Alloy seamless simbi pombi imhando yesimbi isina musono pombi, uye kuita kwayo kwakakwira zvakanyanya kupfuura iyo yakajairwa seamless simbi pombi, nekuti iyi pombi yesimbi ine yakawanda Cr, uye yakanyanya tembiricha kuramba, kushoma tembiricha kuramba uye corrosion kuramba kuita zviri nani pane. dzimwe pombi dzesimbi dzisina musono. Isingaenzaniswi, saka alloy machubhu anoshandiswa zvakanyanya mu petroleum, makemikari, magetsi emagetsi, boiler uye mamwe maindasitiri. Alloy seamless simbi chubhu (Seamless Steel Tube) ine mhango chikamu, refu simbi tambo isina majoini akaitenderedza. Iyo pombi yesimbi ine mhango chikamu uye inoshandiswa zvakanyanya sepombi yekutakura zvinwiwa, semapaipi ekutakura oiri, gasi rechisikigo, gasi, mvura uye zvimwe zvinhu zvakasimba. Kuenzaniswa nesimbi yakasimba senge simbi yakatenderera, alloy seamless simbi pombi ine yakafanana flexural uye torsional simba uye kureruka uremu. Icho chikamu chehupfumi chikamu chesimbi uye chinoshandiswa zvakanyanya mukugadzirwa kwezvikamu zvekugadzirisa uye zvikamu zvemagetsi, zvakadai sekutakura mafuta. Kugadzira zvikamu zvemhete nealloy seamless simbi pombi kunogona kuvandudza mwero wekushandiswa kwezvinhu, kurerutsa maitiro ekugadzira, kuchengetedza zvinhu uye nguva yekugadzira, senge rolling bearing rings, jack sets, nezvimwewo, izvo zvakashandiswa zvakanyanya mukugadzira pombi yesimbi. Alloy seamless simbi pombi zvakare chinhu chakakosha kune akasiyana akajairika zvombo, uye dhiramu, dhiramu, nezvimwe zvinofanirwa kugadzirwa nesimbi pombi. Mukuwedzera, apo chikamu chemhete chinoiswa pasi pemukati kana kunze kwemhepo, simba racho rinenge rakafanana. Naizvozvo, mazhinji alloy seamless simbi mapaipi mapaipi akatenderera.
Classification:
Structural seamless simbi pombi: inonyanya kushandiswa kune yakajairwa chimiro uye mechanical chimiro. Mumiririri wayo zvinhu (brand): carbon simbi 20, 45 simbi; alloy simbi Q345, 20Cr, 40Cr, 20CrMo, 30-35CrMo, 42CrMo, nezvimwewo.
Mapaipi esimbi asina musono ekufambisa mvura: inonyanya kushandiswa kufambisa mapaipi emvura muinjiniya nemidziyo mikuru. Iyo inomiririra zvinhu (giredhi) ndeye 20, Q345, nezvimwe.
Seamless simbi mapaipi epasi uye epakati pressure boilers: inonyanyo shandiswa mapaipi ekufambisa yakaderera uye yepakati kudzvanywa zvinwiwa mumaindasitiri boilers uye epamba boilers. Iyo inomiririra zvinhu ndeye 10, 20 simbi.
Seamless simbi mapaipi kune yakakwira pressure boilers: inonyanya kushandiswa kwekushisa kwakanyanya uye kudzvinyirira kwakanyanya kutakura misoro yemvura uye pombi pamaboilers mumagetsi emagetsi uye zvidyarwa zvemagetsi enyukireya. Zvishandiso zvinomiririra ndezve 20G, 12Cr1MoVG, 15CrMoG, nezvimwe.
Mapaipi esimbi asina musono emhando yepamusoro fetireza midziyo: inonyanya kushandiswa kwepamusoro-tembiricha uye yakakwirira-kudzvanywa kwemvura mapaipi pamidziyo yefetereza. Zvishandiso zvinomiririra 20, 16Mn, 12CrMo, 12Cr2Mo, nezvimwe.
Mapaipi esimbi asina musono ekutsemuka oiri: inonyanya kushandiswa mumaboilers, zvinopisa zvinopisa uye mapaipi ekufambisa kwemvura mumafuta anonyungudutsa. Zvishandiso zvaro zvinomiririra 20, 12CrMo, 1Cr5Mo, 1Cr19Ni11Nb, nezvimwe.
Mapaipi esimbi asina musono emasilinda egasi: anonyanya kushandiswa kugadzira akasiyana gasi uye hydraulic silinda. Zvinhu zvaro zvinomiririra 37Mn, 34Mn2V, 35CrMo uye zvichingodaro.
Mapaipi anopisa-akatenderedzwa asina musono e hydraulic props: anonyanya kushandiswa kugadzira hydraulic tsigiro, masilinda uye makoramu mumigodhi yemarasha, pamwe nemamwe ma hydraulic silinda nemakoramu. Zvishandiso zvaro zvinomiririra 20, 45, 27SiMn, nezvimwe.
Inotonhora-inodhonzwa kana kutonhora-yakakungurutswa precision isina musono simbi pombi: inonyanya kushandiswa kwemakanika chimiro, kabhoni yekutsikirira michina, inoda yakakwirira dimensional kurongeka uye yakanaka kupera kwepamusoro. Iyo inomiririra zvinhu ndeye 20, 45 simbi, nezvimwe.
