How to avoid corrosion in steel structure engineering

-

 As we all know, the most afraid of steel structure engineering is corrosion, so how to avoid corrosion? Please be sure to have 3 necessary conditions at the same time, namely material, substance and tensile stress. Therefore, it is necessary to start from these three hazard elements, and take corresponding countermeasures from product design, installation engineering construction to important links in enterprise production management.

(1) Material: use duplex stainless steel; select welding consumables with basically the same composition and microstructure as the base metal (the principle of equal composition);

(2)  Substance: The possibility of corrosion of the base metal by the substance must be specifically considered, in order to reduce or remove stress corrosion in special environments, and corrosion inhibitors can be added to the substance.Metal surface treatment technology can also be used to prepare cathodic protective coating or physical barrier coating on the surface of prefabricated components;

(3)  Tensile stress includes: ① Select the appropriate joint form during the welding process to reduce the internal stress; ② Correct electric welding sequence; ③ Appropriate heat input; ④ After welding, stress relief treatment can be carried out.

With its excellent physical, mechanical and engineering construction properties, steel structures have been widely used in engineering projects around the world.However, corrosion of steel structures will not only cause huge waste of metal resources, but also endanger normal production operations.Therefore, it is necessary for steel structure manufacturers to actively develop new anti-corrosion countermeasures and give full play to a greater effect in future anti-corrosion and thermal insulation projects.

In what areas are steel structures usually used

Steel structure manufacturers can process a wide variety of products, including the following categories: 1. Single and multi-story industrial and residential buildings. 2. Office buildings, primary and secondary schools, hospitals. 3. Luxury villas, tourism buildings. 4. Modern commercial buildings for various markets. 5. Mobile buildings (demountable buildings, emergency projects). The main building materials in membrane structure engineering are steel and membrane materials. For steel structures, the main processing flow includes: material feeding → cutting → inspection → assembly welding → rust removal → numbering packaging → factory. The precautions are: 1. Materials must have a material certificate. 2. According to the cutting length and rod specifications calculated by the designer, the rods are classified and stacked for easy construction in the next step. 3. According to the penetration size of the steel pipe, considering the influence of wall thickness and groove, the automa...

Three Methods of Space Frame Installation

  What are the 3 methods of space frame  installation ? SAFS steel structure professional technical staff share with customers and friends:   1.  Splicing the entire space frame  directly, after the completion  of  the corresponding ceiling method to hoist the entire space frame  into the air, and then within a certain hovering time, weld the space frame  in the corresponding position and connect it with the whole  building . This method is faster  to install, but has higher requirements for operators. 2.  The method is relatively mild, the space  frame works directly at a high place, and the space  frame is installed bit by bit through the part that intersects with the building, that is, starting from the surrounding area and completing the work at the final center point. The schedule  is very slow, but the operation difficulty is also reduced a lot. 3. This method is mainly applicable to the quadrangular pyrami...

Space frame has become one of the important fields of modern architectural structure

Since the 20th century, the spatial structure has been greatly developed all over the world. The space frame structure is a kind of space grid structure. The so-called "space structure" is relative to the "plane structure", which has the characteristics of three-dimensional function. The space structure can also be regarded as the expansion and deepening of the plane structure. Since the advent of the space structure, it has been welcomed by people for its high-efficiency mechanical performance, novel and beautiful form, and fast and convenient construction. In stadiums, convention centers, cultural facilities, transportation hubs and even industrial plants that require large spans and large spaces, space structures can be seen everywhere.   After a century of continuous development of space structure, in terms of structural form, in addition to space frame and reticulated shell, membrane structure, tensegrity system, open and close roof, and foldable structure are...
