Main characteristics of fittings

  • Materials used: Fittings can be made from various materials, including stainless steel, brass, copper, PVC, polyethylene (PE), and polypropylene (PP). The choice of material depends on the application, operating conditions, and resistance requirements.
  • Types: There are different types of fittings, including compression, threaded, welded, flanged, and press fittings. Each type is designed for specific applications and offers different advantages in terms of ease of installation and sealing.
  • Sizes and shapes: Fittings are available in various sizes and shapes, such as elbows, tees, crosses, reducers, and straight couplings, to fit different piping system configurations.
  • Corrosion resistance: Corrosion resistance is a critical feature for fittings used in aggressive environments or for transporting corrosive fluids. Materials like stainless steel and PVC offer excellent anti-corrosion properties.
  • Pressure and temperature: Fittings must be designed to withstand the system’s operating pressures and temperatures. High-pressure and high-temperature fittings are available for demanding applications.

 

How fittings work

  • Pipe connection: Fittings are used to connect pipes and ducts within a system. They can be threaded, welded, compressed, or pressed to create a secure and leak-proof connection.
  • Direction change: Elbows and bends are used to change the flow direction in piping systems, allowing for a flexible and adaptable configuration.
  • Flow distribution: Tees, crosses, and reducers distribute fluid and gas flow to multiple points within the system, ensuring uniform distribution.
  • Size adaptation: Reducers and adapters are used to connect pipes of different sizes, allowing compatibility between components of various dimensions.
  • Isolation and maintenance: Shut-off valves and maintenance joints are used to isolate sections of the system for maintenance and repairs without interrupting the entire system.

 

Fittings: the latest innovations

  • Advanced materials: The use of advanced materials and special alloys is improving the strength and durability of fittings, offering superior performance under extreme operating conditions.
  • Manufacturing technologies: The adoption of advanced manufacturing technologies, such as 3D printing and CNC machining, allows for the production of fittings with high precision and customization.
  • Eco-friendly finishes: New environmentally friendly surface finishing technologies are emerging, reducing the environmental impact of fitting production.
  • Smart connection systems: The development of smart connection systems, with integrated sensors for monitoring stress and operating conditions, is revolutionizing the use of fittings in complex systems.

Fittings are crucial components in piping systems, ensuring efficiency, safety, and durability across various applications.
