Uniones de tuberías MSS SP-83 Clase 3000 y 6000
Detachable / Three-Part Structure / Sealing / Diverse Materials
High Quality Socket Welding and Threaded Pipe Unions
SSM provides pipe unions as a type of connector in pipeline systems, designed to conveniently connect or disconnect two sections of piping. Unlike welding or threaded connections, pipe unions enable disassembly and maintenance without cutting the pipes, making them ideal for scenarios that require frequent disassembly or replacement.
MSS SP-83 Pipe Unions Advantages
Flexibility: Easy to disassemble and reassemble.
Time-Saving: Reduces maintenance and installation time.
Reusability: Can be disassembled and reassembled multiple times.
