1、螺纹联接操作工艺断管管段调直套丝配装管件设备

1. Thread Connection Operation Technology Straightening Sleeve for Pipe Fittings in Broken Pipe Section

1)套丝用电动套丝机,圆锥形管螺纹应契合国家标准《用螺纹密封的管螺纹》GB/T7306-1987的要求。管径DN25mm以上要分两次以上套丝,不行一次套成,管子螺纹要规整,不得有断丝或缺丝等缺陷。

1) The threads of conical tubes in electric threading machines for threading shall meet the requirements of GB/T7306-1987. Pipe diameter above DN25mm should be divided into more than two sets, not one set, pipe threads should be regular, no broken or missing wires and other defects.

2)管螺纹加工时应根据管径的不同,别离选用相应的绞板和板牙,加工时用力要均匀。加工好的螺纹应规矩不乱扣,光滑无毛刺,完好不掉扣,松紧程度恰当。

2) Pipe thread processing should be based on the different diameter of the pipe, separately choose the appropriate winch and plate teeth, processing force should be uniform. Processed threads should be regular, smooth, burr-free, intact and tighten properly.

3)管道螺纹联接时,在管子的外螺纹与管件或阀件的内螺纹之间加油麻,先将麻丝抖松成薄而均匀的纤维,从螺纹的第二扣开端沿螺纹方向进行盘绕,涂白胶漆,然后拧上管件,再用管钳收紧。填料盘绕要恰当,不得把白胶漆、麻丝挤入管腔防止堵塞管路。

3) When connecting the pipe threads, oil the linen between the external threads of the pipe and the internal threads of the fittings or valves. First, shake the linen threads into thin and uniform fibers, coil them in the direction of the threads from the second fastening end of the threads, coat them with white glue paint, then screw on the pipe fittings, and tighten them with pipe pliers. Packing should be coiled properly. White glue paint and linen should not be squeezed into the pipe cavity to prevent blockage of the pipe.

4)设备螺纹管件要按旋转方向一次装好,不得倒向旋转设备,暴露2-3扣螺纹,并铲除剩余填料,不得暴露油麻,镀锌管的暴露螺纹、一切钳痕和表面损害部位需刷防锈漆。

4) The threaded pipe fittings of the equipment shall be installed in the direction of rotation once, and shall not be reversed to the rotating equipment, expose 2-3 threads, and remove the remaining fillers, and shall not expose oil flax. The exposed threads of galvanized pipes, all pliers and surface damages shall be brushed with anti-rust paint.

5)管道及阀件的丝扣联接应在专用台具上进行,防止因丝扣联接形成管道直线度误差过大而影响管道漂亮。当管段丝扣部位出现弯曲时,应给予纠正,无法纠正时须拆开丝扣件从头联接。

5) The thread connection of pipes and valves should be carried out on special benches to prevent the pipeline from being beautiful due to the excessive straightness error caused by the thread connection. When the buckle part of the pipe section is bent, it should be corrected. When it cannot be corrected, the buckle must be removed and connected from scratch.
