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

How can EPDM flat washers be better used:

1. In harsh environments, it is recommended to seal the flat washer to 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 between screws and some large equipment and tighten them. When using a flat washer, it is often suitable for nuts and 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 with bolts and nuts, the selection criteria for flat washers are:

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 the spring washer.

3. When choosing to place the W washer under the bolt or screw head, to avoid interference between the fillet under the head and the washer, a EPDM flat washer with an inner hole chamfer can be selected.

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