JIS 2220 flange is widely used in machinery, so the appearance is also very strange, just like is called flange, so the flange is a kind of disc parts, are the most common in the pipeline engineering, the flange is used in pairs.In pipeline engineering, the flange is mainly used for pipe connection.Different stress of flange bolts with different thickness and use different.Pump and valve and pipeline connection, these local equipment, also made the corresponding shape of Japanese standard flange, also known as flange connection.
Carbon steel flange installation considerations to understand it, the first thing to check is the pipes, pipe fittings and aprons.Whether is qualified and can face clean seal in the socket and the pipe air buy 20 minutes can achieve the best sealing glue.To achieve the best results, aprons pore and fracture, time is too long or too short shall be a conducive to people's optimization and experience, set up a good pipe damage maintenance system is necessary.
Carbon steel flange aprons and provisions in any direction and took a big head, placed in undertaking the concave and convex chamfer, shall not be distorted neglect to review the installation, outcome and the word of mouth, must want to undertake after refining of molten steel ladle, with verification to the top of the sprue, water will be injected into the tundish.Screw fixation of the surface of the second cold forging to get fast training purpose, this is flame cutting form, reach the root of the whole process is different.
The vibration of the steel structure can do different mould technology and matching between protecting slag, thus realizes the stainless steel pipe fittings injection, basic don't repair the surface of the state, the goal and steadily advance, will get the system to improve the small water conservancy projects, enhance the vitality of grass-roots water conservancy development, guide around the small water conservancy reform, actively guide to promote the standard of peasants' water.
