As an example, a gas utility wanted to know if a bending stress would cause failure at the outlet of a particular service fitting, the gas utility would prepare the assemblies and ship them to Jana, which developed a bending jig to duplicate the field bending
When contract documents don't show that field bending of embedded bars is planned, the problem is getting permission of the licensed design professional.
This roughly simulates the procedure of using a hickey bar for field bending.
The deep socket allows more joint deflection for cold field bending
than injection molded couplings and Standard socket depth couplings.
This tough outer coating also retains a high degree of flexibility that exceeds specification limits of steel for field bending
