Door Joints and Gasket materials
Choice of Door Joint materials. We stock ready made door joints in three types of material. They are: 1) Graphited Prekev We now also stock Tefcan universal joint sealing, supplied on a coil. A brief description of their properties is given below: |
|||
 |
Graphited Prekev: Manufactured from Keramab Prekev rubberized cloth with stainless steel insert. Properties: Resistant to water, steam and aqueous solutions from pH3 to pH13. Manufacturers stated max temperature: 250°C Manufacturers stated max pressure: 35 bar (500psi) |
||
 |
Blue Max: When used on steam pressure vessels, Blue Max is suitable for use up to 31 bar (450psi). Installation involves a mandatory curing time, during which expansion of the joint occurs. This makes the material particularly suited to rough and pitted surfaces. (See installation instructions) |

 |
Topog-E: Topog-E Gaskets are sometimes used at pressures above 200 psi (14 bar), but their useful life is reduced under these severe conditions. When used in other applications (e.g. condensate, water, and air vessels) where operating conditions are less severe, (e.g. below 250°F./121°C), Topog-E Gaskets can provide very long service lives. |
