Description

Stainless steel lining tetrafluoro compensator

Technical Field

The utility model relates to a stainless steel inside lining technical field especially relates to stainless steel inside lining tetrafluoro compensator.

Background

Stainless steel is short for stainless acid-resistant steel, and steel grade which is resistant to weak corrosive media such as air, steam and water or has stainless property is called stainless steel; and steel grades that are resistant to corrosion by chemically corrosive media (chemical attacks such as acids, bases, salts, etc.) are called acid-resistant steels. Because of the difference in chemical composition between the two, the corrosion resistance of the two is different, and common stainless steel is generally not resistant to corrosion of chemical media, while acid-resistant steel is generally stainless. The term "stainless steel" refers not only to a single type of stainless steel, but also to more than a hundred types of industrial stainless steels, each of which has been developed to have good properties in its particular application field. The key to success is first to figure out the application and then to determine the correct steel grade. There are generally only six steel grades relevant to the field of building construction applications. They all contain 17-22% chromium, the preferred steel grade also contains nickel. The addition of molybdenum further improves atmospheric corrosion, particularly corrosion resistance to chloride-containing atmospheres. The PTFE compensator is an industrial instrument, is called as PTFE corrugated pipe compensator (also called as expansion joint), and is used for compensating the displacement and installation deviation of expansion with heat and contraction with cold in a pipeline system of strong corrosive medium, thereby reducing the vibration of the pipeline system. When a medium in a pipeline system flows back, a transient vacuum state is formed in the tetrafluoro compensator, and the tetrafluoro compensator has good pressure resistance, so the tetrafluoro compensator is often used in equipment such as vacuum-resistant and high-temperature-resistant tower sections, reaction kettles and the like.

The existing flange and corrugated pipe integrated structure on the market at present is difficult to detach the flange, and when the corrugated pipe is damaged, the whole tetrafluoro compensator needs to be replaced, so that higher maintenance cost is caused, and the problem is solved. To this end, we propose a stainless steel lined tetrafluoro compensator.
