What is a dresser coupling?
Dresser couplings are the original and best compression type pipe joining device. Allowing slight misalignment, vibration, expansion and contraction with a very simple and rapid installation process. If you can do up a nut and bolt you are capable of installing a Dresser coupling.
What is a coupling used for in piping?
Coupling & Adapter Fittings – Pipe couplers slip over the outside of two pipes to connect them, usually permanently. A coupling can be a reducer, or reducing coupling, meaning they reduce flow by joining a larger pipe to a smaller size. Adapters are used when connecting two pipes of different types.
What is a coupling on a water pipe?
In water and wastewater piping systems, pipe couplings are used to connect two or more sections of pipe with the aim of maintaining continuity between them. They can be used to join pipes of different or equal sizes, as well as connect more than just two pipes if they are cross or T-shaped.
What is a mechanical coupling for pipes?
The coupling and flange adaptor will function as mechanical pipe joints for us in pipelines to facilitate the removal of valves and fittings without disturbing the pipelines and accommodate limited ground movement, expansion, contraction and angular misalignment of the pipeline.
Are dresser couplings restrained?
The time-proven Dresser Style 90 insulated restraining coupling was designed with strength, protection, and insulation in mind. This coupling is ideal when efficiency is necessary – making quick pipe joints when both positive restraint and electrical isolation are required.
Is there a difference between a coupling and a coupler?
A coupling (or coupler) (used in piping or plumbing) is a very short length of pipe or tube, with a socket at one or both ends that allows two pipes or tubes to be joined, welded (steel), brazed or soldered (copper, brass etc.) together.
What is a Megalug fitting?
The Series 1100 MEGALUG® Mechanical Joint Restraints effectively and economically restrain Ductile Iron Pipe (DIP) to mechanical joints above or below ground, for practically any application including valves, hydrants, and pipe.
Can I use a PVC compression coupling on galvanized pipe?
A Dresser coupling — made by the Dresser Company — is a compression coupling you can use to repair galvanized steel and other metal pipes. They can connect pipes with or without threads and are especially useful when threads have rusted and become unusable.
