Carbon Steel Welded Pipe
Chitoliro chopangidwa ndi matako chimapangidwa podyetsa mbale yachitsulo yotentha kudzera muzojambula zomwe zimazigudubuza kukhala zozungulira.Kukanikizira mbali ziwiri za mbale pamodzi kumatulutsa mgwirizano wosakanikirana kapena msoko.Chithunzi 2.2 chikuwonetsa mbale yachitsulo pamene ikuyamba kupanga chitoliro chopangidwa ndi matako
Chodziwika kwambiri mwa njira zitatuzi ndi chitoliro chozungulira.Spiral-welded pipe imapangidwa ndi zitsulo zopindika kukhala zozungulira, zofanana ndi zometa's pole, kenako kuwotcherera komwe m'mphepete mwake amalumikizana kuti apange msoko.Chitoliro chamtunduwu chimangogwiritsidwa ntchito pamapaipi omwe amagwiritsa ntchito zovuta zochepa chifukwa cha makoma ake owonda.Chithunzi 2.3 limasonyeza ozungulira-welded chitoliro monga zikuoneka pamaso kuwotcherera.
Iliyonse mwa njira zitatu zopangira chitoliro ili ndi zabwino ndi zovuta zake.Chitoliro cha matako, mwachitsanzo, chimapangidwa kuchokera ku mbale yopindidwa yomwe imakhala ndi makulidwe a khoma ndipo imatha kuyang'aniridwa ngati ili ndi zolakwika isanapangidwe ndi kuwotcherera.Njira yopangira iyi ndiyothandiza makamaka ngati pakufunika makoma owonda komanso aatali.Chifukwa cha msoko wowotcherera, komabe, nthawi zonse pali kuthekera kwa zolakwika zomwe zimathawa macheke ambiri owongolera omwe amachitidwa panthawi yopanga.
Zotsatira zake, bungwe la American National Standards Institute (ANSI) linapanga malangizo okhwima opangira chitoliro.Pressure Piping Code B31 idalembedwa kuti izilamulira kupanga chitoliro.Makamaka, code B31.1.0 imapereka mphamvu ya 85% ya chitoliro chogubuduza, 60% ya chitoliro chozungulira, ndi 100% yogwira ntchito ya chitoliro chopanda msoko.
Nthawi zambiri, makulidwe a khoma okulirapo amapangidwa ndi njira yopanda msoko.Komabe, pamagwiritsidwe ambiri otsika kwambiri a chitoliro, njira yowotcherera mosalekeza ndiyo yotsika mtengo kwambiri.Chitoliro chopanda msoko chimapangidwa muutali umodzi komanso wawiri wachisawawa.Kutalika kwachisawawa chimodzi kumasiyana ndi 16''-0″ku 20''-0″.Mapaipi 2″ndipo m'munsimu amapezeka muutali wapawiri mwachisawawa kuchokera pa 35''-0″ku 40''-0″.
