Pipe hunde gasi Mapaipi

Nhasi zvakaoma kufungidzira nyika uye hwavo pasina nebudiriro zvesainzi. Vazhinji vanodavira kuti huru harizi kukura mashoko. Asi imbofungidzira hwako upenyu pasina maindasitiri zvivako! Muupenyu hwezuva nezuva, zvose Makomborero yebudiriro: mvura, magetsi, gasi, kupisa - uye haagoni kufungidzira upenyu pasina pavo. Kuti anunure mvura uye gasi, mvura uye gasi mapaipi muri kuvakwa kuti kushumira sezvo motokari.

Kana kuwedzera vavaki zvinoshandiswa gasi mains pombi. Zvakakosha kuziva kuti ivo rutivi hwedu hwezuva nezuva uye kugara chinokosha nzvimbo somunhu pasi mari achishandisa chokuendesa mvura uye magasi.

Chii chinonzi nenyere?

Panguva iyoyo, hapana mhinduro chete kuti mubvunzo uyu. Vakawanda tinogona kutaura kuti mutopota - icho nyaya kuti gadzira mhango Profile, iro rinoshandiswa nokuda chokufambisa negasi, mafuta, mvura siyana, kuputira, chisimbiso.

kupatsanura pakati pombi

Musono pombi kuna akakungurutsirwa (inopisa uye kutonhora rinopfungaira), chakatsikirirwa (dhayamita 820 mm) vakakandira (simbi uye simbi, dhayamita 900 mm).

On the Profile chikamu kusiyanisa zvitarisiko, kumativi:

• Square.

• Rectangular.

• Oval.

• chidimbu.

• Ribbed.

• teardrop serin'i.

• six-, mashanu uye octagonal.

kuzivikanwa nokuda longitudinal chikamu:

• Tapered.

• akapindira pamwe kugumbuka miromo.

Izvi hazvisi mazita rwose sepombi zvakasiyana muna longitudinal ndege. Ari oga boka vari bimetallic, trimetallic, zvinosanganisira vanoverengeka simbi akaturikidzana, ayo zvakabatanidzwa pamwe chete nomoto, akakonzera kubatana kwe kana nokusima.

Kushandiswa musono pombi

Pahwaro pakugadzwa anowanikwa:

• mafuta uye gasi indasitiri;

• Construction;

• muridzo unoridzirwa;

• Mechanical Engineering;

• midziyo uye dzehondo.

Zvikwepa nokuti mafuta uye gasi indasitiri yakagadzirwa kabhoni uye chiwanikwa steels. Chibooreso nyere rinoshandiswa zvakanaka kuchera uye operative njere. Casings inoshandiswa kuchengetedza masvingo gasi, mafuta zvakanaka ngura ingress pamusoro Urume kuparadzana nemumwe uye gasi reservoirs. Zvikwepa nokuti mapaipi akashandiswa chokuendesa gasi, mafuta, peturu, mvura, acids. Tubing inoshandiswa kuchera matsime kushanda apo oiri kunoitika, uye Threaded kubatana. Bhaira sepombi akashandiswa boilers-siyana mazano. chikuru nepombi iri kugadzirwa zvakafanira GOST 3262-75 uye welded. Pipe kuvakwa maererano GOST 800-78, 8642-68 rinoshandiswa zvaAtemisi siyana muchina zvikamu ndege engineering, kuti tarakita. Zvikwepa cracking walnut, maererano GOST 550-75, akaita hwendarira 10, 20, K5M, K5 12MH nevamwe uye rinoshandiswa kupomba mafuta mukuru kumanikidzwa.

mutopota hunde

The chikuru chepfungwa geji nenyere dhayamita yakakura, sezvo vari kushandiswa kuwedzera zvivako siyana kuvaka, kutakura mafuta, peturu, chiutsi, mafuta, gasi uye mvura.

Hunde simbi nenyere uye zononoka-welded kugadzirwa, dhayamita 529-2560 mm uye rusvingo Ukobvu 8-25 mm. Pombi kuti gasi mains dzinoitwa kushanda kungatikanganisa runyararo, panguva yakakwirira kumanikidzwa uye akaoma okunze. Nokudaro, nzvimbo huru munzvimbo mafuta uye gasi kuNorth reRussia necessitates kuvaka simba hunde mapaipi iri pasi pevhu.

Zvakandiomera okunze kumanikidza chaizvo yakakwirira yaanoti kunaka zvikwepa zvavo operative zvivako - simba uye plasticity unhu. Dzimwe nguva gasi nenyere hunde ane unhani: rinoumba, zingi, bituminous.

National Association ngura Engineers (NACE) wakasika mwero kuti anoita bvunzo uye kurumbidza kuti nezvinhu husingakwanisi kunyorovesa rehydrogen sulfide runyararo. Nzira zvekuongorora ari suitability kwemashoko; nguva kukundikana uye chikumbaridzo voltage.

Nokuti chubhu zvinhu, izvo zvinoshandiswa zvakakomba okunze, zvakakosha kuderera kuti tembiricha panguva iyo brittleness yacho simbi kunoitika, nani viscous ehupfumi ayo, izvo zvakatemwa specimens ane raundi incision pamwe risingamboshandisi tembiricha kuti -60 ° C, uye panguva yakadereresa zvinobvira ivhu unopinza notch uchishandisa tembiricha -20 ° C. Ndokusaka zvichikosha kushandisa pfungwa pombi chakaitwa GOST kana TU.

Muzongoza chubhu: Standard uye Magadzirirwo

Kusiyanisa chikuru nepombi ne:

1. Method pamusoro nomoto:

• Nemishonga nomoto.

• Arc nomoto.

2. Mhando weld:

• Spiral.

• longitudinally welded.

3. Chinangwa:

• Zvikwepa nokuti huru mapaipi.

• Zvikwepa kuti gasi mains.

• pombi kuti hunde mapaipi nevamwe vezvenhau.

4. dhayamita:

• pombi makuru dhayamita.

• pombi kuti dhayamita duku.

Zvakakosha kuyeuka kuti chinhu chakakombama nomoto - nzira inoshanda, uye kuonana mhando nomoto rinoshandiswa chete huru nenyere duku dhayamita. Pipe gasi Mapaipi makuru dhayamita ndiko tortsovannoy, pamwe cheek vanobviswa. Kana nenyere haisi tortsovannaya, cheek hadzina kubviswa pakati fekitari.

GOST 20295-85 - ndiyo huru pamutemo gwaro iri huru pombi.

Nenyere hunde: Gauge

Sezvo blanks kuti kugadzirwa imwe simbi mutopota muzongoza ubvise simbi rinoshandiswa, mashoko iro protrude zvikuru yakapambadzirwa kabhoni (kunyarara, Semi-vakaurayiwa) simbi uye pasi chiwanikwa simbi inopisa rinopfungaira.

Steels kushandiswa pakugadzira chikuru nepombi:

• 10;
• 20;
• 09GSF;
• 10G2FBYU.

Pipe muzongoza electrically GOST 20295-85, TU 14-3-1573-96:

Sezvinogona kuoneka, chikuru nyere yakashandiswa kunzwisisa Geological uye okunze, kungatikanganisa runyararo uye kugadzirwa maererano GOST uye TU, hombe musanganiswa chete akasimbisa nzvimbo pakati dzimwe pombi nepombi simbi rinopfungaira.
