Packing series

Product details

The packing is made of white asbestos fiber cords impregnated with PTFE dispersion. (Addition of lubricant is operational. ) It is soft in texture and suitable as the sealing of pumps for liquidated chemicals. However, packing impregnated with lubricants is recommended for use with reciprocating pumps or for the sealing in places where linear velocity is up to 10m/s.

Product details

Pre-impregnated, twisted cotton yarn, intensively re-impregnated during braided, an economical packing for stated limits of application.

The colorless impregnation prevents any discoloration of the product. The packing is therefore mainly used with clean media.

Due to its sea water resistant impregnation, the packing can be also be used for sealing stern tubes and rudder posts.

It can be used in water, sewage water, sea water, salt solution.

Product details

In order to manufacture different kinds of reinforced flexible graphite yarns to be used for making different kinds flexible graphite packing, we use flexible graphite as basic material, mixing with natural fiber, metal alloy wire (respectively) and proper binding agent, then through specially designed technological process. The packing made of these flexible yarns reinforced by different media, circumstance, temperature and pressure. Furthermore, for using these products under severely corrosion can be added into the graphite yarns for making the properties of the graphite sealing parts more perfect.

Product details

The pasting braided by technology of braiding around a core (or cores) or multiple sieve braid, etc. with our flexible graphite yarn, have the perfect safe properties on sealing. They are the best composite parts for solving sealing problem. In addition, according to conditions of different corrosive circumstances and customer's demands, the packing can be treated with inhibitions of corrosion to make their anticorrosive property better. These products are almost suitable to all media, such as hot water steam, oil, heat-exchanging liquids, acids, alkalis, ammonia, hydrogen, organic solvents, hydrocarbons, low temperature liquids, etc.

They can be applied to the equipments and devices in petroleum, electricity generation, chemical pharmaceutical and light industries.

Product details

PTFE fiber packing is a pure yarn packing braided into square cross section and impregnated with PTFE dispersion. High cross-sectional density and structural strength. Inert to almost all chemicals and has great resistance to mechanical attack. Low coefficient of friction results in easy shaft running. Long service duration is ensured as PTFE yarns are stable and there is no lubricant squeezed out under operating pressure.
