Q:Lightning protection grounding, what is called three surface welding?
When lap welding is adopted, the welding length is as follows:1, galvanized steel bar is not less than its width of 2 times, three surface welding. When the width of flat steel is different, the length of lap should be wide. Before laying, the flat steel should be adjusted straight, simmer, bend not to die, straight line should not be obvious bending, and should stand upright.2, galvanized round steel welding length of 6 times its diameter, and should be double-sided welding (when the diameter is not the same, the length of overlap in diameter should prevail).3, galvanized round steel and galvanized flat steel connection, its length is round steel diameter of 6 times.4, galvanized flat steel and galvanized steel pipe welding, in order to connect reliable, in addition to contact in itBoth sides of the site shall be welded, and the flat steel itself shall be bent in an arc to be welded with the steel pipe.
Q:What is the negative deviation allowed by the national standard for galvanized flat steel of 40*4?
40*4 galvanized flat steel GB permitted negative deviation value is the thickness deviation value is 0.2mm, the deviation 0.4mm, the width deviation value is the upper deviation 0.5mm, lower deviation 1.0mm
Q:What is the thickness deviation of 40*4 galvanized flat steel?
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:How to use -40*4 galvanized steel bar to do grounding electrode?
The combination of conductors or conductors that are buried in the earth so as to connect with the earth is called a ground electrode. The grounding electrode is the electrode which is in full contact with the ground and realizes the connection with the earth. In the electrical engineering, the grounding electrode is made of a plurality of 2.5M long, 45X45mm galvanized steel angles, and is nailed at the bottom of the 800mm deep groove, and then is drawn out with the lead out line.
Q:50*4 hot dip galvanized flat steel can be used as grounding. How many square feet can be used instead of ground wire?
You say flat steel grounding, and later said mountain laying, should be interpreted as the lead of the earth pole, grounding project called "zone"
Q:What is the representation of flat steel?
Flat steel is represented by -B*t. T- thickness; b- width.Flat, refers to the width 12-300mm, thickness 4-60mm, cross section is rectangular in shape and with a blunt edge of steel.
Q:Connect the equipotential terminal box to the ground flat iron. Can I use plain flat steel?
Specification requirement is 25*4 or 40*4 hot galvanized flat steel, said the family specification is also very reasonable, even galvanized flat steel, long time buried in the soil or on the floor, the wall will be laying, easy to rust, if we use the normal flat iron, not to mention that, certainly rust, but the speed is much faster than galvanized flat steel!
Q:Hot dip galvanized flat steel specification 40X4, 60X6 meaning?
Hello Hot galvanized flat steel specification 40* 4 stands for flat steel with a height of 40 mm and a thickness of 4 mm60* 6 stands for flat steel with a height of 60 mm and a thickness of 6 mm..
Q:Please: hot galvanized flat steel and copper clad steel ground!
Compared with galvanized flat steel and other grounding materials, copper clad steel ground wire features: 1, corrosion resistance is better: no residual inside the bimetal, better corrosion resistance. The horizontal continuous casting process adopts high temperature melting, and the residue is calcined to overflow the copper surface, and can not be left in the copper clad steel conductor, so the corrosion phenomenon can not occur inside. 2 、 better electrical performance: the surface of oxygen free copper, good conductivity, the inner layer of high-quality carbon steel, skin effect principle, conductive, magnetic characteristics are excellent. The resistance is much lower than conventional materials such as steel, galvanized steel, etc. the surface layer is oxygen free copper.
Q:How is three grade steel connected to ground flat steel?
HRB400 can be directly welded by hand arc welding with Q235 flat steel into electrical circuit. (I have done two sets of tensile tests last year, qualified).
