FAQ – Technical & Selection Guide

Tri-Clamp vs. Threaded Sanitary Unions – difference?

Tri-Clamps enable tool-free rapid disassembly for daily cleaning lines. Threaded hygienic couplings provide wrench-tightened high-strength connections, ideal for heavy pump vibrations and extreme temperatures.

304 or 316L stainless steel – how to choose?

Food & beverage systems typically use 304. Pharmaceutical, high-purity water, or corrosive media require 316L for superior corrosion resistance and cleanability.

CIP / SIP system compatibility?

Yes, sanitary unions are fully compatible with CIP (clean-in-place) and SIP (steam-in-place) systems. Confirm temperature, pressure ranges, and sealing material compatibility.

Non-standard & custom solutions?

Custom sizes, connections, materials offered according to drawings, samples, or technical specifications. OEM/ODM supported.

Material certification documents?

EN 10204 3.1 material certificates and test reports (PMI, roughness, hardness) are provided with every shipment.
