Masiku ano, chitoliro chachitsulo chosasunthika chakhala chikugwiritsidwa ntchito kwambiri pazinthu zosiyanasiyana kuphatikiza mapaipi amafuta ndi gasi, petrochemical ndi mafakitale omanga. Amakhulupirira kuti mwina mumakumana ndi chisokonezo pa momwe mungasankhire zitsulo zoyenera pulojekiti yanu. Kapena mutha kukhala ndi nkhawa kuti mungakhale ndi chitoliro chachitsulo chowotcherera kapena chitoliro chopanda chitsulo padziko lapansi.
Monga lamulo, mapaipi achitsulo ndiatali, opanda machubu omwe amagwiritsidwa ntchito pazinthu zosiyanasiyana. Kawirikawiri, amapangidwa ndi njira ziwiri zosiyana zomwe zimabweretsa chitoliro chowotcherera kapena chopanda msoko. Munjira zonse ziwiri, chitsulo chosaphika chimayamba kuponyedwa mu mawonekedwe oyambira ogwirira ntchito. Kenako amapangidwa kukhala chitoliro potambasula chitsulocho kukhala chubu chopanda msoko kapena kukakamiza m'mphepete mwake ndikusindikiza ndi weld. Makamaka, kupanga chitoliro chosasunthika chachitsulo kumayamba ndi billet yolimba, yozungulira yachitsulo. Billet iyi imatenthedwa mpaka kutentha kwambiri ndipo imatambasulidwa ndikukokera pamwamba pa mawonekedwe mpaka itenge mawonekedwe a chubu lopanda kanthu. Monga katswiri wopanga zitoliro zachitsulo ku China, tikufuna kukupatsani zambiri zamtundu uwu wa chitoliro chomwe chimagwiritsidwa ntchito popanga.
Choyamba, mwayi waukulu wa mipope yachitsulo yopanda msoko ndikuwonjezera mphamvu yawo yopirira kukakamizidwa. Malo ofooka kwambiri mu chitoliro chachitsulo chowotcherera ndi msoko wowotcherera. Koma chifukwa chitoliro chachitsulo chosasokonezeka sichinawotchedwe, chimakhalabe ndi msoko, zomwe zimapangitsa kuti chikhale cholimba mozungulira kuzungulira konse kwa chitolirocho. Ndikosavutanso kudziwa kuwerengera kuthamanga popanda kufunidwa kuti muganizire mtundu wa weld. M'malo otsatirawa, ngakhale mtengo wachitsulo wachitsulo nthawi zina umakhala wokwera mtengo kuposa chitoliro chowotcherera. Chifukwa chimodzi, chitoliro chachitsulo chosasunthika ndikutulutsa kosalekeza kwa aloyi, kutanthauza kuti idzakhala ndi gawo lozungulira lomwe mungadalire, lomwe limathandiza mukamayika mapaipi kapena kuwonjezera zopangira. Kuzinthu zina, chitoliro chamtunduwu chimakhala ndi mphamvu zochulukirapo potsitsa. Kulephera kwa mipope ndi kutayikira mu mipope yowotcherera nthawi zambiri kumachitika pa msoko wowotcherera. Koma chifukwa chitoliro chopanda msoko chilibe msoko, sichimakhudzidwa ndi zolepherazo. Pomaliza, phindu lina la mapaipi opanda msoko ndikuti amatha kuchita bwino m'malo ovuta kwambiri, m'malo ozizira kwambiri kapena otentha kwambiri.
Mwachidule, mapaipi ambiri azitsulo ozungulira asanduka zinthu zomwe amakonda kwambiri pamapaipi ambiri azamalonda, kuphatikiza zomanga zombo, mapaipi, zida zamafuta, zida zamafuta, zotengera zokakamiza, zida zamakina ndi zida zam'mphepete mwa nyanja masiku ano. Kutengera zomwe mukufuna kugwiritsa ntchito, mutha kusankha chitoliro choyenera cha polojekiti yanu posachedwa.
