Q:How to connect the base of the tower crane and the flat steel? How can it be welded and connected?
How to connect the base of the tower crane and the flat steel?:It can be punched on a flat iron and connected by screws and multiple copper wires
Q:Is the earthing electrode made of galvanized flat steel or bare copper wire?
The vertical earth body buried in the soil should be made of angle steel, steel pipe or round steel. The horizontal grounding body embedded in the soil should be made of flat steel or round steel. Round steel diameter should not be less than 10mm; flat steel section should not be less than 100mm2, its thickness should not be less than 4mm; angle steel thickness should not be less than 4mm; steel pipe wall thickness should not be less than 3.5mm.
Q:The distinction between flat steel and steel strip
Blue is to heat the steel or directly immersed in concentrated oxidizing solution in the air, material protection technology of oxide film on the surface of thin produce, also known as black. The blue steel parts can be carried out in the molten salt of sodium nitrite and sodium nitrate, can also be carried out at high temperature above 500 DEG C hot air and superheated steam, the more common is heating sodium nitrite in concentrated caustic soda. Solution composition, reaction time and the temperature of Bluing depends on steel matrix composition. Bluing film composition is magnetic iron oxide, the thickness of 0.5 to 1.5 microns, the color and the material composition and process conditions, a dark gray, dark blue, etc.. Bluing film separate corrosion resistance is poor, but the oil wax or paint varnish, corrosion resistance and friction resistance are improved. Blue, the workpiece has little effect on the quality of size and finish. It is commonly used in precision instruments, optical instruments, tools, hardness blocks and so on.
Q:Lightning protection grounding, what is called three surface welding?
The grounding position of the grounding body shall not be less than 3m; when the ground is embedded in the garbage or ash, it should be changed and compacted.The grounding body (line) shall be connected by welding, the welding seam should be full and adequate mechanical strength, no slag, undercut, crack, weld, welding defects such as pores, knocking the net after a drug paper, brush asphalt anticorrosive processing.
Q:What is the negative deviation allowed by the national standard for galvanized flat steel of 40*4?
40 is the width of the section steel, 4 is the thickness of the steel, and the unit is mm.Flat, refers to the width 12-300mm, thickness 4-60mm, cross section is rectangular in shape and with a blunt edge of steel. Flat steel can be finished steel, or can be used as the blank of welded pipe and thin slab for laminated sheet rolling.
Q:50*4 hot dip galvanized flat steel can be used as grounding. How many square feet can be used instead of ground wire?
GB is not 50*4, but 4*40; International Electrotechnical union IEC is 3*25 can also, and if it is small houses, GB only 6mm diameter of it. It can be seen that the size of flat steel is mainly due to the consideration of mechanical strength and more than the consideration of electrical performance
Q:Earthing flat steel, width, overlap face, bolt, big country net
Now it's basically 12mm open holes. Coupled with the expansion screw directly fixed on the wall of the backward technology, electricity and telecommunications has been the traditional practice.
Q:Can roof strip be replaced with steel pipe instead of flat steel and round steel? Are there any examples of practical use?
Steel pipes can be used instead of flat steel or round steel, and some of the structures on the buildings are connected and grounded by using steel pipe handrails on the walls of their daughters.
Q:Is medium plate steel flat?
Flat, refers to the width 12-300mm, thickness 4-60mm, cross section is rectangular in shape and with a blunt edge of steel. Flat steel can be finished steel, or can be used as the blank of welded pipe and thin slab for laminated sheet rolling. Main application: flat steel is used as a material, used for making iron, tools and machinery parts, and used as frame structures and escalators for buildings.
Q:How is three grade steel connected to ground flat steel?
Steel bars welded with flat bars should be of little size, 12mm bar, and if you are not sure, you can use a section of HRB335 over.
