Pipe isiqu wegesi

Namuhla kunzima ukubona ngeso lengqondo izwe kanye nezimpilo zabo siqu ngaphandle impumelelo ngesayensi nobuchwepheshe. Abaningi bakholelwa ukuthi impumelelo eyinhloko ukuthuthukiswa kolwazi. Kodwa cabanga impilo yakho ngaphandle izindawo zezimboni! Ekuphileni kwansuku zonke, bonke bajabulela izinzuzo impucuko: amanzi, ugesi, igesi, ukushisa - futhi awukwazi ukucabanga nje ngokushiya impilo enethezekile ngaphandle kwabo. Ukuze ukuletha amanzi kanye negesi, amanzi kanye negesi amapayipi Kwakhiwa ukukhonza njengoba imoto.

Lapho obandayo abakhi esetshenziselwa igesi amapayipi amapayipi. Kubalulekile wazi ukuthi ziyingxenye yokuphila kwethu kwansuku zonke bese hlala isikhundla ebalulekile njengoba ongaphakeme izindleko esebenzisa ukulethwa uketshezi kanye amagesi.

Kuyini ipayipi?

Okwamanje, akukho impendulo eyodwa yalo mbuzo. Ngokuvamile singasho ukuthi ipayipi - kuba isihloko ukwakhiwa iphrofayela eziyize, esetshenziselwa ukuthuthwa igesi, uwoyela, uketshezi ahlukahlukene, ukwahlukanisa, ukuqinisa.

Ukwahlukaniswa amapayipi

amapayipi Seamless kangakanani iphuma (ugingqe ashisayo nabandayo), sicindezelwe (ubukhulu 820 mm) bese waphonsa (yensimbi nensimbi, ububanzi 900 mm).

On the kwesigaba iphrofayli ukuhlukanisa bobunjwa, round:

• Isikwele.

• kukanxande.

• Okusaqanda.

• Ingxenye.

• ribbed.

• unyembezi emise.

• ezineminyaka ephakathi kuka, amathathu- futhi octagonal.

zihlukaniswa kwesigaba longitudinal:

• tapered.

• Wagibela nge imikhawulo ecasukile.

Lokhu akulona lonke uhlu amashubhu ukuthi zingafani indiza longitudinal. Ngo iqembu ahlukene kukhona bimetallic, trimetallic, ehlanganisa izingqimba eziningana sensimbi, okuyinto axhunyiwe ndawonye yi-Welding, fusing noma zokutshala.

Ukusetshenziswa amapayipi Seamless

Ngesisekelo ukuqokwa ziyatholakala:

• uwoyela negesi umkhakha;

• Ukwakhiwa;

• piping;

• Mechanical Engineering;

• izitsha kanye amathangi.

Amaphayiphi uwoyela negesi umkhakha wenza carbon and ingxubevange lezinsimbi. Ukugubha ipayipi isetshenziselwa imishini kahle kanye intelligence zokusebenza. Casings asetshenziswa ukuze kuvikeleke izindonga igesi, uwoyela kanye ukugqwala ingress ngokwahlukana uketshezi nomunye futhi igesi amadamu. Amaphayiphi amapayipi esetshenziselwa ukulethwa igesi, uwoyela, uphethiloli, amanzi, acid. Tubing esetshenziswa imishini imithombo ukusebenza lapho umkhiqizo kawoyela senzeka, futhi threaded ukuxhumana. Boiler amashubhu elisetshenziswa boilers ka imiklamo ehlukahlukene. nephayiphu ekhiqizwa ngokuhambisana GOST 3262-75 futhi ashiselwe. ukwakhiwa Pipe ngokuvumelana GOST 800-78, 8642-68 isetshenziswa womshini ahlukahlukene izingxenye zemishini e izindiza ubunjiniyela, ka ugandaganda. Inqawe ngokuhlaziya, ngokuhambisana GOST 550-75, ezenziwe ngensimbi 10, 20, K5M, K5 12MH nabanye futhi lisetshenziswa ukumpompa uwoyela umfutho ophakeme.

ipayipi Wendlovu

Isici esiyinhloko ububanzi gauge ipayipi inkulu, ngoba zisetshenziswa lokukhuphula izakhiwo ezahlukene nasezakhiweni, uwoyela, uphethiloli, umusi, uwoyela, igesi namanzi.

Wendlovu steel pipe kanye Kuvunguza ashiselwe ekhiqizwa, ubukhulu 529-2560 mm kanye ukushuba udonga 8-25 mm. Amaphayiphi igesi amapayipi zenziwa ukusebenza ezindaweni onakalisayo, ngesikhathi ingcindezi ephakeme futhi ezimweni ezinzima zezulu. Ngakho, indawo ezindaweni eziyinhloko uwoyela negesi eNorth waseRussia kube nesidingo ukwakhiwa enamandla isiqu amapayipi elise ngomshoshaphansi.

kwezimo ezinzima zezulu abeke izimfuno eliphezulu kakhulu izinga amapayipi kanye nezici zabo nokusebenza - amandla futhi plasticity izici. Ngezinye izikhathi igesi ipayipi isiqu has a enamathela ekhethekile: esiyinhlanganisela, zinc, bituminous.

National Association of Corrosion Engineers (NACE) idale indinganiso ulawula ukuhlolwa kanye nezincomo wempahla ukuthi amelana ukumanzisa hydrogen sulfide ezindaweni. Isimo sokunquma nokuhlola efanelekile impahla: isikhathi ukwehluleka kanye voltage embundwini.

Ukuze impahla tube, ezisetshenziswa ezimweni ezinzima zezulu, kuba ukwehla ebalulekile lokushisa lapho brittleness we metal kwenzeka, ekuthuthukiseni izindawo zalo viscous, okuyinto zitholakala zezinhlobo nge imbobo isiyingi nge lokushisa okungenani -60 ° C futhi udangele kakhulu amasampula zingenzeka notch abukhali izinga lokushisa lokusebenza -20 ° C. Yingakho kubaluleke kangaka ukusebenzisa amapayipi main ezenziwe GOST noma TU.

Backbone tube: Standard kanye Imininingwane

Hlukanisa nephayiphu ngu:

1. Indlela Welding:

• Ukumelana Welding.

• Arc Welding.

2. Uhlobo weld:

• Kuvunguza.

• longitudinally ashiselwe.

3. Injongo:

• Inqawe for amapayipi main.

• Inqawe egesi amapayipi.

• amaphayiphi isiqu amapayipi nezinye abezindaba.

4. Ububanzi:

• amapayipi of ububanzi esikhulu.

• amapayipi of ububanzi ezincane.

Kubalulekile ukukhumbula ukuthi i-arc Welding - indlela jikelele, kanti imininingwane uhlobo Welding isetshenziswa kuphela nephayiphu ngenhloso ububanzi ezincane. Pipe wegesi sezimiso ubukhulu esikhulu tortsovannoy, nge burrs ziyasuswa. Uma ipayipi akuyona tortsovannaya, burrs kungukuthi isuswe futhi le mboni.

GOST 20295-85 - main idokhumenti zokulawula phezu amapayipi main.

Isiqu sawo ipayipi: Kala

Njengoba izikhala for ukukhiqizwa steel pipe backbone strip steel isetshenziswa, indaba okuyiwona aphume ashone carbon elixutshiwe kakhulu (ethule, semi wabulala) steel futhi ongaphakeme ingxubevange steel ugingqe ashisayo.

Lezinsimbi esetshenziselwa kukhiqizwe nephayiphu:

• 10;
• 20;
• 09GSF;
• 10G2FBYU.

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

Njengoba singabona, nephayiphu esetshenziswa ezimweni eziyinkimbinkimbi Geological futhi zezulu, ezindaweni onakalisayo futhi ekhiqizwa ngokusho GOST futhi TU, okunezinhlobonhlobo esikhulu waqinisa isikhundla phakathi kwezinye main ugingqe ipayipi lensimbi kuphela.
