TriClamp coupling in accordance with DIN 32676

TriClamp connections in accordance with DIN 32676 are detachable clamp connections for hygienic pipework systems. They connect pipes and system components quickly and are used in particular in the food and beverage industry, as well as in the pharmaceutical and biotechnology sectors. The connection size, material, seal and operating conditions are crucial in determining the appropriate design.

Description

Description of a TriClamp connection

A TriClamp fitting is a detachable pipe connection for hygienic process systems. It consists of two clamping sockets, a gasket and a clamp. The gasket is positioned between the sealing surfaces, whilst the clamp connects the clamping sockets and generates the necessary clamping force.

TriClamp connections are used, amongst other things, in the food and drink industry, in dairies and breweries, as well as in the pharmaceutical, biotechnology and cosmetics industries. Their detachable design facilitates assembly, disassembly and maintenance work.

The appropriate design depends on the connection size, standard series, material, seal material, process medium, pressure and temperature. Always check the specifications in the relevant product data sheet and the seal’s compatibility with the specific process before use.

Function

Function of a TriClamp connection

The TriClamp connection seals pipework and system components using a gasket inserted between two clamping sockets. During assembly, the connection ends are aligned, the gasket is centred, and the clamp is placed over both ends and closed evenly. The clamping force presses the sealing surfaces against the gasket.

To ensure a reliable seal, the sealing surfaces must be clean, undamaged and correctly aligned. Before assembly, the gasket, clamping sockets and clamp must be checked for dirt, damage and wear. Damaged components must be replaced. The product-specific assembly instructions and permissible pressure and temperature limits must be observed.

FAQ: Clino Stainless Steel Aseptic Connections

Description of a TriClamp Fitting

The TriClamp fitting is a hygienic pipe connection used primarily in the food, beverage, pharmaceutical, and biotechnology industries. It consists of two clamping sockets, a gasket, and a clamp, which securely connects the components. Its simple design allows for quick assembly, disassembly, and cleaning.

How does a TriClamp fitting work?

The seal is provided by a gasket inserted between the two flange ends. Tightening the TriClamp clamp compresses the flanges evenly, causing the gasket to deform and creating a secure, leak-free connection. If necessary, the connection can be quickly disassembled and reassembled without damaging the piping system.

Where can a TriClamp fitting be used?

TriClamp fittings are used wherever there are high standards for hygiene, cleanability, and product safety. Typical applications include:

  • Food and beverage industry
  • Dairies and breweries
  • Pharmaceutical industry
  • Biotechnology
  • Cosmetics industry
  • Chemical process engineering
What distinctions are there within the product line?

TriClamp connections differ, among other things, in:

  • Nominal diameters and connection sizes
  • Materials (e.g., stainless steel 1.4404 / AISI 316L)
  • Seal materials (EPDM, NBR, FKM/FPM, silicone, PTFE, etc.)
  • Surface qualities and roughness values
  • Clamp designs (one-piece or two-piece, with wing nut or clamping nut)
  • Standards and specifications for various applications
What are the advantages of a TriClamp fitting?
  • High-quality stainless steel designs for demanding applications
  • Hygienic design with minimal dead space
  • Quick and easy assembly and disassembly
  • Easy to clean
  • Extensive product range with high availability
  • Suitable sealing solutions for a wide variety of media and processes
  • High manufacturing quality and process reliability
What are the technical specifications (pressures, temperatures, media, etc.)?

The permissible operating pressures and temperatures depend on several factors:

  • Nominal diameter of the connection
  • Material of the connection components
  • Seal material used
  • Operating medium
  • Process and environmental conditions

TriClamp fittings are suitable for liquid media. The exact pressure and temperature limits can be found in the respective product data sheets. The material and media compatibility of the seals used must be verified prior to use.

How do you properly install a TriClamp fitting?
  • Check the sealing surfaces for cleanliness and damage.
  • Position a suitable gasket in the center between the flange ends.
  • Align the flange ends precisely.
  • Place the TriClamp clamp over the flange edges.
  • Tighten the clamp evenly until the connection is securely fastened.
  • After installation, check the connection for proper fit and tightness.

To ensure long-term, reliable operation, use only undamaged gaskets and clamps.
