Introduction
Silicone sealing gasket is a high-performance sealing material made of silicone rubber with excellent high-temperature resistance, low-temperature resistance, oxidation resistance, radiation resistance, and chemical corrosion resistance.
It can be used to seal various pipes, containers, valves, and other equipment to prevent the leakage of gas, liquid, dust, and other substances and ensure the normal operation and safety of the equipment.
Design Structure
1. Gasket body: usually a round or square sheet made of silicone material. The thickness and size of this body will be designed based on application needs and equipment specifications. The main part will have a certain degree of elasticity to adapt to irregular or rough sealing surfaces to ensure a good sealing effect.
2. Connection part: The design of the connection part will vary according to the installation method of the gasket and the use environment. For example, a silicone sealing gasket is designed with notches or holes in the edges so that they can be bolted or clamped to the device. There are also silicone gaskets that are adhered to the device using adhesive or pressure-sensitive tape.
Specification
The specifications of silicone gaskets are usually determined based on their inner diameter, outer diameter, and thickness. The following are common specification ranges:
1. DN15-DN50: The outer diameter of the silicone sealing gasket is usually 23mm, the inner diameter is usually 15mm, and the thickness is usually 2mm.
2. DN65-DN100: The outer diameter of the silicone rubber gasket is usually 77mm, the inner diameter is usually 65mm, and the thickness is usually 2mm or 3mm.
3. DN125-DN200: The outer diameter of the silicone rubber gasket is usually 153mm, the inner diameter is usually 125mm, and the thickness is usually 3mm or 4mm.
In addition, the prices of silicone sealing gaskets of different sizes will also vary.
