Flange Insulation Kits Sealing and Gaskets

Flange Insulation Kits - sealing selections for applications where cathodic corrosion is a concern

Corrosion has long been natures most destructive element, but with LoneStar flange insulation products this costly profit robbing item can all but be eliminated. LoneStar engineered insulation products, of consistent high quality, can be used to control and confine electrolytic corrosion in almost every piping system. LoneStar insulation products are manufactured from materials with superior high dielectric strength, low water absorption and chemical stability to maintain the high quality required in refinery and chemical plant applications. Hydrocarbon exposure, weathering and salt water are no problem for LoneStar insulating materials. LoneStar quality assurance and high production rate allow our customers to economically protect and lengthen the service life of equipment with little or no down time due to electrolysis. 
LoneStar manufactures a full line of standard flange insulation sets including Type F (Ring) gaskets, Type E (Full Face) gaskets and Type D (API Ring Joint) gaskets. LoneStar Type F and E gaskets are manufactured from 1/8" thick fabric based phenolic (Nema Grade CE) sheet with either no coating (plain faced) or a Nitrile rubber coating on both faces. Type F & E gaskets are also available in Compressed Non-Asbestos with superior electrical insulation qualities.

Insulation Kits

Flange insulating sets are packaged for one flanged joint, including gasket, sleeves and washers. Each flange set is securely packaged in a cardboard box, clearly labelled as to size, ASA Rating, style and material. Either polyethylene or phenolic sleeves are available with these insulating sets. Polyethylene sleeves are standard and will be furnished unless otherwise specified.
