Kuyambira zaka za m'ma 1930, ndi chitukuko chofulumira cha kupanga kwapamwamba kwambiri kwa mizere yowotcherera ndi kupititsa patsogolo luso la kuwotcherera ndi kuyang'anitsitsa, khalidwe la ma welds lakhala likuyenda bwino, ndipo mitundu yosiyanasiyana ya mipope yazitsulo yakhala ikuwonjezeka.Sokani chitoliro chachitsulo.Welded zitsulo mipope anawagawa mowongoka msoko mipope welded ndi kozungulira welded mapaipi malinga ndi mawonekedwe a welds.Gulu ndi njira kupanga: ndondomeko gulu-arc welded chitoliro, kukana welded chitoliro, (high frequency, otsika pafupipafupi) mpweya welded chitoliro, ng'anjo welded chitoliro.
Mapaipi ang'onoang'ono ang'onoang'ono amawotcherera ndi msoko wowongoka, pomwe mipope yayikulu yowotcherera m'mimba mwake nthawi zambiri imakhala yozungulira.Malingana ndi mawonekedwe a mapeto a chitoliro chachitsulo, amagawidwa mu chitoliro chozungulira chozungulira ndi chowoneka bwino (makona, amakona anayi, etc.) chitoliro;malinga ndi zipangizo zosiyanasiyana ndi ntchito, lagawidwa mu migodi madzimadzi Kutumiza mipope welded zitsulo, kanasonkhezereka welded zitsulo mapaipi otsika-anzanu madzimadzi kufalitsa, magetsi welded zitsulo mipope kwa lamba conveyor odzigudubuza, etc. Malinga ndi tebulo kukula mu muyezo dziko panopa , sinthani ndi mainchesi akunja * makulidwe a khoma kuyambira laling'ono kupita lalikulu.
Zomwe zimagwiritsidwa ntchito pamapaipi opangidwa ndi welded ndi: Q235A, Q235C, Q235B, 16Mn, 20 #, Q345, L245, L290, X42, X46, X60, X80, 0Cr13, 1Cr17, 00Cr19Nir19Nir11Cr11, etc.
Zosowa zomwe zimagwiritsidwa ntchito pamapaipi azitsulo ndi zitsulo zachitsulo kapena zitsulo, zomwe zimagawidwa m'mapaipi otenthedwa ndi ng'anjo, mapaipi amagetsi (kukaniza welded) ndi mipope yowotcherera ya arc chifukwa cha njira zawo zowotcherera.Chifukwa cha mitundu yosiyanasiyana yowotcherera, imatha kugawidwa m'mitundu iwiri:
molunjika msoko welded chitoliro ndi ozungulira welded chitoliro.Chifukwa cha mawonekedwe ake omaliza, amagawidwa mu chitoliro chozungulira chozungulira komanso chopangidwa mwapadera (mabwalo, lathyathyathya, etc.) welded chitoliro.Mapaipi owotcherera amagawidwa m'mitundu yotsatirayi chifukwa cha zida zawo zosiyanasiyana komanso ntchito:
GB/T3091-2008 (Mapaipi achitsulo otenthetsera pamayendedwe otsika amadzimadzi): Amagwiritsidwa ntchito kwambiri kunyamula madzi, gasi, mpweya, mafuta, kutenthetsa madzi kapena nthunzi ndi madzi ena omwe amakhala otsika kwambiri ndi zolinga zina.Zoyimira zake ndi: Q235A kalasi yachitsulo.
GB/T14291-2006 (Welded Steel Pipe for Mining Fluid Transport): Amagwiritsidwa ntchito kwambiri pamapaipi achitsulo owongoka owongoleredwa amphamvu ya mpweya, ngalande, ndi mpweya wotulutsa shaft.Zoyimira zake ndi Q235A, Gulu B zitsulo.
GB/T12770-2002 (Stainless steel welded steel pipe for mechanical structure): Amagwiritsidwa ntchito makamaka pamakina, magalimoto, njinga, mipando, zokongoletsera hotelo ndi malo odyera ndi zida zina zamakina ndi zida zamapangidwe.Zoyimira zake ndi 0Cr13, 1Cr17, 00Cr19Ni11, 1Cr18Ni9, 0Cr18Ni11Nb, etc.
GB/T12771-1991 (Chitsulo chosapanga dzimbiri chowotcherera chitoliro choyendera madzimadzi): Amagwiritsidwa ntchito kwambiri kunyamula zotengera zowononga zocheperako.Zida zoyimilira ndi 0Cr13, 0Cr19Ni9, 00Cr19Ni11, 00Cr17, 0Cr18Ni11Nb, 0017Cr17Ni14Mo2, etc.
Komanso welded mipope zosapanga dzimbiri zokongoletsa (GB/T 18705-2002), zitsulo zosapanga dzimbiri mipope yokongoletsa zomangamanga (JG/T 3030-1995), ndi mipope zitsulo welded kwa exchangers kutentha (YB4103-2000).
Longitudinal welded chitoliro ali ndondomeko yosavuta kupanga, mkulu kupanga dzuwa, mtengo wotsika ndi chitukuko mofulumira.Mphamvu ya mipope yowotcherera yozungulira nthawi zambiri imakhala yayikulu kuposa mipope yowongoka yowotcherera.Chopanda kanthu chocheperako chingagwiritsidwe ntchito kupanga mapaipi owotcherera okhala ndi mainchesi akulu a chitoliro, ndipo billet yokhala ndi m'lifupi mwake ingagwiritsidwenso ntchito kupanga mapaipi owotcherera okhala ndi ma diameter osiyanasiyana.Koma poyerekeza ndi chitoliro chowongoka cha kutalika komweko, kutalika kwa weld kumawonjezeka ndi 30-100%, ndipo liwiro lopanga ndilotsika.
Mapaipi akulu akulu kapena okhuthala nthawi zambiri amapangidwa mwachindunji kuchokera ku zitsulo, pomwe mapaipi ang'onoang'ono owotcherera ndi mapaipi opyapyala amangofunika kuwotcherera mwachindunji kudzera muzitsulo zachitsulo.Ndiye mutatha kupukuta kosavuta, kujambula kuli bwino.
Chowonjezera: Chitoliro chowotcherera ndi chowotcherera ndi chitsulo chamizere, motero sichikhala chokwera ngati chitoliro chopanda msoko.
Zogulitsa zimagwiritsidwa ntchito kwambiri mu engineering yamadzi, mafakitale a petrochemical, makampani opanga mankhwala, mafakitale amagetsi, ulimi wothirira, ndi zomangamanga zamatawuni.Ndi imodzi mwazinthu 20 zomwe zapangidwa m'dziko langa.
Amagwiritsidwa ntchito poyendetsa madzi: madzi ndi ngalande.Amagwiritsidwa ntchito poyendetsa gasi: gasi wa malasha, nthunzi, mpweya wamafuta amafuta.
Zolinga zomanga: monga mipope yowunjika ndi milatho;mapaipi amadoko, misewu, ndi zomangira.
