Yethula:

Ukubaluleka kweipayipi lensimbi yekhabhoni elihlanganisiwe eliyindilingaAkunakwenqatshwa lapho kukhethwa ipayipi elifanele ukusetshenziswa kwezimboni ezahlukahlukene. Lawa mapayipi aziwa ngamandla awo aphezulu nokuqina, asetshenziswa kabanzi ekuthuthweni kukawoyela negesi, ezitshalweni zokuhlanza amanzi, kumaphrojekthi okwakha, nokuningi. Sizohlola izici zobuchwepheshe zepayipi lensimbi yekhabhoni elihlanganisiwe eliyi-spiral, sigxile kakhulu enkambisweni yalo yokushisela kanye nemininingwane.

Ukushisela Okujikelezayo: Ukubuka Konke

Amapayipi ensimbi yekhabhoni ahlanganisiwe akhiqizwa ngenqubo yokushisela ejikelezayo, ehilela ukugoqa nokushisela imichilo yensimbi eqhubekayo ibe yisimo esiyindilinga. Le nqubo iyathandwa ngoba iqinisekisa ukujiya okufanayo kulo lonke ipayipi. Indlela yokushisela ejikelezayo inikeza izinzuzo eziningi, kufaka phakathi amandla athuthukisiwe, ukumelana okukhulu nokucindezeleka, kanye namakhono okuphatha umthwalo ngempumelelo. Ngaphezu kwalokho, ingakhiqiza amapayipi ngobukhulu obuhlukahlukene, okwenza afaneleke ezinhlotsheni eziningi zokusebenza.

Ubuchwepheshe bokushisela amashubhu ekhabhoni:

Ukushisela ipayipi lekhabhonikuyisici esibalulekile senqubo yokukhiqiza njengoba iqinisekisa ukuxhumana okuqinile nokuthembekile phakathi kwamashubhu.

- Ukushisela kwe-arc okucwiliswe emanzini (i-SAW): Lobu buchwepheshe busebenzisa i-electrode eqhutshwa njalo ecwiliswe ku-granular flux. Inesivinini esikhulu sokushisela kanye nokungena okuhle kakhulu, okufanelekela amapayipi amakhulu.

- Ukushisela i-Gas Metal Arc (GMAW/MIG): I-GMAW isebenzisa ucingo lokushisela kanye negesi yokuvikela ukukhiqiza ukushisa kokushisela. Ibhekwa njengeguquguqukayo kakhulu futhi ifanele amapayipi anobukhulu obuhlukahlukene.

- Ukushisela i-arc ye-tungsten yegesi (GTAW/TIG): I-GTAW isebenzisa ama-electrode e-tungsten angasetshenziswa kanye negesi yokuvikela. Inikeza ukulawula okunembile kwenqubo yokushisela futhi ivame ukusetshenziselwa ukushisela kwekhwalithi ephezulu kumapayipi amancane.

Ukuqinisekisa ukuhambisana kwamapayipi ensimbi yekhabhoni ahlanganisiwe nge-spiral ezinhlotsheni ezahlukene zokusebenza, akhiqizwa ngokwezindinganiso ezithile zemboni kanye nemininingwane. Imininingwane evelele ifaka:

1. I-API 5L: Imininingwane ye-American Petroleum Institute (API) iqinisekisa ikhwalithi nokuqina kwamapayipi asetshenziselwa ukuthutha igesi, uwoyela, namanzi embonini kawoyela negesi.

2. I-ASTM A53: Le ncazelo ihlanganisa ipayipi lensimbi elimnyama nelishisayo elihlanganisiwe elingenamthungo nelihlanganisiwe lezinhlelo zokusebenza ezahlukahlukene okuhlanganisa ukuthuthwa kwamanzi, igesi, kanye nomusi.

3. I-ASTM A252: Le ncazelo isebenza kumapayipi ensimbi ahlanganisiwe futhi angenamthungo ngezinjongo zokufaka inqwaba ukuze kunikezwe ukwesekwa kwesakhiwo okudingekayo kumaphrojekthi obunjiniyela bezokwakha njengezisekelo zokwakha kanye nokwakhiwa kwamabhuloho.

4. EN10217-1/EN10217-2: Izindinganiso zaseYurophu zimboza amapayipi ensimbi ahlanganisiwe okucindezela kanye namapayipi ensimbi angewona angxubevange wezinhlelo zokuthutha amapayipi ngokulandelana.

Ekuphetheni:

Ipayipi lensimbi yekhabhoni elihlanganisiwe elihlanganisiwe elihlanganisiwe seliyinto ebalulekile kakhulu ezinhlotsheni eziningi zezimboni ngenxa yamandla alo aphezulu kanye nokuqina kwalo. Ukuqonda imininingwane yobuchwepheshe kanye namasu okunamathisela ahilelekile kubalulekile ekukhetheni ipayipi elifanele lephrojekthi ethile. Ngokunamathela ezindinganisweni zemboni eziqashelwayo, ungaqiniseka ngekhwalithi, ukuthembeka kanye nobude besikhathi sala mapayipi. Kungakhathaliseki ukuthi ukuthuthwa kukawoyela negesi, izitshalo zokuhlanza amanzi noma amaphrojekthi okwakha, ipayipi lensimbi yekhabhoni elihlanganisiwe elihlanganisiwe linikeza ikhambi elithembekile lazo zonke izidingo zakho zamapayipi.
