Pipe umboko wegesi

Namhlanje kunzima ukucinga ihlabathi kunye nobomi babo ngaphandle impumelelo inzululwazi neteknoloji. Abantu abaninzi bakholelwa ukuba impumelelo engundoqo kuphuhliso lolwazi. Kodwa nje ubomi bakho ngaphandle izibonelelo industrial! Kubomi bemihla ngemihla, bonke kunandipha iingenelo impucuko: amanzi, umbane, irhasi, ubushushu - kwaye ukucinga ubomi obutofotofo ngaphandle kwazo. Ukuze ukuhambisa amanzi kunye negesi, namanzi negesi imibhobho nakhelwe ukuba abe kwisithuthi.

Xa obandayo abakhi esetyenziselwa kwimibhobho emikhulu igesi. Kubalulekile ukuqaphela ukuba yinxalenye yobomi bethu bemihla ngemihla ukulidla anendima njengesixhobo eliphantsi iindleko lokuhanjiswa ulwelo kunye negesi.

Yintoni umbhobho?

Okwangoku, akukho impendulo eyodwa lo mbuzo. Ngokubanzi sinokuthi ukuba umbhobho - yinto inqaku wokwenziwa yabucala basemgongxweni, esetyenziswa ukuthuthwa igesi, neoli, ulwelo ezahlukeneyo, nobushushu, unyanzeliso.

ngezigaba imibhobho

imibhobho eriyeli ukuba liqengqiwe (ehlelayo ashushu nabandayo), icinezelwe (ubukhulu 820 mm), waphosa (intsimbi kunye intsimbi, ububanzi 900 mm).

Kwi kwicandelo iprofayile ukwahlula iimilo, ngeenxa zonke;

• Square.

• okoxande.

• Khan.

• Ingxenye.

• exabe.

• teardrop-ezimile.

• ezineminyaka, emithathu yaye libe.

yohlulwe icandelo longitudinal:

• Tapered.

• wawanqanda kunye eziphelweni kwamcaphukisa.

Lo asinguye uluhlu lonke ngemibhobho eyahlukileyo kwi-moya longitudinal. Xa iqela eyahlukileyo ezi bimetallic, trimetallic, eliquka lamanqanaba eziliqela isinyithi, abaqhagamshelwe kunye yi welding, Bhubane okanye lokutyala.

Ukusetyenziswa kwemibhobho eriyeli

Ngenxa kwengqesho ziyafumaneka:

• ushishino oyile negesi;

• Ukwakhiwa;

• babetha;

• Mechanical Engineering;

• iimpahla kunye namatanki.

Imibhobho kwishishini oyile negesi eyenziwe carbon kunye ingxubevange yodidi. umbhobho drill isetyenziselwa ukubhola kunye nobukrelekrele yokusebenza. Casings asetyenziswa ukukhusela iindonga igesi, neoli kakuhle umhlwa ukungena yokuzahlula fluid enye kwenye kunye negesi okugcina amanzi. Imibhobho for lwemibhobho ezisetyenziselwa ukunikezelwa igesi, neoli, ipetroli, amanzi, asidi. Zokutyubhisha ezisetyenziswa amaqula yokomba operation xa imveliso oyile kwenzeka, yaye ukuba azinamsonto unxulumano. ngemibhobho Boiler ezisetyenziswa boilers eziintlobo ezahlukeneyo. umbhobho ephambili yenziwa ngokuhambelana GOST 3262-75 kwaye welding. ukwakhiwa Pipe ngokutsho GOST 800-78, 8642-68 isetyenziswa ekwenziweni izahlulo umatshini ezahlukeneyo kubunjineli moya, ye tektala. Imibhobho ngokuhlaziya, ngokungqinelana GOST 550-75, ezenziwe ngentsimbi 10, 20, K5M, K5 12MH kunye nabanye kwaye kusetyenziswa sokumpompa ioli koxinzelelo oluphezulu.

pipe ngumboko

Eyona iphambili umbhobho gauge ubukhulu mkhulu, kuba asetyenziswa for obandayo izakhiwo ezahlukeneyo ekwakheni, zokuthuthwa ioli, ipetroli, umphunga, oyile, irhasi kunye namanzi.

pipe steel komboko ezijikeleze-welding eyenziweyo, ububanzi 529-2560 mm kunye Ebubanzini bodonga 8-25 mm. Imibhobho for mbane irhasi enziwayo ukuze basebenze kwiindawo bako, ngamandla eziphezulu kunye neemeko zemozulu ezinzima. Ngenxa yoko, indawo le kwiindawo eziphambili oyile negesi e North eRashiya kubeyimfuneko ukwakhiwa kwemibhobho buti enamandla akhiwe komhlaba.

iimeko zemozulu ezinzima zibagcine phezulu kakhulu kumgangatho kwemibhobho kunye neempawu zakusebenza - amandla kunye plasticity neempawu. Ngamanye amaxesha pipe igesi Umboko yayisoma okhethekileyo: zizonke, zinc, bituminous.

National Association of nokumelana Engineers (NACE) kuye kwenziwa umlinganiselo elawula uvavanyo kunye neengcebiso ngezixhobo abanganyangekiyo wazifefa iindawo emanzini. Iikhrayitheriya nokuhlola ukufaneleka umbandela: ixesha lokuba ukungaphumeleli kunye ombane zisembundwini wawo.

Ngokuba izinto tube, asetyenziswa kwiimeko ezinzima zemozulu, oko ukuncipha obalulekileyo lobushushu apho brittleness ye intsimbi kwenzeka, ukuphucula iimpawu zayo viscous, ekuye kwagqitywa malunga nemiboniso kunye liqatywe setyhula lobushushu ubuncinane -60 ° C kwaye iisampulu iphantsi ukwenzeka inotshi ezibukhali lobushushu yokusebenza 20 ° C. Kungenxa yoko le nto kubaluleke kangaka ukuyisebenzisa imibhobho eziphambili ezenziwe GOST okanye DB.

Lomqolo tube: Standard kunye neNgcaciso

Ukwahlula umbhobho osemqoka:

1. Indlela iwelding:

• Resistance welding.

• Arc welding.

2. Uhlobo weld:

• Spiral.

• welding longitudinally.

3. Injongo:

• Imibhobho for lwemibhobho eziphambili.

• Imibhobho for mbane igesi.

• Imibhobho for lwemibhobho isiqu kunye namanye amajelo eendaba.

4. Ububanzi:

• Imibhobho of ubudeki enkulu.

• Imibhobho of omncinci.

Kubalulekile ukukhumbula ukuba arc welding - indlela jikelele, kunye nomfowunelwa nohlobo iwelding isetyenziswa kuphela umbhobho ephambili kunye omncinci. Iinkqubo Pipe Mcetywa zerhasi enobubanzi enkulu na tortsovannoy, kunye Isipha ziyasuswa. Ukuba pipe ayikho tortsovannaya, Isipha na kususwa kwi mveliso.

GOST 20295-85 - yeyona regulatory uxwebhu oluphambili kwi kwimibhobho eziphambili.

Umbhobho umboko: Gauge

Njengoko okusilelayo ukuze imveliso lombhobho sentsimbi lomqolo strip sobhedu isetyenziswa, izinto ngawo ezivelileyo carbon exutyiweyo kakhulu (cwaka, semi-wabulala) zentsimbi kunye ephantsi ingxubevange steel ehlelayo eshushu.

Yodidi ezisetyenziselwa ukuvelisa yombhobho engundoqo:

• 10;
• 20;
• 09GSF;
• 10G2FBYU.

Pipe backbone zombane GOST 20295-85, TU 14-3-1573-96:

Njengoko kubonakala, umbhobho lusetyenziswayo kwiimeko entsonkothileyo zejoloji kunye zemozulu, bume bako kwaye yenziwa ngokwe GOST kunye TU, a asolwa enkulu bayiqinisa indawo phakathi kwezinye engundoqo onenombolo kumbhobho metal.
