CONNECTING PEXGOL PIPES WITH FLARED ENDS
The flared-end connection is suitable for both hot and cold media. Special Fixpoint clamps should be used before and after the flared ends. Flange material is carbon steel A37. Other carbon steel or stainless steel grades can be ordered.
In case of subzero temperatures, special restraining techniques should be employed to prevent pulling out of the flared end from the flanges.
No gasket is needed when connecting two Pexgol pipes with flared ends and flanges or when connecting a Pexgol pipe with a flared end to a flanged fitting.
Tighten the bolts evenly around the flange until all the bolts are all tight.
If torque wrenches are applied, use the recommended values in the following table. Tighten the bolts evenly using 75% of the recommended torque values and then tighten to the final value.
No retorquing is necessary in the flared ends of Pexgol pipes!
