Process introduction:

Hot dip galvanizing is an excellent coating method for protecting steel base. It is in the liquid state of zinc, after a rather complex physical and chemical action, not only on steel plating thick pure zinc layer, but also a Zn-Fe alloy layer. This plating method not only has the characteristics of corrosion resistance of electro galvanizing, but also has the Zn-Fe alloy layer. It also has strong corrosion resistance that can not be compared with electric galvanizing. Therefore, this plating method is especially suitable for a variety of strong acid, alkali fog and other strong corrosion environment.

Application:

Chemical equipment, petroleum processing, Marine exploration, metal structure, electric power transmission, shipbuilding, etc.), agriculture (such as: sprinkler irrigation, heating house), construction (such as: water and gas transmission, wire casing, scaffolding, housing, etc.), Bridges, transportation, etc.

Q: Cable tray specifications are generally how to choose: Cable bridge selection design . to determine the environmental conditions Environmental conditions are generally three: corrosive environment, the normal environment, special environment. . according to the majority of cable, in the room can be along the column, beam, floor walk, as far as possible in the process along the pipeline to go. . calculate the load calculation in the cable bridge to the cross section of the unit length of the cable weight q and the total load GG total = n1q1 + n2q2 ... ... nnqn where: q1 q2 q3 ... ... qn for each cable unit weight (kg / M) n1 · n2 · n3 ... nn is the same number of cables G total <G (the allowable load of the cable to the reference load curve chart) . select the bridge according to the cable load and bridge installation of the environment to the bridge Load curve as the basis, to determine the type of bridge and specifications and column spacing, the length of the arm, the bridge level, the length of the column and so on. . according to the cable to the installation and installation of the environment to determine the fixed way of the bridge; hanging, vertical, (these two forms can be used unilateral fixed or bilateral fixed), wall side and so on. . a variety of cables in the cable bridge on the level of arrangement and inter-layer distance. Cable bridge level arrangement is: weak control cable in the top, then the general control cable, low-voltage power cables, high-voltage power cables in order: the following table: This arrangement is conducive to shielding interference ventilation, heat and so on.

Q: Such as: 200 * 100 * 1.5. Ordinary, galvanized and hot galvanized. How is the price calculated? Is there a formula? More: The price of the single meter is determined by the type of the bridge and the cost of the raw material, as well as other accessories and labor costs. Calculation method: the various types of bridge after the expansion of the area × size × raw material density × raw material cost unit price.

Q: Is the bridge mounted above or below the water pipe? Is the top of the heating tube below?: Red, green, yellow, blue, yellow and green, red, green and yellow is a three-phase line of fire, blue is the zero line, yellow and green is the ground, your home switch red fire line, the rest is the control line, Socket red is the line of fire, green is the zero line, yellow should be ground. It is best to find a professional to see

Q: Metal trunking national standards, wire and cable bridge national standards: until the automatic search after the program, you can watch the TV program

Q: Our drawings are messy, some cableway or walk the bridge it also wear steel pipe, I would like to have this need to explain, we this project is the highest 23 layers more: . cable and wire are generally by the core line, insulation foreskin and protective skin composed of three components. The wire is made of one or several soft wires, with a soft jacket; the cable is made of one or several insulated packets, and the outer layer is covered with a tough outer layer of metal or rubber. . the two are not strictly bound. Usually less than the core number, the product diameter is small, the structure of a simple product called the wire, there is no insulation called bare wire, the other known as the cable; conductor cross-sectional area larger (more than 6 square millimeters) known as large wire, Small (less than or equal to 6 square millimeters) is called a small wire, insulated wire, also known as cloth wire. Cables are generally more than two layers of insulation, mostly multi-core knot.

Q: What is the safety distance between the bridge and the bridge?: Because the strong current generated by the electromagnetic field will interfere with the weak line.

Q: Steel cable bridge installation, how far a boom: Cable bridge standard JB-T-2000 only said that the support hanger selected materials should be consistent with their own relevant provisions; various types of hanger should be able to withstand the appropriate specifications (layers) tray, ladder rated uniform Load, meet the strength, stiffness and stability requirements. The ratio of the maximum deflection value of the cross brackets or side brackets of the steel hanger to the rated load shall not exceed 1/100 of the length of the hanger itself. Arm for the aluminum, it should not be greater than 1/150. Normal 2 meters, but also design 1.5 meters, or 1 meter.

Q: I checked the technical specifications of the above is written with a straight line of steel cable bridge more than 30 meters need to set the expansion joints. What is the reason? More: Computer power has 12V, in the power plug to find a free 4P plug, between the yellow line and the black line is 12V, then you can

Q: I would like to ask you, you generally do steel plant, how to lay the bridge feel better? I have some drawings, 1. Some of the bridge laying in the I-beam column, 2. Some of the bridge laying on the wall, 3. There are bridges along the steel roof truss lay, I went to know the appearance of steel roof truss, There are winding, chord, the middle of the abdomen is used to insist on the upper and lower sides, but that is along the winding, roof truss sometimes not linear level, sometimes for example triangular steel truss, not the level of the winding how to walk it? Is it easy to walk? Do not know where you design steel plant, the bridge how to design the best, the most appropriate? Thank you! More: What is the number of air conditioning is usually called, according to the air conditioning power consumption to estimate the amount of air conditioning cooling. In general, the habit of using a equal to 2500W of cooling capacity (that is, 25 models), 1.5 is about equal to .3500 amount (that is, 35 models). 1.5 for 16 to 26 square meters. 4 square of plastic copper wire can be 10kw enough to take the green line. 2.5 square steel wire can accommodate 3500W can also be. Preferably 4 square meters of plastic copper line is good

Q: Hello to ask a question, high pressure (10KV) bridge and weak bridge can be installed with a horizontal horizontal installation: Textbook on the standard answer tube threading length = (piping length + reserved length) X wire root number of the formula is not the same length of the reservation, such as the line is 1.5m, from the ground pipe exports caused by power connection box is 1.0 ... ... generally consider the line length is 1.5 times the length of the tube just fine, the size of the difference according to the actual workload to change like.
