Specifification selection and installation

The selection of the correct size of the sealing belt should take into account the following factors the composition and width of the sealing surface, the structure of bolts and flanges, and the specific working conditions.

Method

Clean and dry the seal face, choose a certain width of the bulk ptfe sealing tape, tear to protect paper, adhesive tape to seal the surface near the a bolt will be sealed with paste, exploring end in a near the bolt cross overlapping, intersection outside the more than 2 cm above (note: use on the plane of the flange, the two end must cross overlapping. When used on groove flanges, it can be overlapped in parallel with each other more than 2cm), close the corresponding sealing surface, tighten each bolt evenly, the cross part of the two ends will be pressed to the same thickness asv other parts, and the cross part will never leak.
