Titanium flange

Current location: Home > Titanium flange >
 

The flange is also called flange or flange. A flange is a part that connects a pipe to a pipe, and is connected to a pipe end. There are holes in the flange, and bolts make the two flanges tight. The flanges are sealed with a gasket. Flange sub-threaded (wired) flanges and welded flanges.
effect:
1. Connect the pipeline and maintain the pipeline sealing performance;
2, to facilitate the replacement of a certain section of the pipeline;
3, easy to open inspection pipeline situation;
4, to facilitate the closure of a section of the pipeline.
Precautions:
1. In order to prevent the eye-catching corrosion caused by the heating of the flange cover, the welding current should not be too large, about 20% less than the carbon steel electrode, the arc should not be too long, the inter-layer fast cooling, narrow pass bead is appropriate.
2. When the electrode is used, it should be kept dry. The titanium-calcium type should be dried at 150°C for 1 hour. The low-a hydrogen form should be dried at 200-250°C for 1 hour (can not be repeated for many times, otherwise the coating will be easily cracked and peeled). The electrode sticks stick oil and other dirt so as not to increase the carbon content of the weld and affect the quality of the weldment.
3, stainless steel flange pipe welding, subject to repeated heating precipitation of carbides, reducing corrosion resistance and mechanical properties.
