Stainless Steel SO Flange SUPPLIERS AND MANUFACTURERS BRIEF INTRODUCTION.
Stainless Steel SO Flange Belong to the American standard flange standard system. Is the American standard flange (also known as ANSI flange) one of the manifestations of equipment or pipes commonly used in the flange. The following is the ANSI SO FLANGE, the relevant pressure, the various parts of the size and icon,

Stainless Steel SO FlangeS Features
Stainless steel so flange is also called loose flange
stainless steel so flange is the use of flanging, steel ring and so on the flange set in the pipe end, the flange can be in the tube end activities. Steel ring or flanging is the sealing surface, the role of the flange is to press them.
It can be seen because the steel ring or flanging block, loose flange is not in contact with the media.
Sliding flange for steel, aluminum and other non-ferrous metals and stainless steel acid-resistant steel containers connected and corrosion-resistant pipeline.
stainless steel so flange is the activities of the flange, the general is supporting the water supply and drainage accessories (the most common on the expansion joints), manufacturers at the end of the expansion and contraction of the two ends have a flange, directly with the pipeline in the project, equipment Connect with bolts.
Is the kind of flange with lapel.
Generally used in the pipeline, so, loose bolt can rotate the pipe on both sides, and then tighten. Can be more convenient to disassemble the pipeline. Loose flanges are also called loose sets of flanges.n.
Flange connection is an important way to connect the construction of the pipeline.
Flange connection easy to use, able to withstand greater pressure. In industrial piping, the use of flange connections is very extensive.
In the family, the pipe diameter is small, and is low, can not see the flange connection. If in a boiler room or production site, full of flanged pipes and equipment.
Stainless Steel SO Flange Precautions for use:
1, in order to prevent the heating caused by the flange cover between the eye corrosion, welding current should not be too much,
less than about 20% of carbon steel electrode, arc should not be too long, cold between the layers to narrow the weld is appropriate.
2, the electrode should be used to dry, titanium calcium type should be dried at 150 ℃ for 1 hour, low a hydrogen type should be 200-250 ℃ drying 1 hour
(can not be repeated drying, or easy to peel the skin peel), to prevent Welding paste oil and other dirt, so as not to cause the weld to increase the carbon content and affect the quality of welding.
3, stainless steel so flange pipe welding, by repeated heating precipitation of carbides, reducing corrosion resistance and mechanical properties.
4, chrome stainless steel so flanges after welding hardening American standard flange larger, prone to crack.
If the same type of chromium stainless steel electrode (G202, G207) welding, must be more than 300 ℃ preheating and 700 ℃
after the slow cooling treatment. If the weldment can not be post-weld heat treatment, you should use stainless steel flange fittings electrode (A107, A207).
5, Stainless Steel SO Flange, in order to improve the corrosion resistance and weldability and the appropriate increase in the amount of stability elements Ti, Nb, Mo,
welding better than chromium stainless steel so flange better. When using the same type of chromium stainless steel flange electrode (G302, G307), should be more than
200 ℃ preheat and 800 ℃ after tempering around the tempering treatment. If the weldment can not be heat treated, you should use stainless steel flange fittings (A107, A207).
6, stainless steel flange fittings, butt welding flange has good corrosion resistance and oxidation resistance, widely used in chemical, fertilizer, oil, medical machinery manufacturing.
