Tower Structural Support Chimney New Construction Notes
[Summary description] At the same time, organize electric welders to carry out the necessary training and assessment of welding technical essentials, and do a good job in the selection of construction personnel. Unqualified electric welders are not allowed to use them. The steel plate, the longitudinal seam of the longitudinal ring of the cylinder body are welded and welded manually and manually. The welding slurry must be full, the welding seam is smooth and flat, and there must be no pores. Then, let's learn about the precautions for new tower chimney construction! Before the start of construction, all participating construction personnel must be organized to guide and study carefully. At the same time, electric welders shall be organized to conduct necessary training and assessment of welding technical essentials, and the selection of construction personnel shall be done well. Unqualified electric welders shall not be used, and detailed construction shall be carried out. Safety and technical disclosure work, the winding method of the tower chimney in the on-the-job construction operation adopts the winding method of steel plates connected at the head and tail, and the longitudinal seam of the longitudinal ring of the cylinder body is manually and manually welded and welded. The welding slurry must be full, the welding seam is smooth and flat, and there should be no pores. Then, let's learn about the precautions for new tower chimney construction!
Anti-corrosion treatment of tower chimney
The fixing bolts of the tower chimney are respectively welded on the basic steel structure, and the distance distribution is reasonable and even. The installation of the steel chimney uses a large crane. When connecting the chimney barrel and the foundation screws, the angle between the wind rope and the ground is not greater than 60. After the overall hoisting and installation of the welding seam of the steel chimney is completed, the inner and outer cylinders of the chimney are fully coated for anti-corrosion. When painting, use double nuts to fix it. When it is lifted to a suitable position, pull up the wind rope and connect it with ground anchors. The wall surface of the chimney must be treated. Welding slag impurities are removed cleanly, the coating is uniform, the surface of the cylinder is smooth and bright, and the color is bright.
The steel plates used in the manufacture of tower chimneys must have steel quality inspection certificates, and all indicators must meet the requirements of Steel Chimney Design documents and relevant current national regulations. The use of substandard steel is prohibited.
When the steel arrives at the site, it should be classified and placed. Do not mix different gauges of steel. At the same time, it brings difficulties and unnecessary troubles to construction and production, and the bottom of idle steel products is flat to avoid artificial accumulation and deformation of steel products.
Welding electrodes used for welding must have product qualification certificates and meet the requirements of China's "Carbon Steel Welding Rod" GB5117 standard. In addition, please use it after passing the actual welding work test. Welding rods should be stored in a ventilated and dry place and taken immediately after use.
Advantages of tower chimney insulation control system
Safe, high temperature resistance, corrosion resistance, heat insulation, straight line, bright and beautiful, light weight. All products are factory made. Advanced production technology and easy maintenance. No preservative treatment is required. Its weight is 1/4-1/5 of the carbon steel chimney. The bracket is scientific and reasonable, and the chimney is stable and firm. Life expectancy is more than 50 years. The tower chimney does not require welding, making it easy to assemble on site.
The tower chimney has the advantages of convenient installation, heat preservation, beautiful appearance, light weight, maintenance-free, long life and corrosion resistance. The structural forms of the tower chimney are circular, rectangular and triangular. Products are divided into staged combination structure. Simple and reliable, beautiful and novel in appearance. It is an alternative to traditional cement chimneys and iron chimneys. According to needs, including Yuhu, Yuhu, Yuhu, Yuhu, Yuhu, Yuhu, Yuhu, Yuhu, etc., smoke exhaust device, explosion-proof device, regulating valve, etc.
In order to absorb the concentrated stress of flue expansion and cold contraction, a 20-25m corrugated compensator is generally installed. After the prefabricated components of the tower chimney have the advantages of convenient, fast and reliable installation, they can be assembled into pipes and chimneys in any direction according to site requirements.
The above are the precautions for new tower chimney construction. If you want to know more, please feel free to contact us!
