In fact, a performance by the corrugated compensation may be caused by: molding machine welding residual stress generated or produced within the operating pressure and weight of a film stress of expansion joints, addition is secondary stress generated by thermal expansion, and pipe vibration, However, due to the presence of stress under single flange expansion joints, making the bellows is in elastic-plastic working condition; alternating stress temperature, and internal pressure fluctuations caused by the engine off, the last is the installation error and variations caused by assembling pre-stress , compensator peaks and valleys withstand great tensile stress is generated SCC provides a tensile stress conditions conduit loose telescopic joint, as a result causes distortion of the crystal lattice of the metal, reduces the electrode potential of the portion, in that the smoke When the gas medium (electrolyte solution) contact, these areas become corrosive micro-battery anode, and cause localized corrosion, with increased corrosion, crack rapid expansion until the product damage. So when we hit the water shock wave pattern compensation phenomenon, we can solve ductile expansion joints up from the bracket and install the valve bellows pipe, because most of the water hammer phenomenon occurs is that in these places, and we To prevent corrugated compensator water hammer phenomenon in the face of it, we usually have to do the bellows and the bellows sleeve diversion maintenance and protection work, so will be able to reduce the bellows in encounters water hammer phenomenon when damaged. The price of steel expansion joint expansion joints _ _ supply materials provided by Serco Serco Gongyi City Water Supply Materials Co., Ltd. Serco Gongyi City Water Supply Materials Co., Ltd.
