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.

| AT301 | Pure Graphite | 550 | 0-14 20m/s | 300（Valve） 20（Rotary pump） 50（Stirrer） | It has good wear resistance,canbe affixed to valve stem and shaftsurface easily,is well suitable insight temperature and pressuremedium,such as high-pressuresteam,heat medium,neutral gas,gas,hydrogen,ammonia, organic solvent and hydrocarbons. |
| AT302 | Graphite Packing with Inconel wire | 550 | 0-14 | 320（Valve） | It is made up of Inconel wirereinforced expanded graphite,suitable for sealing large gap,high temperature andpressure circumstance.Medium is the same as AT301. |
| AT304 | High Temperature and Pressure Graphite Packing with Inconel wire | 600 | 0-14 | 400（Valve） | It is a ring type with Inconelmesh clad.This product offersgood resistances at ultra-hightemperature and ultra-highpressure.Thus,it can be usedin steam valve and highpressure valve with hightemperature and pressurecircumstance. |
| AT305 | Graphite Carbon Fibre Packing | 550 | 0-14 12m/s | 300（Valve）100ba（Reciprocating） 25bar（Rotary pump） | 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. |
