Can you recommend different hygienic clamp/nut configurations for these different applications?

Steam only (hygienic connections are infrequently removed and reassembled.) A basic stainless-steel clamp designed for hygienic connections, such as the Advanced Couplings SH Series clamp, can provide quick access to the joint for cleaning and inspection without compromising safety.

Hygienic gas only (e.g. air, nitrogen: hygienic connections are infrequently removed and reassembled). The above-mentioned clamp can be used here, or a high-pressure version with two bolts for greater clamping force.

Process fluids (e.g. liquid product streams, CIP fluids, and SIP conditions) – Operations personnel remove and reassemble the connection every batch. An anti-galling clamp is ideal for these applications to prevent the metal from fusing.

Process fluids (see liquid product streams, CIP fluids, and SIP conditions) – Operations personnel only remove and reassemble the connection for infrequent maintenance activities. We recommend the SH series clamp above.
