Mapaipi esimbi ane dhayamita mahombe anodaidzwawo kuti hombe-diameter galvanized simbi pombi, idzo dzinoreva mapaipi esimbi akasungwa ane kupisa-dip plating kana maelectro-galvanized layers pamusoro pemapaipi makuru-diameter esimbi. Galvanizing inogona kuwedzera corrosion resistance yepombi dzesimbi uye kuwedzera hupenyu hwavo hwebasa. Mapaipi ane galvanized anoshandiswa zvakanyanya. Pamusoro pekushandiswa semapombi epombi ezvinwiwa zvakaderera-zvinodzvinyirira zvakaita semvura, gasi, uye oiri, anoshandiswawo sepombi dzemafuta emugodhi uye pombi dzemafuta muindasitiri yepetroleum, kunyanya minda yemafuta ekumahombekombe, uye semafuta anopisa uye condensation. mumakemikari ekubika midziyo. Mapombi ezvinotonhorera, marasha distillate anowachisa oiri anotsinhanisa, mapaipi emapombi epombi dzetrestle, mafuremu ekutsigira matani emugodhi, nezvimwe.

Yakakura dhayamita yesimbi pombi yekugadzira nzira:

1. Kupisa kusunda dhayamita yekuwedzera nzira

Iyo dhayamita yekuwedzera michina iri nyore, yakaderera-mutengo, iri nyore kuchengetedza, ine hupfumi, uye inogara, uye maratidziro echigadzirwa anogona kuchinjika. Kana iwe uchida kugadzirira hombe-diameter simbi mapaipi uye zvimwe zvigadzirwa zvakafanana, iwe unongoda kuwedzera zvimwe zvishongedzo. Yakakodzera kugadzira mapaipi esimbi epakati uye akatetepa-akakomberedzwa akakura-dhayamita, uye anogonawo kugadzira mapaipi ane madziro akakora asingapfuure kugona kwemidziyo.

2. Kupisa extrusion nzira

Iyo isina chinhu inoda kufanogadziriswa nemachining pamberi pe extrusion. Kana uchiburitsa pombi fittings ine dhayamita isingasviki 100mm, mari yemidziyo idiki, marara emidziyo ishoma, uye tekinoroji yakakura. Zvisinei, kana hupamhi hwepombi huchiwedzera, iyo inopisa extrusion nzira inoda yakakura-tonnage uye yakakwirira-simba midziyo, uye inopindirana yekutonga system inofanirawo kuvandudzwa.

3. Kuboora kunopisa nekukunguruka nzira

Kupisa kuboora kutenderedza kunonyanya kuenderana nelongitudinal rolling yekuwedzera uye kuchinjika-kutenderedza kuwedzera. Longitudinal rolling uye kuwedzera kukunguruka kunosanganisira kuenderera mberi kwechubhu ine mashoma inofamba mandrel, inoenderera chubhu ichitenderedzwa ine limited-stand mandrel, matatu-roll inoenderera chubhu inokunguruka ine mashoma mandrel, uye inoenderera chubhu kukunguruka neinoyangarara mandrel. Idzi nzira dzine hunyanzvi hwekugadzira, kushandiswa kwesimbi kwakaderera, zvigadzirwa zvakanaka, uye masisitimu ekudzora, uye ari kuwedzera kushandiswa zvakanyanya.

Parizvino, maitiro makuru ekugadzirwa kwepombi dzesimbi dzakakura-dhayamita munyika yangu inopisa-yakakungurutswa yakakura-dhayamita yesimbi mapaipi uye kupisa-yakawedzera dhayamita yesimbi pombi. Mamiriro makuru ekupisa-akawedzera seamless simbi mapaipi ari 325 mm-1220 mm uye ukobvu i120mm. Mapaipi esimbi anopisa-akawedzera musono anogona kugadzira hukuru husiri hwenyika. Pombi isina musono ndiyo yatinowanzo kudaidza kuti thermal expansion. Iro pombi yakakasharara yekupedzisa nzira umo mapaipi esimbi ane density yakaderera asi shrinkage yakasimba inowedzerwa nekuchinjika-kukungurusa kana kudhirowa nzira. Kukobvura mapaipi esimbi munguva pfupi inogona kugadzira isiri-yakajairwa uye yakakosha mhando dzemapombi asina musono ane mutengo wakaderera uye yakakwira kugadzirwa. Iyi ndiyo nzira yazvino yekusimudzira mumunda wepombi rolling.

Mapaipi makuru esimbi ane dhayamita anovharwa uye anodziswa asati abuda mufekitari. Iyi mamiriro ekutumira anonzi annealed state. Chinangwa chekugadzirisa ndechekubvisa kukanganisa kwechimiro uye kushushikana kwemukati kwasara kubva pane yakapfuura maitiro uye kugadzirira chimiro uye mashandiro eiyo inotevera maitiro, senge alloy structural simbi, simbi yezvimiro ine yakavimbiswa kuoma, inotonhora musoro simbi, uye kubereka. simbi. Simbi dzakadai sesimbi yekushandisa, steam turbine blade simbi, uye tambo-yemhando yestainless heat-resistant simbi zvinowanzounzwa munzvimbo yakavharwa.

Yakakura dhayamita yesimbi pombi yekugadzirisa nzira:

1. Kukunguruka; nzira yekumanikidza yekumanikidza iyo yakakura-dhayamita simbi pombi simbi blanks inopfuudzwa nepamukaha pakati peya inotenderera inotenderera (yakasiyana maumbirwo). Nekuda kwekudzvanywa kwema rollers, zvinhu zvakayambuka-chikamu zvinoderedzwa uye kureba kunowedzera. Iyi inzira inowanzoshandiswa pakugadzira mapaipi makuru-diameter esimbi. Iyo nzira yekugadzira inonyanya kushandiswa kugadzira yakakura-diameter simbi pombi profiles, mahwendefa, uye pombi. Yakakamurwa kuita inotonhora kukunguruka uye inopisa kukunguruka.

2. Kugadzira; nzira yekumanikidza iyo inoshandisa kudzoreredza kwesando yekuforoma kana kudzvanywa kwemutsindo kuti uchinje chisina chinhu kuita chimiro uye saizi yatinoda. Kazhinji yakakamurwa kuita yemahara forging uye kufa forging, iwo anowanzo shandiswa kugadzira zvinhu zvine mahombe-muchinjiko-zvikamu, hombe-diameter simbi pombi, nezvimwe.

3. Kudhirowa: Inzira yekugadzira iyo inokwevera simbi yakakungurutswa isina chinhu (yakaumbwa, chubhu, chigadzirwa, nezvimwewo) kuburikidza negomba rekufa kupinda muchikamu chakaderedzwa uye kureba kwakawedzera. Mazhinji acho anoshandiswa kutonhora kushanda.

4. Extrusion; inzira yekugadzira iyo mapaipi makuru-diameter esimbi anoisa simbi mune yakavharwa extrusion cylinder uye inoshandisa kumanikidza kune rumwe rutivi kuti ibudise simbi kubva mugomba rakatemerwa kufa kuti uwane zvigadzirwa zvakapedzwa zvechimiro chakafanana uye saizi. Inonyanya kushandiswa mukugadzira. Non-ferrous simbi hombe dhayamita simbi pombi.
