A106gr.B Wopanga Chitoliro Wopanda Msokonezo Wopanga Chitoliro Chachindunji
Chitoliro chopanda chitsulo cha ASTM A106 ndi cha chitoliro chachitsulo chaku America, kuphatikiza a106-a ndi a106-b. Zakale ndi zofanana ndi zapakhomo 10 #, ndipo zomalizirazo ndi zofanana ndi zapakhomo 20 #. Ndi wamba wamba mpweya zitsulo mndandanda ndipo ndi chimodzi mwa zipangizo ambiri ntchito. Chitoliro chopanda chitsulo cha ASTM A106 chimaphatikizapo njira ziwiri: kujambula kozizira ndi kugudubuza kotentha. Kuphatikiza pa njira zosiyanasiyana zopangira, zimasiyana molondola, mawonekedwe apamwamba, kukula kochepa, makina amakina ndi kapangidwe ka bungwe. Amagwiritsidwa ntchito kwambiri mu petroleum, makampani opanga mankhwala, boilers, magetsi, sitima, kupanga makina, magalimoto, ndege, ndege, mphamvu, geology, zomangamanga, mafakitale ankhondo ndi mafakitale ena.
Njira yowerengera ya ASTM A106 yonyamula kukakamiza kwa chitoliro chopanda chitsulo
S = 8; P ndi zosakwana 17.5MPa zitsulo chitoliro chosasunthika, s ndiye chitoliro chachitetezo chosasunthika, ndipo makulidwe a khoma ndi 3mm,
Kuthamanga kovomerezeka kwa chitoliro P = (2)* σ/ S* δ) / D
Kumene: kupanikizika ndi p ndipo makulidwe a khoma ndi δ, Kodi chitoliro chachitsulo chosasunthika ndi chiyani?
Lolani mphamvu yolimba ya zinthuzo ikhale σ, Zhan Rongrong adaphunzira kuti m'mimba mwake mwa chitoliro ndi D;
Kukhuthala kwa khoma δ=( P*D) / (2* σ/ S)
Kumene s ndi chinthu chachitetezo;
Chifukwa P ndi yocheperapo 7MPa, Zhan Jirong adaphunzira kuti s amasankhidwa ngati s = 4;
Timasankha chitetezo monga s = 6; Mphamvu yamakokedwe 20 zitsulo ndi 410mpa, msika zitsulo, ndi awiri akunja chitoliro ndi d.
Chitoliro chachitsulo cha American Standard steel ndi chingwe chachitali chachitsulo chokhala ndi dzenje ndipo palibe mfundo zozungulira. Chitoliro chachitsulo chili ndi gawo lobowo ndipo chimagwiritsidwa ntchito kwambiri ngati mapaipi otumizira madzimadzi. Chitoliro chachitsulo chosasunthika chaku America, monga mapaipi otumizira mafuta, gasi, gasi, madzi ndi zida zina zolimba. Poyerekeza ndi zitsulo zolimba monga zitsulo zozungulira, chitoliro chachitsulo chimakhala ndi kupindika komweko ndi mphamvu yozungulira komanso kulemera kwake. Ndi chuma gawo zitsulo. Amagwiritsidwa ntchito kwambiri popanga zida zamakina ndi zida zamakina, monga chitoliro chobowola mafuta, shaft yotumizira magalimoto, chimango cha njinga ndi scaffold yachitsulo yomwe imagwiritsidwa ntchito pomanga. Kupanga mphete zokhala ndi mapaipi achitsulo kumatha kupititsa patsogolo kugwiritsiridwa ntchito kwa zinthu, kufewetsa njira zopangira, ndikusunga zida ndi maola okonza, monga mphete zokhala ndi mphete, ma Jack manja, etc. mapaipi achitsulo akhala akugwiritsidwa ntchito kwambiri popanga. Chitoliro chachitsulo ndi chinthu chofunikira kwambiri pamitundu yonse ya zida wamba. Mfuti ndi mbiya ziyenera kupangidwa ndi chitoliro chachitsulo. Chitoliro chachitsulo chikhoza kugawidwa mu chitoliro chozungulira ndi chitoliro chapadera chofanana ndi malo osiyanasiyana ozungulira ndi mawonekedwe. Chifukwa dera lozungulira ndilo lalikulu kwambiri pansi pa chikhalidwe chofanana, madzi ambiri amatha kunyamulidwa ndi chitoliro chozungulira. Kuonjezera apo, pamene gawo la mphete likukhudzidwa ndi kupanikizika kwa ma radial mkati kapena kunja, mphamvuyo imakhala yofanana. Choncho, mapaipi ambiri achitsulo amakhala ozungulira.
Pakati pa mipope yachitsulo yaku America, ASTM A53 gr. B chitoliro chachitsulo chosasunthika pazolinga zonse, ASTM A106 / A53 gr. B chamfered ndi chamfered zitsulo chitoliro, bs1387-1985 British muyezo ERW mkulu pafupipafupi welded chitoliro ndi kanasonkhezereka chitoliro, ASTM A333 - 40 ℃ - 101 ℃ otsika kutentha osasokonekera zitsulo chitoliro, ASTM A179 msoko chitoliro chitsulo exchanger kutentha ndi condenser. Kutalika kwa chitoliro chachitsulo: 5.8m, 6m mpaka 12m, Ikhozanso kusinthidwa malinga ndi zosowa za wosuta.
Kuzungulira kwakunja kwa chinthucho ndi 1/2 "- 28", 21.3-711.2mm, ndipo makulidwe a khoma ndi sch30, sch40, STD, XS, sch80, sch160, XXS, ndi zina zotere. - Chithandizo cha dzimbiri ngati chikufunikira, ndi zipewa za pulasitiki za chitoliro pa malekezero onse awiri, chamfering ngati pakufunika, ndi kuyendera katundu.
