Duplex springs are magnetic and resistant to corrosion than other springs. They are used in commercial, residential, self storage, truck body doors and rolling steels. They can also be used for making spring products such as wave springs, compression springs and retaining springs.
Main features of Duplex Springs
They have good weldability
Better pitting resistance than stainless steels
Uniform corrosion resistance
Duplex Springs Application
They are used in:
Oil and gas industries
Chemical processing plants
Tools used to control pollution
Duplex Springs Manufacture
They are made of special steel, double wound and they have a protective spring cover that is flexible. Duplex springs can be used to replace broken or worn springs in any handpiece. These springs give extra flexibility to any handpiece when you require specific control for important work. It is important to constantly lubricate duplex spring components to keep them functional.
It is recommended that these springs be handled by users with some experience in flex shaft tools and those whose jobs require extra flexibility because they are not covered by any warranty, and they can easily break.
To choose the proper spring, you need these elements:
The size of the wire:
Length of the spring
The left and right wind of the spring
The size of the wire can be determined by many tools such as callipers, wire gauge and micrometer. If you don’t have any of these tools, you can use ten coils of wire to measure.
Duplex Springs Use and Replacement
One way to determine if a duplex spring needs replacement is to take a look at the inner spring. Also, you can weigh the overhead door. For a door, if it closes it should weigh 20 pounds, so, if it weighs more than that, it means that you have a broken spring. Another way of doing this is to observe the stationary cones. If there is a break, the coil will wind more onto the cone.
