The grooved joint method is simpler and faster than welding in the field. To relieve the stress of the piping, change the orientation of the piping or use the joint to secure the piping.
- Joint material: Spherical graphite cast iron(ASTM A536, GCD450)
- Gasket Material: EPDM
- Bolt/nut material: Carbon steel for mechanical structures
- Painting: Epoxy Powder Painting
The grooved joint method is simpler and faster than welding in the field.
To relieve the stress of the piping, change the orientation of the piping or use the joint to secure the piping.
The Model XGQT1B Reducing Coupling allows direct reduction on a piping run and eliminates the need for a concentric reducer and couplings. The specially designed rubber gasket prevents the smaller pipe from telescoping into the larger pipe during vertical installation. All XGQT1B couplings are comprised of two identical housing segments, EPDM rubber gasket and plated track bolts and nuts.
XGQT1B couplings should always be installed so that the coupling bolt pads make metal to metal contact.
The Model XGQT1B couplings must not be used with an end cap, as the end cap could be sucked into the pipe by the vacuum created when a system is being drained.
