摘要： Use of a sealing material which is a multifilament or spun yarn coated with a joint sealing composition to seal a joint in a pipe system in which system a fluid having corrosion inhibitors such as diammonium dimolybdate or benzotriazole; and/or sludge removers; and/or an alcohol such as propane diol, or ethylene glycol; and/or a hydrocarbon such as diesel, including biodiesel, fuel oil, or hydraulic oil; and/or steam at a temperature of at least 180° C. and a pressure of at least 10 bar (1000 kPa); is to be passed through the sealed joint. It is surprising that the sealing materials of the invention can maintain a sealed joint despite exposure to such materials.

摘要： A sealant material for sealing threaded pipe joints that is a multifilament or spun polyphenylene sulfide yarn and a joint sealing composition comprising a silicone oil or a natural oil with a smoke point of about 230° C. or higher. The polyphenylene sulfide yarn is coated with the joint sealant composition. The material forms an effective seal and is resistant even when used in systems in which it is exposed to temperatures in excess of 280° C. The material may be provided in a dispenser.
