Description

Mechanical Packing , PTFE braided packing , sealing packing Scope of application: It is applecable for all kinds of corrosive chemicals including strong corrosive liquids(such as liquid strong alkale, hydrochloric acid and sulfuric acid), organic solvent and liquid nitrogen, ***** is applicable to the industrial fields of petroleum, chemical industry, chemical fiber, coal cutting generating power and metallurgy, etc It especially adapts to the sealing for high pressure valve, plunger pump, stirrer and mixer, etc. Features: This packing has the characteristics of good corrosive resistance, wear resistance, high mechanisn strength, and good self lubricating, small friction coefficient and small torque, however its heat conductivity is bad and the thermal coefficient of expansion is big, so the measurs of forced cooling and lubrication must be adopred for sealing on positon with high linear velocity , co as to avoid burning packing and increasing wearing.
