Q:Do lightning protection, lead out of the galvanized round steel, flat steel needs to be inspected?
No, when purchasing hot galvanized round steel and flat steel, please offer the factory certificate and inspection certificate.
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:Where can I buy ground level bending machine?
Galvanized flat steel and galvanized steel (or steel) for welding, reliable connection, should be in addition to the contact regions on both sides of the weld, should also direct the flat curved (or rectangular) and steel (or steel) and steel pipe welding, when welding on the steel pipe wrapped around the welding length 2 times less than the width of flat steel.
Q:Where is the use of flat steel in electrical use?
The flat steel used in the project consists of two types: galvanized and non galvanized. Galvanized is mainly used in decorative materials and pipes, such as rings, hoop and so on;
Q:How can copper cables and flat steel be welded together?
If it is filamentous, press press terminal (open type to cut tin). The terminal is pressed onto flat steel for corrosion protection. It is not allowed to be directly pressed to flat steel, so it must be brazed to flat steel by copper
Q:Hot dip galvanized flat steel specification 40X4, 60X6 meaning?
Section size of flat steel * width * thickness. Unit: mm.
Q:What is the appearance of hot galvanizing and cold galvanized flat steel?
Cold galvanizing is zinc plating, the amount of zinc plating is very little, only 10 - 50g/m2, and its corrosion resistance is much different from that of galvanized pipe. Regular galvanized pipe manufacturer, in order to ensure quality, most do not use electro galvanized (Leng Du). Only small enterprises with small equipment and old equipment use zinc plating, of course, their prices are relatively cheaper. At present, the Ministry of construction has officially completed the following, the elimination of backward cold galvanized pipe, the future is not allowed to use cold galvanized pipe for water, gas pipes.
Q:Is there a requirement for the ground resistance of the field motor? Is it good to use ground flat steel or ground wire?
The enclosure is grounded and the ground wire is the same, and the ground wire requirement is no more than 4 ohms. Generally, the motor shell can be connected to zero. There is no need to ground. In the power system, earthing and zeroing can not be mixed.
Q:The grounding electrode 50 angle steel and the ground wire 50, the flat steel lap welding, according to the specification 169 needs the flat steel to be late 90 degrees, bends close to the angle steel side, the overlap width is 4 times (200mm)?
GB50169-2006 in the 3.4.2 stipulates that the grounding body (line) shall be welded by lap welding, and its lap length shall comply with the following requirements:1. flat steel is 2 times its width (and welded with at least 3 edges);2. round steel is 6 times its diameter;3. round steel and flat steel connection, its length is round steel diameter of 6 times;
Q:80 * 80 * 4 galvanized flat steel is what specifications?
Galvanized square pipe.Specification: 80 * 80 * 4 is the dimension of galvanized square pipe. That is to say, the length and width of the inner diameter of the nozzle are 80mm, and the thickness of the tube wall is 4mm.
