Gaskets

Gaskets isolate one section of a pipeline from another, protecting them from cathodic corrosion caused when two pieces of metal contact each other. For high- and low-temperature applications, a disk of Norplex-Micarta composite material is placed between the two flanges of connecting pipeline sections, separating the metal when sections are bolted together. During installation for pipeline applications, gaskets, tubes, and washers must withstand compressive forces as high as 2,000 to 5,000 psias the secti.
