Coupling

A coupling is a device used to connect two shafts together at their ends for the purpose of transmitting power.

A coupling is a mechanical device used to connect two shafts together at their ends for the purpose of transmitting power. Couplings are essential in various industrial and mechanical systems to ensure that power can be transmitted efficiently and reliably from one component to another. There are several types of couplings, each designed for specific applications and conditions.

Pipe couplings are highly demanded in the pipe fitting market. Pipe couplings are fittings that help to extend or terminate pipe runs. These fittings are also used to change pipe size. Couplings extend a run by joining two lengths of pipe. They are known as reduced coupling if they are used to connect pipes of different sizes.

Couplings are critical in ensuring the longevity and efficiency of mechanical systems. They are often chosen based on the specific needs of the application, such as the amount of torque that needs to be transmitted, the level of flexibility required, and the operating conditions.

Couplings are also known as repair couplings. These couplings are without stops or ridges and they can be fixed anywhere along the pipe length for preventing leak of any kind.

Designs on couplings

Application

Besides being used as an important pipe fitting, couplings are also used in the following:

Coupling usage

Pipe couplings are primarily used to join two or more sections of pipes together. They provide a secure and leak-proof connection, ensuring the continuity of fluid or gas flow in the piping system.

  • Machine tools
  • Assembly machinery
  • Industrial robots
  • Automated plants
  • Printing machinery
  • Servo drives
  • Robotic axes
Coupling usage

Couplings are often used for pipe repair and maintenance. They allow for the quick and easy replacement of damaged or corroded sections of pipe without the need for extensive cutting or welding.

  • Manipulators
  • CNC milling / grinding
  • Linear actuators
  • Packaging machinery
  • Woodworking machinery
  • Textile machinery
  • Printing machinery
  • Metal cutting machinery etc.

Any type of packing is available according to customer need to worldwide destinations.

  • For roadfreight in timber fingers or skids.
  • In strong open or closed wooden boxes depending destination.
  • Each bundle is protected with plastic sheets.
  • Customers can provide their own packing or Salem can prepare a packing plan.
  • Detailed packings lists are attached to wooden cases to give quick and clear identification of contents.

【H】 Ceramic lined pipe

Ceramic lined pipe is made through self-propagating high-temperature synthesis (SHS) technique.

【H】 Cast basalt lined steel pipe

Cast basalt lined steel pipe is composed by lined with cast basalt pipe, outside steel pipe and cement mortar filling between the two layers.

【H】 Ceramic Tile Lined Pipes

Ceramic tile lined pipes have very uniform coating of specially formulated ceramic material that is affixed to the inner of the pipe.

【H】 Rare earth alloy wear-resistant pipe

The material of the rare earth alloy wear-resistant pipe is ZG40CrMnMoNiSiRe, which is also the grade of rare earth alloy steel.

【H】 Tubes Erosion Shields

Tubes Erosion Shields are used to protect boiler tubing from the highly erosive effects of high temperatures and pressures thereby greatly extending tube life.

【H】 ASTM A213 T91 Alloy Tube

The ASTM A213 T91 seamless tubes are primarily used for boiler, superheater, and heat-exchanger.
