To ensure that the flange of the device does not leak oil, the device requests and should pay attention to the following problems:
(1) The stainless steel flange shall have sufficient strength and shall not be deformed during fastening. The flange sealing surface shall be flat and clean, and the oil stain and rust spot shall be cleared carefully during the installation.
(2) the gasket should have excellent oil resistance and anti-aging function, as well as better elasticity and mechanical strength. According to the shape of the joint, the sealing gasket of different sections and sizes shall be selected and placed correctly.
(3) The tightening force of stainless steel flange shall be uniform and inconsistent, and the tightening amount of rubber pad shall be controlled at 1 / 3 left.
In practice, the stainless steel flange shall be stopped in accordance with normal methods and principles to ensure the quality and value type in use and the normal operation specifications and devices. There is no certain quality and function problem. Stainless steel flange is not a kind of simple mechanical parts in the general sense, but a kind of mechanical product carrier containing abundant technology
First of all, the large stainless steel flange shall have enough strength and shall not be deformed during fastening. The flange sealing surface shall be flat and clean, and the oil stain and rust spot shall be cleared carefully during the installation. Large stainless steel flange connection is easy to use and can bear large pressure. In the industrial pipeline, the application of flange connection is very common. In the home, the diameter of the pipe is small, and it is low pressure, and the flange connection cannot be seen. If be in a boiler room or consumption spot, four are the pipeline that flange joins and device.
Secondly, the large stainless steel flange gasket should have excellent oil resistance and anti-aging function, as well as better elasticity and mechanical strength. According to the shape of the joint, the sealing gasket of different sections and sizes shall be selected and placed correctly.
Then, the fastening stress of large stainless steel flange should be uniform, and the tightening amount of rubber pad should be controlled at about 1 / 3.
