Problems using gaskets in deacidification and deodorization towers
Thread Content
This post was last edited by chenxchuan541 on 2017-3-17 16:31 for help. The existing deacidification and deodorization tower has a vacuum degree of -0.1mpa and an operating temperature of 230 degrees. How should I choose a gasket? ? ? Since it is a grease food industry, asbestos rubber sheets are prohibited. In addition, when checking the information, I found that the information on polytetrafluoroethylene gaskets is different, so I asked an expert to tell me. Attached pictures
The temperature is 230 degrees. It is best to use spiral wound gaskets. The temperature resistance of PTFE gaskets generally does not exceed 150 degrees.
Why is it necessary to use flange protective covers and valve protective sleeves? Why use anti-splash protection devices? Safety anti-splash devices are safe for personnel, equipment and the environment. In the enterprise production system, there are a large number of pipelines transporting liquid hazardous chemicals. The liquid hazardous chemicals are highly corrosive. Due to thermal expansion, contraction, aging and other reasons, the flange gasket forms a leak point and liquid splashes. The flange protective sleeve is a safety protection product that can effectively prevent hazardous liquids from leaking and injuring people, and can slow down the corrosion rate of flanges. The flange protective cover is mainly used to prevent liquid splashing and leakage caused by loose flange connections or excessive pipeline pressure during the connection process, and plays a very good protective role in causing damage to on-site workers and surrounding equipment. Safety first, prevention first. Don’t wait until an accident occurs before checking. Safety protection should be strengthened, especially in management, and effective protective measures should be taken. Most of the media transported by flange-connected pipelines are highly corrosive substances with high temperature and high pressure. Due to the loose connection of the flange during the connection process or excessive pipeline pressure, liquid splashes and leaks can easily cause damage to on-site workers and surrounding equipment. The function of the flange protective cover is to provide good protection against these accidental injuries. Therefore, more and more manufacturing companies are now aware of the importance of prevention and take precautions to nip problems in the bud.
