In the installation of water pipes and components, threaded connection, welding and flange connection are several commonly used connection methods. For example, the system's risers, branch pipes and other pipes with smaller diameters are commonly connected by threaded connection, and the main pipes, outdoor pipes, etc. are generally welded. The valves, pressure reducing valves, decontamination devices and other pipeline accessories are connected to the pipes. Which method is selected according to the specific situation during the construction process.
钢管螺纹连接与管螺纹加工：一般管径在15-40mm的小管子都采用螺纹连接，定期检修的设备也采用螺纹连接，使拆卸安装较为方便，管螺纹的规格符合规范要求，管子和螺纹阀门连接时，管子上的外螺纹长度应比阀门上内螺纹长度短1-2mm扣丝，以避免因管子拧过头顶坏阀芯，同理，其它接口管子外螺纹长度也应比所连接配件的内螺纹略短些。 Threaded connection of steel pipe and pipe thread processing: Generally, small pipes with a diameter of 15-40mm are connected by threaded connection. Equipment that is regularly inspected and repaired also uses threaded connection to make disassembly and installation more convenient. The specifications of the pipe threads meet the requirements of the specifications. When the pipe is connected to the threaded valve, the length of the external thread on the pipe should be 1-2mm shorter than the length of the internal thread on the valve to avoid damaging the valve core due to the pipe being screwed over the head. Similarly, the length of the external thread of other interface pipes should also be slightly shorter than the internal thread of the connected accessories.
管螺纹加工：从质量方面要求，螺纹应端正，光滑无毛刺，无断丝缺口，螺纹松紧度适宜，以保证螺纹接口的严密性，填充材料可采用聚乙烯胶带管麻丝混白铅油。 Pipe thread processing: From the quality requirements, the thread should be straight, smooth and free of burrs, broken wires and gaps, and the thread tightness should be appropriate to ensure the tightness of the threaded interface. The filling material can be polyethylene tape, hemp fiber mixed with white lead oil.
钢管焊接：要求焊缝处无纵横裂纹，气孔及夹渣；管子内外表面无残渣，坑和明显的焊瘤，通常用水压试验，试验压力为工程压力的1.25-1.5倍，要求在规定的试验压力下进行检查，不渗水漏水为合格。管道穿过建筑物基础预留孔洞的尺寸一般比管径大2倍左右，并加设套管，套管中用保温材料填空，如果穿过楼板套管上端应高出地面20mm，防止上层房间地面水渗流到下层房间，下端与楼板底平。 管道支架，根据结构形式可将支架分为托架、吊架、管卡三种。前两种托吊水平管道，多在现场制造，管卡固定立管可采购，一般士干管离墙或柱子表面净距不小于60mm，产支管离墙净距为30mm。所有预留孔冻及支架埋设处的墙面应在管道安装后，装修工程完工前填堵。管路连接后要保证10m管卡上，当直径d<100mm时，纵横方向的弯曲允许偏差小于5mm；d>100mm时，纵横方向的弯曲允许偏差小于10mm。全长在25mm以上时，横向弯曲允许[偏差小于25mm。多条平行管段在同一平面上，间距允许偏差3m。支吊架不得设在焊缝处，应距焊缝不小于50-100mm施焊时要注意清理吹进管内的氧化铁熔渣以免堵塞管道。 Steel pipe welding: There should be no vertical and horizontal cracks, pores and slag inclusions at the weld; there should be no residue, pits and obvious weld nodules on the inner and outer surfaces of the pipe. It is usually tested by hydraulic pressure, and the test pressure is 1.25-1.5 times the engineering pressure. It is required to be inspected under the specified test pressure. It is qualified if there is no water seepage or leakage. The size of the reserved hole for the pipe to pass through the foundation of the building is generally about 2 times larger than the pipe diameter, and a sleeve is added. The sleeve is filled with insulation material. If it passes through the floor, the upper end of the sleeve should be 20mm above the ground to prevent the ground water of the upper room from seeping into the lower room, and the lower end is flush with the bottom of the floor. Pipe supports can be divided into three types according to the structural form: brackets, hangers and pipe clamps. The first two types of horizontal pipes are mostly manufactured on site, and the pipe clamps can be purchased to fix the risers. Generally, the net distance between the main pipe and the wall or column surface is not less than 60mm, and the net distance between the branch pipe and the wall is 30mm. All reserved holes and the wall where the brackets are buried should be filled and blocked after the pipeline is installed and before the decoration project is completed. After the pipeline is connected, it is necessary to ensure that on the 10m pipe clamp, when the diameter d<100mm, the allowable deviation of the bending in the longitudinal and transverse directions is less than 5mm; when d>100mm, the allowable deviation of the bending in the longitudinal and transverse directions is less than 10mm. When the total length is more than 25mm, the allowable deviation of the transverse bending is less than 25mm. When multiple parallel pipe sections are on the same plane, the allowable deviation of the spacing is 3m. The support and hanger shall not be set at the weld, and shall be no less than 50-100mm away from the weld. When welding, pay attention to cleaning the iron oxide slag blown into the pipe to avoid clogging the pipeline.
