Steel expansion joint introduction：

The steel expansion device produced by Gongyi Zhongyuan innovation pipeline Equipment Co., Ltd. is composed of loose sleeve and a flange limit short pipe, it can prevent the pipeline due to excessive displacement caused by compensation joint leakage and damage, steel expansion device is mainly used in the allowable displacement range to absorb the axial displacement and withstand the axial pressure thrust pipe loose sleeve connection. ZhongYuan are always mindful that all energy comes from the CUSTOMER, Zhongyuan valve fittings Reminder Norway Friends can refer to these knowledge: Before the installation of the steel telescopic device, the pressure plate bolt must be loosened, the product is pulled to the installation length, and then tightened with the diagonal method, the iron cutting pressure deviation, such as overhead use, both ends must be installed with the corresponding firm support; The steel telescopic device provides great convenience for the arrangement and replacement of various water supply and drainage pipes, water towers, pumps and valves, and plays a good regulating role for the expansion of long-distance pipelines due to temperature difference; Key points of product knowledge in the field of metallurgy: Before placement, the pressure plate bolt must be loosened, the steel telescopic device is pulled to the placement length, and then tightened diagonally to cut the iron pressure deviation, such as overhead use, both ends must be placed with the corresponding firm support; French connection accepts GB/T9112-9124-2000 scale (material Q235); If you choose other specifications can be produced separately.

Steel expansion joint advantage：

Steel expansion joint is suitable for connecting both sides with flanges. Adjust the connection length between both ends of the product and flanges when installing Steel expansion joint. Change for a better future, Zhongyuan valve fittings reminds Norway friends that this information is helpful for choosing Chinese products: Tighten the gland bolts evenly diagonally and then adjust the limit nuts. In this way, the Steel expansion joint enables the pipeline to expand freely within the scope of expansion volume, locking expansion volume and ensuring the operation of the pipeline.

Steel expansion joint feature：

1. Compensation absorption pipeline axial, transverse, angular thermal deformation.

2. Absorb equipment vibration to reduce the impact of equipment vibration on pipelines.

3. Absorb the deformation of the pipeline caused by earthquake and subsidence.
