Ipayipi le-LSAWiyipayipi lensimbi elakhiwe ngobude elikhiqizwe kusetshenziswa ubuchwepheshe bokushisela be-arc obungaphansi kwamanzi.
Amapayipi ensimbi e-LSAW abonakala ngokushisela ama-longitudinal agijima bonke ubude bepayipi, aphuma endaweni yangaphakathi nangaphandle yepayipi.
Inzuzo yepayipi yensimbi ye-LSAW ukuthi ingahlinzeka ngamapayipi anobubanzi obukhulu, agqinsile, futhi anomfutho ophezulu.

Ngamagama alula, i-I-LSAWinqubo yokukhiqiza ihilela ukugoqa amapuleti ensimbi abe yisimo seshubhu bese usebenzisa i-arc welding engaphansi kwamanzi ukushisela imiphetho yamapuleti ensimbi ukuze kwakheke ipayipi lensimbi.
Okulandelayo, sizokuthatha ngezinyathelo ezibalulekile ekukhiqizeni amapayipi ensimbi e-LSAW, sikunikeze ukuqonda okucacile kwenqubo.
1. Ukuhlolwa kwepuleti nokusika: Ngokuya ngezindinganiso zokusetshenziswa kwepayipi lensimbi kanye nobukhulu obudingekayo, amapuleti afanelekayo azosikwa abe osayizi abafanele.
2. Ukugaya umphetho: Lungiselela unqenqema lwepayipi lensimbi ukuze wakhe umumo ofanele ukushisela, njengokuma kwe-V.Lesi sinyathelo sibalulekile kwikhwalithi ye-weld.
3. Ukwakha: Inkampani yethu isebenzisa inqubo yokwenza i-JCOE, lapho ipuleti lensimbi lenziwa libe yisakhiwo esiqhubekayo se-tubular ngama-roller kanye nomshini wokunyathelisa.
4.Ukushisela: Kumthungo we-longitudinal wesakhiwo se-tubular, i-arc welding engaphansi kwamanzi yenziwa ukuze kuhlanganiswe imiphetho yamapuleti ensimbi ukuze kwakheke ipayipi lensimbi.Lesi isinyathelo esibucayi kakhulu kuyo yonke inqubo.
5. Ukuhlola: Ukuhlolwa okuningana, okuhlanganisa ukuhlola okungabhubhisi okungu-100% kanye nokuhlolwa kokuvuza kwe-hydrostatic kwamapayipi ensimbi, kuqinisekisa ukuthi umkhiqizo osuphelile uhlangabezana nezidingo ezijwayelekile.
Enkambweni yangempela yokukhiqiza yamapayipi ensimbi ye-LSAW, ngaphezu kwezinqubo ezibalulekile ezishiwo ngenhla, kunezinye izinyathelo eziningi ezinhle neziyinkimbinkimbi.Lezi zinyathelo zidinga ukulawula okunembile kanye nokuqapha kwekhwalithi okuqinile ukuze kuqinisekiswe ukukhiqizwa kwamapayipi ensimbi e-LSAW aphezulu ahlangabezana nezindinganiso.
1. Izimo kakhulu: Amapayipi ensimbi e-LSAW avame ukusetshenziswa ezindaweni ezishisa kakhulu nezinomfutho ophezulu wokusebenza.Ngokugqoka okufanelekile, lawa mapayipi angagcina ukusebenza okuthembekile ngisho nasezimweni ezimbi kakhulu nezimo ze-geological eziyinkimbinkimbi.
2. Ikhwalithi yokushisela: Ekukhiqizeni i-LSAW, iukushisela i-arc engaphansi kwezinhlangothi ezimbili (DSAW)inqubo isetshenziswa.Le nqubo iqinisekisa ukuthi i-weld ingene ngokuphelele, ngaleyo ndlela ifinyelele izinga eliphezulu lekhwalithi yokushisela.I-weld ifana futhi ihambisana, ithuthukisa ngokwengeziwe ukusebenza okuphelele nokuthembeka kwepayipi lensimbi.
3. Ipayipi elikhulu lensimbi eliwugqinsi elinezindonga:
| Izifinyezo | Igama | Ububanzi bangaphandle | Ukuqina Kwezindonga |
| I-SSAW (HSAW, SAWH) | I-Spiral Submerged Arc Welding | 200 - 3500 mm | 5 - 25 mm |
| I-LSAW (SAWL) | I-Longitudinal Submerged Arc Welding | 350 - 1500 mm | 8-80 mm |
| ERW | Ukumelana Kagesi Okushiselwe | 20 - 660 mm | 2 - 20 mm |
| I-SMLS | Ingenamthungo | 13.1 - 660 mm | 2 - 100 mm |
Njengoba kungase kubonakale ekuqhathanisweni kosayizi wokukhiqiza okungenhla, amapayipi ensimbi e-LSAW anezinzuzo ezisobala ekukhiqizeni amapayipi ensimbi anobubanzi obukhulu anodonga olukhulu, ahlangabezana nezidingo zamaphrojekthi amakhulu kanye nezicelo zezimboni.
4. Kusetshenziswa kabanzi: Amapayipi ensimbi e-LSAW asetshenziswa kakhulu ekudlulisweni kwamafutha negesi, ubunjiniyela bezakhiwo, ukwakhiwa kwebhuloho, nezinye izinkambu ezidinga amapayipi ensimbi anamandla amakhulu ngenxa yamandla awo aphezulu nokusebenza okuhle kakhulu.

Ngaphandle kwezindinganiso ezivamile zamapayipi ensimbi ezibalwe ngenhla, izinto kanye nezinga lensimbi yensimbi, njenge-SS400, nazo zihilelekile ekwakhiweni kwamapayipi ensimbi kusetshenziswa inqubo ye-LSAW.Azibaliwe lapha.
Izindawo zangaphakathi nezingaphandle zamapayipi ensimbi ye-LSAW zivame ukumbozwa ukuze zivumelane nezindawo zokusebenza ezihlukene.
Lezi zembatho zingaba izimbobo zesikhashana ezivikelayo noma ezivikela ukugqwala zesikhathi eside.Izinhlobo zokugqoka ezivamile zihlanganisaupende, i-galvanization, I-3LPE, I-FBE,I-TPEP, i-epoxy coal tar, njll.
Lezi zembatho zivikela ngokuphumelelayo amapayipi ensimbi ekugqwaleni, ukwandisa impilo yabo yenkonzo, futhi uqinisekise ukuzinza nokuthembeka kwabo ngaphansi kwezimo ezihlukahlukene zemvelo.
Ipayipi lensimbi ye-LSAW iyinto ebalulekile yezimboni.Ukuze kuqinisekiswe ukuhamba kwawo kahle ezimakethe ezihlukene zikazwelonke nezesifunda, ipayipi lensimbi le-LSAW lidinga ukuthola uchungechunge lwemibhalo yesitifiketi lapho lingenisa futhi lithumela ngaphandle.Ezivamile zihlanganisaIsitifiketi se-API 5L,Isitifiketi se-ISO 9001,ISO 19001 isitifiketi, Isitifiketi se-ISO 14001,futhi Isitifiketi se-ISO 45001.
