Sarudzo chaiyo yemapombi esimbi isina musono inonyatsoziva!

Ndezvipi zvinodiwa pakusarudza mapaipi esimbi asina musono ekufambisa kwemvura kunowanzo shandiswa muindasitiri yedu yekuita? Tarisa pfupiso yevashandi vedu vepaipi yekumanikidza:

Seamless simbi pombi mapaipi simbi pasina welds kugadzirwa inopisa kurapa nzira dzakadai kuboora uye inopisa kukungurutsa.

Kana zvichidikanwa, pombi yekurapa inopisa inogona kuwedzera kutonhora-inokweverwa kune inodiwa chimiro, saizi uye kuita. Parizvino, mapaipi esimbi asina musono (DN15-600) ndiwo anonyanya kushandiswa mapaipi mumidziyo yekugadzira petrochemical.

Kuongorora: Kazhinji pombi dzesimbi dzekufambisa mvura dzinofanirwa kuongororwa makemikari ekuumbwa, bvunzo dzekusimba, bvunzo dzekubata kumeso uye hydraulic bvunzo. GB5310, GB6479, uye GB9948 yakajairwa simbi mapaipi, kuwedzera kune bvunzo dzinofanirwa kuitwa pamapombi esimbi ekufambisa kwemvura, bvunzo dzemoto uye bvunzo dzemhedzisiro inodiwawo; izvo zvinodiwa zvekuongorora zvekugadzira zvemapaipi matatu esimbi aya zvakaomarara. Iyo GB6479 chiyero inoitawo zvakakosha zvinodiwa kune yakaderera-tembiricha kukanganisa kuoma kwezvinhu. Pamusoro pezvakajairwa bvunzo zvinodiwa zvemapombi esimbi ekufambisa mvura, mapaipi esimbi eiyo GB3087 yakajairwa anodawo bvunzo dzekukotama dzinotonhora. GB/T8163 yakajairika mapaipi esimbi, kuwedzera kune zvakajairwa bvunzo zvinodiwa kune fluid yekufambisa simbi pombi, zvinoenderana nechibvumirano chinoda bvunzo yekuwedzera uye inotonhora yekukotama bvunzo. Zvido zvekugadzira zvemhando mbiri idzi dzemachubhu hazvina kuomarara semhando nhatu dzekutanga.

Kugadzira: GB/T8163 uye GB3087 yakajairwa simbi mapaipi anonyanya kunyungudutswa mumoto wakavhurika kana kushandura, uye kusvibiswa kwavo uye hurema hwemukati hwakakura. GB9948 inonyanya kushandisa kunyungudutsa muchoto chemagetsi. Vazhinji vavo vakabatanidza nzira yekunatsa kunze kwechoto, uye kuumbwa uye kukanganisa kwemukati zvishoma. Iyo GB6479 uye GB5310 miyero pachayo inotaura zvinodikanwa zvekunatsa kunze kwechoto, neine hutsvina hudiki hwekuumbwa uye hurema hwemukati, uye yemhando yepamusoro yezvinhu.

Sarudzo: Kazhinji, GB/T8163 yakajairika pombi yesimbi inokodzera mafuta, mafuta uye gasi uye midhiya yeruzhinji ine tembiricha yekugadzira isingasviki 350 ° C uye kumanikidza kuri pasi pe10.0MPa; yemafuta, mafuta uye gasi midhiya, kana tembiricha yekugadzira inodarika 350 ° C Kana kana kudzvanywa kuri kukuru kupfuura 10.0MPa, GB9948 kana GB6479 yakajairika mapaipi esimbi inofanira kushandiswa; kune mapaipi anoshandiswa muhydrogen, kana mapaipi anoshanda mukushushikana corrosion nharaunda, GB9948 kana GB6479 zviyero zvinofanirawo kushandiswa. Mapaipi ese ecarbon simbi anoshandiswa pakudziya kwakaderera (pasi pe -20 ° C) anofanirwa kutora iyo GB6479 yakajairwa, uye chete inotsanangura zvinodikanwa zvekudzika-tembiricha kukanganisa kuoma kwezvinhu. Iyo GB3087 uye GB5310 zviyero zviyero zvakatemerwa zvakananga kune boiler simbi pombi. Iyo "Boiler Safety Supervision Regulations" inosimbisa kuti mapaipi ese akabatanidzwa kune bhailer ndeaya chiyero chekutarisa, uye kushandiswa kwezvinhu uye zviyero zvinofanirwa kuenderana nezvinodiwa zve "Boiler Safety Supervision Regulations". Naizvozvo, anoshandiswa mumaboilers, zviteshi zvemagetsi, kudziyisa uye petrochemical kugadzira zvivakwa. Mapombi ese eruzhinji (anopihwa nehurongwa) anofanirwa kutora GB3087 kana GB5310 zviyero. Zvakakosha kucherechedza kuti mutengo wemapombi esimbi ane unhu hwakanaka hwesimbi pombi mitemo inenge yakakwirira. Semuenzaniso, mutengo weGB9948 ungangoita 1/5 yakakwirira kupfuura mutengo weGB8163 zvinhu. Naizvozvo, pakusarudza simbi pombi zvinhu zviyero, kutarisisa kwakadzama kunofanirwa kupihwa kune mamiriro ekushandiswa, ayo anofanirwa kuve akavimbika uye Ive ehupfumi. Izvo zvinofanirwa kucherechedzwa kuti mapaipi esimbi zvinoenderana neGB/T20801 uye TSGD0001, GB3087 uye GB8163 zviyero hazvizoshandiswe kune GC1 mapaipi (kunze kwekunge imwe neimwe iri ultrasonic, mhando yacho haina kuderera pane L2.5, uye inogona kuve inoshandiswa GC1 ine dhizaini yekumanikidza isingapfuuri 4.0Mpa pombi).

(二)Low alloy pombi isina musono simbi pombi

Mumidziyo yekugadzira petrochemical, inowanzoshandiswa chromium-molybdenum simbi uye chromium-molybdenum-vanadium simbi isina musono pombi miyero ndeye GB9948 "Seamless simbi pombi yekupwanya peturu" GB6479 "High-kumanikidza musono pombi yesimbi yefetereza michina" GB/T5310 "Seamless simbi pombi ye-high-pressure boiler》GB9948 ine chromium-molybdenum simbi zvinhu mamakisi: 12CrMo, 15CrMo, 1Cr2Mo, 1Cr5Mo, etc. The chromium-molybdenum zvinhu simbi mamakisi akabatanidzwa GB6479: 12CrMo, 15CrMo, 1Cr5Mochmi 3 Mochroum simbi, etc lybdenum vanadium simbi zvinhu mamakisi: 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12Cr1MoVG, etc. Pakati pavo, iyo inonyanya kushandiswa ndeye GB9948, ona pamusoro pekusarudza mamiriro

（三）Seamless Stainless simbi pombi

Inowanzo shandiswa Stainless simbi isina musono pombi miyero ndeiyi:

Pane zviyero zvishanu: GB/T14976, GB13296, GB9948, GB6479, uye GB5310. Pakati pavo, magiredhi maviri chete kana matatu esimbi isina tsvina akanyorwa mumiyero mitatu yekupedzisira, uye haawanzo shandiswa giredhi.

Naizvozvo, kana simbi isina musono pombi mipimo inoshandiswa muinjiniya, GB/T14976 uye GB13296 zviyero zvinonyanya kushandiswa.

GB/T14976 "Simbi isina musono pombi yekufambisa mvura":

Material mamakisi: 304, 304L uye mamwe 19 marudzi akakodzera kune zvakajairika kufambisa mvura.

GB13296 "Simbi isina simbi isina musono machubhu emaboilers uye anotsinhanisa kupisa":

Material mamakisi: 304, 304L uye mamwe makumi maviri neshanu marudzi.

Pakati pavo, Ultra-yakaderera-kabhoni Stainless simbi (304L, 316L) ine yakanakisa corrosion resistance. Pasi pemamwe mamiriro ezvinhu, inogona kutsiva yakagadzikana simbi isina tsvina (321, 347) yekudzivirira ngura kune midhiya; Ultra-yakaderera-kabhoni Stainless simbi ine yakaderera yakakwirira-tembiricha michina zvivakwa, kazhinji Inongoshandiswa patembiricha iri pasi pe525℃; stable austenitic stainless simbi ine zvese zvakanaka corrosion resistance uye tembiricha yekupisa michina, asi Ti iri mu321 iri nyore oxidized uye inorasika panguva yewelding, nekudaro ichideredza kuita kwayo anti-corrosion, mutengo wayo wakakwira, rudzi urwu rwezvinhu runowanzoshandiswa mune zvakawanda. zviitiko zvakakosha, 304, 316 ine general anti-corrosion performance, mutengo wakachipa, saka unoshandiswa zvakanyanya.
