Putorino kātua paipa hau

I teie mahana, he mea fifi ia feruri i te ao, me to ratou iho oraraa, kahore nga whakatutukitanga o te pūtaiao me te hangarau. He tokomaha e whakapono e te paetae matua ko te whanaketanga o te mōhiohio. Engari whakaaro tika koutou ora, kahore whakaurunga ahumahi! I roto i te ora rā, ia oaoa i te katoa i nga painga o te ao: wai, hiko, kapuni, wera - me te kore e taea te whakaaro te ora whakamarie kahore ratou. I roto i te tikanga ki te whakaora i te wai me te hau, e hanga te wai me te hau pipelines ki te mahi rite te waka.

A, no te whakapuru kaihanga whakamahia hoki mains hau paipa. He mea nui ki te mōhio e he wahi o to tatou ora mahana ratou ka noho i te tūranga nui rite te tikanga utu iti o te tuku o te wai me te hau.

He aha te mea he putorino?

I te kau, i reira he kahore whakahoki kotahi ki tenei pātai. I roto i te whānui taea tatou te mea e te putorino - ko reira he tuhinga o te hanga kōtaha tuwhera, e whakamahia nei mo te waka o hau, hinu, ngā wai, mātao, ngā.

whakarōpū o putorino

putorino koti e ki hurihia (awhiowhio wera, me te matao), e aki (diameter 820 mm), me te maka (rino, me te maitai, diameter 900 mm).

I runga i te wāhanga kōtaha wehewehe ngā āhua, tawhio:

• Square.

• Tapawhā.

• Porotītaha.

• Wāhanga.

• rarai.

• Roimata-āhua.

• six-, toru me te tapawaru.

kitea e te motu roa:

• te topetope.

• takahia ki pito pouri.

e kore ko te rārangi katoa o ngongo e rerekē i roto i te manureva wä roa tenei. I roto i te rōpū motuhake e bimetallic, trimetallic, arā, o te maha paparanga whakarewa, e kua hono tahi i te fehokotaki'anga, fusing ranei whakatō.

Ko te whakamahi o putorino tui

I runga i te pūtake o te whakarite he wātea ana hoki:

• te hinu, me te hau ahumahi;

• Construction;

• taiepa;

• Mechanical Engineering;

• oko me tāke.

Putorino ki te hinu, me te hau ahumahi hanga o te waro me te koranu steels. Drill putorino te whakamahia mō te kōhao pai, me te maramarama whakahaere. Casings e whakamahia mo te tiaki o taiepa o hau, hinu pai tomo ki te waikura o te wehenga inu i ia atu, me te hau Faarii. Putorino ki pipelines whakamahia mo te tuku o te hau, hinu, penehīni, wai, waikawa. Ngongo whakamahia i roto i te puna kōhao mahi ina e te hanga hinu wahi, a kua miro hononga. korere kōhua whakamahia i roto i nga kohua i o ngā whakaaro. hangaia putorino matua te i runga i te GOST 3262-75 me te paiherea. whakamahia putorino hanga rite ki GOST 800-78, 8642-68 kei roto i te hanga o ngā wāhanga mīhini i roto i te rererangi engineering, o tarakihana. Paipa hangai, i runga i te GOST 550-75, hanga o te parahi 10, 20, whakamahia K5M, K5 12MH me ētahi atu, me te te ki te papu te hinu pēhanga teitei.

putorino Trunk

He nui te āhuatanga matua o te diameter mehua putorino, mai e whakamahia ratou mo whakapuru ngā hanganga i roto i te whare, mo te kawe hinu, penehīni, korohū, te hinu, hau me te wai.

Kātua maitai putorino, me te tōrino-paiherea hangaia, diameter 529-2560 mm me te matotoru taiepa 8-25 mm o. E hanga putorino ki mains hau ki te mahi i roto i ngā taiao ha'iriiri, i te pēhanga teitei, me te i roto i ngā āhuatanga huarere uaua. Ko te kupu, ko te wāhi o te wāhi matua o te hinu, me te hau i roto i te Te Tai Tokerau o Russia necessitates te hanga o pipelines kātua kaha kei raro.

ngā takiwā makariri uaua tangohia titauraa tino nui i runga i te kounga o putorino, me o ratou āhuatanga whakahaere - te kaha me te plasticity āhuatanga. I te tahi taime hau putorino kātua he paninga motuhake: hiato, konutea, korotā.

hanga National Association o Corrosion Engineers (NACE) kua he paerewa e regulates te whakamātautau me ngā tūtohutanga mō ngā rauemi e te hunga ātete ki te maku taiao hauwai sulfide. Paearu mō te aromātai i te pai o te rauemi: te wa ki te kore, me te ngaohiko paepae.

Hoki te rauemi ngongo, e kua whakamahia i roto i te kino ngā takiwā makariri, he mea heke nui o te pāmahana i ai brittleness o te whakarewa puta, te whakapai ake ona āhuatanga Kaore, e kua whakaritea i runga i ngā tauira ki te kokoti porohita ki te pāmahana mōkito o -60 ° C, me te i te i raro tauira taea ki kakari koi pāmahana whakahaere -20 ° C. Ko te aha kia nui ki te whakamahi i te putorino matua hanga ki GOST TU ranei.

Tapahanga ngongo: Paerewa me Whakatakotoranga

Te wehe putorino matua e:

1. Tikanga o fehokotaki'anga:

• Ātete fehokotakianga.

• Arc fehokotakianga.

2. Momo o Weld:

• Koru.

• ōna paiherea.

3. Taumu'a:

• Paipa mō pipelines matua.

• Paipa mō mains hau.

• putorino ki pipelines kātua ki ētahi atu pāpāho.

4. Te whitianga:

• putorino o diameter nui.

• putorino o diameter iti.

He mea nui ki te mahara e te fehokotaki'anga pewa - he tikanga ao, me te whakapā momo o fehokotaki'anga te whakamahia anake mo te putorino matua ki te diameter iti. pūnaha putorino hau paipa o diameter nui he tortsovannoy, ki e nekehia atu burrs. Ki te kore ko te putorino tortsovannaya, e kore e burrs nekehia i roto i te wheketere.

GOST 20295-85 - ko te tuhinga ture matua i runga i te putorino matua.

Te kātua pipe: mehua

Ka rite ki reni mō te hanga o te parahi putorino tapahanga Unuhia maitai whakamahia te, te rauemi hoki e protrude waro tino patu (ata, āhua-patua) rino, me te iti koranu maitai awhiowhio wera.

Steels whakamahia hoki te hanga o te putorino matua:

• 10;
• 20;
• 09GSF;
• 10G2FBYU.

Putorino tapahanga electrically GOST 20295-85, TU 14-3-1573-96:

I taea te kite, putorino matua whakamahia i roto i ngā āhuatanga arowhenua me huarere matatini, taiao ha'iriiri me te hangaia rite ki GOST ko TU, he Whārangi nui whakakaha tūranga i roto i te tahi atu awhiowhio putorino whakarewa matua anake.
