500kv Angle Steel Power Transmission Substation Architecture

    Our company is engaged in angle steel tower, steel bar, steel tower, power transformation and rich experience in large crossing tower and a variety of steel structure of production, The actual production has gradually accumulated mature steel structure processing technology and product inspection work instruction .For Shandong Huaan iron tower Co. Ltd. to undertake the processing more difficult crossing tower and lay a solid foundation. My company to take the following measures for the main working procedures during processing. The steel bar, steel tube tower, substation framework and large crossing tower, take the following


measures:
1.Blanking technology assurance measures
   Before Raw materials blanking, the first, leveling, after leveling plate the plane degree not only up to the standard requirements, but also can eliminate the residual stress, further to ensure the accuracy of the processing workpiece.
   Blanking equipment: Shandong Huaan iron tower Co. Ltd. equipped with advanced domestic large plasma cutting machine and CNC flame cutting machine, sheet leveling after entering the plasma cutting machine cutting, can realize high speed precision cutting, small workpiece deformation. For the plate of material, the selection of NC flame cutting machine, can realize the multi branch cutting torch to work at the same time, greatly improve the production efficiency. In order to achieve some regular shape and the workpiece material of blanking, the company is equipped with a large hydraulic shear thickness up to 20mm cutting plate machine and two shear 13mm large Shearing machine.
  Groove machining quality is an important factor related to the welding quality of welding, but also a key link in the process control, therefore, the company introduced the groove of advanced processing equipment, ensure the quality of groove machining workpiece meets the requirements of the standard, greatly promoting the Shandong Huaan iron tower Co. Ltd to improve the welding quality. The long straight pipe blanking: through the use of intersecting line cutting machine, it can realize the flame/plasma cutting, precision up to 1mm, fully able to meet the quality requirements of large crossing tower, completely solves the problem of the large crossing tower intersecting pipes under processing efficiency, and accuracy is not high. To ensure the intersecting pipes of this an important part of precision. Especially for spatial intersecting joint processing, its advantage is more outstanding. For some large diameter tubular production through Computer Lofting as sample to achieve, greatly reduces the accumulated errors produced by the past manual lofting, improves the precision of the workpiece.
2. Processing technology assurance measures of the main tube of the tower body
   The main tube as a main part of large crossing tower, its processing quality required high, difficult processing, mainly through strict control of pipe, tube stack, welding, correction and inspection procedures to ensure that quality of the main pipes.
   Tubulation: the company currently has 10 sets of various types of bending machine, to deal with 3mm - 40mm plate rolling process.         Assembly for the main tube: Shandong Huaan iron tower Co., Ltd developed the assembly station multifunctional hydraulic can realize the pipe weld gap free adjustment. Reserved strictly within technology licensing scope gap, at the same time with the comprehensive means test, to ensure the reserved space qualified competent longitudinal seam.
    Welding the main tube: the main technical assurance measures are three: welding equipment, control the welding material, control the welding process. Detailed inspection procedure guarantee measures:

4.Packaging technology assurance measures
    To ensure the quality of product delivered to the customer hands, especially the anticorrosion layer will not be reduced, Shandong Huaan iron tower Co., Ltd Adopted a series of measures to packaging, packaging classify of products, achieve good results.
5.Fast and efficient after sale service
    Shandong Huaan iron tower Co., Ltd leadership attaches great importance to customer service, and customer service quality as the extension of product quality. After sale service of software and hardware configuration gave high attention. At present, Shandong Huaan iron tower Co., Ltd has a number of high quality, first-class technology after sale service personnel. Fully capable of providing emergency treatment and other services to customers, the installation work quickly and efficiently with the user to complete various tower.
