Teadit 24Sh Ring Gasket

Teadit 24Sh Ring Gasket
Manufacturers:
Ring gaskets are a flat sealing element, consisting of an inner and outer diameter sized to fit a flange's bore and bolt circle. Ring gaskets sit inside the flange's bolt circle. ASME B16.21 and ASME B16.47 govern the dimensions of ring gaskets for standard and large diameter pipe flanges. TEADIT 24SH is a large gasket sheet produced from 100% pure, multi-directionally expanded PTFE. Universally employable gasket sheet for all applications. It is suitable for all types of flanges, nearly all media, a wide temperature range and for applications with the toughest demands on purity. It is inherently clean and non-toxic. Gaskets of multi-directionally expanded PTFE have exceptional mechanical strength which allows operation with minimal creep at elevated temperatures. The excellent malleability of TEADIT 24SH makes repairing small damage and/or irregularities of the sealing area (flange surface) unnecessary. Gaskets cut from TEADIT 24SH are dimensionally stable, i. e. they do not get wider when compressed. This allows narrow flange faces to be sealed safely. TEADIT 24SH is quick and simple to install. The used gasket can be removed easily and without residue.

Governing Standards
| ASME B16.21 | Covers types, sizes, materials, dimensions, tolerances, and markings for nonmetallic flat gaskets. |
| ASME B16.47 | Covers pressure-temperature ratings, materials, dimensions, tolerances, marking, and testing for pipe flanges in sizes NPS 26 through NPS 60. Included are flanges with rating class designations 75, 150, 300, 400, 600, and 900 with requirements given in both SI (Metric) and U. S. Customary units, with diameter of bolts and flange bolt hole expressed in inch units. |
