Tin air duct has already become a widely used information in various equipment. Because of its low service life, the need for replacement and maintenance is often stopped. Its detailed equipment replacement methods, iron air duct is here to tell you.
1. Manufacturing and Installation of Support and Hanger
According to the requirements of the standard, different supports and hangers with different sizes are adopted for the iron ducts. The length of the suspender should be cut according to the scale and installation height of the iron duct and the height of the floor beam or steel frame. The hanging code of the hanger rod is machined with angle steel. The screw teeth at the end of the hanger rod should adjust the requirement of the elevation of the iron sheet air duct satisfactorily. The top of the hanger rod is welded and fixed with the angle steel code. The anti-rust paint and topcoat of the hanger rod are twice each. After the suspender is manufactured, the installation can be stopped according to the installation orientation of the sheet iron air duct, and the spacing meets the requirements of planning and standards.
2. Hoisting of iron duct
Stop the installation of iron ducts according to the requirements of planning drawings and national standards. Before installation of iron duct, do a good job of cleaning the assembly parts. After that, according to the distribution of the system of iron duct in the drawings, stop placing and assembling according to the number of the manufactured iron duct, check the scale of iron duct, and the axis orientation is in line with the drawings, it can be hoisted.
Hand hoist is used for hoisting, which can be coordinated by the hoisting team. Pay attention to the balanced lifting of the iron duct during hoisting, so as to prevent side slip or dumping. The iron sheet air duct is fixed on the support and hanger with angle steel cross-arm. When installing the iron duct, the supervisor shall stick to the bottom of the girder as far as possible, and the branch pipe shall be installed as high as possible. When crossing operation, we must coordinate with water and electricity harmoniously and pay attention to safety together. After the installation of the iron duct, check whether the installation height of the iron duct can meet the planning requirements, whether the degree and verticality of the iron duct can meet the standard requirements, whether the bracket can tilt, and whether the spacing of the bracket can meet the requirements.
Wind pipe reinforcement measures: rectangular duct side length (> 630 mm) and insulation duct side length (> 800 mm), pipe section length above 1.2 m must be reinforced or other reinforcement.
