KF stainless steel simple high-pressure reaction kettle is a simple high-pressure reaction kettle produced according to the functional characteristics of the high-pressure reaction kettle according to customer needs. It can be placed in environments such as electric blast drying oven, constant temperature oil/water bath, low-temperature bath, etc. The kettle body and lid are generally made of 304 or 316 stainless steel, and the material can also be changed according to customer needs. The kettle body is connected to the flange through threads, and the kettle cover is a regular flat plate cover. The two are fastened together by main bolts and nuts evenly distributed in the circumferential direction. The main sealing seal of the high-pressure reactor adopts A-type double line sealing, and the other sealing points adopt the sealing form of circular arc surface to plane and circular arc surface to circular arc surface line contact. By relying on the high precision and smoothness of the contact surface, a good sealing effect is achieved. Can be configured with computer communication terminals, and the volume size can be customized according to customer needs.
