International standard
ISO 2852
Stainless steel clamp pipe couplings for the food industry
[1]
was an
international standard
that defines a non-permanent sanitary food-grade piping interconnect method, commonly used in the
food processing
industry and with
dairy farm
equipment.
The interconnect consists of:
- a lip flange on the ends of pipes with a grooved indentation on the flange.
- a polymer sealing
gasket
placed between sections of pipe, squeezed between the flanges. This ring has a raised groove on both sides mating with the indentations of the two pipes on either side.
- an enclosing clamp with C-shape clamping sections that cover the outer circumference of the flanges, applying pressure to squeeze the two pipe sections together onto the sealing ring. The clamp also provides structural strength and rigidity to the pipe sections.
The combined lip flange and gasket do not impede the flow of fluids through the piping.
The clamping system may be permanent, using a
hose clamp
style screw and band, or it may be easily removable using a fold-over hinged clamp assembly.
ISO 2852 is withdrawn as international standard since 31 July 2018.

Companies that supply products according to the specifications of ISO 2852 do not necessarily mention the ISO standard as such, instead referring to the equipment by terms common in the relevant industries or applications. Examples include:
- Tri-Clamp Fittings
[2]
- Tri-Clover Fittings
[3]
- S-clamp fitting
- Sanitary Fittings
[4]
- 3A pipe fitting (This terminology includes other types of fittings. "3-A" is a set of standards for
cleanability
and inspection of dairy equipment, developed by 3-A Sanitary Standards, Inc.
