How to better use washers and selection standards for EPDM flat washers?

fastenerHow canEPDM flat washersbe better used:

1. In harsh environments, it is recommended to seal theflat washerto prevent leakage during working hours at a certain temperature and pressure.

2. When connecting the flat washer and the contact surface, it is necessary to better ensure sealing, just like the just good effect.

3.Remember to ensure normal use at relative temperatures when using flat pads.

A EPDM flat washer is a type of flat washer, mainly used to increase the contact area betweenscrewsand some large equipment and tighten them. When using a flat washer, it is often suitable fornutsand nuts to be used together. When storing a flat washer, it is important to ensure the most effective sealing time. When selecting a flat washer, it is best to choose a flat washer that is coated with rust and corrosion resistant materials. This not only saves time and effort, but also allows the flat washer to play its best role.

When used withboltsand nuts, the selection criteria for flat washers are:

fasteners

1. When selecting washer materials, attention should be paid to the issue of electrochemical corrosion when different metals come into contact. The material of the flat pad is generally the same as the material of the connected part, usually steel, alloy steel, stainless steel, aluminum alloy, etc. When there is a requirement for conductivity, copper and copper alloys can be selected.

2. The inner diameter size of the flat washer should be selected based on the larger value of the thread or screw diameter, and the larger value should be selected for the outer diameter of the connected material that is soft (such as composite material) or compatible with thespring washer.

3. When choosing to place the W washer under the bolt orscrewhead, to avoid interference between the fillet under the head and the washer, aEPDM flat washerwith an inner hole chamfer can be selected.

4. For important bolts with larger diameters or to increase their resistance to compression,steel washersshould be used. Steel washers should be used for the connection of tension bolts or tension shear composite bolts.
