sanitary coulings

Sanitary Couplings

Stainless steel sanitary couplings for screw pipe connections and for expanding and welding are made for use of the transfer of food, beverage, chemical or pharmaceutical particles in food and chemical industry. The couplings, split clamps and crimping ferrules are designed and produced based on DIN 11851, French Macon and SMS 1145, and BS 4825 / DIN 32676 / ISO 2852 for Tri-Clamp connection types.

Male couplings with (RD) thread and female coupling with cone head (liner) are compressed with food-grade sealing material in between and closed by a round screw-on nut.

Connecting Types

Hose end types are made for a) butt welding (BW) long and short versions, with and without double internal grooves, and b) for coupling assembly with DIN Bolted Clamps to EN 14420-3. Dust plugs are available with (RD) thread and cone trimming shapes.

Surface Finish Roughness Ra-Value

Inner tube roughness, per DIN 11851 for instance, is made to Ra ≤ 0.8 µm; outer rube finish to Ra ≤ 1.6 µm as on highest-precision machines followed by ultrasonic cleaning process.

Innov-X Alloys and Metals Analyzer

Stainless steel AISI 304 (1.4301), AISI 316 (1.4401) and AISI 316L (1.4404) bar stock are sourced and controlled throughout production. Final products are double confirmed using spectrum analyzer before inventory. We are using a handheld Olympus Innov-X Alloys and Metals Analyzer that identifies alloy grades of esp. stainless steel and copper alloys in seconds. With its in-built material database the result is automatically made and instantly read so that we are able to approve the quality beyond eyes right before shipping.
