英语
中文简体There are many connection metho門裡ds for stainless steel pipe 笑懂fittings, the mainstream one朋光s are press connection, ri睡術ng pressure connection, flange 冷區connection, groove connect的路ion, welding connection and tape信器r thread connection. They have thei動呢r own advantages and disadvanta機些ges, and it is necessa來資ry to find a suitable 如個method in the actual situation.
Press-fit connection
The connection principle of this method這高 is to use hydraulic pliers鐵樂 to clamp the stainless近睡 steel pipe fittings 錯小on the pipe, and at the sa睡拿me time use an O-ring to achieve th遠湖e water-stop effect, so as 遠房to have a connection effect. Although t來可his method is easy to o報答perate, the pipe wall is very thin, 和小the connection strength is only about 輛理one-third of the pipe body錢我, and the pipe cannot校是 be disassembled. It is easy to我有 leak.
Ring pressure connection
The principle of ring pressure co南地nnection is to use hydraulic pliers有文 to clamp the stainl技森ess steel pipe fittings on the pipe, a請愛nd use a wide band rubber sea新謝ling ring to stop the wate家書r, so as to achieve a good connection 音一effect. Because this method就筆 has one more pressing pit than the p文機ressing type, the connection strength什高 is slightly stronger than that of t花能he pressing type. In ad場技dition, because the p議和ressing pit is annular, the t厭舞ube is easy to rotate, 匠但which will affect the overal個刀l sealing effect.
Flange connection
The principle of flange connection is 刀小to use tightening bolts to c聽她onnect two connectors with flange she答得ets, and then seal the plane sealing理厭 sheets to achieve the cor來照responding connection effect. The 美通advantage is that the co木現nnection strength is high qual快去ity and stable, and the installation is到相 easy and detachable, but the disadvant長農age is that the cost of the f歌地lange is relatively high.
Groove connection
The principle of this method is to use們長 the tightening nut of the pipe fitti金兒ng, press the stainless我道 steel pipe and the pipe fitting with 做船the convex ring axially, and th來校en use the conical sealing ring to sto明見p the water, so as to achieve 房時the connection effect. Th工錢e advantage is that it can 又地be disassembled, but the disadvantag請身e is that the process of rolling th玩北e concave ring at the pipe end is 銀笑added during the installation上了 process, the cost of the cast cl中她amp is relatively high, and it can明筆not be used in pipelines with negative 金生pressure.
Solder connection
The connection principle of this method影身 is to directly weld the two c妹近onnectors through a hot-melting pr就明ocess to achieve the connectio唱樹n. The advantage is that the connect秒醫ion strength is high, but the disa廠短dvantage is that the gas prot做票ection of the welding 月多seam of the field welding port is d這了ifficult to meet the stan年區dard, and the welding seam i民北s easy to rust, which will reduce the人件 service life of the pipeline, and th年些e installation quality largel農兒y depends on the skill of the welder.制很 level, so the quality stability 南校is not high.
Cone and thread connecti自費on
The connection principle of this meth用都od is to directly ti綠湖ghten the stainless steel pip這農e fittings, tighten the月雨 two connecting pieces of th時唱e inner and outer inte你讀rfaces with conical pipe thre金坐ads, and use the pressure of t可舞he connection thread又員 to achieve the sealing effect,商大 thereby completing the 人舊connection. The advantages are t有還hat it is easy to disassemble, 就書the strength of the connection por紅熱t reaches the strength of the pipe body姐高, the installation is convenient and s體數imple, the quality is reliable員但 and stable, and the wall o門訊f the pipe fittings is thin, resultin睡木g in low cost. If the liquid raw白票 material tape is used, it can b到見asically ensure that the interf場家ace will not leak water for a飛為 long time.
