LSAW (Longitudinal double submerge arc welding)carbon steel pipendi mtundu waChithunzi cha SAWzopangidwa ndi mbale zachitsulo zomwe zinali zotentha zokulungidwa ndi JCOE kapena UOE kupanga teknoloji.Ukadaulo wa JCOE umayimira mapangidwe ndi mapangidwe omwe amakhudzidwa panthawi yopanga komanso kuwotcherera mkati ndi kunja ndi kukulitsa kuzizira komwe kumachitika pambuyo pakuwotcherera.
Poyerekeza ndi UOELSAW mapaipi achitsulo, LSAW opanga chitoliro ku China akhoza kupanga kukula kwake motere: OD 406 mm - 1620 mm, makulidwe 6.35 mm - 60 mm, chitoliro kutalika 2 m - 18 mamita ndiMtengo wa LSAWkukhala wapamwamba.
- Njira yopanga chitoliro chachitsulo cha LSAW
Mtengo LSAWlalikulu m'mimba mwake zitsulo chitolironjira yopanga ikufotokozedwa m'munsimu:
1. Plate Probe: Izi ntchito kupanga lalikulu m'mimba mwake LSAW olowa atangolowa kupanga mzere amene ali koyamba zonse bolodi akupanga kuyezetsa.
2. Mphero: Makina ogwiritsira ntchito mphero amachita izi kudzera m'mbale ya mphero ya mbali ziwiri kuti akwaniritse zofunikira za mbale m'lifupi ndi mbali zofanana ndi mawonekedwe ndi digiri.
3. Mbali yokhotakhota: Mbali iyi imatheka pogwiritsa ntchito makina okhotakhota pamphepete mwa mbale.Mphepete mwa mbale imayenera kukwaniritsa zofunikira zokhotakhota.
4. Kupanga: Pambuyo pa sitepe yokhotakhota, mu theka loyamba la makina opangira a JCO, pambuyo pa zitsulo zosindikizidwa, amakanikizidwa mu mawonekedwe a "J" pamene mbali ina ya mbale yachitsulo yomweyi imapindika ndikukanikizidwa. mu mawonekedwe a "C", ndiye kutsegula komaliza kumapanga mawonekedwe a "O".
5. Pre-kuwotcherera: Izi ndi kupanga welded chitoliro zitsulo msoko wowongoka atapangidwa ndi ntchito mpweya kuwotcherera msoko (MAG) kwa kuwotcherera mosalekeza.
6. Kuwotcherera mkati: Izi zimachitidwa ndi kuwotcherera kwa mawaya angapo omira (pafupifupi mawaya anayi) mkati mwa chitoliro chachitsulo chowongoka.
7. Kuwotcherera Kunja: Kuwotcherera Kunja ndi kuwotcherera kwa waya wambiri kumatauni kumtunda wakunja wa LSAW zitsulo zowotcherera chitoliro.
8. Akupanga Kuyesa: Kunja ndi mkati mwa molunjika msoko welded zitsulo chitoliro ndi mbali zonse za m'munsi zinthu welded ndi 100% anayendera.
9. X-ray kuyendera: X-ray mafakitale TV kuyendera ikuchitika mkati ndi kunja ntchito chithunzi processing dongosolo kuonetsetsa pali kuzindikira kuzindikira.
10. Kukulitsa: Uku ndi kukwaniritsa kuwotcherera kwa arc pansi pamadzi ndi msoko wowongoka wa chitsulo kutalika kwa dzenje kuti muwongolere kukula kwa chubu chachitsulo ndikuwongolera kufalikira kwa nkhawa mu chubu chachitsulo.
11. Mayeso a Hydraulic: Izi zimachitika pamakina oyesera a hydraulic zitsulo pambuyo pakukulitsa kuyesa kwa muzu kuonetsetsa kuti chitoliro chachitsulo chikukwaniritsa zofunikira ndi makina omwe ali ndi luso lojambulira ndi kusunga.
12. Chamfering: Izi zimaphatikizapo kuyang'anitsitsa komwe kumachitika paipi yachitsulo kumapeto kwa ndondomeko yonse.
