GFI Composites Ltd. was asked to design and supply light weight drifts of various diameters to offshore Oil and Gas customers.
These drifts have to meet existing criteria including meeting tolerances of +/- 0.001″. In addition, they have to be light weight; chemical and corrosion resistance; excellent abrasion resistance which will not shrink or swell in any weather condition; and possess good impact strength.
GFI Composites Ltd. developed an aluminum drift casing made from 6061 aluminum. This is an alternate material used when weight is an issue. Mostly used for the larger diameter casing drift.
