Amapayipi iphrofayela: usayizi. amapayipi iphrofayela Steel

Iphrofayela tube Ubukhulu okuyinto zivumelana GOST simele ukwehluka kohlelo steel ijabulise. imikhiqizo ezinjalo ifomu angajwayelekile, ngokuqondene cross-section. Uma iqhathaniswa nezinhloko-athikili nxazonke, Ingxenye evundlile tube ezimise sebenayo kobujamo obusaqanda, isikwele, unxande noma isikwele nge imiphetho oyindilinga.

Ububanzi bokusebenzisa

tube profiled, izinhlangothi zazo ingahluka, ayenzelwanga ipayipi kubekwa, kodwa efulemini yensimbi. tube elingenalutho has ukuqina efanayo induku zonke-metal, okuyinto yiqiniso endabeni lapho izilinganiso umkhiqizo kukhona okulingana izilinganiso ugingqe iphrofayli-metal. Uma lokhu esisindo eziyize angenqaba 40% uma beqhathaniswa-metal eyodwa. tube profiled, ogama Ubukhulu uvumele ukusebenzisa konke ukungenelela imiklamo kungenzeka, kunciphisa tindleko kanye nesisindo izakhiwo metal, kusale Ubukhulu ingashintshiwe namandla kwesakhiwo. Nokho, lokhu ukonga kwenzeka kuphela esimweni lapho ngokuhamba womshini imikhiqizo ezikhethekile elawulwa Ubukhulu.

Ukuthembela iphrofayela ipayipi osayizi

tube profiled, ogama Ubukhulu zinqunywa imingcele ezintathu, kuhlanganise nobubanzi, ukuphakama futhi udonga ukujiya, kungase kwenziwe indlela ethile. Kwezinga lemikhiqizo yezimboni, kukhona inqubo ezintathu zobuchwepheshe yokukhiqiza i ijabulise echazwe iphuma phakathi kwabo: ukusonteka ashisayo, ukusonteka abandayo, futhi eminye ukwakha iphrofayela emalungeni eziphothene. inqubo kwetheknoloji kuthinta indlela Samandla, udonga ukujiya kanye nezinye izilinganiso amashubhu.

Usayizi imikhiqizo hot iphuma

tube Shaped, okuyinto ungabona isithombe esihlokweni, kungase kwenziwe indlela esibandakanya ashisayo-technology. Indaba ukufuthelana ukwandisa plasticity, ngaleyo ndlela athole ukuma emkhonweni noma emkhonweni. Asongwe udini ezinamasondo banikele umkhiqizo ibe isiyingi kwesigaba tube nephrofayela ethize. Umkhiqizo semifinished ihlinzekwa e udini cindezela, eliveza round tube ibe wamaqhuqhuva, okusaqanda noma isikwele. Ngemva preform is selehlile, iphuma yi ezinamasondo. Uma, ngesikhathi ukukhiqizwa square iphrofayela ipayipi etholakala, isithombe is okusesihlokweni esithi, izinhlangothi kwesigaba akukwazi amamilimitha angu angaphansi kuka-60. Uma sicabangela gauge unxande izihloko zazo kunqunywa GOST 8645-68 ke osayizi okunjalo kuyoba mayelana 20. Inani elifanayo Ubukhulu ehlanganisa GOST 8639-82.

Owokugcina lezi zilinganiso isimo ukuchaza ubukhulu imikhiqizo ngephrofayela sikwele. Kuzo zombili lezi zimo Ubukhulu Sectional ziyahlukahluka kusuka 60 x 60 kuya 230 x 100 amamilimitha angu. Nokho, amashubhu ashisayo iphuma ngephrofayela square cross-section enikeziwe omunye Ubukhulu mkhawulo. Kulokhu kuba isikwele nge izinhlangothi 180 mm. Uma zingxenye ipayipi unxande kwatholwa ukusonteka ashisayo, inketho olandelayo, okuyinto kuthonywa ubuchwepheshe - iyona ukujiya udonga. Ngakho tube kungenzeka isikwele noma unxande, wathi ipharamitha akufanele kube ngaphansi kuka-4 kwangu. Ngokuphathelene ukushuba esiphezulu GOST 8639-82, kuba 14 kwangu.

Okwenyanga tube obuphelele

Pipe zingxenye unxande ungaba anobude obungalingani. Ngaphezu kwalokho, kungenzeka lesi sibalo yokulinganisa enikeza kokulingana obude obuthile, noma ukuvala-gage, okuhilela ekutholeni nemingcele ngaphakathi ingxenye. Futhi akunandaba ukuthi ifomu kuyodingeka usayizi yokugcina umkhiqizo we imikhiqizo ephuma kulo ngeke kushintshe. Ubude obuncane okulingana 4 m, kuyilapho seqiwe kuyinto 12,5 amamitha.

Ubukhulu amapayipi abandayo iphuma of

Steel iphrofayela ipayipi kungenziwa oluqanjwe ukusonteka abandayo kanye nobuchwepheshe. Ngenxa yalokho, kungenzeka ukuthola umkhiqizo elinendawo izici ezicashile ziqhathaniswa eyodwa eshisayo. I izici eziyinhloko enquma izakhiwo umkhiqizo, lokhu cross-section Ubukhulu nodonga ukujiya. Ubukhulu Sectional izivakashi asikwazi ukuba ngaphansi kuka-10 kwangu. Usayizi elikhulu onqenqemeni ingeqi amamilimitha angu-120. Ngakho, abandayo iphuma steel profiled tube ayikwazi unephrofayela kabani Ubukhulu zincane kunohlamvu 10x10 amamilimitha angu. Usayizi elikhulu esigabeni ngesiphambano ipayipi ezinjalo kuba 120x120 amamilimitha angu. Ngaphansi le ndinganiso ukulingana 17 osayizi, okungokwendlela GOST 8639-82 futhi, kanye 16 osayizi ejwayelekile, ezihlobene GOST 8645-68.

Cold iphuma lashukumisa iphrofayela ipayipi has a ukushuba odongeni 1 milimitha kuya kwezingu-8 kwangu. Kukhethwa imikhiqizo efana onesizathu ukuthi, uma kukhona isidingo umkhiqizo okuyinto elingenalo yaseZimbabwe, futhi izindonga mncane. Ubude amapayipi ezifana labo abenziwe ngesimo izingxenye ezincane, kuhluka 4 kuya ku-11 5 cm. A ubude umkhiqizo abandayo iphuma ekhiqizwa ngesimo izingxenye hhayi ntathu, kuhluka amamitha 1.5 kuya 9.

Ubukhulu of ashiselwe iphrofayela amapayipi

Izigaba ipayipi kungenziwa lashukumisa ashiselwe. Ngesikhathi esigabeni sokuqala amashidi preform ntathu, okuyinto ahlukaniswa steel ishidi. Ngaphezu kwalokho kusukela izakhi nalutho akhiwa izimisele futhi emva Welding umphetho wenziwa. Inqubo isebenzisa i igesi noma lokungeniswa ukuncibilika inert. Umphumela iphrofayela tube, intengo okuzokwenziwa esibalulwe ngezansi. Amandla ayo ngokomzimba musa ihluke izici Seamless imikhiqizo. High izinga umphetho uyakwazi athambise ukuqina we umkhiqizo ngo-% 10 kuphela. ukuqina encishisiwe kwenza kube nokwenzeka ukuba enze umkhiqizo kabani izindonga angase abe ukushuba kule ezahlukene 1 kuya ku 5 kwangu. Ubukhulu ngaleyo ndlela kungaba isukela amamilimitha angu 10x10 ukuze 100x100.

Ubude ashiselwe iphrofayli ipayipi

Shaped tube 40 * 40, kanye mkhiqizo nge ezahlukene cross-section ungase ube obuphelele ntathu volumetric. Esimweni sokuqala nobude sibekwa uhla kusuka ngamamitha 5 kuya ku-9. In the yesibili - inombolo ziyahlukahluka kusuka amamitha 1.5 kuya 9.

I amashubhu okusaqanda nge okweqanda cross-section

Ngaphezu Square kanye nemikhiqizo elingunxande, okukhiqiza weld zingenza tube okweqanda. Ubukhulu yabo zinqunywa GOST 8642-68. Ngokusho kwale dokhumenti, okudayiswayo amapayipi etholakalayo kungabonwa, izinhlangothi zazo ziyahlukahluka kusuka 16h10 kuya 90h32 milimitha. I ukujiya udonga izihloko ezinjalo kufanele yini engaphezu kuka-2.5 mm ngokuqondene inani eliphansi, kuba elilingana 1 milimitha.

okwenyanga tube izindleko kwesigaba isikwele

Uma unesithakazelo tube profiled, intengo yalo mkhiqizo kufanele ube nesithakazelo. Ngoba kufike umuntu mumbe imitha pipe, esigabeni sikwele uhlangothi 15 mm kungadingeka akhokhe ruble 94. Isisindo 1 imitha kulokhu 0,57 kg. Uma ingxenye umxhwele ngaphezulu 20x20, ngoba kuyodingeka bakhokhe ruble 147 / imitha. I ukujiya odongeni kuyoba 1.5 mm, isisindo imitha ngalinye okulingana 0.95 kg. 40 * profiled tube 40, nge ukushuba odongeni 1.5 mm ruble 296 imitha ngalinye. Ngokwandisa odongeni up 2 kwangu intengo antante ruble 377. Omunye imitha ukala kweyesi-2, 6 amakhilogramu. Lokhu kungaba ebalulekile lapho iyala ezokuthutha.

Iphrofayela amapayipi kwesigaba unxande 60x40 elibiza 344 ruble imitha ngalinye, okuyinto ezivumelekile odongeni ukushuba 1, 5 mm. Ukwanda ipharamitha wokugcina 2 kwangu kwandisa izindleko ruble kuze kufinyelele 493. isikwele 100 x 100 izindleko umkhiqizo 1377 ruble imitha ngalinye. Udonga ukushuba 3 kwangu. Kukanxande tube 100x50 ne udonga 3 kwangu elibiza 1007 ruble imitha ngalinye. Ungakhetha bona umkhiqizo, izinhlangothi zazo luhambisane nezinhloso. Iyatholakala lalimelela amashubhu eziningi ezinkulu profiled izigaba ezithinta budze lobehlukene, futhi udonga ugqinsi.

Isidingo ukulawula ubukhulu sephrofayela amapayipi

Abathengi ngizibuze ukuthi kungani Ubukhulu zibaluleke kangaka imikhiqizo sephrofayela, okuyinto ekhiqizwa ngezindinganiso isimo. Impendulo yalo mbuzo isibonelo ukusetshenziswa - amashubhu enjalo asetshenziswa ozimele ukuze ayifeze, ukuze ngisho ukuphambuka kancane izilinganiso kwesigaba engu- uyakwazi ukuba kulwenze buthaka yokugcina metal. Imikhiqizo, Ubukhulu zazo angahlangabezani namazinga isimo, angabizwa ngokuthi kuyingozi ngoba ukusetshenziswa kungaholela nemiphumela emibi uhlobo ukulimala lonke isakhiwo.
