Straight version Duofit D10 for repairs on damaged pipes (cracks, faulty weldings, corrosion, etc.) with no service cut off on pipes of any diameter.
It can be also used for hot tapping techniques on pipes of any material and diameter with running fluids.
Carbon steel central body conveniently built in order to allow a perfect insertion of the gasket inside its dedicated conical seat.
Carbon steel compression followers which allow compression of the gasket onto the pipe surface upon tightening the bolts.
Truncated-cone sealing gasket which can be perfectly inserted between the central body of the coupling and the circumference of the pipe. It allows a complete hydraulic seal and a 30 mm tolerance range on the pipe OD.
Round or square holes for the bolt insertion.
The compression bolts allow the approaching of the compression flanges and the consequent compression of the gasket onto the pipe.
Manufactured in carbon steel, designed according to the length and the diameter of the pipe or of the sleeve to be repaired, in order to perfectly cover them.
Manufactured in carbon steel, they allow the union of the two longitudinal shells of the DUOFIT allowing the repairing of the leak.
Lateral gasket with square section, it is compressed between the lateral plates and allows the hydraulic seal along the entire length of the Duofit.
