Is kagesi-ashiselwe kanjani steel pipe?

Lapho ipayipi isetshenziswa namuhla, Steel kagesi-ashiselwe? Lo mkhiqizo, okuyinto ezimweni yesimanje kabanzi lisetshenziswe zimboni.

isicelo

Ngokuvamile, ibekwe lapho kuyadingeka ukuze bayise izidakamizwa liquid noma gaseous nge ngezinga eliphezulu of nolaka. Ngakho-ke, i-tube yalolu hlobo ingatholakala ubunjiniyela, laying main Ukushisa ungqimba.

Electric-ashiselwe steel pipe obusetshenziswa embonini. Ngaphandle-ke ungeke ukwenze ne yezinsiza uwoyela, ukwakhiwa, enkulu ekwakhekeni ifenisha noma ezemidlalo abaqeqeshi. yokusebenza kwalo ngezindlela eziningi, ukusebenza kuhle, amathuba amahle kakhulu Welding (kufaka ekhaya) ungakwazi ukuyisebenzisa izimo zokuphila ukuze kwakhiwe futhi ukulungisa amanethiwekhi zobunjiniyela.

Ubukhulu

Kagesi ashiselwe ngamapayipi ensimbi, esesikhundleni GOST 10704-91 inombolo, ukukhiqiza ezithile obuphelele okungahleliwe ububanzi ethile. Ngokwesibonelo, uma inani lokugcina 0.3 cm umkhiqizo akufanele kube ngaphansi kuka-2 budze, futhi uma lokhu mkhulu kunezinhliziyo 15.2 cm, ubude asikwazi ukuba ngaphansi kuka-5 m. Futhi, kunokwehluka ntathu lapho Ubude ububanzi inikezwe pipe ebangeni elithile. Ngakho, i-inkomba kuya ku-7 cm ubukhulu sihloko zingaba phakathi kwamamitha 5 kuya ku-9.

ukukhiqizwa

Yini izakhiwo ipayipi ezinjalo kufanele abe? Steel kagesi-ashiselwe ukuguqulwa ekukhiqizeni kumelwe abe nezilungiselelo ehambelana izidingo isimo izihloko esetshenziswa kule noma ukuthi sithombe. Ngokwesibonelo, amaphayiphi uwoyela negesi namapayipi (isiqu) kuthiwa yenziwa ngokuvumelana GOST 20295-85. Basuke ezakhiwe le arc Welding noma inhlobo oxhumana (okokugcina nge high-imvamisa imisinga) nge ezahlukene amandla amakilasi (kusuka K34 ukuze K60).

Ukuze womshini imikhiqizo esetshenziswa noma thermally iphathwa steel ashisayo iphuma (ekhululekile noma ephuma kabili wabulala) nge okuqukethwe C (carbon) akuyona ezingaphezu kuka 0.2% ngesisindo. amashidi walo bekufanele coiled tube, ngemva kwalokho imiphetho amashidi ashisayo zamanje ingcosana imiqulu (electrode izindandatho). Izinga izinqubo ezifana imishini ekhethekile kungaba ngempela high (amashumi amamitha ngomzuzu zokushisela ngamunye, kuye ngokuthi ukushuba odongeni). Umsebenzi cishe ngaso sonke isikhathi sihambisana ahlabayo imikhiqizo ubude oyifunayo usebenzisa imishini slotted.

Steel kagesi-ashiselwe ungathola ukwelashwa ukushisa like wonke obuphelele, futhi kuphela le weld. On base imikhiqizo metal awavunyelwe wanqoba, amaphutha uqhekeke, kwelanga futhi izinyanda. eyamukelekayo ezingeni ebusweni ukukhubazeka akufanele wakhuzwa Welding (ashanele kuphela) ukuze silondoloze degree edingekayo komkhiqizo nokwethenjelwa. amalunga omzimba ashiselwe akufanele Abanazo Fusion uqhekeke, ikhule ezimbotsheni, fistulas, slag inclusions okuyinto eza ebusweni.

izindleko

Ngokwazi ngamapayipi ensimbi umgwaqo kagesi ashiselwe? Intengo nabo, kuye ngokuthi umenzi, ebangeni steel, ububanzi futhi udonga ukujiya ziyahlukahluka kusuka 32 kuya kwezingu-45-48. Lapho uthenga ngaso sonke isikhathi kufanele unake ukulandelwa kwezilinganiso isimo, okungukuthi. Ukuze. Ngo nohlaka yayo, imikhiqizo ovivinyweni olubangelwa edingekayo, kuhlanganise ingxenye phuca, amandla umthelela ngaphansi kwamazinga ahlukahlukene okushisa, lo eqine esihlokweni okusaqanda, ukuphambuka obuphelele, izinga metal ashiselwe ngokuhlanganyela, nabanye.

Ukuze uthole ukwaziswa ngalokho umkhiqizo sihlelelwe ukuthenga, ungafunda kusuka uphawu tube. Kufanele ngempela athwale at ibanga 10-150 cm kusukela komunye umkhawulo, emakwe upende zihlanganisa unyaka ukukhiqiza, idatha control lobuchwepheshe, steel grade, inani ngabanye ipayipi (batch), uphawu umenzi.
