New goods. New services. PolyOil, Ltd. http://1420.uk.all.biz Sun, 26 Feb 2012 07:22:53 +0200 http://www.all.biz/img/logo.gif http://1420.uk.all.biz http://www.uk.all.biz/g851/ Our hinged centralisers have been designed with the usual outstanding benefit of reduced friction, torque and drag, whilst allowing fast mid joint fitting and retrofitting. Certain screen placements have a requirement for a hinge feature – such as centralisation between two screen jackets in the middle of a joint or below the coupling for instance. These centralisers can be supplied with straight blades for gravel packing or helical blades for cementing operations.]]> Thu, 03 May 2007 00:00:00 +0300 http://www.uk.all.biz/g851/
