Welded zitsulo chitolirondi chitoliro chachitsulo chomwe m'mphepete mwa mbale zachitsulo kapena ma coil amawotcherera mu mawonekedwe a cylindrical. Malinga ndi njira kuwotcherera ndi mawonekedwe, mipope zitsulo welded akhoza kugawidwa m'magulu awa:

Longitudinal welded steel chitoliro (LSAW/ERW): Longitudinal welded steel chitoliro ndi chitoliro chachitsulo chomwe m'mphepete mwa mbale zachitsulo kapena ma coils amapinizidwa ndikuwotchedwa molunjika. Chitoliro chachitsulo chotere chimakhala ndi mphamvu zabwino komanso mtengo wotsika mtengo, koma mphamvu yake ndi yotsika pang'ono kuposa chitoliro chachitsulo chopangidwa ndi chitsulo chofanana.

Spiral Welded Steel Pipe (SSAW): Spiral welded steel chitoliro ndi chitoliro chachitsulo chomwe Mzere wachitsulo umakulungidwa mu silinda ndikuwotchedwa munjira ya helical. Chitoliro chachitsulo chamtunduwu chimakhala ndi mphamvu zambiri, koma mtengo wake ndi wokwera pang'ono.

Ntchito zazikulu za welded zitsulo mapaipi ndi motere:

Mapaipi otumiza: Mapaipi achitsulo opangidwa ndi welded amagwiritsidwa ntchito kwambiri kunyamula mafuta, gasi, gasi, madzi ndi madzi ena, makamaka pamagasi akumatauni ndi makina operekera madzi.

Chitoliro cha Structural: Mapaipi achitsulo opangidwa ndi welded amagwiritsidwa ntchito m'magawo a uinjiniya monga zomanga, milatho, mafelemu achitsulo, ndi zothandizira. Amakhala ndi mphamvu yabwino yonyamula komanso kukana kugwedezeka.
Kupanga makina: Mipope yachitsulo yonyezimira imatha kugwiritsidwa ntchito popanga magawo osiyanasiyana amakina, monga ma shafts, mabulaketi, ma conveyor rollers, etc.

Kubowola mafuta ndi gasi: Mapaipi achitsulo opangidwa ndi welded amatha kugwiritsidwa ntchito popanga pobowola mafuta ndi gasi komanso zida zopangira mafuta, monga mapaipi obowola, ma casings, ndi zina zambiri.
Kupanga nsanja: Mipope yachitsulo yowotcherera imagwiritsidwa ntchito popanga nsanja zoulutsira mawu komanso zolumikizirana.

Greenhouses: mipope zitsulo welded amagwiritsidwa ntchito popanga zogwiriziza kwa greenhouses chifukwa mtengo wawo wotsika ndi mphamvu bwino.
Kupanga njinga zamoto ndi njinga zamoto: Mapaipi achitsulo osongoka amagwiritsidwa ntchito popanga mafelemu anjinga ndi njinga zamoto.

Kupanga mipando: Mipope yachitsulo yowotcherera imatha kugwiritsidwa ntchito kupanga mipando yosiyanasiyana monga mafelemu a bedi, mashelufu a mabuku, mipando, ndi zina.

Mwachidule, mapaipi achitsulo opangidwa ndi zitsulo ali ndi ntchito zambiri, ndipo ntchito zawo zimadalira mtundu, ndondomeko ndi zinthu za chitoliro chachitsulo. Posankha welded zitsulo mapaipi, yoyenera zitsulo chitoliro mtundu ayenera kutsimikiziridwa malinga ndi zosowa zenizeni ndi chilengedwe uinjiniya. Panthawi imodzimodziyo, kuyika, kugwiritsa ntchito ndi kukonza mapaipi achitsulo ndizinthu zazikulu zomwe zimakhudza ntchito yawo ndi moyo wautumiki, ndipo zofunikira ndi zofunikira ziyenera kutsatiridwa.
