Seamless square steel tubing, Ke motsoako o thata oa tšepe oa martensitic.E fapane le sehlopha sa austenite
E ka phekoloa mocheso (" quenched and tempered ") ho hlahisa matla a phahameng le ductility e ntle.Ha ho hlokahala matla, ho thatafala le ho apara ho hanyetsa 'me o na le khanyetso e itseng ea kutu
Ka lebaka la bokhoni bo thata ba tšepe ena, lisebelisoa tse ling tsa thepa ena le thepa e hlahisoang li tla ameha ka tekanyo e itseng.Alloy e ka sebelisoa ka mokhoa o atlehileng feela libakeng tse senyang hanyenyane.Mocheso o sebetsang o lekanyelitsoe a) Ho futhumala ho feteletseng ha mocheso o phahameng ho fella ka ho lahleheloa ke matla le b) tahlehelo ea ductility mochesong o ka tlaase ho zero.
Seamless square steel tubing, tšepe ena e loketse bakeng sa ho etsa likarolo tse phahameng tsa khatello ea maikutlo liindastering tse fapaneng, ho kenyeletsoa lik'hemik'hale tsa petrole, tsa likoloi le tsa motlakase.
Seamless Square Steel Tubing, The Main Performance
1. Polasetiki
Plasticity e bolela bokhoni ba lisebelisoa tsa tšepe ho hlahisa deformation ea polasetiki (deformation e sa feleng) ntle le tšenyo tlas'a mojaro.
2. Ho thatafala
Ho thatafala ho lekanya hore na tšepe e thata kapa e bonolo hakae.Bophelong bona tlhahiso ea mokhoa oa ho lekanya boima ke mokhoa o sebelisoang ka ho fetisisa ka mokhoa oa ho thatafala ha indenter, ke ho sebelisa sebopeho se itseng sa geometri sa hlooho ea indenter tlas'a mojaro o itseng ka holim'a thepa ea tšepe e lokelang ho lekoa, ho latela tekanyo ya lenaka ho fumana boleng ba boima.
Mekhoa e sebelisoang hangata ke Brinell hardness (HB), Rockwell hardness (HRA, HRB, HRC) le Vickers hardness (HV) le mekhoa e meng.
3. Mokhathala
Matla, polasetiki le ho thatafala ke matšoao a thepa ea mechine ea tšepe tlas'a mojaro o tsitsitseng.Ha e le hantle, likarolo tse ngata tsa mochine li sebetsa tlas'a meroalo ea cyclic, 'me mokhathala o ka hlaha tlas'a maemo ana.Tsela e boetse e hloka ho ba le sebopeho se seng sa karolo ea phala ea tšepe e nang le sebōpeho se khethehileng.
Phaephe ea tšepe e nang le khatello e tlase (GB/T3092-1993) e boetse e tsejoa e le phala e akaretsang, e tsejoang ka hore ke phala e ntšo.Ke phala ea tšepe e cheselitsoeng e sebelisetsoang ho tsamaisa metsi, khase, moea, oli, mouoane o futhumatsang le maro a mang a akaretsang a tlase a khatello le merero e meng.Botenya ba lerako la phala ea tšepe bo arotsoe ka phala e tloaelehileng ea tšepe le phala e teteaneng ea tšepe.Foromo ea ho qetela ea liphaephe e arotsoe ka li-non-rebar steel tube (light tube) le e nang le tube ea tšepe ea rebar.Litlhaloso tsa li-tube tsa tšepe li bontšoa ka bophara ba lebitso (mm), e leng tekanyo ea bophara ba ka hare.Ho tloaelehile ho sebelisa lisenthimithara tse kang 11/2.Peipi ea tšepe e cheselitsoeng e sebelisoang bakeng sa lipalangoang tsa mokelikeli o tlaase o sebelisoa haholo-holo e le phala ea pele ea phala ea tšepe e entsoeng ka masenke e sebelisetsoang ho tsamaisa mokelikeli o tlaase.
Peipi ea tšepe e entsoeng ka galvanized bakeng sa lipalangoang tsa mokelikeli o tlase (GB/T3091-1993) e boetse e tsejoa e le phala ea tšepe e entsoeng ka masenke, e tsejoang ka hore ke phala e tšoeu.Ke peipi ea tšepe e chesang e kolobisitsoeng (chesello ea sebōpi kapa ea motlakase) e sebelisetsoang ho tsamaisa metsi, khase, oli ea moea, mouoane o futhumatsang, metsi a futhumetseng le maro a mang a tloaelehileng a tlaase kapa merero e meng.Botenya ba lebota ba phala ea tšepe bo arotsoe ka phala e tloaelehileng ea galvanized tšepe le phala e teteaneng ea tšepe.Qetello ea phala e arotsoe ka phala ea galvanized tšepe ntle le khoele le phala ea tšepe e nang le khoele.
Common carbon steel wire bushing (GB3640-88) e sebelisetsoa ho sireletsa terata mehahong ea indasteri le ea sechaba, mechine ea ho kenya le lisebelisoa le merero e meng ea ho kenya motlakase.
Seam seam electric welded steel pipe (YB242-63) ke phala ea tšepe e nang le li-welds tsa longitudinally parallel.Hangata e arotsoe ka metric welded tšepe phala, welded tšesaane-lebota phala, transformer cooling tubing joalo-joalo.
Spiral seam submerged arc welded steel pipe (SY5036-83) bakeng sa sepalangoang sa mokelikeli oa khatello ke phala ea tšepe ea spiral seam, e entsoeng ka tšepe e chesang e kolobisitsoeng e le tube e se nang letho, e atisang ho thehoa mocheso o futhumetseng 'me e chesetsoa ka mokhoa oa ho tjheseletsa ka mahlakoreng a mabeli. .Pipe ea tšepe e na le matla a ho jara le ts'ebetso e ntle ea welding.E bolokehile ebile e ka tšeptjoa ho sebelisoa ka mor'a mefuta eohle ea tlhahlobo le tlhahlobo e tiileng ea mahlale.Pipe e kholo ea tšepe e nang le bophara bo boholo, ts'ebetso e phahameng ea phetisetso, 'me e ka boloka matsete a ho beha liphaephe.E sebelisoa haholo ho tsamaisa lipeipi tsa oli le khase ea tlhaho.
