Pombi yeLSAW (Longitudial Submerged Arc Welding)
LSAW (Kukwesha Arc Yakanyudzwa Mumvura Yenguva Yakareba):Izvi zvinoreva maitiro ekugadzira.
Longitudinal: Musono we weld unofamba wakaenzana nehurefu hwepombi (mumutsara wakatwasuka). Izvi zvakasiyana neHSAW/SSAW (Helical/Spiral Submerged Arc Welding), uko weld iri spiral.
Kunyudza Arc Yakanyudzwa Mumvura (SAW): Maitiro ekunyudza emhando yepamusoro apo arc inonyudzwa pasi pechikamu chefusible flux. Izvi zvinobvumira kupisa kwakadzika, zvinogadzira weld yakasimba, yakafanana, uye zvinogadzira kupera kwakatsetseka pasina kupararira.
Musono Wakatwasuka Wakabatana Nemativi Maviri:Izvi zvinotsanangura hunhu hwemuviri hwe weld.
Pombi iyi inogadzirwa kubva mundiro imwe chete yesimbi (skelp) yakakungurutswa kuita sirinda, zvichiita kuti pave nemusono mumwe chete wakatwasuka.
Yakasimwa Pamativi Aviri: Kusunda kunoitwa mukati nekunze kwepombi. Izvi zvakakosha nekuti zvinoita kuti kusunda kuve kwakasimba zvakanyanya, zvichiita kuti ikwanise kubata kumanikidzwa kwakanyanya uye mashandisirwo akaomarara.

Mapombi eSimbi eLSAW Mashandisirwo Akakosha
| Chikamu Chekushandisa | Mashandisirwo Akananga | Nei LSAW Inoshandiswa |
| Mapaipi eOiri neGasi ari Mhenderekedzo/Kunze kweMhenderekedzo | Mapaipi ekufambisa mafuta asina kucheneswa, gasi rechisikigo, uye zvigadzirwa zvakanatswa. | Inobata kumanikidzwa kwakanyanya kwemukati, inodzivirira kumanikidzwa kwekunze, uye inogona kuputirwa kuti idzivirire ngura munzvimbo dzakaoma. |
| Mabasa Ekumanikidzwa Kwakanyanya | Utsi hwemhepo hunomanikidzwa zvakanyanya, nzira dzekudya dzemakemikari, uye kutakurwa kwetsvina. | Kuvakwa kwakasimba kunogona kutsungirira kushushikana kwakasimba nguva dzose pasina kukundikana. |
| Zvivako zveMarine & Kuunganidza | Kuunganidza hwaro hwemabhiriji, zviteshi zvengarava, uye mapuratifomu ekunze kwegungwa. | Madziro makuru neakareba anopa rutsigiro rwakakura rwechivakwa uye anokwanisa kutakura mutoro. Anowanzo rovererwa pasi muvhu. |
| Uinjiniya hweZvekuvaka neKuvaka | Makoronga ezvivakwa zvemarefu, nhandare dzemitambo, uye zvivakwa zvikuru. | Inoshandiswa se "mapombi" akazadzwa nekongiri (CFST) kupa simba guru uye kugadzikana kwechimiro chepakati. |
| Kutapurirana kweMvura | Migero yemvura yakakura uye nzvimbo dzekushandisa magetsi emvura. | Inokwanisa kufambisa huwandu hwakawanda hwemvura pasi pekumanikidzwa kwakanyanya. |
Zvitupa zveMapaipi eSimbi eLSAW
- Sisitimu yeHSE yeISO9001&ISO14001&ISO45001.
- API Spec 5L ine Sour service ye linepipe.
- Chiratidzo cheCE chepombi yeEU CPR&PED.
- ISO17025 yerabhoritari.
Rondedzero Yekubvumidzwa Kwemapaipi Esimbi eLSAW
ADNOC neEPC dzakawanda dziri munyika nekunze kwenyika.
Kudzora Hunhu hweMapaipi eSimbi eLSAW
Rabhoritari yedu yakavambwa zvichienderana nezvinodiwa neCNAS neAPI 5L PSL2.
- Kuedzwa kwemakemikari
- Kuyedzwa kwesimba
- Kuyedzwa kweCVN kunokonzerwa nehutachiona kwakanyanya -70°C
- Kuongororwa kweDWT kwakanyanya -60°C
- Kuedzwa kwesimbi
- Kuyedzwa kwekuomarara
- Kuedzwa kwekuputira
Takavaka sisitimu yekutevedza pombi yega yega kubva paplate kuenda papombi yapera nenhamba yepombi uye kuchengetedza rekodhi kwemakore maviri.
Nei Mapaipi eLSAW Achisarudzwa Kuti Ashandiswe Nemhando Yepamusoro
Simba Rakanaka uye Kuongororwa Kwekumanikidzwa:Maitiro eSAW ane mativi maviri anogadzira weld yakasimba sesimbi yesimbi pachayo, kana kuti yakasimba kupfuura simbi yesimbi. Izvi zvinoita kuti ive yakakodzera kushandiswa nemhepo ine simba rakawanda.
Madhayamita Makuru uye Madziro Makobvu:Mapaipi eLSAW anogona kugadzirwa nedhayamita yakakura kwazvo (kazhinji kubva pamasendimita 16 kusvika pamasendimita 60 kana kupfuura) uye nemadziro akakora kwazvo, izvo zvisingaite nemapaipi madiki akaita seERW (Electric Resistance Welding).
Kururama Kwakanaka Kwazvo:Ane saizi dzakafanana uye kutenderera kwakafanana, izvo zvakakosha pakuvaka mapaipi nemapurojekiti ekuvaka.
Yakanakira Kuputira:Musono wavo wakatwasuka uye pamusoro wakatsetseka zvinoita kuti zvinyatsokodzera kuisa machira akasiyana-siyana ekudzivirira (senge FBE Fusion Bonded Epoxy, 3LPE/3LPP) uye machira ekudzivirira (semuenzaniso, machira ekusimbisa ekongiri emapombi ekunze). Nzvimbo yakatsetseka uye yakafanana inoita kuti machira anyatsonamira uye aite basa rawo rekudzivirira.
