Products produced metal hose production technology continuous molding a single wave (a) of the mold, at two symmetrical push mode! And die 'while moving vertically parallel to the axis of the tube blank, will be installed on the spindle # The thin-walled tube blank $ tightly wrap from the outer surface. (B) into the spindle core sleeve seals% and pipe billet overcome the frictional resistance of the inner wall, move to the left, so that the seal is fixed on the mandrel and die relative motion to the position it is set in advance. (C) the filling pressure of the liquid working fluid flows dedicated metal hose mandrel between the two seals from the center hole, the inner wall of the tube blank work. Under the influence of fluid pressure, the tube blank between two ring projections, forming the beginning of the wave. (Iv) into the push mode to push against the spring & mold resistance along the guide slider 'move to the right, so that the original early wave height increases, the width of the narrow, until the design size up how to select materials for large-diameter metal hose it? In recent years, special metal hose is durable, with metal hose application market is growing, while the technology also has high requirements for large-diameter metal hose and friends when in use always hesitated , so much the cost will be high caliber itself, if the use of 304 or better material 316 316L special metal hose prices, is it on the higher cost of it? For DN200 than the inner diameter of the corrugated metal hose, tube that is inside the bellows must be used even more than 304 dedicated professional custom material metal hose, 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, oil or air will have its performance, anti-rust, anti-corrosion, high temperature, etc., is a stainless steel mesh cover, this layer can be ordinary stainless steel 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 according to customer usage flange can be carbon and stainless steel, big diameter stainless steel metal hose majority of users will have to get regular factory responsible for production, to ensure the quality and use. Special metal hose the best quality, Hopen hose, metal hose is provided by dedicated Ning County Hopen stainless steel metal hose Limited.
