Eye bolts are standard fasteners and are manufactured from 20 or 25 steel. Widely used in electromechanical products, its main function is to lift the load. Eye bolts must be forged in one piece. Forgings should be normalized and scale removed. The grain size of the finished product should not be less than grade 5, and the forgings should not have over-burning and cracking defects.
Below is the content list
Surface treatment of eye bolts
Selection principle of eye bolts
Application of eye bolts
The lifting eye bolts are generally not surface treated, but according to the requirements of use, surface treatment such as galvanized passivation and chrome plating can be carried out. Lifting eye bolt surface treatment: CORRUD-DT, the anti-corrosion effect of this surface treatment is at least 20 times stronger than that of ordinary galvanized treatment. The length of the external thread is "H", and the bolts are fixed with other parts. When replacing, the bolts of the same quality must be used, and the material is generally 304 stainless steel. The strength of the lifting eye screw is 12.9.
The structural form and size, technical requirements, lifting weight, and conditions of use of eye bolts are specified in detail. Therefore, in addition to standard parts factories, other manufacturers are mainly selected. The principle of choosing eye bolts is: first, ensure the safety of operation, and then consider factors such as connection size, so as to be safe, economical and beautiful. The correct selection and use of eye bolts require analysis of the stress situation, careful study of the content specified in the standard, and strive to have a more thorough understanding. The lifting eye bolts are made of alloy steel with high reference to the German RUDWBG type. The products are exported to Europe and the United States in large quantities, and have passed the local G80 standard inspection. Better material than existing domestic eye bolts, higher tensile strength, and provide tensile strength test report.
Lifting eye bolts are widely used in ports, electric power, steel, shipbuilding, petrochemical, mining, railway, construction, metallurgy and chemical industry, automobile manufacturing, plastic machinery, industrial control, highway, large-scale transportation, pipeline auxiliary equipment, slope tunnel, shaft management and protection, marine Machinery and equipment for important industries and infrastructure projects such as rescue, marine engineering, airport construction, bridges, aviation, aerospace, stadiums, etc.
To sum up, the application of lifting eye bolts is very wide, and there are also principles in the selection. Do you have any further understanding of the above products about lifting eye bolts?
The company was established in 2001, specializing in the production of various types of high-strength bolts, nuts, and screws, with an annual production capacity of 30,000 tons and an annual turnover of 300 million yuan. Products include ANSI/ASTM, DIN, BS, ISO, GB, JS, and other standards, mainly used in the field of high-strength seals and oil pipeline valves.
