asbestos packing of APR
The packing of APR is an elastic rope of square or round section, interlaced from an asbestine tape with a brass wire by a diameter 0,17-0,2 mm, impregnated with antifrikcionnym by fatty composition on the basis of oil extracts, graphitized GOST 5152-84. Size of section: 4-30 mm.Produced in coils or bobbins, bandaged by string by a middle-weight 18-22 kg. Coils are packed in paper or polyethylene sack, bag-grade paper, or polyethylene tape.
Used in the stuffing-box compressions of armature, working with neutral, liquid, aggressive environments at pressure not higher 32 Mpa and temperature from — 70 to + 200 °С, and also with petroleum at pressure not higher 2 Mpa and temperature from — 30 to + 300 °С.
Used in the stuffing-box compressions of chempumps, workings with liquid, neutral and aggressive environments and with petroleum at pressure not higher 2,5 Mpa and temperature not higher + 210 °С., and sliding speeds a to 15 m/s.
Used in piston pumps, workings with liquid, neutral and aggressive environments and petroleum at pressure to 4,5 Mpa and temperature not higher + 210 °С, possible speed of sliding is a 2 m/s . Guarantee term of storage — 5 years from the day of making. Terms of storage: closed storage facilities, to protect from direct sunbeams, hold farther than a 1 m from heat-radiating devices.
