Standard Sheet Of Galvanized Flat Iron

Standard table value trust of galvanized flat iron Keep the warehouse clean and strengthen the maintenance of materials (1) pay attention to prevent rain or impurities from entering the warehouse before the materials are put into the warehouse, and clean the materials that have been rained or soiled by different methods according to their properties, such as wire brush with high hardness, cloth and cotton with low hardness, etc.; (2) check the materials frequently after they are put into the warehouse, and remove the rust layer if there is rust; (3) clean the surface of general steel pipes After that, it is not necessary to apply oil, but for high-quality steel, alloy steel sheet, thin-walled pipe, alloy steel pipe, etc., after rust removal, the internal and external surfaces shall be coated with anti rust oil before storage; (4) for steel pipe with serious rust, it is not suitable to keep it for a long time after rust removal, and it shall be used as soon as possible.

It is mainly used for coal mine ventilation, drainage, vertical shaft gas drainage. Fourth. Large diameter electric welded square pipe for low pressure fluid transmission, standard GB / t14980-1994. Indicates material q235ab level. It is mainly used for conveying low-pressure fluid, such as water, sewage, gas, air, heating steam, etc. Fifth, the mechanical structure of stainless steel welded square tube, standard number is GB / t1270-1991. The materials are 0Cr13, 1Cr17, 900cr19ni11, 1Cr18Ni9, 0cr18ni11nb, etc. It is mainly used for machinery, automobile, bicycle, furniture, hotel decoration and other mechanical parts and structural parts. Sixth. Stainless steel welded square tube for fluid delivery. The standard number is GB / t1271-1991. The representative materials are 0Cr13, 0Cr19Ni9, 00cr19ni11, 00Cr17, 0cr18ni11nb, 0017cr17ni14mo2, etc., which are mainly used to transport low-pressure corrosive media. Seventh. Standard No. of low pressure conveying spiral pipe (Ministry of petroleum): SY / t5037.2008.

The flat steel of 10 mm can be used to make hoop iron, tools and mechanical parts as a product, and it can be used as a building frame structure and escalator. Features of 10 mm flat steel 1. Flat steel is rolled with negative deviation, but delivered according to the actual weight, the utilization rate is 1-5 percentage points higher than that of steel plate. 2. Flat steel can be produced according to the user's requirements, with fixed thickness, width and length, which reduces cutting for the user, saves working procedures, reduces the consumption of labor and materials, and reduces the processing loss of raw materials, saving time, labor and materials.

The hydraulic punching and shearing machine is composed of fuselage, main cylinder, motor, etc. The machine body is composed of upper crossbeam, sliding block, workbench, column, adjusting nut and locking nut. The main frame of the equipment is the fuselage, the sliding block is connected with the piston rod of the main cylinder and moves up and down depending on the fuselage guide rail. The fuselage and worktable are all of steel plate welding structure, with post welding aging treatment to effectively eliminate internal stress. This machine has the advantages of strong universality, high precision, reliable performance and easy operation.
Angle steel can be used to form different load-bearing members according to the different needs of the structure, and can also be used as the connection between members. It is widely used in building structures and engineering structures, such as beams, bridges, transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container racks and warehouse shelves. Angle steel is a kind of carbon structural steel for construction. It is a simple section steel. It is mainly used for metal components and frame of factory building. Good weldability, plastic deformation performance and certain mechanical strength are required in use. The commonly used materials of galvanized flat iron standard table value trust welded pipe are: Q235A, Q235C, Q235B, 16Mn, 20 × 20, Q345, L245, L290, X42, X46, X60, X80, 0Cr13, 1Cr17, 00cr19ni11, 1Cr18Ni9, 0cr18ni11nb, etc. It can be divided into general welded pipe, galvanized welded pipe, oxygen blowing welded pipe, wire sleeve, metric welded pipe, idler pipe, deep well pump pipe, automobile pipe, transformer pipe, thin-walled electric welding pipe, special-shaped electric welding pipe, scaffold pipe and spiral welded pipe.
Under the same section load, the weight of hot-rolled H steel structure is 15% - 20% less than that of traditional steel structure. ◆ compared with the concrete structure, the hot rolled H steel structure can increase the use area by 6%, while the self weight of the structure can be reduced by 20% - 30%, reducing the design internal force of the structure. ◆ H-shaped steel can be processed into T-shaped steel, and honeycomb beam can be combined to form section form, which greatly meets the engineering design and production requirements. Application scope: H-shaped steel is mainly used for beam and column components in industrial and civil structures.
Chemical composition: (1) composition index: the chemical composition of angle steel belongs to rolled steel series for general structure, and the main inspection indexes are C, Mn, P and s. According to the different brands, the contents are different, the approximate range is C < 0.22%, Mn: 0.30-0.65%, P < 0.060%, s < 0.060%. (2) Test method: for the above chemical components, the commonly used standard test methods are gb223, jisg1211-1215, bs1837, BS manual 19, γ ОСТ 22536, etc.
