Chemical Plant Free Standing Steel Chimney

1.Material reception and requirements: The steel used in the production of steel chimney should be accompanied by a steel quality certificate, the indicators should meet the requirements of the design document and the current national standards, unqualified materials are prohibited to use. Line lead retest the vertical point of the chimney center, confirm correct before subsection connection, to prevent the chimney site installation due to different heart and safety risks. All the welding joints are broken by unit type. When welding, the weld is full without porosity, and the surface forming degree is smooth and flat. The welding personnel must have the welder qualification certificate issued by the national security department, and it is strictly prohibited to work without a certificate.
2.The electrode must have the product certificate and date, in line with the national "carbon steel electrode" standard provisions, welding before the electrode should be oven drying treatment.

1.The chimney loading needs to use a long ultra-wide truck, in the bottom of the truck according to the chimney conical external size welded anti-skateboard with a hand hoist to tighten the wire rope, in the binding of the wire rope with a soft mat.
2.The goods to the construction site, it is strictly prohibited to use forklift, forklift unloading. The crane should be used to safely unload the cargo in the correct lifting manner.

1. Before the chimney installation and lifting, the on-site technical supervisor shall submit the commencement report to Party A in advance, and organize the construction personnel to observe the site surface and surrounding buildings to make all preparations for the hoisting and installation.
2. Check the basic drawings and arrange technical personnel to test the horizontal point and center point of the foundation, so as to ensure that the chimney is not affected by wind and bad weather and can be used normally.
3. Before installing the cylinder body, use the crane to hang the upper taper of the chimney so that it is left or right from the ground. Note: In the process of chimney hoisting, to prevent the chimney deformation, it is strictly prohibited to use wire rope, special sling is required for lifting, in the conical degree of the mouth down about meters, with flat iron and Angle steel, in the Angle steel hole, easy to hang the outer foot triangular bracket, with full teeth bolts will be made of flat iron hoop hold tight to the chimney, and around the hoop with steel rope around two tight, A lanyard used as a seat belt.
4. According to the average spacing of each circumference inside the upper mouth of the chimney vertebra, weld the right-triangle iron plate about the thickness to facilitate the installation of the next section of the chimney and the butt of the chimney.
5. When the first section of the cylinder is installed after all the preparatory work is done, the truck crane is used for lifting and installation. The lifted chimney is placed on the foundation valve blue plate, and the center point is identified and then clicked and welded. After welding the bottom of the chimney, weld the height, width and thickness of the reinforcing plate in equal parts.
6. After welding the bottom of the chimney, the spare ladder made in advance shall be welded and fixed in a cross way according to the average calculation of each grid, and the climbing operation shall begin.
7. After putting on the safety hat and tying the safety rope, the climbing welding personnel should wear a loading rope and climb to the top of the chimney, hang up the pulley, and the ground personnel should pull the long and wide boards of the outer feet and hands to the top of the chimney. After being supported by the climbing personnel, they should gently put them on the triangular supports of the outer feet and hands and bind them.
8. When hoisting the second chimney, due to the lack of crane height, it is necessary to use the above crane to lift and install the second chimney on the top of the first chimney. When docking, it is necessary to hoist the vertical line of the center of gravity of the chimney.
9. Due to the bumps in the car during transportation, the chimney may be slightly deformed. If there is any dislocation during docking, iron plug and mechanical roof shall be used to correct it. Welding shall be carried out according to the requirements of welding specifications. After cooling, the antirust primer and top coat shall be applied again to hoist the third section cylinder.
