Electric bending
The electrical bending test examines the installation and usage requirements of the product, this test has the ability to test on samples of gas and water ball valves from size 1/2“ to size 4“. These products are subjected to bending stresses both during installation and after installation.
Description
User tensions
Regarding user stresses, an important point is that when a valve is placed in a place on the pipe during the connection of the outlet pipe, if the end of the outlet pipe has a slight bend in relation to the direction of the valve, after connecting that pipe to the valve, permanent bending stress is transferred to the valve. slow. And the gas or blue product must have the ability to withstand this permanent bending stress.
