What Is A Pipe Coupling?

Pipe couplings, also known as couplers, are short segments of pipe or tubing designed to connect two tubes—whether they’re of equal or differing sizes. These essential fittings feature either a socket or female threads at one or both ends. Their primary purpose is to extend or terminate pipe runs, change pipe sizes, or repair damaged or leaking pipes. Over time, most pipe installations require multiple lengths of pipe to be joined or cut to navigate changes in direction or cross obstacles. Pipeline couplings provide a straightforward yet effective solution for connecting these sections while maintaining the integrity and continuity of the pipes. ### Key Characteristics of Pipe Couplings #### Material: The materials used for pipe couplings include carbon steel, stainless steel, and other durable options. Typically, the material of the coupling matches or closely resembles the composition of the pipes it connects. #### Flexibility and Types: Depending on the level of movement they can accommodate, couplings can be rigid or flexible. They can also be either permanent or removable, offering versatility for various applications. #### Increased or Decreased Diameter: Some couplings allow for changes in internal diameter, enabling the connection of pipes of different sizes. #### T or Cross-Shaped: These couplings can connect more than two pipes, making them ideal for complex piping layouts. #### Angled: Certain couplings are specifically designed to create bends in piping systems, allowing for intricate designs.

[Insert relevant images here] #### Half Merchant Coupling: - **Usage:** Perfect for small-bore branching from vessels or large pipes. - **Characteristics:** Shorter than full couplings and features threaded ends. [Insert relevant images here] #### Reducing Coupling: - **Usage:** Allows the connection of pipes with different diameters. - **Example:** A coupling that connects a 3/4” NPT pipe to a 1/2” NPT pipe. - **Application:** Commonly used where small process feeder lines merge with larger supply circuits.

Their strength, versatility, robust flow rates, and high chemical tolerance make them particularly suited for: - **Industrial Applications:** Used in firefighting systems, heating, and air supply/removal. - **Marine Use:** Essential for freshwater and seawater storage on ships and offshore facilities. - **Power Generation:** Utilized in cooling return tanks, lubrication tanks, and compressed air tubes in power plants. - **Manufacturing and Structural Engineering:** Commonly employed in plant maintenance, water and gas delivery systems, and various engineering projects. - **Auto Repair:** The muffler pipe coupler connects sections of the vehicle’s exhaust system, ensuring airtightness. Pipe couplings have become indispensable in many settings due to their ability to offer secure, robust seals while maintaining flexibility. ### Pipes and Fittings Supplier #### Highlight: Hebei Sanvo is a leading manufacturer and supplier of pipe couplings in China.

IECEx Approved Coriolis Mass Flow Meter

Zhejiang Sealand Technology Co., Ltd. is a trustworthy manufacturer of Mass Flow Transmitter, Coriolis Mass Flow Transmitter, Coriolis Mass Flow Sensor, Mass Flow Sensor & Mass Flow Sensor Coriolis, ATEX, IECEx & CE approved.


The meter can be connected with computer as follows. Connect the meter and computer with a USB-to-RS485 converter( converter A+ end to transmitter A+ end, B- to B-, and GND to GDN); turn to device manager of the computer to check COM port connected with meter. Start the software, select the right COM port and click Connect; do not change any other parameters (if you do not know the right one, click Automatic options on the left, click Connect, plug & unplug the transmitter, and then check if it is connected). You can click Connect on the tool bar to disconnect or connect again. It will shown Connected/Not Connected at the bottom of this interface.


The flow direction is settable. There are 4 options, forward(default), reverse, absolute value & bi-direction. There is a direction mark on the sensor. Forward means the same direction with the mark on sensor, the meter will only count the flow in this direction; reverse means the opposite direction of the mark, the meter will only count the reverse direction; bidirectional means that the meter will measure both directions, it increases when it is forward and decreases when reverse; absolute means it increases no matter it is forward or reverse.
