Describe:

Type PTFE gasket is made of molded PTFE skiving sheet or sheet according to the standards of ANSI, DIN or JIS non-standard at the request of customers. Material thickness from 0.25mm – 6mm. Circular coils from 150 – 1200 mm, or plate area from 75-300 square centimeters. The larger sizes can meet the requirements of customers with the smallest tolerances.

PTFE material is a soft, low friction coefficient, insulation and chemical resistance superior, resistant to extreme weather conditions, stable operation in high temperature environments up to 230 ° C.

HOW TO CHOOSE Gasket – Gaskets – WASHER

Gaskets – gasket – Gaskets can be defined into three main categories , non-metallic , semi- metallic and metallic .

1 – Non-metallic linings (Non – Metallic) – non-metallic Gasket
Usually the plates are synthetic materials used for low-pressure applications , suitable for a wide range of corrosive chemicals in general . It includes : rubber pad – Ruber , asbestos does not cover plates – Compressed Asbestos Fiber ( CAF ) Sheets , Non – Asbestos Fiber Sheets , PTFE Sealing – PTFE gaskets , Insulating gaskets , pads graphite – Graphite Sheet Products.

2 – Semi- metallic linings (Semi – Metallic) – Metal Gasket sale :
Is a mixture washers including metallic and non-metallic , it suits applications with high pressure and temperature . It includes : Metal jacketed gaskets , metal washers – gaskets Spiral Wound .

3 – Linings of metal (Metallic ) – Metal Gasket
It is made from a metal or a combination of several kinds of metals , sizes and shapes depending on the temperature and pressure of the equipment . It includes : Ring Type Joints, Lens Rings , Delta Rings , Bridgeman Rings , gaskets Serrated , Corrugated gaskets .

The mechanical properties and performance of the pads will vary , depending on the type of buffer to be selected and the materials in which it is produced . Obviously , the mechanical properties is an important factor when considering gasket design , but the choice of a type of buffer affected by the following factors :

  • The temperature of the device that it leads through .
  • The pressure of the application.
  • Corrosive of applications .
