What kind of gasket is used for electromagnetic flowmeter flange?

Case introduction

The selection of flange sealing gasket for electromagnetic flowmeter should be based on the pressure of the flange, the operating temperature and the type of medium flowing in the pipeline. Common sealing gasket materials include:

Asbestos rubber gasket: It has good elasticity and is suitable for flange connections with large expansion. However, considering the environmental pollution problem, it needs to be selected carefully.

PTFE (polytetrafluoroethylene) gasket: has excellent temperature resistance and corrosion resistance, and is suitable for high temperature and corrosive media environments.

Red rubber gasket: cheap, good sealing performance, but poor pressure and temperature resistance, not suitable for high temperature and high pressure environments.

Rubber gasket: Suitable for general industrial applications, with good elasticity and sealing properties, but suitable for working environments with temperatures between -20°C and 80°C.

Metal gasket: suitable for high temperature environments and can withstand media with high temperatures up to 800°C, but the cost is higher.

Copper gasket: usually used in high temperature and high pressure environments, with good thermal conductivity and corrosion resistance.

Graphite gasket: suitable for special working conditions of high temperature and high pressure, with good corrosion resistance and high temperature resistance.

When selecting the flange sealing gasket of the electromagnetic flowmeter, the flow rate, pressure and other parameters of the medium should be considered, and the appropriate gasket material and thickness should be selected to ensure the sealing performance and normal operation of the flange connection. . At the same time, when installing the gasket, ensure that the dimensions match, and follow the correct steps for installation and tightening to prevent media leakage and ensure measurement accuracy. Regular inspection and replacement of gaskets are also important measures to maintain the normal operation of the electromagnetic flowmeter.
