quality Tank Welding Machine & Hydraulic Tank Jacking System manufacturer

In order to do a good job in the construction of long-distance pipeline, we must do a good job in the preliminary preparation of construction. If the construction preparation work is sufficient, the construction quality and progress will be guaranteed.   1, Maintenance, repair and purchase of construction equipment   Before construction, the construction machinery and equipment should be repaired to make it in good condition, especially the welding machine, pipe hanger, excavator, inner mouthpiece, air compressor, etc., must be in good condition. The welder should have a spare. The missing equipment should be purchased. A spark leak detector should be purchased for pipelines with spring rings. In the equipment maintenance at the same time to prepare for the construction of equipment, such as the production of external mouthpieces, lower ditch hanging basket, baking handle, ring heater, etc. Calibration of measuring instruments and pressure balances; Instruments used for recording are tested. Equipment, materials and tools for ball sweeping, diameter measurement and pressure test shall be prepared after the approval of the pressure test plan. Before construction, the water source of the pressure test should be considered, and the construction schedule and location of the pipeline should be considered. The air compressor, sand blasting tank, spray gun head, sand blasting hose should be maintained well, and the spray gun head and sand blasting pipe should be prepared more.     2, Obtain technical documents   Preparation of construction organization design, quality manual, quality control procedure documents, construction organization management (personnel organization and various management systems), process construction procedure documents, welding process assessment and welding process procedures and other necessary documents for pipeline commencement. At the same time, it is also necessary to prepare and submit highway and railway crossing plans; River crossing scheme; Bend and bend pipe as program documents; Pipeline through the ball pressure test scheme.     3, Training and certification of construction technicians   Construction technicians in key processes must pass the training and assessment and be certified to work. Management of construction welder training, certification is a large workload of work, input of manpower, funds, materials the most, to be carried out seriously. A leading group should be set up to take special charge of training. Responsible for organizing pipe processing, welding material procurement, welding machine and site preparation; Welding training, arrange technical guidance personnel and inspection personnel, organize certification. Skills in anti-corrosion work Technical workers, but also to carry out theoretical and practical training, take the job certificate. Mechanical operators and plumbers, grinders should also be trained, skilled after work.     4, Material preparation   How to supply the pipes and welding materials for pipeline construction, how to supply the anti-corrosion materials, and the procurement, supply and transportation channels of the second elbow pipe, equipment and valves should be carefully implemented. Grinding wheel, welding glass, disk wire brush, coarse sand for rust removal and other construction consumption materials, safety, fire protection materials such as fire extinguishers, fire buckets, shovel axes, labor protection clothing and supplies, etc., to be adequately prepared. The condition of the preparatory work shall be inspected by the owner and the supervisor; The preparation work is not sufficient, the construction quality is not guaranteed, the above necessary preparation work is not done, the owner and the supervisor are not allowed to start.   WINCOO ENGINEERING CO.,LTD can provide a full set of long distance pipeline construction equipment and various accessories.
