Bo cause production technology for street light poles in the previous article has been mentioned in the production of 250-watt sodium lamps which company is good, from cutting, bending, welding, grinding process, etc., to the last street light pole forming In subsequent articles we will do reports, and in this article, the main street pole bending process is carried out to refine the presentation. Now, after the street light pole manufacturers are purchasing their own good to the factory for processing steel bending, so cost savings, because steel prices are low, and can be bent into a light pole you need to bend under lights they want production, manufacturers need only to buy a pipe bending machine can. Street light pole after cutting steel making, they should be bending. Factories in bending a steel pipe when the best 250-watt sodium lamps where to find, according to street light pole designers to design according to customer requirements get out drawings for processing operations, and as an operation master pipe bender, you know To bend the tube diameter, wall thickness, steel pipe weld processes. Why should understand these data, since the radius and bending machine related processing technology steel pipe bending and street poles determined relevant. Street light pole steel surface can occur if bent too small folds 250 watt sodium lamps, so to determine the minimum bend radius of 250 watt sodium lamps steel pipe price how do you know, because now is a street light pole bending machines operate on their own, So the case if you need to rely on experience to determine the bending radius, the proposed purchase bending machine can dial phone manufacturers, for technical advice, this problem is easily solved. Bo said the cause of some companies now sell not only street light pole, street lamps, while providing support construction services. At this time, if you have such a need, you provided the company with the drawings, the manufacturer will send a site survey to determine the size of the project the amount of quotes, and finished in the newspaper price, and street construction company reached, what you need to pay attention? In this article and you specific description. Manufacturers cooperate in determining the construction, it will be the overall implementation plan street construction. First, according to the construction drawings and site conditions, a pitch designed to determine between lamp post lights installed. Then according to construction plans embedded pipe trench excavation cable, pay attention to the upper part of the cable channel should be slightly higher than the ground, stamped with the production of concrete cover, and no debris to facilitate embedded trench corresponding cable duct. Cable pipe connections, corrosion should be specified. About connecting cable pipe, here are metal and plastic cable ducts points. Short sleeves metal cable pipe connection should be firm, two nozzle should be aligned with the length of the joint should not be less than 2.2 times the outer diameter of the cable pipe, socket, or Bands threaded pipe, metal conduit should not be directly welded seal should be well . Hard plastic pipe at socket or plug, the insertion depth should be 1.1 to 1.8 times the inside diameter of the pipe. The docking surfaces should be coated with glue cement seal, using socket casing ends should be closed when welding.
