There are three types of Carbon Steel Flange sealing surface: flat type sealing surface, suitable for the pressure is not high, the media non-toxic occasions; convex sealing surface, for a slightly higher pressure occasions; tongue seal surface, for flammable, explosive , Toxic media and high pressure occasions.
A gasket is a ring made of a material that produces plastic deformation and has a certain strength. Most of the gaskets are cut from non-metallic plates or made of professional factories in the specified size, the material for the asbestos rubber sheet, asbestos board, polyethylene plate, etc .; also useful thin metal plate (white metal, stainless steel) asbestos And other non-metallic materials wrapped together made of metal gasket; there is a thin steel belt with the asbestos wound with a wound wound gasket. Ordinary rubber gasket for the temperature below 120 ℃ occasions; asbestos rubber gasket is suitable for water vapor temperature below 450 ℃, the oil temperature below 350 ℃, the pressure is less than 5MPa of the occasion, for the general corrosive Medium, the most commonly used is acid asbestos board. In high pressure equipment and pipes, the use of copper, aluminum, 10 steel, stainless steel made of lens or other shape of the metal gasket. High-pressure gasket and sealing surface contact width is very narrow (line contact), sealing surface and gasket processing high finish.
1. Material to divide carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, argon Ge Lek, ppc and so on.
The following are the same as the "
2. The production method can be divided into push, suppression, forging, casting and so on.
The following are the same as the "
3. To the manufacturing standard can be divided into national standard, electric standard, water standard, American standard, German standard, Japanese standard, Russian standard and so on.
4. According to the connection type Carbon Steel Flange connection type can be divided into:
Plate flat welding Carbon Steel Flange, with neck flat welding Carbon Steel Flange, with neck welded Carbon Steel Flange, socket welding Carbon Steel Flange, threaded Carbon Steel Flange, Carbon Steel Flange cover, with neck welding ring loose Carbon Steel Flange, flat welding ring loose sets of law Blue, ring groove Carbon Steel Flange and Carbon Steel Flange cover, large diameter flat Carbon Steel Flange, large diameter high neck Carbon Steel Flange, character blind plate, butt welding ring loose Carbon Steel Flange
Carbon Steel Flange connection is to put two pipes, fittings or equipment, first fixed on a Carbon Steel Flange, between the two Carbon Steel Flanges, plus a Carbon Steel Flange pad, bolted together to complete the connection The Some fittings and equipment have their own Carbon Steel Flanges, but also belong to the Carbon Steel Flange connection. Carbon Steel Flange connection is an important way to connect pipe construction.
Carbon Steel Flange connection easy to use, able to withstand greater pressure. In industrial piping, the use of Carbon Steel Flange connections is very extensive. In the family, the pipe diameter is small, and is low, can not see the Carbon Steel Flange connection. If in a boiler room or production site, full of Carbon Steel Flanged pipes and equipment.
Carbon Steel Flange also known as Carbon Steel Flange or Carbon Steel Flange. A Carbon Steel Flange is a part that connects a pipe to a pipe and is connected to a pipe end. There are holes on the Carbon Steel Flange, the bolts make the two Carbon Steel Flanges tight. The Carbon Steel Flange is sealed with a gasket. Carbon Steel Flange thread connection (wire) Carbon Steel Flange and welding Carbon Steel Flange. Carbon Steel Flange Carbon Steel Flange also known as Carbon Steel Flange or Carbon Steel Flange. Is the pipe and pipe interconnected parts. Connected to the pipe end. Carbon Steel Flange on the hole, can wear bolts, so that two Carbon Steel Flanges tight. The Carbon Steel Flange is sealed with a gasket. A pipe fitting with a Carbon Steel Flange (Carbon Steel Flange or plate). It can be made of cast, but also by thread connection or welding composition. The Carbon Steel Flange connection consists of a pair of Carbon Steel Flanges, a gasket and a number of bolts and nuts. Gasket on the Carbon Steel Flange between the two sealing, tighten the nut, the gasket on the surface of the specific pressure to a certain value after the deformation, and fill the sealing surface on the uneven, so that the connection is tightly leaked. Some fittings and equipment have their own Carbon Steel Flanges, but also belong to the Carbon Steel Flange connection. Carbon Steel Flange connection is an important way to connect pipe construction. Carbon Steel Flange connection easy to use, able to withstand greater pressure. In industrial piping, the use of Carbon Steel Flange connections is very extensive. In the family, the pipe diameter is small, and is low, can not see the Carbon Steel Flange connection. If in a boiler room or production site, full of Carbon Steel Flanged pipes and equipment. Popularly speaking, the role of the Carbon Steel Flange is to make the pipe joints fixed and sealed.
Use Notes 1, in order to prevent the lid due to heating and produce 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, narrow bead is appropriate The 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 Carbon Steel Flange pipe welding, by repeated heating precipitation of carbides, reducing corrosion resistance and mechanical properties. 4, chrome stainless steel Carbon Steel Flanges after welding hardening American standard Carbon Steel 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 Carbon Steel Flange fittings electrode (A107, A207). 5, stainless steel Carbon Steel 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 Carbon Steel Flange better. When using the same type of chromium stainless steel Carbon 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 Carbon Steel Flange fittings (A107, A207). 6, stainless steel Carbon Steel Flange fittings, butt welding Carbon Steel Flange has good corrosion resistance and oxidation resistance, widely used in chemical, fertilizer, oil, medical machinery manufacturing.
