Ama-fastener wensimbi engagqwali

Kuyaphindeka futhi ukufudumeza futhi kunezinga eliphakeme le-fortility stackenless stackenless 304 kufanelekile ukuthi kungenye yemikhiqizo ethandwa kakhulu yezimboni etholakala emakethe. Zenziwe ngezinto zokwenziwa kwebanga eliphakeme futhi zitholakala ngosayizi nobukhulu obuhlukahlukene.

I-Carbon Insimbi Esetshenzisiwe ukuze kwazo. Lokhu okuqukethwe kungaba ngesimo sebha noma ngesimo sengoma yokuhlangabezana nesidingo sahlukene sokwakha. Banikela ngemishini ephezulu kanye nokushiswa.

I-ASTM 182 isetshenziselwa izinhlelo zengcindezi, kufaka phakathi ukufakwa kwezingcindezi, amavutha, kanye nezingxenye ezifanayo ezihambisana nobukhulu obucacisiwe noma amazinga obukhulu afana namakhodi we-ASME.

I-Hastelloy C-276 ama-bushings nawo asetshenziswa emithonjeni yegesi emuncu, ukugaxelwa kwamaphepha kanye nephepha, ukulahla imfucuza, imishini yokusebenza yemithi kanye nokudla. Ezinye izakhiwo ezibalulekile zale alloy nickel alloy c-276 ne-hastelloy C-276 zifaka ukumelana kwayo ku-oxidizing agents.

Lokhu kufaka phakathi ukufa nokufa kwazo, ukukhombisa kwamahhala nokusika izinqubo zokwakha ukwenza ukufakwa kwamapayipha.

I-Alloy 400 cishe ayivikelekile ekuqhekekeni kwe-chloride ukuqhekeka kokugqwala kokuqhekeka ezindaweni ezijwayelekile. Ngokuvamile, ukumelana kwawo ukugqwala kulungile ekunciphiseni imvelo, kepha mpofu emvelweni oxidizing.

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.

Njengoba nje izici zokuphikiswa zokugqwala zensimbi yekhabhoni zingathuthukiswa ngokuqhubeka kokuqhutshwa, kungenzeka ukwandisa izakhiwo zemishini zokufakwa kwe-ASTM A105 ngokusetshenziswa kwezindlela zokushisa.

Ngenxa yamandla ayo aphezulu kanye nokuqina kwezakhiwo, i-Incontel 800 iyi-alloy elungele ukuthola izinhlelo ezifunwayo kufaka phakathi ubunjiniyela bamasosha, i-aerospace, kanye nezimboni zokucubungula amakhemikhali.

Ku-ht Pipe. Sitshala imali kwimithombo ye-premium nobuchwepheshe obuthembekile kanye nemishini. I-NISPL inikeze umfutho ezimbonini ezimbalwa ngesikhathi seminyaka emithathu edlule, ngemikhiqizo yayo evelele kanye nezinsizakalo ezingejwayelekile.

I-ASTM A105, eyaziwa nangokuthi yi-carbon steel, iyi-alloy ye-iron-carbon nge-carbon yangaphakathi ye-carbon cishe ngamaphesenti amabili.

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.

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.

I-NAS625 (NCF625, UNS N06625) iyi-nickel-chromium-molybdenum alloy nge-niobium eyengeziwe. I-matrix ilukhuni enikezwe yi-molybdenum kanye ne-niobium imiphumela emandleni aphezulu. I-alloy imelana nezindawo eziningi ezinzima zokugqwala. Iphinde inikeze ukumelana namazinga okushisa aphezulu. Iphinde ikhombise ukuvikeleka okumangazayo ekugqwaneni nase-oxidation. Amandla awo okubekezelela ukucindezela okuphezulu kanye namazinga okushisa ahlukahlukene, ngaphakathi nangaphandle kwamanzi, kanye nokukwazi ukumelana nokuwohloka kwezindawo zenza kube yindlela efanelekile yezicelo zenuzi nezasolwandle.

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.

Imvamisa, ukwakheka kokuhlangana kwepayipi kuqukethe izinto ezifanayo noma ezifanayo njengoba amapayipi ajoyina. Ngokusekelwe kwinani lengcindezi yepayipi livezwa, lingahle liqine noma liketshezi, futhi lingaba njalo noma okwesikhashana.

Ukumelana nemidiya ehlukahlukene ewonakalisayo. Okuqukethwe kwe-Chromium kuhlinzeka ngokumelana okungcono ezimweni ezi-oxidizing kune-alloys 200 nango-201, kuyilapho u-nickel ephezulu enikeza ukumelana okuhle ekwehliseni izimo.

Sikhiqiza u-90 \ 1 10 Cu-Nitured izithuthi zepayipi ezilula ukuwela, kulula ukukhiqiza futhi zimelana nemvelo ne-biofouling.

I-ASTM A105 Socket Weld Fitting imininingwane yokunamathisela amapayipi lapho ipayipi lifakwe endaweni evuthiwe ye-valve, efanelekayo noma i-flange. Ngokungafani nokufakwa kwezinkuni ze-buttweld, ukufakwa kwezinsimbi zeSockel kusetshenziselwa ama-diater amancane amapayipi (amapayipi amancane afakiwe); Ngokuvamile amapayipi awo ububanzi bawo ama-NPS 2 noma amancane.

I-SS 304 Fittings asme SA182 304 Izici Ezingagculisi Ezenziwe Ngezinsimbi

I-HT Pipe ingenye yabenzi abaziwayo be-ASME B16.11 ama-bushings ahlanganisiwe, akhiqizwa ngezitayela ezahlukahlukene kanye nezinto zokwakha, adililelwe ukulingana nezinhlobonhlobo zezintambo ezijwayelekile nezikamile kanye nemihlangano enezinyathelo. Sinikeza ama-threaded hex ama-bushings anokumelana okuhle kakhulu ku-chloride ion ukuxabana kokuqhekeka kokuqhekeka, futhi abuye abuse ukumelana kahle nezinhlobonhlobo ze-oxidiziz.

I-Incons 718 iyi-alloy esuselwa ku-nickel esuselwa ku-nickel eyenzelwe amandla aphezulu okuvuthwa, amandla ashukumisayo kanye nezindawo zokuqhekeka ezivuka emazingeni okushisa aze afike ku-1300ºF (705ºC). Le alloy inokuzenzisa okuhle kakhulu.

Lolu hlobo lwensimbi luyakwazi ukubekezelela amazinga okushisa aphezulu, okwenza kube yisinqumo esihle sezicelo zezimboni. Kuqinile futhi, kuqinile, kanye nobufakazi. Ngaphandle kokuba nokulwa nokuphikiswa, insimbi engenasici angama-304 inezinga eliphakeme le-couctility kanye nokushaywa kwe-weldatiability.

Ukuthambisa okuvuselayo kuqala cishe ku-1600¡¡Ãf (871¡Ãc) futhi kuqediwe kahle ngemuva kwemizuzu eyi-10 kuye kwayi-15 yokushisa ngo-1800¡ãf (982¡ãc). Ngaphezulu kwalokhu kushisa, ukukhula okusanhlamvu kungaphikiswa, yize kunokushisa kafushane ngo-1900¡ãff kuzoholela ekuthayizeni ngokuphelele ngaphandle kokukhula okusanhlamvu ngokweqile. Njengoba izinga lokupholisa alinamthelela ekuthambisaneni, okuqukethwe kungaba khona amanzi aqediwe noma umoya kupholile.

Kusukela ngohlobo olulodwa kuphela lwe-carbon lensimbi echaza kuleli Zinga, i-A105 ibhekwa njengohlobo lwebanga lensimbi ye-carbon.

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

Izicucu zensimbi ezingenasici ziyizingxenye ezixhuma amapayipi kumapayipi, inhloso yazo ukuxhuma, ukulawula nokushintsha ukuqondiswa, ukuhlukanisa, ukusekela ukufakwa kwamapayipi okukhona, kuzinhlobo eziningi, izinhlobo, amamaki nokucaciswa ukuze uhlangabezane nezidingo ezithile.

I-Inconfel Inconto Okusetshenziswayo 625 okusetshenziselwa ukukhiqiza imikhiqizo ekulelizinga inamandla nobulukhuni obukhulu.

I-Alloy 600 akuyona i-Age Harding Alloy; Ukusebenza kubandayo ukuphela kwendlela eqinile etholakalayo.

Kususelwa kumafomu we-SW Tee, ukuphela kwegatsha kuzofakwa kowesilisa noma ngowesifazane. Ngakho-ke kukhona i-tee yegatsha labesilisa kanye ne-tee yegatsha labesifazane, lapho i-tube ngentambo ye-vpt yabesilisa, khona-ke i-tee izoba nemicu ye-NPT ye-NPT.

Ukwenza isakhiwo nokwakhiwa kwemigqa ye-stainless yensimbi ye-castings, okubaluleke kakhulu ezintweni zokusetshenziswa, ngoba izinga lokushisa nokupholisa akufani, okuphumela ekuhambeni okungahambisani. Ngamazinga okushisa aphezulu, umsebenzi we-athomu uqinisa futhi isigaba se- #ò siyancibilika, futhi nokwakheka kwalo kwamakhemikhali kuvame ukuba umfaniswano. Isakhiwo sesigaba esisodwa esifanayo siyatholakala ngemuva kokuphola ngokushesha.
