Communication power power pole foundation piling steel rod steel rod

For welded steel pipe has a unique understanding and professional and technical requirements, the production process is taken into account the power of steel pipe under load, electricity is mainly affected by interaction steel pole transverse moment and shear force. Steel pipe welds in this joint effect, effective stress reduction factor is large, easy to produce stress concentration, so easily broken transverse weld shaft should be minimized to avoid transverse weld production. It is worth noting that, due to the field welding of objective conditions are relatively poor, human factors can not be controlled, field welding steel pole electricity power lines for great safety hazard, where there are many reasons, first steel pole when docked, because steel weight and environmental impact section can not achieve the desired docking, causing two steel pole is not a straight line; secondly, site welding process technology can not achieve the desired requirements, only the outer welded steel rod, not the internal processing of steel rod, direct cause stiffness steel rod was severely affected; again, on the power of welding steel rod embalmed difficult, especially internal corrosion, if not handled improperly, it is easy to corrosion of steel inside, directly affects the strength of steel rod. Arima Power Equipment Co., Ltd. in order to avoid the above conditions on the steel body, electrical steel pole rigorous on-site welding.
