  管道连接是工程建设中非常重要的环节,直接关系到工程的质量。随着管道行业的快速发展,管道连接方式越来越多。
  Pipeline connection is a very important link in engineering construction, which is directly related to the quality of the project. With the rapid development of pipeline industry, there are more and more ways of pipeline connection.
  1. 螺纹连接
  1. Threaded connection
  2-3切线时,螺纹应清晰、完整、光滑,无毛刺和乱丝。如果线程中断或丢失,则不应超过线程总数的10%。螺纹也应该满足装配公差的要求,锥度为1/16,以防止螺纹之间太松或太紧配合。拧紧后,露出2-3个螺钉端部,去除多余的填充物,露出的牙齿涂上红色防止生锈。红漆刷幅一致,涂布均匀,无流动、漏涂现象。

  2-3 when cutting thread, the thread shall be clear, complete and smooth without burr and mess. If a thread is interrupted or lost, it should not exceed 10% of the total number of threads. The thread shall also meet the requirements of assembly tolerance with a taper of 1 / 16 to prevent too loose or too tight fit between threads. After tightening, expose the ends of 2-3 screws, remove the excess filler, and coat the exposed teeth with red to prevent rust. The red paint has the same brush width, uniform coating, no flow or missing coating.
  2. 法兰连接
  2. Flange connection
  法兰生产应平法兰,对角线长度相同的情况下,完整的焊缝,法兰螺栓孔和铆钉间距均匀,按照需求的代码,四角的螺丝孔的法兰,法兰连接的方向应该是统一的,一致的长度、螺栓材料和相应管道。
  Flange production should be flat flange, when the diagonal length is the same, complete weld, flange bolt hole and rivet spacing should be uniform, according to the required code, the flange of four corner screw hole, flange connection direction should be uniform, consistent length, bolt material and corresponding pipeline.
  3.焊接连接
  3. Welding connection
  根据规格要求,槽型一般为V型,槽角60-75度,对间隙2-3mm。使用此刀片时不得超过壁厚的10%,并使用2mm;使用这种3毫米脉冲墙。
  According to the specifications, the groove is generally V-shaped, with a groove angle of 60-75 degrees and a clearance of 2-3mm. When using this blade, it shall not exceed 10% of the wall thickness, and 2mm shall be used; use this 3mm pulse wall.
  4. 槽连接
  4. Slot connection
  检查管道的尺寸、圆度和制造质量,以满足制造坡口的要求。槽应按规定的时间分阶段加工,并对槽的深度和其他尺寸进行重测。在加工坡口时,不得损坏钢管的镀锌层和内涂层。
  Check the pipe size, roundness and manufacturing quality to meet the requirements of manufacturing groove. The groove shall be processed in stages according to the specified time, and the depth and other dimensions of the groove shall be retested. During groove processing, the galvanized layer and inner coating of steel pipe shall not be damaged.
  5. 卡连接
  5. card connection
  清除插入端口并标记插入深度。在指定的深度插入管道,保持轴线垂直。用专用工具夹紧连接器,夹紧后用量规检查夹紧尺寸是否到位。
  Clear the insertion port and mark the insertion depth. Inserts the pipe at the specified depth, keeping the grid line vertical. Clamp the connector with special tools, and check whether the clamping dimension is in place with gauges after clamping.
  6. 热熔连接
  6. Hot melt connection
  清洗热熔件和承插接头,标明热熔深度。使用专用熔炼机按规定的加热时间对连接部件进行加热。加热后按规定的压力和时间熔合接头,在接头处形成均匀的熔合环。
  Clean the hot-melt parts and socket joints, and mark the hot-melt depth. Use the special melting machine to heat the connecting parts according to the specified heating time. After heating, the joint is fused according to the specified pressure and time to form a uniform fusion ring at the joint.
  7. 套接字连接
  7. Socket connection
  铸铁管连接前,应将影响接头密封性的杂物清理干净,正确放入橡胶密封圈内。按施工标准要求的深度插入并保持两个断面的垂直度。
  Before connecting the cast iron pipe, the sundries that affect the sealing of the joint shall be cleaned and put into the rubber sealing ring correctly. Insert and maintain the perpendicularity of the two sections according to the depth required by the construction standard.
