Galvanized duct length according to the conditions of the building, air duct wall thickness galvanized iron pipes, lifting and hoisting equipment with methods determined group can be put to good duct flanges at both ends as the reference point to the middle flange of the measuring point, measuring duct connection cable is straight galvanized iron duct thickness, large deviation to be adjusted, the front lifting, want to wind pipe support and hanger, lifting equipment, lifting equipment chosen branch, hanging point Sheet metal duct processing plant, is correct, firmly checked before lifting to carefully check, the rod is fixed ropes, lashing reliable and to remove all kinds of insecurity within the lifting range. Galvanized angle iron cross arm effective wind flow on the hanger. Duct means, the competent overly attached to the beam end, the manifold also make high devices. When the work will certainly be interspersed with water facilities, electricity facilities harmonic cooperation is good, at the same time pay attention to safety. After a good means of galvanized tin wind pipe duct prices, examine whether the level of the duct means satisfied the provisions envisaged, the degree of duct, verticality can match standards, can tilt bracket, bracket distance whether compliance with the regulations.
