Pipe couplings (or couplers) are short lengths of pipe or tube designed to connect two tubes of equal or different sizes. It features either a socket or female threads at one or both ends. This essential pipe fitting aids in extending or terminating pipe runs, changing pipe sizes, and repairing broken or leaking pipes.
Over time, most pipe installations require several pipe lengths to join or cut to navigate changes in direction and cross obstacles. Pipeline couplings offer a simple and effective solution for connecting these sections while preserving the integrity and continuity of the pipes.
1. Coupling Material
The pipe coupler's materials include carbon steel, stainless steel, and more. In general, the materials of coupling connectors match or resemble the composition of the pipes they connect.
-
Stainless steel coupling
Stainless steel couplings usually use 304 or 316 stainless steel.
They have high anti-corrosion properties even in harsh environments.
High durability and high-temperature resistance.
Stainless steel is ideal for the food, drink, and medicine industries due to its hygiene and easy cleaning.
-
Galvanized coupling
The galvanized coating on the surface of the coupling can enhance the corrosion resistance.
The galvanized pipe coupling is suitable for outdoor or wet environments.
-
Black pipe coupling
A black pipe coupling coats black oxide during manufacturing and has a certain degree of anti-corrosion properties.
Lower price, durable.
Black pipe coupling corrosion resistance is limited and needs extra protection.
2. Key Characteristics of Pipe Couplings
-
Flexibility
They can be rigid or flexible based on the movement they can withstand. Couplings can also be either permanent or removable.
-
Increased or Decreased Diameter
Some coupling for pipes allows for changes in internal diameter to join pipes of different sizes.
-
T or Cross-Shaped
These can connect more than two pipes.
-
Angled
Some couplings are designed to create bends in piping systems.
3. Types of Threaded Pipe Couplings
-
Full Coupling
Full coupling connected with two same-diameter pipes ensures no leakage.
Full merchant coupling usually connects to small bore pipes.
Full merchant coupling connects pipe to pipe or pipe to swage nipple with threaded ends.
It is an adapter often called when the ends differ (like BSP and NPT).
-
Half Coupling
Half coupling is connecting one coupling with another coupling or facility.
Half coupling is ideal for small bore branching from vessels or large pipes.
Half coupling is shorter than full couplings and also features threaded ends.
-
Reducer Coupling
Reducer coupling connects with different diameter pipes.
Reducer coupling enables connection between pipes of different diameters.
Reducing coupling, which is a coupling that connects a 3/4" NPT pipe to a 1/2" NPT pipe.
Reducer coupling is commonly where small process feeder lines merge with larger supply circuits.
4. Benefits
-
prevent leak
Coupling pipes can ensure tight seals and decrease the leak risk to maintain system integrity.
The coupling thread enhances the reliability of the high-pressure system.
-
cost-effective
Coupler decreases the complex welding, saving time and force cost.
Steel coupling simplifies the repairs and extends the service life of the piping system.
-
