Stainless Steel Flange, also know as stainless Steel Pipe Flange, which are used to connect pipes. It can be divided as threaded flanges and welding flanges.
Flange is a disk-shaped parts, the most common in the pipeline project, flanges are paired and the mating flange on the valve used. In the pipeline project, flanges used to connect pipes. The need to connect pipes, various mounting a flange, low-pressure pipe can be used silk flange, the use of four kilograms or more pressure welding flanges. Between the two flange gaskets, then bolted. Different pressures flange have different thickness and different use of bolts.
Pumps and valves, and when the pipe connections, these local facilities and equipment, also made the corresponding flange shape, also known as the flange connection. All in two planes at the same time surrounding the use of bolted closed parts, generally known as the [flange", such as ventilation pipe connections, this type of parts can be called [flange parts." But this is only a partial connection device, such as flange connections and pumps, on the bad pumps called [flange parts." Relatively small, such as valves, etc., can be called [flange parts."
A gasket capable of plastic deformation, and has a certain strength of the ring material. Most non-metallic gaskets are cut from the plate down, according to the factory or by a professional sized, the material is asbestos rubber sheet, asbestos, polyethylene panels; also useful for sheet metal (tin, stainless steel) asbestos other non-metallic materials wrapped package gasket made of metal;
There is also a strip along winding made of spiral wound gasket with a thin strip of asbestos. Common rubber gasket suitable for temperatures below 120 ℃ of occasions; asbestos rubber gasket suitable for steam temperature is lower than 450 ℃, the temperature of the oil is lower than 350 ℃, a pressure less than 5MPa occasion, general corrosion medium, most commonly used acid asbestos. In the high-pressure equipment and piping, copper, aluminum, steel on the 10th, the lens type or other shaped metal gasket made of stainless steel. Contact width high pressure gasket sealing surface is very narrow (line contact), the gasket sealing surface and high finish machining.
Low voltage small diameter wire flange, high and low pressure large diameter are using welding flange thickness and bolt diameter and number of connecting different pressures flange is different.
- connecting pipe and holding pipe sealing performance;
- to replace certain pipeline;
- to open and inspect the pipe line;
- to facilitate the closure of certain pipeline.
