1. Khetha indlela yokuxhuma efanele ngokusho kobubanzi nezimo ezithile zepayipi.
①I-Welding: Ukufakwa kuzoqala ngesikhathi esifanele ngokuya ngenqubekelaphambili esizeni. Lungisa amabakaki kusenesikhathi, dweba umdwebo ngokosayizi wangempela, bese wenza amapayipi kusengaphambili ukuze unciphise ukufakwa kanye nokushisela amalunga afile emapayipini. Amapayipi kufanele aqondiswe kusengaphambili, futhi ukuvula kufanele kuvalwe lapho ukufakwa kuphazamiseka. Uma umklamo udinga i-casing, i-casing kufanele yengezwe phakathi nenqubo yokufaka. Ngokwezidingo zomklamo kanye nemishini, gcina isixhumi esibonakalayo, usivale, futhi ulungiselele isinyathelo esilandelayo sokuhlola. Umsebenzi wokucindezeleka.
②Uxhumano olunentambo: Imicu yepayipi icutshungulwa kusetshenziswa umshini wokulutha. Ukuchusha okwenziwa ngesandla kungasetshenziselwa amapayipi angu-1/2″-3/4″. Ngemuva kokuhlanganisa, ukuvuleka kwepayipi kufanele kuhlanzwe futhi kugcinwe bushelelezi. Imicu ephukile nemicu engekho akumele idlule u-10% yenani eliphelele lemicu. Ukuxhuma kufanele kuqine, kungabi khona ilinti eveziwe empandeni. Intambo eveziwe ezimpandeni akufanele ibe ngaphezu kwama-buckles angu-2-3, futhi ingxenye eveziwe yentambo kufanele ibe yi-anti-corrosion kahle.
③Ukuxhumeka kwe-Flange: Kudingeka ukuxhumana kwe-Flange ekuxhumekeni phakathi kwamapayipi namavalvu. Ama-flange angahlukaniswa abe ama-flange welding flat, ama-flange welding we-butt, njll. Ama-flanges enziwe ngemikhiqizo ephelile. Umugqa ophakathi we-flange kanye nepayipi kukhona i-perpendicular, futhi ukuvuleka kwepayipi akufanele kuphume endaweni yokuvala i-flange. Amabhawodi afaka i-flange kufanele axutshwe ngamafutha okugcoba ngaphambi kokusetshenziswa. Kufanele bawele ngokulinganayo futhi baqiniswe izikhathi ezingu-2-3. Ubude obuveziwe besikulufu akumele budlule u-1/2 wobubanzi besikulufu. Amantongomane kufanele abe ohlangothini olufanayo. I-gasket ye-flange akufanele iphumele epayipini. , akumele kube khona iphedi ethambekele noma amaphedi angaphezu kwamabili phakathi kwe-flange.

2. I-Anti-corrosion: Amapayipi akhanyisiwe adaluliwe kufanele apendwe ngamajazi amabili empushana esiliva, futhi amapayipi afihliwe afakwe uthayela kufanele apendwe ngamajazi amabili etiyela.

3. Ngaphambi kokubeka nokufaka amapayipi, ukungcola kwangaphakathi kufanele kuhlanzwe ukuze kuvinjwe i-welding slag kanye nolunye udoti ukuba lungangeni emapayipini. Amapayipi afakiwe kufanele aboshwe futhi avalwe.

4. Ngemva kokuqedwa kokwakhiwa, lonke uhlelo kufanele luhlolwe ingcindezi ye-hydrostatic. Ingcindezi yengxenye yokuphakelwa kwamanzi asekhaya ingu-0.6mpa. Uma ingcindezi ingekho ngaphezu kuka-20kpa phakathi nemizuzu emihlanu, iyafaneleka.
