Dairy Pipe Clamps
What are Dairy Pipe Clamps?
Dairy Pipe Clamps are sanitary fittings used to securely join two ferrule-ended components in hygienic piping systems. Designed for quick assembly and disassembly, these clamps ensure leak-proof connections in processing environments requiring regular cleaning or maintenance.
Asiad Steel Industries is a trusted manufacturer and exporter of dairy clamps, fabricated from premium-grade stainless steel. Our clamps are available in single-pin, double-pin, and heavy-duty variants to suit different operating pressures and applications.
