Spring Washer 65MN spring steel,70# carbon steel, 3Cr13, stainless steel materials SUS304 or SUS316,phosphor bronze materials
Spring washers are used to prevent loosening. For example, spring washers are generally added to the bolts connecting the motor and the base, because if there is no spring washer, the nut will loosen due to motor vibration. Generally, spring washers are installed on the fasteners of equipment with vibration, and gaskets are generally not required on the flange.
Whether to add spring washers to the flange is related to the medium flowing through the pipeline. If it is easy to generate pulses, it is best to add spring washers. There are also high-speed fluid pipelines with frequent changes in caliber, so don’t generalize. On some valves, spring washers are required for the stuffing box gland flange. The quick and easy selection of spring washers is included.
Material: Usually 65MN spring steel or 70# carbon steel, 3Cr13, stainless steel materials SUS304 or SUS316, and phosphor bronze materials can also be used.
