    Graphite Paking

    Graphite Packing


    LOADING IMAGES

    Packing sealing is a type of gland seal,making a stuffing box on the system body.The stuffing box is

    filled with good compression and elasticity fillers,clamped one end with the gland,resulting in radialpressure to achieve seal.It is usually applied in the occasion with two parts with relative movement,such asvalve,pump and stuffing box type heating exchanger.There are various forms of filler structure.The maintype is Braided Filler.

    Packing can be classified into twisted type,eight-knitting type,jacketed braided type and feedthrough

    weaving type by the structure.Furthermore,it is classified into Graphite Packing,Mineral Fibre Packing andSynthetic Fibre Packing by the structure materials.Feedthrough weaving type is the main packing style.Inour catalogue,we classify them in the form of structure materials based on feedthrough weaving type.Butwe can provide other types of weaving for especial requirements.

    AT305L1 Graphite Packingwith carbon fibre cornerdiagonally weaved fromexpanded graphite,improvinganti-extrusion capacity andcompressive strength.
    AT305L2 Graphite Packing
    cross-weaved up with carbon
    fibre and expanded graphite.
    It can be used in both dynamic
    and static seals,particularly
    suited in high temperature and
    pressure pump and valve.
