Sleeve-type expansion joints series

I produced the sleeve-type expansion joints for town water tower, pumping stations, water meters and valves installed removable to provide a great convenience, as well as long-distance pipeline due to scale problems caused by temperature difference, played a good role to fill, instead of the U-tube. This product can be used for water supply and drainage engineering, thermal engineering for the general temperature by 250 ℃, pressure by 1.6Mpa factory. At the same time according to user needs and have a special parameter range of products to meet the gas, petroleum, chemical, water, electricity and other fields, their connections are: double disc, insert the disc, the disc bearing; flange dimensions according to existing national standards, according to user requirements plus anti-pull-off limit bolts. Installation Notes: 1, the installation should be between the maximum and minimum length, can be adjusted according to the actual situation. 2, installation, loosen the bolts packing platen, adjust installation length, and both ends of the tube (or valve, water) is installed according to design requirements, and then check the packing is properly seated, and finally the pressure on the packing pressure plate, with a diagonal method partial pressure not to tighten the bolts to stanch role to play. 3, expansion joints installed after the check valve. 4, expansion joints must be set buttress ends, which itself does not bear axial tension, necessary, to add anti-pull-off.
