Chitoliro cha LSAWndi chitoliro chachitsulo cholumikizidwa mozungulira chomwe chimapangidwa pogwiritsa ntchito ukadaulo wolumikizira wa arc pansi pamadzi.
Mapaipi achitsulo a LSAW amadziwika ndi ma weld a longitudinal omwe amathamanga kutalika konse kwa chitoliro, omwe amatuluka kuchokera mkati ndi kunja kwa chitoliro.
Ubwino wa chitoliro chachitsulo cha LSAW ndichakuti chimatha kupereka mapaipi akuluakulu, okhala ndi makoma okhuthala, komanso amphamvu kwambiri.

| Ubwino | Fakitale ya Mapaipi a Chitsulo cha LSAW ndi Wopanga; ogulitsa mapaipi achitsulo a LSAW; Ogulitsa mapaipi achitsulo a LSAW; Kugulitsa mwachindunji m'fakitale, kutsimikizika kwa khalidwe, komanso mitengo yotsika mtengo. |
Mwachidule,LSAWNjira yopangira zinthu imaphatikizapo kupotoza mbale zachitsulo kukhala ngati chubu kenako kugwiritsa ntchito welding ya arc yonyowa pansi kuti ilumikize m'mphepete mwa mbale zachitsulo pamodzi kuti ipange chitoliro chachitsulo.
Kenako, tidzakuphunzitsani njira zofunika kwambiri zopangira mapaipi achitsulo a LSAW, zomwe zingakuthandizeni kumvetsetsa bwino momwe ntchitoyi ikuyendera.
1. Kuyang'anira ndi kudula mbale: Kutengera ndi miyezo yogwiritsira ntchito chitoliro chachitsulo ndi miyeso yofunikira, mbale zoyenera zidzadulidwa m'makulidwe oyenera.
2. Kupera m'mphepete: Konzani m'mphepete mwa chitoliro chachitsulo kuti mupange mawonekedwe oyenera kuwotcherera, monga mawonekedwe a V. Gawoli ndi lofunika kwambiri pa ubwino wa chowotcherera.
3. KupangaKampani yathu imagwiritsa ntchito njira yopangira JCOE, momwe mbale yachitsulo imapangidwa kukhala chomangira chopitilira ndi ma rollers ndi makina osindikizira.
4.kuwotcherera: Mu msoko wautali wa kapangidwe ka tubular, kuwotcherera kwa arc pansi pa nthaka kumachitika kuti agwirizane m'mphepete mwa mbale zachitsulo kuti apange chitoliro chachitsulo. Ili ndiye gawo lofunika kwambiri pa ndondomeko yonseyi.
5. Kuyendera: Kuyang'anira zinthu zingapo, kuphatikizapo kuyesa kosawononga 100% komanso kuyesa kutayikira kwa mapaipi achitsulo pogwiritsa ntchito hydrostatic leak, kumatsimikizira kuti chinthu chomalizidwa chikukwaniritsa zofunikira zonse.
Mu njira yeniyeni yopangira mapaipi achitsulo a LSAW, kuwonjezera pa njira zofunika zomwe zatchulidwa pamwambapa, palinso njira zina zambiri zabwino komanso zovuta. Njirazi zimafuna kuwongolera kolondola komanso kuyang'anira bwino khalidwe kuti zitsimikizire kuti mapaipi achitsulo a LSAW apamwamba kwambiri omwe akukwaniritsa miyezo.
1. Yosinthika kwambiriMapaipi achitsulo a LSAW nthawi zambiri amagwiritsidwa ntchito m'malo ogwirira ntchito otentha kwambiri komanso opanikizika kwambiri. Ndi utoto woyenera, mapaipi awa amatha kugwira ntchito bwino ngakhale m'malo otentha kwambiri komanso m'malo ovuta kwambiri.
2. Ubwino wa kuwotcherera: Pakupanga LSAW,kuwotcherera kwa arc kokhala ndi mbali ziwiri (DSAW)Njirayi imagwiritsidwa ntchito. Njirayi imatsimikizira kuti weld yalowetsedwa kwathunthu, motero imapangitsa kuti weld ikhale yabwino kwambiri. Weld ndi yofanana komanso yofanana, zomwe zimapangitsa kuti chitoliro chachitsulo chigwire ntchito bwino komanso kudalirika kwake.
3. Chitoliro chachitsulo chachikulu chokhala ndi makoma okhuthala:
| Zidule | Dzina | M'mimba mwake wakunja | Kukhuthala kwa Khoma |
| SSAW (HSAW, SAWH) | Kuwotcherera kwa Arc Yozungulira Yozungulira | 200 - 3500 mm | 5 - 25 mm |
| LSAW (SAWL) | Kuwotcherera kwa Arc Yokhala ndi Madzi a Longitudinal | 350 - 1500 mm | 8 - 80 mm |
| ERW | Kukana Kwamagetsi Kowongoleredwa | 20 - 660 mm | 2 - 20 mm |
| SMLS | Wopanda msoko | 13.1 - 660 mm | 2 - 100 mm |
Monga momwe tikuonera kuchokera ku kuyerekeza kwa kukula kwa kupanga pamwambapa, mapaipi achitsulo a LSAW ali ndi ubwino woonekeratu popanga mapaipi achitsulo okhala ndi makoma akuluakulu, omwe amakwaniritsa zosowa za mapulojekiti akuluakulu komanso ntchito zamafakitale.
4. Amagwiritsidwa ntchito kwambiriMapaipi achitsulo a LSAW amagwiritsidwa ntchito kwambiri potumiza mafuta ndi gasi, uinjiniya wa zomangamanga, kumanga milatho, ndi madera ena omwe amafunikira mapaipi achitsulo amphamvu chifukwa cha mphamvu zawo zapamwamba komanso magwiridwe antchito abwino kwambiri.

Kuwonjezera pa miyezo yodziwika bwino ya mapaipi achitsulo yomwe yatchulidwa pamwambapa, zipangizo ndi muyezo wa mbale yachitsulo, monga SS400, zimakhudzidwanso popanga mapaipi achitsulo pogwiritsa ntchito njira ya LSAW. Sizilembedwa pano.
Malo amkati ndi akunja a mapaipi achitsulo a LSAW nthawi zambiri amakutidwa kuti agwirizane ndi malo osiyanasiyana ogwirira ntchito.
Zophimba izi zitha kukhala zophimba kwakanthawi kapena zophimba zoteteza dzimbiri kwa nthawi yayitali. Mitundu yodziwika bwino ya zophimba ndi mongautoto, kuyika magetsi, 3LPE, FBE,TPEP, phula la epoxy la malasha, ndi zina zotero.
Zophimba izi zimateteza mapaipi achitsulo bwino ku dzimbiri, zimawonjezera nthawi yawo yogwirira ntchito, ndikuwonetsetsa kuti ali olimba komanso odalirika pansi pa mikhalidwe yosiyanasiyana yachilengedwe.
Chitoliro chachitsulo cha LSAW ndi chinthu chofunikira kwambiri m'mafakitale. Kuti chiziyenda bwino m'misika yosiyanasiyana yadziko lonse komanso yachigawo, chitoliro chachitsulo cha LSAW chiyenera kupeza zikalata zingapo zotsimikizira potumiza ndi kutumiza kunja. Zofala kwambiri ndi izi:Satifiketi ya API 5L,Satifiketi ya ISO 9001,ISO 19001 satifiketi, Satifiketi ya ISO 14001,ndi Satifiketi ya ISO 45001.
