Double flange Transmission expansion joints Serco supply price _ _ expansion joint material provided by Serco Gongyi City Water Supply Materials Co., Ltd. Serco Gongyi City Water Supply Materials Co., Ltd. (www.gyxjbcq.com/) is specialized in the "PTFE lined rubber joints, standard waterproof casing, duckbill valve, power connector, stainless steel, rubber joints" of the enterprise, the company adhering to the "integrity management, service intentions, "the idea, to provide you with the highest quality products and services. Welcome to inquire! Contact: Zhang. Installation requirements: (1) compensation at both ends of the pipe wall thickness welded ≥6mm, must be treated groove after welding pressure leak test as required. (2) Slide the bracket and mounting bracket in accordance with design, installation, use ZTWB type, in addition to the working pressure of the media is not calculated thrust, the other the same. To ensure that no lateral displacement of the pipeline, while the axial expansion, compensation should normally be installed at both ends of the guide and slide the bracket bend in the pipe, you must install the mounting bracket. Thermal protective structure (3) corrugated pipe compensator are going the same way, but part of the telescoping tube telescopic double flange limited telescopic joint manufacturers, can not be binding. (4) The compensation under various environmental temperatures, can be installed according to the maximum length LMax to install, no be stretched or compressed. In fact, a performance by the corrugated compensation may be caused by: molding machine welding residual stress generated, or the working pressure and stress caused by the weight of the first film, addition is secondary stress generated by thermal expansion, and pipe vibration, temperature, pressure fluctuations inside and off on alternating stress caused by installation errors and the last is a pre-assembled stress variations caused; but because of the presence of stress, making the bellows is in working condition under the elastic-plastic, compensator peaks and valleys bear it tensile stress, for SCC generates tensile stress conditions provided expansion joints, the result is caused by lattice distortion of the metal, reduces the electrode potential of the portion of the demolished double flange limited telescopic joint, in that the flue gas medium ( When the electrolyte solution) contact double flange limited telescopic joint price, these parts become corrosive micro-battery anode, and cause localized corrosion, with increased corrosion, crack rapid expansion until the product damage.
