Insimbi engagqwali isetshenziswa kakhulu ezimbonini eziningi ngenxa yokumelana nokugqwala okuhle kakhulu, ukuqina nobuhle bayo. Iza ngezindlela eziningi, okuhlanganisa amapayipi namashubhu asetshenziselwa izinhloso ezahlukene. Kulesi sihloko, sizobheka kabanzi umhlaba wamapayipi ensimbi engagqwali futhi sigxile emehlukweni phakathi kwamapayipi ensimbi angenamthungo nangenasici.
Okokuqala, kubalulekile ukuqonda umehluko phakathi kwamapayipi namashubhu. Nakuba la magama evame ukusetshenziswa ngokushintshana, anezici ezithile eziwahlukanisayo. Amapayipi, ngokuvamile akalwa ngobubanzi bawo bangaphakathi (ID), aklanyelwe ukuthutha uketshezi noma amagesi ngendlela efanele. Ngokuphambene, ipayipi likalwa ngedayamitha yangaphandle (OD) futhi ngokuvamile lisetshenziswa ezinhlelweni zokusebenza noma izinjongo zokudlulisa.
Manje, ake singene sijuleamapayipi ensimbi engenamthungo. Njengoba igama liphakamisa, ipayipi elingenamthungo alinawo amashisela ngobude bepayipi. Akhiqizwa ngokubhoboza insimbi engagqwali engenalutho engenalutho futhi ayikhiphe ku-mandrel ukuze kwakheke umumo nosayizi oyifunayo. Le nqubo yokukhiqiza iqeda isidingo sokushisela, ngaleyo ndlela ikhulise amandla e-tube nokumelana nokucindezela.
Amapayipi ensimbi engenamthungobanezinhlobonhlobo zezimfanelo eziphakeme. Okokuqala, azinayo i-seams, iqinisekisa izindawo zangaphakathi ezibushelelezi nezingaguquguquki, zinciphisa ingozi yokugqwala nokuguguleka. Lesi sici sibaluleke kakhulu ezinhlelweni zokusebenza lapho imidiya edluliswayo ingase yonale indawo futhi ibeke engcupheni ubuqotho bepayipi. Okwesibili, ipayipi elingenamthungo linamandla aphezulu okuqinile kunepayipi elishiselwe, okulenza libe lilungele izinhlelo zokusebenza ezidinga ubuqotho obuthuthukisiwe besakhiwo nokuqina. Ngaphezu kwalokho, ukuntuleka kwama-welds kunciphisa amathuba okuvuza noma ukwehluleka, ukunikeza ipayipi lensimbi engenamthungo inzuzo ezimbonini ezibucayi ezifana nowoyela negesi noma izitshalo zokucubungula amakhemikhali.
Ngakolunye uhlangothi, amapayipi ensimbi engagqwali angaba ashiselwe noma angenamthungo. Ipayipi lensimbi engagqwali elishiselwe lenziwa ngokugoqa i-strip yensimbi engagqwali ibe yisimo esiyicylindrical kanye nokushisela imithungo. Le nqubo yokushisela, nakuba isebenza kahle futhi ingabizi, ibangela izindawo ezibuthakathaka emthungoni, okwenza ipayipi kube lula ukuvuza, ukugqwala nokukhathala. Kodwa-ke, ipayipi elishiselwe lisafanele ukusetshenziswa okungafunwa kakhulu, njengamapayipi noma amasistimu okunisela, lapho ingcindezi kanye nokugqwala kwemithombo yezindaba edluliswayo iphansi kakhulu.
Sengiphetha, umehluko omkhulu phakathi kwepayipi lensimbi engenamthungo kanye nepayipi lensimbi engagqwali inqubo yabo yokukhiqiza kanye nokusetshenziswa okuhlosiwe. Akhiqizwe ngaphandle kokushisela futhi akalwa ngobubanzi bangaphandle, amapayipi angenamthungo anikeza amandla aphakeme, ukumelana nokugqwala nokwethembeka, okuwenza abaluleke kakhulu ezimbonini ezibucayi. Ngakolunye uhlangothi, ipayipi lensimbi engagqwali, kungakhathaliseki ukuthi lishiselwe noma alinamthungo, ngokuvamile lisetshenziswa ezinhlelweni ezingadingeki kangako lapho ukuphumelela kwezindleko kuthatha indawo yokuqala ngaphezu kwamazinga aphezulu okuqina nobuqotho. Uma ukhetha ipayipi nepayipi elingenamthungo, kubalulekile ukucabangela izidingo ezithile zesicelo esihlosiwe futhi uxhumane nochwepheshe bemboni ukuqinisekisa ukuthi ukhetho olufanele kakhulu luyenziwa.
