Hygienic Tube and Fittings

To facilitate installation of Diamond valves, Dairy Pipe Lines (DPL) provides a comprehensive range of hygienic stainless steel tube and fittings for every processing application.

Where product pipelines have to be dismantled frequently for cleaning, a crevice free union provides the optimum hygienic solution. In such applications, swift and easy disconnection and re assembly is important, since it will not only help to reduce the time and effort involved in the cleaning or sterilization process, but also cut costs.

Our range of unions comprises the ILC, Clamp, RJT and IDF. Constructed from 316 and/or 316L stainless steel, they are available with a range of seal materials, including Nitrile, Silicone, EPDM, Viton and PTFE, to ensure compatibility with customer process system applications.

To complement this extensive range of fittings, we supply AISI 316/304 stainless steel tube in sizes from ½ inch to 4 inch (exterior dimensions). Stocked in 6m random lengths, the tube comes with polished or bright unannealed finishes.

Plain bends and tees conform to ISO standards and BS 4825 PT 3 for orbital or hand welding on site, while crosses and ‘Y’ pieces can be manufactured to customer specifications and drawings and supplied with or without fittings.

Stainless steel filters – including side entry, in-line, ‘Y’ type and pump protection systems, along with a duplex assembly set up for use with our plug and butterfly valves – help to ensure product in the pipeline remains free from foreign bodies and oversize solids.

Hygienic Slimline Ball Valve

The Diamond SLIMLINE Ball Valve is a high quality, compact, on/off unit offering you space-saving.
