Chitoliro chachitsulo cha SAWLndi chitoliro chowotcherera chotalikirapo chomwe chimapangidwa pogwiritsa ntchito njira ya Submerged Arc Welding (SAW).
SAWL = LSAW
Mitundu iwiri yosiyana ya njira yowotcherera imodzimodziyo imatanthawuza mapaipi achitsulo omizidwa kwanthawi yayitali.Izi ndizomwe zimachitika makamaka chifukwa cha zinenero komanso kusiyana kwa madera, koma kwenikweni, zonsezi zimalongosola njira yopangira imodzi.
Njira Zopangira SAWL
Kusankha Mbale ndi Kukonzekera → Kudula ndi Kugaya M'mphepete → Kupanga → Kusoka ndi kuwotcherera kale → Kuwotcherera M'kati ndi Kunja Kwamsoko → Kuyendera Seam Yowotcherera → Kuwongola, Kukulitsa Kuzizira ndi Kudula Kufikira Utali → Chithandizo cha Kutentha → Chithandizo Chapamwamba ndi Chitetezo → Kuyendera Komaliza ndi Kuyika
Kusankha mbale ndi Kukonzekera
Kusankha zinthu zoyenera zitsulo mbale, kawirikawiri mkulu-mphamvu mpweya zitsulo kapena aloyi zitsulo mbale.
Chitsulocho chiyenera kutsukidwa pamwamba kuti chichotse dzimbiri, mafuta, ndi zonyansa zina zisanapangidwe.
Kudula ndi Kugaya M'mphepete
Kudula zitsulo zitsulo: Kudula mbale zachitsulo mpaka kukula kwake molingana ndi kukula kwa chitoliro chachitsulo chopangidwa.
Kupukuta m'mphepete: kugwiritsa ntchito makina ophera m'mphepete, kuchotsa ma burrs ndi mawonekedwe oyenera m'mphepete.
Kupanga
Chitsulo chathyathyathya chimapindika kudzera pamphero kotero kuti pang'onopang'ono amapangidwa kukhala mawonekedwe otseguka a cylindrical.Njira yopangira nthawi zambiri imakhala JCOE.
Kusoka ndi pre-kuwotcherera
Pogwiritsa ntchito seamer yowotcherera isanakwane, msoko, ndi kuwotcherera kusanachitike kumachitika.
Pre-kuwotcherera kumapeto kwa mbale kukonza mawonekedwe ndi kuonetsetsa olondola matako jointing machubu pa ndondomeko kuwotcherera waukulu.
Kuwotcherera Msoko Wamkati ndi Wakunja
Mbali zazitali (zozungulira) za chitoliro zimawotcherera pogwiritsa ntchito njira yowotcherera ya arc.Sitepe nthawi zambiri anachita imodzi mkati ndi kunja kwa chitoliro.
Kuwotcherera kwa arc pansi pamadzi kumachitika m'malo otsekedwa kapena otsekedwa pomwe malo otsekemera amaphimbidwa ndi kuchuluka kwa flux kuti ateteze oxidation ndikusunga weld kukhala woyera.
Welding Seam Inspection
Mukamaliza kuwotcherera, kuwotcherera kumawunikiridwa mowoneka komanso osawononga (mwachitsanzo X-ray kapena kuyezetsa akupanga) kuwonetsetsa kuti kuwotcherera kulibe chilema ndipo kumakwaniritsa miyezo yapamwamba.
Kuwongola, Kukulitsa Kozizira ndi Kudula Mpaka Utali
Pogwiritsa ntchito makina owongola, yongolani chitoliro chachitsulo.Onetsetsani kuti kuwongoka kwa chitoliro chachitsulo kumakwaniritsa zofunikira
Wonjezerani chitoliro chachitsulo kudzera mu makina okulitsa m'mimba mwake kuti mukwaniritse m'mimba mwake ndikuchotsani nkhawa.
Dulani chitoliro chachitsulo muutali wotchulidwa malinga ndi zofuna za makasitomala.
Kutentha Chithandizo
Ngati n'koyenera, machubu ndi kutentha mankhwala, monga normalized kapena annealed, kusintha makina katundu machubu ndi kuonjezera kulimba ndi mphamvu.
Chithandizo cha Pamwamba ndi Chitetezo
Zochizira zokutira, monga zokutira zotsutsana ndi dzimbiri, zimagwiritsidwa ntchito pamwamba pa mapaipi achitsulo kuti apititse patsogolo kukana kwa dzimbiri komanso moyo wautumiki.
Kuyang'anira Komaliza ndi Kuyika
Mukamaliza masitepe onse opangira, kuunika komaliza komanso komaliza kumachitidwa kuti zitsimikizire kuti chinthucho chikukwaniritsa zofunikira.Kuyika bwino kumachitidwa pokonzekera kutumiza.
SAWL Chitsulo Pipe Main Production Equipment
Makina odulira mbale zitsulo, makina opangira zitsulo, makina achitsulo opindika, makina opangira chitoliro chachitsulo, chitoliro chachitsulo chisanachitike makina osokera, makina owotcherera mkati, makina owotcherera akunja, makina ozungulira achitsulo, makina omaliza kuwongola, chamfering mutu wathyathyathya. makina, makina owonjezera.
Zida Zazikulu za SAWL
Chitsulo cha Carbon
Zomwe zimagwiritsidwa ntchito kwambiri pazogwiritsidwa ntchito zambiri.Chitsulo cha kaboni chimasiyanasiyana malinga ndi momwe zilili ndi mpweya wake komanso zinthu zina zophatikizika zomwe zimawonjezeredwa kuti zisinthe mphamvu zake, kulimba kwake, komanso kukana dzimbiri.
Chitsulo chochepa cha alloy
Tizilombo tating'onoting'ono ta alloying (mwachitsanzo, faifi tambala, chromium, molybdenum) amawonjezedwa kuti apititse patsogolo zinthu zinazake, monga kutentha pang'ono kapena kukana kuvala.
Zitsulo Zochepa Zamphamvu Zochepa (HSLA):
Zopangidwa mwapadera za aloyi otsika zimapereka mphamvu zowonjezera komanso kulimba kwinaku zikukhalabe ndi weldability wabwino komanso mawonekedwe.
Chitsulo chosapanga dzimbiri
Amagwiritsidwa ntchito m'malo owononga kwambiri monga subsea kapena malo opangira mankhwala.Machubu achitsulo chosapanga dzimbiri amapereka dzimbiri komanso kukana kutentha kwambiri.

Mawonekedwe Ogwiritsa Ntchito Paipi Yachitsulo ya SAWL
Mkulu wamakina mphamvu ndi kulimba
wokhoza kupirira kupanikizika kwakukulu ndi malo ovuta, oyenera ntchito zomwe zimafuna mphamvu zambiri.
Kulondola kwapamwamba kwambiri
Kupanga molondola kumawonetsetsa kuti m'mimba mwake ndi makulidwe a khoma, ndikuwongolera kudalirika kwapaipi.
Zabwino kuwotcherera khalidwe
Kuwotcherera kwa arc pansi pamadzi kumachepetsa makutidwe ndi okosijeni pansi pa mphamvu yotchinga mpweya ndi kutuluka, kumapangitsa chiyero ndi mphamvu ya weld.
High dzimbiri kukana
mankhwala owonjezera odana ndi dzimbiri amapangitsa kukhala oyenera kumadera osiyanasiyana, kuphatikizapo mapaipi apansi pamadzi kapena pansi pa nthaka.
Zoyenera kuyenda mtunda wautali
Kulimba kwamphamvu komanso kukhazikika kowoneka bwino kumapangitsa kuti ikhale yabwino pamapaipi amafuta ndi gasi akutali.
Mapulogalamu a SAWL Steel Pipe
Ntchito zofunika kwambiri za chitoliro chachitsulo cha SAWL zitha kufotokozedwa mwachidule ngati kugwiritsa ntchito sing'anga ndi zomangamanga.
Kutumiza media
Mipope yachitsulo ya SAWL ndiyoyenera kwambiri kunyamula zinthu monga mafuta, gasi ndi madzi.Chifukwa cha mphamvu zawo zamakina apamwamba komanso kukana kukanikiza kwambiri, mapaipiwa amagwiritsidwa ntchito mtunda wautali pansi pa nthaka kapena mapaipi oyendetsa mafuta ndi gasi pamtunda wautali, komanso m'matauni ndi mafakitale operekera madzi ndi ngalande.
Kugwiritsa ntchito mwamapangidwe
Chitoliro chachitsulo cha SAWL chimapereka mphamvu zofunikira komanso kukhazikika pomanga milatho, zomangamanga zothandizira, nsanja za m'mphepete mwa nyanja, ndi zina zomwe zimafuna mphamvu zambiri komanso kukhazikika.Mapulogalamuwa amagwiritsa ntchito kunyamula katundu wambiri komanso katundu wabwino wowotcherera wa chitoliro chachitsulo.
Zathu Zogwirizana
Monga welded mpweya zitsulo chitoliro wopanga ndi yogulitsa mu China, tadzipereka kupereka makasitomala athu mankhwala apamwamba ndi utumiki kwambiri.Ngati mukusowa chitsulo chitoliro kapena mankhwala okhudzana, chonde omasuka kulankhula nafe.Tikuyembekezera kulandira kufunsa kwanu ndikukupatsani mayankho okhutiritsa.
