How to select the material for large-diameter metal hose it? In recent years, with the metal hose application market is growing, while the technology also has high requirements for large-diameter metal hose, my friends always hesitated when in use, and the cost of such a large-diameter itself It will be high, if the use of 304 or better material 316 316L, would not cost even higher yet? For DN200 than the inner diameter of the corrugated metal hose, tube that is inside the bellows professional management of industrial metal hose must be used even more than 304 materials, first of all no matter where the user is in the product, the level of direct contact with the through the media, whether through the medium is water, steam hose retail price of industrial metals, oil or air will have its performance, anti-rust, anti-corrosion, high temperature, etc., is a set of stainless steel wire mesh industrial metal hose, this layer with ordinary stainless steel can, under the pressure of the situation is that the two sets of steel netting steel goods, the largest model did 800 caliber, advanced equipment and complete testing equipment based on the use of customers case flange can be carbon and stainless steel, large diameter stainless steel hose majority of users will have to get regular factory responsible for production, to ensure the quality and use. Why metal hose will be broken? Metal hose stainless steel mesh cover mainly protective bellows and bellows to withstand internal pressure media (mainly axial force). Nets covering the outside of the bellows, the bellows ends and the end ring and joint welding. (1) Weld cause screen sets to pull off because of the quality of welding, the bellows, ring and steel wire mesh sleeve Weld in part caused by the welding process Trinity (over-burning or welding on the end). After this hose into the pipe due to the wire uneven force, at medium pressure, Weld pulled off at the wire first industrial metal hose industry preferred, the entire steel mesh sleeve to pull off, resulting in failure of the bellows outer drum , dangerous. To put an end to this situation, should improve the welding quality, water pressure and leak test should be carried out before the assessment hose factory, after passing to the factory. (2) improper installation, causing the screen to pull off the industrial metal hose manufacturers, wholesale, Hopen hose, metal hose industry by Hao Peng Ning County, stainless steel metal hose Limited.
