TC Ferrule SW
What is a TC Ferrule SW?
A TC Ferrule SW (Socket Weld) is a sanitary fitting designed to be welded directly to process piping for a seamless and crevice-free connection. Unlike clamp-based ferrules, the socket weld version ensures rigid, permanent joints ideal for systems with high mechanical stress or thermal cycling.
Asaid Steel Industries is a premium TC Ferrule SW supplier, offering socket weld ferrules in SS 304 and SS 316L, precisely machined to comply with international sanitary norms.

Do you have questions?
TC Ferrule SW is used for socket welding onto pipes where permanent, sanitary-grade joints are needed. It’s ideal for high-pressure, vibration-prone applications.
Unlike clamp-based ferrules (male/female), TC Ferrule SW is designed for socket welding to ensure a fixed, crevice-free connection.
Yes. With SS 316L and mirror-polished interiors, it supports CIP, SIP, and sterile process systems without risk of contamination.
Yes. The socket weld ferrule still mates with a clamp and gasket system on its open end, allowing standard tri-clamp connections.
