Insulation Joints

Single(1) Point Welding type Insulation Joint

None-Welded type Insulation Joint
(International patented products)

The Industry’s Best Sealing

The ElectroLoc® monolithic Insulation joints manufactured by TAEWON will serve as a positive, leak-proof, block against the flow of electric current in all piping systems. When you buy the ElectroLoc® Insulation joint you also buy maintenance costs; an especially important feature for system operators and engineers.

Eliminates Short Circuits

Bolts, sleeves and washers – the major source of short circuits in most Insulation assemblies are eliminated with the ElectroLoc® Insulation joint. Each joint is electrically tested during production to assure integrity, performance, isolating properties.

Eliminates Field Assembly

The ElectroLoc® Insulation joint is 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.

100% Shop Tested

All ElectroLoc® Insulation joints undergo shop tests according to project specifications and code requirements.
The undergo shop test is shown below.
