Yethula:
Ezweni lamapayipi ensimbi,ipayipi elihlanganisiwe eliyindilingaithandwa ngamandla ayo aphezulu, ukuguquguquka kanye nokusebenza kahle kwezindleko. Lawa mapayipi asetshenziswa kabanzi ezimbonini ezahlukahlukene ezifana nowoyela negesi, ukudluliselwa kwamanzi, ubunjiniyela bezakhiwo kanye nokuthuthukiswa kwengqalasizinda. Ukuqinisekisa ukuhlanganiswa okungenamthungo kanye nokusebenza kahle, kubalulekile ukuqonda imininingwane elawula ipayipi elihlanganisiwe elihlanganisiwe. Kule bhulogi, sizohlola izici ezibalulekile zemininingwane yepayipi elihlanganisiwe elihlanganisiwe, sicacise ubukhulu balo, izinto zokwakha kanye nezidingo ezithile.
1. Usayizi wepayipi:
Amapayipi ahlanganisiwe ajikelezayo atholakala ngobukhulu obuhlukahlukene, okuqinisekisa ukuhambisana namaphrojekthi ahlukene. Ubukhulu buvame ukufaka ububanzi bangaphandle (OD), ubukhulu bodonga (WT), kanye nobude. Ububanzi bangaphandle busukela kumasentimitha angu-20 kuya ku-120 amayintshi, kanti ubukhulu bodonga busukela ku-5 mm kuya ku-25 mm. Ngokuphathelene nobude, izingxenye ezijwayelekile zamapayipi ahlanganisiwe ajikelezayo zingamamitha angu-6, amamitha angu-8, kanye namamitha angu-12 ukuze zivumelane nezidingo ezahlukene zobunjiniyela.
2. Izinto zokwakha:
Ukukhethwa kwezinto zepayipi ze-SSAW kubalulekile futhi kuncike kakhulu ekusetshenzisweni okuhlosiwe kanye nezimo zemvelo. Insimbi yekhabhoni isetshenziswa kabanzi ngenxa yamandla ayo, ukuqina kwayo, kanye nokumelana nokugqwala. Ngaphezu kwalokho, ngezinhlelo ezithile ezidinga ukumelana nokugqwala okuthuthukisiwe noma ukumelana nokushisa okuphezulu, amapayipi enziwe ngensimbi ye-alloy, insimbi engagqwali, noma ezinye izinto ezikhethekile angasetshenziswa.
3. Inqubo yokukhiqiza:
Ipayipi elihlanganisiwe elijikelezayo likhiqizwa ngenqubo yokwakha ejikelezayo eqhubekayo kusetshenziswa ama-coil ensimbi. Le ndlela iqinisekisa ukufana kobukhulu bodonga, ububanzi kanye nobuqotho besakhiwo sonke. Ikhoyili ifakwa emshinini, okuyibumba ibe yisimo esifiselekayo esijikelezayo bese ihlanganisa imiphetho ndawonye. Ubuchwepheshe obuthuthukisiwe obuhilelekile enkambisweni yokukhiqiza buvumela ukulawula okunembile usayizi kanye nokusebenza kwepayipi lokugcina.
4. Izindinganiso zekhwalithi:
Ukuze kuhlangatshezwane nezindinganiso zemboni nokuqinisekisa ukuthembeka kwamapayipi ahlanganisiwe ajikelezayo, kuqalwa izinyathelo ezahlukahlukene zokuqinisekisa ikhwalithi. Lokhu kufaka phakathi ukuhambisana nezindinganiso eziqashelwa emhlabeni wonke njenge-API 5L, i-ASTM A252 kanye ne-ISO 3183-3. Ukuhambisana nalezi zincazelo kuqinisekisa izakhiwo zemishini, ukwakheka kwamakhemikhali, kanye nokunemba kobukhulu bepayipi.
5. Ukuhlolwa nokuhlolwa:
Ukuqinisekisa ubuqotho nokusebenza okuphephile kwepayipi elihlanganisiwe eliyi-spiral, kudingeka izinqubo zokuhlola eziqinile kanye nokuhlola. Sebenzisa izindlela zokuhlola ezingonakalisi njengokuhlolwa kwe-ultrasound, ukuhlolwa kwe-radiographic kanye nokuhlolwa kokungena kombala. Lezi zivivinyo zibona noma yimaphi amaphutha esakhiwo noma ukungahambisani kwezinto okungathinta ukusebenza nokuqina kwepayipi. Ngaphezu kwalokho, izivivinyo zomzimba ezifana nokuhlolwa kwe-hydrostatic zenziwa ukuhlola amandla kanye nomthamo wokuthwala ingcindezi wamapayipi.
Ekuphetheni:
Amapayipi ahlanganisiwe ajikelezayo anikeza izinzuzo eziningi kunezinye izinhlobo zamapayipi futhi imininingwane yawo idlala indima ebalulekile ekugcineni ikhwalithi yawo, ukuthembeka kanye nokuhambisana nezinhlelo zokusebenza ezahlukene. Ukuqonda ubukhulu, izinto zokwakha, izinqubo zokukhiqiza kanye namazinga ekhwalithi ahlobene nepayipi elihlanganisiwe elijikelezayo kubalulekile ekuqinisekiseni ukusebenza kahle kanye nesisombululo esingabizi kakhulu. Njengoba ubuchwepheshe buqhubeka nokuthuthuka, imininingwane elawula la mapayipi iyaqhubeka nokuthuthuka, okwandisa ukusebenza kahle kwawo kanye nokuguquguquka kwawo ezimbonini ezahlukene. Ngokucabangela le mininingwane, onjiniyela kanye nochwepheshe bangenza izinqumo ezinolwazi mayelana nokukhetha kanye nokusetshenziswa kwepayipi elihlanganisiwe elijikelezayo kumaphrojekthi abo.
