Kana uchangobva kuita mapurojekiti makuru emapaipi emupombi, kungave kwesimba remhepo, madoko kana mabhiriji, pakusarudza zvinhu zvepombi nenzira yekuvaka, musanganiswa mumwe chete haudzivisiki: pombi yesimbi yekabhoni ine FBE + welding yearc inonyungudutswa kaviri.
Usamhanye kutarisa mashoko aripo parizvino. Ngatitangei takurukura dambudziko rinoshanda rinosangana naro panzvimbo yekuvaka - nharaunda yepasi pevhu "inonetsa" zvikuru. Yakanyorova, inokurumidza kuita ngura, uye mutoro unochinja-chinja kakawanda. Mapaipi akajairwa anowanzo shanda zvisina kunaka mushure memakore mashoma ekushandiswa. Ndosaka makambani akawanda einjiniya ari kutendeukira kuASTM A252 yakawandavanotumira kunze kwenyika kuti vawane huwandu hwakawanda hwemapaipi emurwi akakura.
Munguva pfupi yapfuura, takaita hurukuro nefekitori yakambovambwa muCangzhou nezveboka rezvinhu. Maitiro avo akakodzera kugoverwa.
Haasi ese mapombi eFBE inner liner akafanana.
Ngatitaurei nezve FBE. Vanhu vazhinji vanoziva nezvayo sehupfu hwe epoxy hwakasungirirwa. Zvisinei,Pombi yesimbi yekabhoni yakagadzirwa neFBE Zvinoshandiswa mumapombi emurwi zvine zvinodiwa zvakasimba maererano nekunamatira, ukobvu, uye tembiricha yekupisa.
Chigadzirwa chatiri kutaura nezvacho panguva ino chinobva kuCangzhou Spiral Steel Pipes Group Co., Ltd. Fekitori iyi yakavambwa muna 1993 muCangzhou, Hebei Province. Inofukidza nzvimbo inosvika 350,000 square metres uye ine pfuma inosvika mamiriyoni 680 yuan. Ine vashandi 680. Vanogadzira matani 400,000 emapaipi esimbi anotenderera gore rega rega, ane mutengo we1.8 bhiriyoni yuan. Ndivo vari pakati pevanotungamira mumunda wemapaipi esimbi anotenderera uye zvigadzirwa zvakaputirwa.
Mapaipi esimbi yekabhoni akagadzirwa neFBE haana kungo "shandisa hupfu" chete. Asi, anodzora zvakanyanya kumhanya kwetambo yekuputira uye tembiricha munzvimbo yekupisa, zvichibvumira FBE kupinda nepamusoro pepombi yesimbi, ichigadzira jira rekudzivirira rakakora, rinoramba richienderera mberi uye rinodzivirira cathode.
Sei zvichikosha kutarisisa maitiro ekunamira mapaipi emurwi?
Mamiriro ekumanikidzwa kwemapombi emurwi akasiyana zvachose neemapaipi emvura akajairwa. Simba rekurovera panguva yekufambisa murwi, simba reaxial pasi pemutoro wenguva refu, uye kusagadzikana kwepasi pevhu zvese zvinoda kuti welds dzive dzakavimbika zvakakwana.
Fekitori iyi iri muCangzhou inoshandisa welding ye arc ine arc mbiri. Avo vanoziva welding vanoziva kuti mukana mukuru wekuita izvi ndewekuti weld seam yakagadzirwa zvakanaka, kudzika kwayo kwakanyungudutswa kwakakwana, uye mwero wekukuvara kwemukati wakaderera. Uyezve, welding yemativi maviri yakafanana nekuisa "inshuwarisi mbiri" pamusero we weld, sezvo ichivimbisa kupinda kwakazara mukati nekunze.
Zvichienzaniswa nekukwevera mativi ese kana kukwevera kwakajairika kwespiral, mapaipi emurwi ane dhayamita hombe anogadzirwa newelding ye arc ine arc mbiri pasi pemvurainoratidza kugadzikana kuri nani zvikuru kana iine zvinhu zvinorema uye zvinokotama. Izvi zvinodiwa kuti mapaipi emurwi ashande zvakanaka.
Mapombi makuru ane dhayamita - sei vanhu vakawanda vava kusarudza kutenga zvinhu zvakawanda?
Zvino tasvika panyaya yataurwa mumusoro wedu: Sei tichitengesa mapaipi eASTM A252 FBE ane DSAW akagadzirwa nemafuta akawanda?
Mhinduro yacho iri nyore - kugadzikana + mari inodzoreka.
ASTM A252 imhando chaiyo yemapombi esimbi anoshandiswa pamapombi, ane zvinodiwa zvakajeka kuti agone kusimba, kusimba kwekudhonza, uye kureba. Fekitori iyi iri muCangzhou inogadzira zvakananga mapaipi emapombi ane dhayamita hombe zvichienderana nemutemo uyu, uye ivo zvakare vatengesi veASTM A252, zvichibvisa kudiwa kwevanopindirana.
Kumakambani einjiniya, kutenga mapaipi makuru emapaipi akawanda kubva kuvagadziri vakadaro kamwe chete kwakanakira nekuda kwezvikonzero zvakasiyana-siyana. Chekutanga, zvinodiwa zvakafanana uye mhando yacho inoteverwa. Chechipiri, mutengo wacho unokwikwidzana zvechokwadi. Chechitatu, kutenderera kwekugovera zvinhu kunogona kudzorwa - fekitori ine kugona kwekugadzira kwematani 400,000 pagore haina hurongwa hwekugadzira uye kugona kwekuunganidza zvinhu zvisina kugadzirwa sezvinogona kuenzaniswa nemaworkshop madiki.
Muchirongwa chaicho, mapaipi aya anoshandiswa kupi?
Heano mamwe mamiriro chaiwo:
Chiteshi chengarava nechiteshi chengarava: Mapombi anofanira kuramba ngura mumvura yegungwa. Kushanda zvakanaka kwepombi dzesimbi dzekabhoni dzakagadzirwa neFBE kwakanakira zvikuru kupfuura kwepombi dzisina chinhu.
Hwaro hwebhiriji: Zvinodiwa zvakanyanya zvinoiswa pamisungo yeweld. Maitiro ekuwelda arc akadzika kaviri anogona kuve nechokwadi chekuti chubhu yega yega yemurwi inofanana.
Nheyo yeshongwe yeturbine yemhepo: Dhayamita yakakura, kuviga kwakadzika, inotakura mutoro kwenguva refu. Mapaipi ekuisa dhayamita hombe, zvichienderana neASTM A252 standard, isarudzo yakajairika muindasitiri.
Zvigadzirwa zvefekitori iyi muCangzhou zvinonyanya kugoverwa munzvimbo idzi. Uyezve, mukana wazvo uri pakuti hazvingogadziri mapombi akasungirirwa nesimbi chete asiwo zvinoitisa maitiro ekumonera. Maitiro ekugadzira akabatana zvakanyanya, uye anogonawo kudzora mhando kusvika pakupera.
Muchidimbu, hapana kurova musango.
Kana uchitsvaga mapaipi esimbi yekabhoni akafukidzwa neFBE, ane zvinodiwa zvakasimba zvemaseam eweld (anofanira kunge akasungirirwa kaviri pasi pearc), uye kana purojekiti yako ichida mapaipi emurwi ane dhayamita hombe, uye uri kutsvaga mutengesi weASTM A252 akavimbika - Cangzhou Spiral Steel Pipe Group isarudzo yakakodzera kufungwa nezvayo.
Hazvirevi kuti dzakachipa zvisingaite; asi, ndezvekuti muchikamu ichi, hapana vagadziri vakawanda vemuno vanogona kubatanidza kugona kwekugadzira, hunyanzvi, maitiro, uye kuputira zvese panguva imwe chete.
Saka, sei uchifanira kusarudza mapaipi eASTM A252 FBE ane DSAW akaputirwa nemutengo wakaderera kuti aunganidzwe?
Mhinduro iri nyore ndeyekuti: iri nyore kushandisa, yakasimba zvikuru, uye inogona kutsungirira miedzo iri muvhu.
