As Aspart of ofour continuing product development we now offer an extended range of Pipe Supports that have been particularly designed for the Oil, Gas and Process Industries. Our WITCHLINER range of ofproducts is istoto suit Stainless Steel, Duplex, Super Duplex and Cupro- Nickel Piping and incorporate moulded isolation/ encasing materials silicone materials thus:- for :- temp range -70 C to 300 CNeoprene (temp range -30 o C to 100 o C) This material Silicone offers (tempextensive range -70performance o C to 300 o C) qualities, and can be utilised in a wide range of pipework Both materials offer extensive performance qualities, installations. and can be utilised in a wide range of pipework installations. HT/FR Silicone Rubber Elastomer Chloroprene, Silicone rubber generally is a chemically known under inert synthetic Du Pont trade Silicone rubber is a chemically inert synthetic name elastomer of Neoprene, which differs is probably from other most synthetic commonly and elastomer which differs from other synthetic and used natural synthetic rubbers rubber. in that it is able to maintain excellent natural rubbers in that it is able to maintain excellent This elasticity material andisresilience strong, resilient, over a wide and achieves temperature an elasticity and resilience over a wide temperature extremely range.
