|---|---|
| Material | EPDM |
| Pipe dimension (ND) | 15 |
Features
High operational safety Low tightening torques Dimensional stability Large operating temperature rangeAreas of application
Sealing and isolation of flange connections in corrosion protection plants, for electrical separation. Flange Isolation for cathodic corrosion protection of flange sealing surfaces in combination with isolation sleeves and isolation washers. Flange Isolation to meet the requirements of technical regulations for flammable gases and liquids. The flange gaskets GLV-UniSeal® T and GGr can, of course, also be used as gaskets without Isolation.Description
Easy and quick installation. Can be mounted with " standard tools" and torque wrench.Assembly Instructions
| 1 | If only the smaller collar is used, the larger one can be cut, if necessary. |
| 2 | The gasket must not be damaged. |
| 3 | Greasy separating agents or lubricants should not come into contact with the rubber gasket. |
| 5 | Tighten the bolts evenly several times in a crosswise sequence. |
| 6 | Ensure that bolts are well lubricated . |
| 7 | Always use torque wrench to ensure even tightening. |
| 8 | Appropriate pipe support must be in place in order to prevent the pipe from settling, otherwise the gasket will be squeezed on one side. |
| 9 | Rubber/steel gaskets should not be used more than once. |
| ! | For flanges ND 15 - ND 600: The values are based on a coefficient of friction of µ = 0.12 and a maximum surface pressure of 15 N/mm2 . The number and sizes of bolts comply with DIN standards 2632 to 2635. The guide values for tightening torques for flanges larger than ND 600 can be calculated according to the following rule of thumb:
PN 10: ND / 3 = torque in Nm PN 16: ND / 1.5 = torque in Nm PN 25: ND = torque in Nm PN 40: ND * 2 = torque in Nm
If the flange material consists of plastic, e.g. PE, please note that the tightening torques must be adjusted or reduced according to the respective flange material |
