Stainless Steel BL Flange Suppliers and Manufacturers brief introduction.
STAINLESS STEEL BL 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. Also known as stainless steel blind flange, real name blind plate. Is a form of connection of the flange. In fact, there is no hole in the middle of the flange.The following is the stainless steel bl flange, the relevant pressure, the various parts of the size and icon,

Stainless Steel BL Flanges Features
One of the features of the stainless steel bl ind flange is to block the end of the pipe, and the other is to have the ability to easily remove the debris from the pipe during maintenance.
In the case of plugging, with the head and cap have the same effect. But the head is no way to disassemble, and the flange blind plate is fixed with bolts, it is easy to disassemble.
Flange blind plate material is carbon steel, alloy steel, stainless steel, plastic and so on
Stainless Steel BL 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 wn flange pipe welding, by repeated heating precipitation of carbides, reducing corrosion resistance and mechanical properties.
4, chrome stainless steel wn 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 wn 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 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.
