Cylinder Joint Couplings

All EECO facilities are currently open during normal business hours in order to serve our customers. If this situation changes, we will provide information here.

Cylinder Joint Couplings

EECO has four different means of Cylinder Joints available to fit any job site requirements.

Threaded No Weld Joint

The threaded no weld cylinder joint is available up to 10” cylinder diameters. This joint system is designed with a double O-ring that will protect the cylinder joint from internal and external leakage. Threaded no weld joint can be welded, filling the 1/2 inch gap between couplings, if the specifications require or at the discretion of the Installation Company.

Threaded Joint

The threaded cylinder joint is available 12” through 16” cylinder diameters. The female threaded coupling is welded to the upper side of the next joint. The cylinder opposite section is threaded to screw into coupling where it is then welded in the field.

Slip-Fit Joint

The slip-fit cylinder joint is available up to 16” cylinder diameters. A slip coupling is welded to the upper side of the next joint. The cylinder opposite section is then slide into the coupling where it is welded in the field. This joint type does not contain any threads.

Butt-Weld Joint

The butt-weld cylinder joint is available on all cylinder diameters. Each end of the cylinder section is beveled for welding in the field. This joint type is supplied with bolt lugs to line up and bolt the sections together during assembly and welding. Once welding is complete simply “knock off” or remove the bolt lugs from each joint area.
