ALFA Monolithic Isolation Joints are boltless and completely factory assembled in accordance with the appropriate requirements of ASTM, API, DIN and BS codes.  All welds are butt weld construction.

The dielectric isolation material are made of a thermosetting fiberglass epoxy material. Sealing is performed with double self energized “O” rings housed in accurately machined grooves, fully protected from cavitation in full compliance with ASME design codes.

Interior and exterior coating is a two part epoxy with 300 mm epoxy within 2 inch of each end.

Each isolation joint is electrically tested @ 5 kV, and 200 Mohm isolation test. Each isolation is also hydrostatically tested @ 1.5 x D.P.

All welds are subject to Ultrasonic/MPI/DP and Xray examination.

 
 

Quality Assurance

Each Monolithic Isolation Joint is designed and manufactured at our plants in Bastiglia (Italy) that has a registeredISO 9001:2000 Quality Management System.

Copy of current ISO 9001:2000 certificate is available upon request.

WHY TO USE MONOLITHIC ISOLATION JOINTS

ALFA Isolation Joints serve as a positive leak proof, long lasting block against the flow of electric current in all piping systems. When you put ALFA Isolation Joints into service , you bury maintenance cost forever.

 

SOME FEATURES FOR SYSTEM OPERATORS AND ENGINEERS

Eliminates Short Circuits

Bolts, sleeves and washers, the major cause of short circuits in most isolation assemblies are eliminated when using ALFA Monolithic Isolation Joints.

Eliminates Field Assembly

ALFA Monolithic Isolation Joints are completely factory assembled and tested. There are no flanges,gaskets, nuts, bolts, sleeves or washers to handle and consequently no fluid leaks due to improper field assembly.

Less Expensive

You can purchase ALFA Monolithic Isolation Joints for less than the cost of the component parts of insulated flange assemblies in most pipe sizes. You can install ALFA Monolithic Isolation Joints for less than the labor costs of installing and insulated flange assembly.
