I-Butt Weld Pipe Fittings

Ngezinhloso zezimboni, ezinhlelweni zamapayipi, sivame ukudinga ukuqondisa indlela yokuhambisa; lawula ukugeleza koketshezi (uwoyela negesi, amanzi, udaka); Vula noma uvale amapayipi, njll. Ngakho-ke, ukufeza le misebenzi, kuzosetshenziswa amapayipi ensimbi.

Insimbi ye-carbon efudumele bese yenziwa imishini ekufakweni kwensimbi ekhethwe. Ama-Fittings we-ASPHOTE SCEMET ASTM A105 asetshenziselwa i-Ambient- kanye nensizakalo yokushisa ephakeme kuzinhlelo zokucindezela.

Sinikeza amasosi, ama-sockets ensimbi, ama-sokets ensimbi engagqwali, ama-nickel alloy apokets, amasosi e-popper alloy, i-duplex steel, amasosi ensimbi ye-carbon kanye namasekeli ensimbi ye-alloy.

Insimbi engenasici futhi ayithathi hlangothi imvelo futhi i-inert, futhi isikhathi eside siqinisekisa ukuthi ihlangabezana nezidingo zokwakhiwa okuzinzile. Ngaphezu kwalokho, akusho ukuthi amakhompiyutha entela angaguqula ukwakheka kwawo lapho exhumana nezinto ezinjengamanzi.

Ngokwezinhlobonhlobo ezahlukahlukene kanye nezidingo zokufakelwa kwamapayipi, kwakha ukufakwa kwamapayipi ikakhulukazi kwamukela ukufa kwazo, ukukhombisa ukukhulula izinqubo.

Into ethokozisayo eyenza i-steel ¡®Stainless¡ss¡ i-chromium; Kodwa-ke, ukwengeza i-nickel enika insimbi engagqwali ukuba ibe yi-alloy eguquguqukayo.

Ukwelashwa Isixazululo kuyindlela evame ukwelashwa ukushisa okuvame kakhulu ngemuva kwenqubo yokuphonsa insimbi engagqwali. Isigaba se-carbide ngokuphelele noma sincibilike ngokuphelele ngemuva kokuthi insimbi engakhi ye-auntenitic ifudunyezwa cishe ngo-1100 ¡Ãc.

Bafakwa kanjani? Kalula: Ngakolunye uhlangothi, ukufakwa kwe-waldolet (isibonelo se-weldolet) kulungiswe kwipayipi le-Run nge-penetration groove egcwele futhi, ngakolunye uhlangothi, i-weldid (noma i-screw) kwipayipi yegatsha. Kuyiqiniso, ipayipi lezinhloko lizosikwa ngokufanelekile endaweni lapho ipayipi lidinga ukufakwa khona.

I-Half coupling isetshenziselwa ukugcwala okuncane komkhumbi kusuka emkhunjini noma ipayipi elikhulu elibunjiwe. Ingahlanganiswa noma uhlobo lwesokhethi. Inesokisi noma intambo kuphela ohlangothini olulodwa.

Lokhu okucacisiwe kuhlanganisa amazinga wezakhi ze-carbon zensimbi ye-carbon, okungukuthi, ama-flanges, ukufakwa, ama-valve, kanye nezingxenye ezifanayo, ukuze zisetshenziswe ezinhlelweni zokucindezela ezimeni eziphakeme nezimo eziphakeme zokushisa.

Ngokungeziwe kulezi zinzuzo zemvelo, insimbi engenasici ibuye ibe yinhlobo ebukeka kahle, inhlanzeko ngokweqile, okulula ukuyigcina, ihlala isikhathi eside, inikeza kakhulu izici ezahlukahlukene. Ngenxa yalokhu, insimbi engagqwali ingatholakala ezintweni eziningi zansuku zonke. Idlala indima evelele embonini yezimboni eziningi, kufaka phakathi amandla, ezokuhamba, ukwakha, ucwaningo, umuthi, ukudla nezinto zokudla.

I-ASME B16.11 I-Throolet ingukuxhumana kwegatsha okuthandwa kakhulu: Igatsha lenziwa nge-welding le nto kuya kokuphuma kwepayipi le-Run. Imikhawulo ye-throclet idluliselwe ukwenza lula inqubo yokufaka insimbi, futhi ngalesi sizathu. UChoctolet ungowomndeni we-Butt Weld Fittings.

Ukufakwa okukhishwe yimikhiqizo eyenziwe ngamandla aphezulu kanye nezinzuzo zezindleko ezicacile ngamasu ajwayelekile wepayipi.

I-ASTM A105 (eyaziwa nangokuthi i-ASME SA 105) ihlanganisa izakhi ze-carbon ezingenamthungo ze-carbon zensimbi ebekwe ekusetshenzisweni kwezinhlelo zokucindezela ku-ambient kanye nensizakalo ephezulu yokushisa.

Izicucu zensimbi ezingenasici ziyi-tee fittings. Inezitolo ezimbili ezingama-90¡Ã angled kanye nongenayo eyodwa. Lokhu kufakwa kungenzeka kube nemicu emaphethelweni. Lezi zinto zezesekeli zisetshenziswa ezimbonini eziningana ezinjengokucwengisisa kawoyela, ukwelashwa kwamanzi namanye amayunithi okulashwa. Ama-Tee Fittings ayatholakala ngosayizi nobukhulu obuhlukile, kufaka phakathi amathayela aqondile, amatafula alinganayo, ukunciphisa amathayela, amatafula aguqukayo, amagatsha amagatsha abesilisa nabesifazane, nemvulokazi yabesilisa nabesifazane.

Ama-bushings afana namashubhu amancanyana asetshenziswa kakhulu emishini ngemishini ejikelezayo noma eshelelayo imisele ukwandisa ukusebenza kahle futhi anciphise ukudlidliza nomsindo. Ama-bushings angasetshenziselwa ukumba izinsiza ku-drill emis

I-ASME B16.9 iyindinganiso eyaziwa kabanzi embonini yezithako, ama-flanges, nama-valve asetshenziswe emapayipini. Ukucaciswa kwalolu hlobo lwe-Cover Cover, ukubekezelelana, izinto zokwakha, kanye nokumakwa kwezinhlobo ezahlukahlukene zemikhiqizo. Umkhiqizo owodwa osetshenziswa kakhulu yi-elbow, kanye ne-A234 wpb ende radius carbon carbow elbow ukukhetha okudumile.

Ukuba ngumkhiqizo we-trailer, ama-throughts enzelwe imibandela ethile ngokususelwa kwikhodi ye-Piping Code asme B31.3, ngakho-ke, ubukhulu buchazwa nomqambi. Kodwa-ke, i-MSS-SP-97 inikezela ngezidingo zobukhulu ze-standard 90¡Ã's self-ukuxhumanisa igatsha-ukuxhumanisa ne-butt, izinhlobo zokugcina zesokhethi

Ukuhlangana kwamapayipi, okusetshenziswa kumapayipi noma kumapayipi, ubude bamapayipi obufushane kakhulu noma ishubhu elinemicu yamapayipi esokhethi noma emaphethelweni avumela amapayipi alinganayo noma ahlukile ukuze ahlanganiswe. Ukuhlanganisa ukufakwa kwamapayipi okusiza ukunweba noma ukuqeda ukugijima kwamapayipi. Lokhu kufakwa nakho kusetshenziselwa ukushintsha usayizi wepayipi. Kusetshenziswa futhi ukulungisa ipayipi eliphukile noma elivuzayo.

I-ASTM A105 Fittangs ekhishwe ngezixazululo ezahlukahlukene zezengezo zezimboni. Umkhiqizo kubathengi abaseduze nabasendaweni yomhlaba wonke unikezwa ngamanani akhanga kakhulu. Umkhiqizo wenziwa ngokuya ngezimpawu ezijwayelekile ezivuselelayo zokusetshenziswa. Bajabulela ukuba nedumela elihle emakethe.

I-A105 izothathwa ukwelashwa okushisa (ukunqwabelana, okujwayelekile, ukufutheka, noma ukucima). I-A105 izovumelana nekhabhoni, i-manganese, phosphorus, isibabule, i-silicon, ithusi, i-nickel, i-chromium, okuqukethwe kwe-molybdenum nokuqukethwe kwe-khromium.

Ngokucaciswa okusebenzayo njengesiqondisi, kuyadingeka ukuthi lokho okufundile ukulandela izidingo ezithile. Kanye namandla okuvuselela futhi avunelwe, i-ASTM A105 Ellow kumele alandele izidingo zokucaciswa kwemininingwane efana nokuncishiswa kwendawo, ukugcwala, kanye nezidingo zobulukhuni.

Njengamanye amapayipi epokhethi, inendawo eyakhiwe ngesitebhisi, ngakho-ke ukufaka ipayipi kumagatsha e-tee bese kuhlangana ndawonye. Imvamisa isetshenziselwa amasistimu amancane amashubhu.

Ngokuphelele futhi okungasebenzi kahle, insimbi engenacala yinto ¡° eluhlaza ± par ubuhle. Eqinisweni, emkhakheni wezokwakha, izinga layo langempela lokutakula lisondele ku-100%.

Insimbi engenacala engama-304 i-radius radius elbow ine-radius ende kunobubanzi obungaphandle kwepayipi elifakiwe. Lezi zesekeli ziwela ngaphansi kwe-ASTM A403 Procation. Amadayimitha abo aqanjiwe aqala kusuka ku-1 \ 8 "kuya ku-48". Izindinganiso zalezi zinhlobo ze-ASME B16.9 ne-B16.28. I-304 insimbi engenasici 90 degree elbows ivame ukusetshenziswa ama-elbows.

Ukugcizelelwa kwale alloy kubekwa eqinisweni lokuthi kumelana kakhulu nezindlela zolaka zokugqwala. Ikakhulu, i-Incoloy 800 ikhombisa ukumelana okuphezulu kakhulu kwizinhlanganisela ezilonakalisayo ezibonwa ezindaweni ezinamanzi.
Ukufakwa okukhishwe yimikhiqizo eyenziwe ngamandla aphezulu kanye nezinzuzo zezindleko ezicacile ngamasu ajwayelekile wepayipi.

Insimbi engenasici kumele ibe okungenani i-10,5% chromium. Kuya ngebanga, kungaqukatha amazinga aphezulu aphezulu we-chromium, kanye nezithako ezengeziwe zokuqalisa njenge-molybdenum, nickel, titanium, i-aluminium, ithusi, i-nitrogen, phosphous noma i-pelenium.

Insimbi engenasici i-alloy yensimbi engamelana nokugqwala nokugqwala. Inama-chromium okungenani ayi-11% futhi ingaqukatha izinto ezifana nekhabhoni, ezinye izinsimbi nezinsimbi ukuthola ezinye izakhiwo ezifiselekayo. Ukuphikiswa kwensimbi engagqwali emiphumeleni yokugqwala kusuka ku-chromium, okwakha ifilimu nje engavikela lokho nokuzipholisa ekubeni khona komoya-mpilo

Incoloy alloy 800 (ANS N08800, W. NR. 1.4876) Ingabe impahla esetshenziswa kabanzi yokwakhiwa kwemishini edinga ukumelana nokushisa, ukumelana nokushisa, amandla, nokuqina kwesevisi kuze kube ngu-1500¡¡Ãf (816¡Ãc).

Inqubo yokushisa iyinqubo yokwelashwa ekushiseni okusetshenziselwa ukukhulisa i-actility futhi yehlise ubunzima bezinto ezibonakalayo. Lolu shintsho lobulukhuni kanye ne-fortility luwumphumela wokuncishiswa kwe-dislocation ekwakhekeni kwe-crystal kwezinto ezifakiwe. I-Anneling ivame ukwenziwa ngemuva kokuthola impahla eye yathuthukiswa noma inqubo yokusebenza ebandayo ukuvikela ukwehluleka kwayo kwe-brittle noma ukwenza kube lula ukuphatha kamuva.
