Flange bolts
And nut with flange bolts: hex head and split flanges (gasket with hex hexagon below are fixed together) and screw (cylinder with an external thread) two-part fasteners for fastening connecting the two parts with a hole.
This form of connection, said bolts. To unscrew the nut from the bolt, so that the two parts separately, so bolted
Then are detachable connection.
1, hex flange type: hex head, there are two, one is the level of the brain, the other is concave brain.
2, the surface color categories: according to different needs, surface plated white, green, yellow color, another never DACROMET rusty.
3, the flange categories: according to the type of the location of use of the flange bolts, the size requirements for rent of the same, otherwise flat and toothed stars, since the toothed anti-slip effect.
4, according to the connection force, ordinary and articulation hole. Articulation hole flange bolts with and the size of the hole in the lateral force.
In addition, in order to meet the need for locking after installation, the rod holes, these holes can make the vibration on the bolts to come loose.
Some flange bolts not threaded rod light painstaking, called thin rod flange hydraulic bolt. flange bolts conducive inotropic join.
Steel structure dedicated high strength bolts. Bigger head size change.
Flange and pipe intimate fusion
Flange manufacturers, and pipeline welding, its form, there are two, one is socket welding, another butt welding.
Socket weld fillet welds, welding through the pipe into the hydraulic flanges, reinforcing the role of the socket. Mainly used for small diameter valves and pipes, pipe fittings and pipe welding. Because of the small diameter pipeline butt is difficult, because it is thinner wall thickness, it is prone to the wrong side and ablation. The socket welding can not be ray detection using magnetic particle or penetrant testing testing. However, post-weld stress is not good penetration welding, leaving a gap inside the pipes. Sensitive to crevice corrosion, cleanliness pipes, small diameter pipeline wall thickness, weld testing requirements, do not use the socket weld.
Butt with welded flange, butt weld. Welding quality is good, with ray testing, more stringent because the detection of the welded split flanges. Flange elbow can be welded to the large wall thickness of the pipe of small diameter; welded flange high cleanliness, corrosion resistant, and can be applied to the crevice corrosion sensitive medium pipe system and pipes with high cleanliness requirements. Butt strength and force must be better than the socket welding, suitable for high pressure levels, use of harsh environment.
Stainless steel flanges
The stainless steel flange is a disk-shaped parts, the most common in the pipeline project, the flanges are used in pairs. In the pipeline project, the flange is mainly used for the connection of the pipeline. Need to connect pipes, various mounting a flange, low-pressure pipe can be used silk flange, the use of more than 4 kg pressure welding flanges. Plus seal between the two flanges, and then secured with bolts. The different pressures flange have different thickness and the use of different bolts.
Pumps and valves, and pipe connections, facilities and equipment of the local, but also made a corresponding flange shape, also called a flange connection. All in two planes used in the surrounding bolted closed simultaneously connected parts, generally known as the "flange", such as ventilation pipe connections, this type of parts can be called a "flange parts. But this connection is only local device, such as flange connections and pumps, it is not good to pump called the "flange parts. Relatively small, such as valves, can be called "flange parts.
The gasket is able to produce plastic deformation, and having a certain intensity of the material of the ring. Most of the gasket is cut down from the non-metallic plate size produced by professional factory in accordance with the regulations, the material is asbestos rubber sheet, asbestos sheet, polyethylene sheet; asbestos also useful for thin metal plates (white iron, stainless steel) wrapped package gaskets made of metal and other non-metallic materials; There are spiral wound gasket with wound together by a thin strip asbestos. Applicable to ordinary rubber gasket occasions at a temperature below 120 ° C; asbestos rubber gasket suitable for the steam temperature is lower than 450 ° C, the oil temperature is lower than 350 ° C, pressure less than 5MPa occasions for general corrosion medium, most commonly used are acid-resistant asbestos board. Copper, aluminum, steel, stainless steel (No. 10) in the high-pressure equipment and piping, lens type, or other shapes of metal shim. The high-pressure gasket and the sealing surface of the contact width is very narrow (line contact), the sealing surface and the processing of the gasket finish higher.
Low voltage small diameter wire connected to the hydraulic flanges, the high and low pressure large diameter are used the weld flange, the thickness of the flange and the connection of the bolt diameter and number of the different pressures is different.
Flange interface
The flange is a disk-shaped parts, the most common in the pipeline project. The edge flange bolt connection can be used for machine structure, such as a pipe butt, on the interface with a stainless steel flange can be connected with bolts, and the cover flange, the edge of the cover has a flange edge, can be fixed with bolts. Flanges are used in pairs. In the pipeline project, the flange is mainly used for the connection of the pipeline. Need to connect pipes, various mounting a flange, low-pressure pipe can be used silk flange, the use of more than 4 kg pressure welding flanges. Plus sealing point between the two flanges, and then secured with bolts. The different pressures flange have different thickness and the use of different bolts. Pumps and valves, and pipe connections, facilities and equipment of the local, but also made a corresponding split flanges shape, also called a flange connection. All in two planes used in the surrounding bolted closed simultaneously connected parts, generally known as the "flange", such as ventilation pipe connections, this type of parts can be called a "flange parts. But this connection is only local device, such as flange connections and pumps, it is not good to pump called the "flange parts. Relatively small, such as valves, can be called "flange parts.
