Liquid mesh filters for pipelines

TU3616-004-00220339-97 (OKP 36 1600) Liquid mesh filters for pipelines for conditional pressures of 1.6 and 4.0 MPa at the temperature of the transported fluid from minus 60 to 300 ° C, are designed to protect pumping and other equipment from process impurities in the oil refining, petrochemical, oil and gas industries . The sizes of entrained solid particles of mechanical impurities are more than 200 microns. Hazard classes of the transported fluid 1, 2, 3 and 4 GOST 12.1.007-76. Two filter designs are made according to the method of connection with the pipeline: * execution 1 - on flanges; * execution 2 - by welding. Depending on the temperature of the transported fluid, the filters are manufactured in four material versions: * steel 16GS (from minus 30 ° С to 300 ° С); * steel 09G2S-8 (from minus 60 ° С to 300 ° С); * steel 08Х22Н6Т (from minus 40 ° С to 300 ° С); * steel 09G2S-7 (from minus 46 ° С to 300 ° С). Upon customer request, filters can be manufactured with heat treatment. The service life is 20 years, during the operation of filters with environments that cause the penetration rate of corrosion into the depth of the metal to no more than 0.1 mm per year, 12 years at a corrosion penetration rate of up to 0.17 mm per year.
