API mild steel pipe imagwiritsidwa ntchito kwambiri m'mafakitale ambiri.Komabe, makasitomala ambiri sakudziwabe kuti ndi mitundu ingati ya chitoliro chachitsulo cha API chomwe chili pamsika.Osadandaula nazo.Nazi tsatanetsatane.

Chitoliro chachitsulo cha API

API mzere zitsulo chitoliro ndi mzere chitoliro kuti akukumana muyezo American Petroleum.Chitoliro cha mzere chimagwiritsidwa ntchito potengera mafuta, gasi ndi madzi kupita kumakampani amafuta ndi gasi.Mapeto a chitoliro amaphatikizapo mapeto omveka, mapeto a ulusi ndi mapeto azitsulo;malumikizidwe awo amamaliza kuwotcherera mapeto, kugwirizana, kugwirizana zitsulo.Ndi chitukuko cha luso, API mzere zitsulo chitoliro osiyanasiyana ntchito ikukula pang'onopang'ono, makamaka lalikulu m'mimba mwake tsoka.Kuphatikizidwa ndi mtengo, welded chitoliro ali ndi udindo waukulu m'munda wa chitoliro mzere, kuchepetsa chitukuko cha zitsulo zosapanga dzimbiri opanda msoko chitoliro.M'chaka cha 2004, kupanga chitoliro chopanda msoko ndi pafupifupi 400,000 t, kuyambira X42 mpaka X70.API mzere zitsulo chitoliro lagawidwa onshore mzere zitsulo chitoliro ndi subsea mzere zitsulo chitoliro.Kupanga mkulu kalasi mzere zitsulo chitoliro panopa kutengera yaying'ono alloying kutentha mankhwala luso.Mtengo wa zitsulo zosapanga dzimbiri zopanda chitoliro ndizokwera kwambiri kuposa chitoliro chowotcherera.Komano, ndi kuwonjezeka kwa kalasi zitsulo, luso ochiritsira wa seamless zitsulo chitoliro n'zovuta kwa sewerolo kukwaniritsa zofunika owerenga.Pakali pano API mzere zitsulo chitoliro kupanga chitoliro akuchita ntchito kafukufuku kuti patsogolo kukana dzimbiri mapaipi ake ndi ntchito khola chilengedwe kutentha otsika kapena mkulu.

API chitoliro chachitsulo chosasunthika

Chitoliro chopanda chitsulo cha API ndi mtundu wa mipiringidzo yayitali popanda seams mozungulira.Chitoliro chamtunduwu chimakhala ndi zigawo zopanda pake.Amagwiritsidwa ntchito kwambiri potengera zinthu zamadzimadzi, monga mafuta, gasi, gasi ndi madzi.Kupanga zigawo za annular ndi API yopanda chitsulo chopanda chitoliro kumatha kupititsa patsogolo kugwiritsidwa ntchito kwa zinthu, kumachepetsa njira yopangira ndikusunga nthawi ya Machining, monga mphete zonyamula, seti za jack etc.Poyerekeza ndi zipangizo zina, kanasonkhezereka seamless zitsulo chitoliro ndi opepuka pamene iwo torsional mphamvu yomweyo.Ndi chuma mtanda gawo zitsulo, choncho chimagwiritsidwa ntchito popanga mbali structural ndi mbali makina, monga kubowola chitoliro, shafts galimoto pagalimoto, mafelemu njinga ndi zomangamanga ntchito scaffolding zitsulo etc.

API welded steel pipe

API molunjika msoko zitsulo chitoliro zikuphatikizapo LSAW zitsulo chitoliro ndi ERW molunjika msoko chitoliro zitsulo.Nthawi zambiri API molunjika msoko zitsulo chitoliro ntchito kufufuza.Kujambula, kugwedeza, kuwonjezera kapu ndi kupukuta ndizofunikira mukamaliza kupanga.API molunjika msoko zitsulo chitoliro amalola kukhalapo zolakwika zazing'ono.Nthawi zambiri, kutalika kwa chitoliro chachitsulo chomwe chimatumizidwa kunja ndi osakwana mita sikisi chifukwa choletsa kukula kwa chidebe.Muyenera kuti mukudziwa mitundu yosiyanasiyana ya API zitsulo chitoliro mutawerenga nkhani pamwamba.Kaya mukugwiritsa ntchito kapena simunagwiritsepo ntchito chitoliro chachitsulo cha API, chidziwitso chotchulidwa pamwambapa ndi choyenera kukumbukira.Ngati simungathe kusunga chidziwitsocho, bwerani ndikujowina okondedwa!
