Supply Hao Bo Duobo single-wave two-wave four large corrugated board box type can limit expansion compensator great ..

1 Introduction Large corrugated board box compensation from the flange, draft tube, metal wave body take over accessories. It belongs to a compensator. Using their body of work stretching deformation effective bellows to absorb pipe axial, lateral, angular thermal deformation, but also facilitate the installation and removal of the pipe can also absorb earthquake, subsidence impact of the pipeline. In modern plumbing the more commonly used. 2 Benefits board box type can limit pipeline compensator is an important part pipe installation, the compensator has a small size, easy installation, small footprint, reduce labor intensity, labor, labor, material saving, practical and other advantages. Telescopic amount 60-120mm, no seepage, no leakage, no filler, flexibility is good, safe and reliable, and can save maintenance work, do not set well when installed expansion force, reduce the project cost, the compensator novel structure, reasonable no wearing parts, small size, light weight, easy installation and transportation, is the ideal product pipeline installation. 3 design and construction requirements 1, the product uses pressure 1.6MPa or less, use the medium: hot water, steam, gas, the same variety of oil, temperature and piping, high-rise buildings using the best; 2, the product maximum thrust of 0.8 to 1.2 T, use fatigue life 6500; 3, the product can be widely used overhead pipes, waste pipes, buried pipe; 4, compensation can be set from time to set up the steering support; 5, the product to install and use only the axial (linear pipeline ); 6, do not build the product pipeline compensation when used in cooking well; 7, the installation of ignition is prohibited on the compensator telescopic boxes; 8, the product of the second wave to pull 25mm-30mm, four-wave to pull 50mm-60mm ; 9, proved in hot water heating pipe line, 60m should be located above a two-wave expansion joints, should be located 120 meters above a four-wave expansion joints, steam piping design criteria should be installed within 30m stretch a two-wave.
