaskets and ring joints on pipelines in chemical plants, refineries, oil fields, metering stations, water and waste water plants, pump stations and underground pipelines.
