How to install stainless steel flanges in pipes

Stainless steel flange connection is an important connection mode in pipeline construction, mainly used for pipeline installation and connection, has a high application value. Stainless steel flange connection is to fix two pipes, pipe fittings or equipment respectively between two flange plates or a flange plate, add flange pad, bolted together to complete the connection. The following small series to briefly say the importance of rust steel flange in pipeline connection.
Stainless steel flange is a kind of pipe with a neck transition and pipe butt welding connection, stainless steel flange as a disk parts, in pipeline engineering is very common, in pipeline engineering, the use of stainless steel flange is mainly used for pipeline connection.
Due to the nominal pipe diameter and nominal diameter of the vessel or cylinder represents the detailed size of each different, so with the same nominal diameter of the vessel is stainless steel flange, and they are roughly the same size, so they can replace each other, in any environment, mostly to stop processing of stainless steel flange some segment of share out bonus.

Stainless steel flange pipe welding, carbide separation by repeated heating, thereby reducing corrosion resistance and mechanical properties, prevent the covering on the sticky oil dirt, prevent increase weld carbon content, influence the welding quality, to prevent corrosion due to flange cover heating, shoulds not be too big welding current, arc shoulds not be too long, the interlining should rapidly cooling, initiative to use narrow weld. In order to improve the corrosion resistance and weldability, stainless steel flange is properly added some unchanged elements, its weldability is better than chrome stainless steel flange, if the welding parts can not stop the hot disposal, should choose stainless steel flange electrode, stainless steel flange fittings have excellent corrosion resistance and oxidation resistance, suitable for welding flange electrode.
Stainless steel flange gaskets should have good aging resistance and oil resistance, as well as good mechanical strength and elasticity, should be based on the shape of the joint to choose different sections and sizes of gaskets, and correctly placed. Stainless steel flange rubber ring requests to be placed in any direction of the concave and convex groove, the big head inward, should check whether there is deformation of the device ignored.
Different steel structures can cooperate with mold and mold powder vibration process, so as to complete the injection of stainless steel pipe fittings, stainless steel flange should have enough strength, in the process of tightening should not be deformed, stainless steel flange sealing surface should be smooth and clean, the device should be carefully cleared oil and rust spots.
