Hainan Steel teach you: Steel structure installation techniques

Installation is the fabricated steel construction and boiler equipment assembled to apply to the boiler equipment operation support construction. Steel structure installation and manufacturing technology are closely related, and all installation procedures are based on manufacturing technology program, depending on the technician must control the use of steel structure installation technology. Steel structure installation technology should pay attention to before installation, installation, after the installation of the three aspects of the request.
1, before installation. Boiler steel structure installation technology design is a systematic process, the installation is the first step of the manufacturing technology. Specific measures: ① check. Small shaped structure has been fabricated and subject to verification process to ensure that its structure and boiler equipment performance to match. Such as: should ensure that distortion of steel and steel plate, lateral bending, straightness are corrected to meet specifications requested. ② clean-up. Timely removal of small impurities premise is to ensure quality of the installation, the installation need to be welded at the oil, rust and dirt to clean up and prevent the emergence of small steel structure installation gap.
2, installation. The installation process is the key to the implementation of the steel structure manufacturing planning, installation quality resolution of boiler equipment basically external performance. Specific measures: ① assembly. Assembly of the welding seam on the adjacent parts stagger distance, install beams and columns must be in the platform or high shelves were positioned, the two end faces of the same steel beam or column reference must be aligned [4] Note that the beam length, allowing splicing The number of joint shortest splice length. ② fixed. The beam should be installed and firmly secured section scale drawings and specifications comply with the request after assembly and welding technical support, assembly and welding technical support should be measured again after the section scales.
3, after installation. Complete boiler steel structure installation work has ended does not mean that, post-installation configuration needed to carry out the necessary maintenance to sufficiently improve the properties of steel boiler, which is manufacturing technology is important to mention the content. Specific measures: ① debugging. Under certain conditions the engine boiler commissioning, observe whether the steel structure in a stable state, there are unusual circumstances the extent of the mounting member to view portfolio. ② maintenance. Check regularly to maintain steel structure, such as: welding seam connection, deformation and other steel components, abnormal problem timely repair process. Hainan Steel
