High pressuremavharuvhu imhando yemavharuvhu iyo inogona kumira kumanikidzwa uye inoshandiswa kutakura zvinwiwa.Kune marudzi akawanda emavharuvhu, kusanganisira simbimavharuvhu, mhanguramavharuvhu, simbi isina nguramavharuvhu, nevamwe.
High pressure steelmavharuvhu vari inonyanya kushandiswa kugadzira yakakwirira-mhando kabhoni structural simbi, alloy structural simbi, uye simbi isina kupisa isingadziviriri seamless simbi.mavharuvhu for steam boiler mapaipi pasi pekumanikidzwa kwakanyanya uye pamusoro.Boiler izvimavharuvhu inogona zvakare kupinda oxidation uye corrosion kana uchishanda pakupisa kwakanyanya uye kudzvanywa kwakanyanya, uye pasi pechiito chepamusoro-tembiricha flue gasi uye mhute yemvura.Naizvozvo, simbimavharuvhu vanodiwa kuti vave nesimba rekushingirira rakakwirira, kukwirira kweoxidation kuramba, uye kugadzikana kwakanaka kwesangano. Magiredhi esimbi anoshandiswa anosanganisira: emhando yepamusoro kabhoni yekugadzira simbi mamakisi anosanganisira 20G, 20MnG, uye 25MnG.. Alloy zvimiro zvesimbi mamakisi 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB, nezvimwe.. Simbi ine ngura uye inodzivirira kupisa 1Cr18Ni9 uye 1Cr18Ni11Nb yakakwirira-kudzvanywamavharuvhu anowanzoshandiswa.
Pamusoro pekuve nechokwadi chekuumbwa kwemakemikari uye zvivakwa zvemuchina, pombi yega yega inofanirwa kuongororwa kudzvanywa kwemvura, kusanganisira yekuwedzera uye kudzikamisa bvunzo.Simbimavharuvhu dzinounzwa mumamiriro ekupisa.Pamusoro pezvo, pane zvimwe zvinodikanwa zveiyo microstructure, saizi yezviyo, uye decarburization layer yesimbi yakaperamavharuvhu.Simbi isina musonomavharuvhu yekuchera geological uye petroleum drilling control. Kuongorora chimiro chematombo epasi pevhu, mvura yepasi, oiri, gasi rechisikigo, uye zvicherwa zviwanikwa, chidhinha chinoshandiswa kuchera matsime.Kubviswa kwemafuta uye gasi rechisikigo hakugoni kuparadzaniswa kubva kumatsime ekuchera.Simbi isina musonomavharuvhu inoshandiswa pakuchera geological uye kutonga ndiyo huru yemidziyo yekuchera, kunyanya kusanganisira yekunze coremavharuvhu, mukati mukatimavharuvhu, makaseti, chibooresomavharuvhu, etc. Pamusana pemamiriro ekushanda akaoma zvikuru ekucheramavharuvhu izvo zvinoda kupinda mukati mezviuru zvemamita ehupamhi hwe geological, iyo drillmavharuvhu vanoiswa pasi pekunetsekana senge tension, compression, kukotama, torsion, uye kusaenzana kukonzeresa mitoro, pamwe nekuiswa mumadhaka nematombo.Naizvozvo, zvinodikanwa kutimavharuvhu inofanira kuva nesimba rakakwana, kuoma, kupfeka kuramba, uye kuoma kwesimba.
Simbimavharuvhu inomiririrwa ne "DZ" (iyo Chinese phonetic prefix ye geology) uye nhamba yekutanga kumiririra goho resimbi, Inowanzo shandiswa simbi mamakisi anosanganisira 45MnB uye 50Mn yeDZ45.. 40Mn2 uye 40Mn2Si yeDZ50. 40Mn2Mo uye 40MnVB yeDZ55. 40MnMoB yeDZ60 uye 27MnMoVB yeDZ65.Simbimavharuvhu dzinounzwa mumamiriro ekupisa.Petroleum cracking pombi: Pombi isina musono inoshandiswa muchotomavharuvhu, kupisa kupisamavharuvhu, uye mapaipi ari munzvimbo dzinocheneswa petroleum.Inowanzoshandiswa pakugadzira yepamusoro-soro kabhoni simbi (10, 20), alloy simbi (12CrMo, 15CrMo), kupisa-resistant simbi (12Cr2Mo, 15Cr5Mo), uye Stainless simbi (1Cr18Ni9, 1Cr18Ni9Ti).Pamusoro pekuwana certification yemakemikari ekuumbwa uye akasiyana ma mechanical properties, simbimavharuvhu zvakare inofanirwa kuongororwa senge kudzvinyirirwa kwemvura, kubata kumeso, uye kupisa, pamwe nehupamhi hwepamusoro uye kuyedza kusaparadza.
Simbimavharuvhu dzinounzwa mumamiriro ekupisa.Simbi isina nguramavharuvhu: Simbi isina nguramavharuvhu ayo anopisa-akakungurutswa kana kutonhora-akakungurutswa nemhando dzakasiyana-siyana dzesimbi isina tsvina anoshandiswa zvakanyanya mupetroleum nemakemikari emidziyo mapaipi, pamwe chete nesimbi isina simbi yezvimiro zvezvinangwa zvakasiyana.Pamusoro pekuvimbisa kuumbwa kwemakemikari uye michina zvivakwa, ese simbimavharuvhu inoshandiswa kumirisana nekumanikidzwa kwemvura inofanirwa kuve nechokwadi chekuti vapasa iyo hydraulic test.Various specialized steelmavharuvhu inofanira kuvimbiswa maererano nemamiriro akataurwa.
