I-LSAW (Longitudinal Submerged Arc Welded) ipayipi yensimbi iwuhlobo lwepayipi lensimbi elishiselwe elikhiqizwa kusetshenziswa inqubo yokushisela ye-arc engaphansi kwamanzi.
| Ngaphandle Ububanzi | 325-2020MM |
| Ubukhulu | 7.0-80.0MM (ukubekezelela +/-10-12%) |
| Ubude | 6M-12M |
| Okujwayelekile | I-API 5L, ASTM A553, ASTM A252 |
| Ibanga Lensimbi | Ibanga B, x42, x52 |
| Ipayipi Iyaphela | I-beveled igcina ngokuvikela insimbi noma ngaphandle kwamapayipi |
| I-Pipe Surface | I-Natural Blackor Painted Blackor 3PE Coated |
I-API 5L:Leli zinga libekwe yi-American Petroleum Institute futhi licacisa izidingo zokwenza ipayipi likalayini elisetshenziselwa ukuhambisa uwoyela, igesi, neminye imikhiqizo esekwe kuphethiloli. Ukuhambisana ne-API 5L kuqinisekisa ukuthi ipayipi lensimbi le-LSAW lihlangabezana nekhwalithi edingekayo kanye nenqubo yokusebenza ukuze isetshenziswe embonini kawoyela negesi.
I-ASTM A53:I-ASTM A53 iwukucaciswa okujwayelekile kwepayipi, insimbi, emnyama nokucwiliswa okushisayo, ehlanganiswe nezinc, eshiselwe, futhi engenamthungo. Ukuhambisana ne-ASTM A53 kuqinisekisa ukuthi ipayipi lensimbi le-LSAW lihlangabezana nezidingo ezithile ukuze lisetshenziswe kumishini nezinhlelo zokucindezela, kanye nokusetshenziswa okuvamile.
I-ASTM A252:ukucaciswa okujwayelekile kwezinqwaba zamapayipi ensimbi ashiselwe futhi angenamthungo. Uma kukhulunywa ngamapayipi ensimbi e-LSAW (Longitudinal Submerged Arc Welded), ukuhambisana ne-ASTM A252 kubaluleke kakhulu ezicelweni ezibandakanya izinqwaba zamapayipi ensimbi asetshenziswa ekwakheni nasekusekeleni amaphrojekthi. I-ASTM A252 icacisa izidingo zobuchwepheshe zezinqwaba zamapayipi ensimbi, okuhlanganisa ubukhulu, izakhiwo zemishini, nezinqubo zokuhlola.
Amapayipi ensimbi e-LSAW athobela i-ASTM A252 aklanyelwe ukuhlangabezana nezidingo ezithile ezizosetshenziswa ekunqwabelaniseni izicelo, njengokwakhiwa kwesisekelo, izakhiwo zasolwandle, ukwakhiwa kwebhuloho, namanye amaphrojekthi wobunjiniyela bomphakathi. Ukuhambisana ne-ASTM A252 kuqinisekisa ukuthi amapayipi ensimbi e-LSAW ahlangabezana nekhwalithi edingekayo, ukusebenza, kanye namazinga okuphepha ukuze asetshenziswe okuhlosiwe ekuhlanganiseni izinhlelo zokusebenza.
