The basic structure of the axial type metal bellows axial bellows is widely used to absorb axial displacement compensation, mainly for straight pipe displacement compensation, of course, can also absorb a small amount of lateral displacement. Mainly because of corrugated metal hose by bellows, so there are a lot of different places, it is called. Its structure is varied, but basically similar device due to the composition of the two adjacent pipes, flanges and other devices or a metal bellows, generally depending on the circumstances have to be equipped with different sets of diversion or sleeve, etc. use. Hinged metal bellows is mainly used in the displacement of the plane does not have the axial pipe factory direct performance of corrugated metal hose is generally plus or minus 9 degrees of compensation. Specific parameters are as follows: Specifications: DN65-DN5000 Pressure: 0.1MPA-2.5MPA connection: a flange connection 2. takeover compensation:. ± 4 ° - ± 9 ° axial bellows mainly because absorb lateral displacement limited capacity and can not be used in more than a certain pressure or temperature, the diameter is too big occasions, and the case of axial and lateral displacement or lateral displacement of the occasion may not be able to use the existence, then we should choose another bellows instead a. Why stainless steel corrugated metal pipe rust rusty metal bellows why it? We are very confused, in fact, wholesale corrugated metal hose, the main material of stainless steel metal bellows 304 is the US standard called gas stainless steel corrugated metal hose, also called SUS304, cr18ni9 is its chemical formula. Stainless steel is an alloy element causing the oxide film formed, cut off from contact with oxygen, in order to make rust. Of course, users will find the situation in the use of stainless steel metal bellows rusty, this is a normal phenomenon. For example, the presence of chloride ions in the environment of use, due to the widespread presence of chloride ions in the water, soil and other environments, it will accelerate rust. Therefore, in these cases the use of words should pay special attention to dust, to keep clean. There are several cases without a solid financial and other treatment that will result in a low alloy content, corrosion resistance decreased. 304 stainless steel bellows because no titanium elements among its poor intergranular corrosion. Stainless steel is a good corrosion resistant alloys in the air, its surface treatment is not necessary, will be able to play its due performance, with a representative of the 316 316L stainless steel. From the other point of view, because it will be in stainless steel containing chromium thin layer formed on the surface film, precisely because this layer contains the film in order to use stainless steel bellows eternal luster. Stainless steel bellows must have more than 2% of chromium in order to make it not rust, but some manufacturers cut corners to reduce costs. Since 304 is a general purpose material, it is widely used in industry and other good overall performance requirements of the device.
