Matters needing attention when installing the pipe support and hanger
(1) When installing the pipe support and hanger, it should be straight and firm, and the welding should be operated by a full-time welder.
(2) Beams should be placed on both sides of the groove wall thickness of not less than 1/2, to avoid deflection or falling off.
(3) Steel plates should be pre-embedded on the concrete (or brick) pier surface to prepare for the sliding of the sliding support, and the sliding support should not slide directly on the top surface of the concrete to increase the frictional resistance.
(4) The sliding bracket and the pipe are welded with flowers, and spot welding is not allowed to avoid the sliding bracket falling off.
(5) When the spacing of movable supports is clearly marked in the construction drawing, construction should be carried out according to the drawing, but when hanging supports are used, hangers should be added at the valve or pipe fittings to avoid deformation of the pipeline due to uneven load distribution.
(6) The height of the pipe support should consider the clear distance between the pipe ditch bottom and the ditch cover after the pipeline is installed, that is, to ensure that the pipeline insulation layer is not soaked in water and crushed by the ditch cover, and the distance for maintenance should also be considered.
(7) It is required that the installation of the pipeline is completed, and each movable support should be uniformly stressed, and it is not allowed to partially hang up the sliding support, or the phenomenon that the pipeline is partially lifted due to the high support.
(8) The type of the steel beam for the fixed bracket shall be determined by design. No changes are allowed during construction. The section steel and the trench wall should be firmly connected.
(9) All the brackets fixed to the ditch wall should be buried deep, and the surrounding holes should be filled with bean stone concrete.
(10) Drill holes should be used, and then fixed by hanging rods, and holes should not be cut by gas welding.
