Izinto zokwakha

Ngaphezu kokuthembeka, inamandla amakhulu okubekezelelana. Izicucu zethu ezingenasici ezingama-304 zikhiqizwa kusetshenziswa ubuchwepheshe besimanje kanye nezinto zokwakha ezisezingeni eliphakeme eziqinisekisa ukuhambisana namazinga aphesheya.

Ukushisa ukwelashwa okufakwayo kwe-ASTM A105 akuyona imfuneko yokuphoqelela. Yize kukhona okuhlukile kwama-flanges anesilinganiso sokucindezela se-ASTM A105 ngenhla kwekilasi eliphakeme.

Ama-ASTM A105 Fittings athuthukile anzima, akhudlwana futhi ahloselwe ukusetshenziswa okusindayo kwezimboni. Yakhiwa ngensimbi etholwayo yekhabhoni. Ukukhokhisa inqubo yensimbi kwenza ukuthi kufaneleka kakhulu. I-carbon yensimbi ifudunyezwa emazingeni okushisa ancibilikisiwe futhi ibekwe ekufeni.

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.

Ukufakwa kwamapayipi kwe-ASTM a105 kusetshenziselwa ukufaka noma ukulungisa amapayipi noma amasistimu we-tubing adlulisela uketshezi, igesi, nezinto eziqinile ngezikhathi ezithile. Ukufakelwa kwe-SA 105 kuza ngosayizi abahlukahlukene ukuze balinganise ipayipi bazoxhuma. Kuyasiza ukuhlanganisa, ukuphambukisa noma ukunciphisa ukugeleza kokuhlinzekwa kwamanzi.

Isibonelo, ukusetshenziswa kwe-Carbon Steel Astm A105 Fittings kuvelele kulezo zinhlelo zokusebenza ezingahileleki hhayi izindawo kuphela lapho amazinga okushisa ephakeme khona, kodwa futhi nakulezo zinhlelo zokusebenza ezishisa egumbini lokushisa.

Imvamisa, lezi zinhlelo zokusebenza ziyizinhlelo zengcindezi, futhi zibonakala ezimweni eziningi, ama-ASTM A105 Threaded Fittings afaka inani kuhlelo lokusebenza olushiwo.

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

Ukucaciswa ngakunye njenge-ASTM A105, kusetshenziswa izindlela ezifana nokufaka impahla ukuze zisebenzise izinto ezijwayelekile, ukunxusa, ukufutheka noma ukujula kungaletha ushintsho olubonakalayo ezingxenyeni zemishini ye-ASTM A105.

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.

Ukufakwa kwensimbi okwenziwa ngensimbi kungayalwa ukuthi kuhlangatshezwane nezidingo zamakhasimende ngokuthola ngokwenziwe ngokwezifiso ngokuya ngobukhulu obufundisiwe. Ubukhulu be-ASTM A105 Fittings nabo buyatholakala ngokwezithelo zezimboni ezinjenge-MSS, i-ASME ne-API Procation. Ukucaciswa kwe-Fittings ye-A105 kunesilinganiso esifinyelela ku-10,000 lbs.

Ama-Flango wethu we-WNR 2.4856 agcina amandla phezu kwebanga lokushisa elibanzi, eshaya izinhlelo zokusebenza zokushisa eziphakeme lapho insimbi ne-aluminium kungavuselela ama-sneakby asho izikhala ze-crystal. Lokhu kutholakala kumakhasimende ethu abalulekile kububanzi obuhlukile wamadayimitha, ubukhulu bodonga nosayizi ngamanani ashibhile.

Njengenhlangano ehlonishwa kakhulu emakethe, thina njengoba u-Rexten ehlanganyela ekuphakamiseni iqoqo le-Informel Flanges njengomthengisi, umenzi, umphakeli, kanye nokugcina okuhlangene namaklayenti ethu emhlabeni jikelele.

Abafakizicelo abaphambili be-Alloy 625 Flongele bafaka izimboni ezinjengezimboni zasolwandle kanye ne-petroleum. Ezinye izinzuzo zokusebenzisa ama-contel 625 Flanges afaka ubulu bokuqhekeka obuphezulu kanye nokwakheka.

Ama-Flanges angama-625 angama-625 angu-nickel amelana no-nickel anamandla futhi aqinile anama-nickel angama-58% kanye nama-20% chromium, ikhabhoni, i-manganese, i-silicon, isibabule, ithusi nensimbi. I-Flange impahla inamandla ashubile angu-930MPA kanye namandla okuvutha we-517MPA.

I-ASTM B564 Incontel 625 Flanges inesilinganiso esiphakeme sokwakheka, ngenkathi ikhombisa ukushiswa okungcono ngokuqhathaniswa nezinye izinto eziningi ezisekelwa yi-nickel.

Amandla amancane wesivuno ama-flanges angama-517MPA kanye namandla amancane ashubile angu-930MPA. Lawa ama-flanges aphezulu aphezulu aqhathaniswa nama-flanges ensimbi engagqwali. Amandla aphezulu e-InconLel Alloy 625 aspling on Flanges kanti ezinye izinhlobo zivela ekwakhiweni kwezinto ezibonakalayo. Okuqukethwe kwenziwa ama-nickel angama-58%, ama-chromium angama-20%, ikhabhoni, i-manganese, i-silicon, isibabule kanye ne-5% iron. Okuqukethwe okuphezulu kwe-nickel kanye ne-chromium kwenza ama-flangese amelana kakhulu nokuqina.

Ama-Flanges a-Alloy angama-625 izimpumputhe nezinye izinhlobo futhi zinendawo ephezulu kakhulu yokuncibilika yama-degrees angama-1350 Celsius. Indawo ephezulu yokuncibilika ivumela ama-flanges ukuthi asetshenziswe kuzinhlelo zokusebenza zokushisa eziphakeme kanye namandla avumela lezi zicelo eziphezulu zokucindezela.

Kunezinhlobo ezahlukene ze-flanges ezinjenge-alloy 625 slip on flange nabanye. Zonke lezi zinhlobo zingezokwazisa nge-ASTM B564 zeNickel Alloy, Inxote, Monel kanye neHastelloy Falnges.

Usayizi usukela ku-1 \ 2 amayintshi amasentimitha angama-60 ngokuya ngohlobo lwama-flanges.

I-HT Pipe iba ngomunye wabakhiqizi abaholayo nabathembekile be-ASME SB564 Incontos grade 625 Flanges eMumbai, e-India ngokuhlinzeka ngemikhiqizo esezingeni eliphezulu kakhulu kumakhasimende ethu. Sihlinzeka ngamanani afanele afaka izaphulelo ezinkulu ngokumelene nohla lwama-contel alloy 625 Flanges.

Izixhumi ze-Carbon zensimbi Flange nezixhumi ze-Flange ezenziwe ngokuyisisekelo ngensimbi yekhabhoni. Amazinga ajwayelekile afaka i-ASTM A694, ASTM A105N (SA105n), i-MSS SP-44, DIN 2533. Izilinganiso zengcindezelo ezihambisana ne-Class 150 kuya ku-2500.

Njengoba okuqukethwe kwe-carbon element kukhuphuka, insimbi izoba nzima futhi ibe namandla ngemuva kokwelashwa okushisa. Ngokuphambene nalokho, kube yinhle. Kulapho uma kungekho khona ukwelashwa okushisa, i-carbon ephakeme izokwehlisa ukufudumala.

I-Carbon Steel ingafaka ama-alloy ensimbi uma kungasetshenziswa njengensimbi engenasici.

Ama-flase e-Carbon iron ajwayele ukwamukela insimbi emnene noma insimbi ephansi yekhabhoni, ngoba ifaka amaphesenti amancane ekhabhoni, eqinile futhi enzima kodwa anothuli kalula. Okuthi ngezindleko eziphansi nezinto ezibonakalayo ezingasetshenziselwa izinhlelo eziningi.

I-ASTM A105 I-Steel Light Light impahla ejwayelekile (i-carbon yensimbi emnene) ye-carbon steel flange, isetshenziswe ezindaweni eziningi zensizakalo ephakeme kanye nezinga lokushisa eliphakeme ezinhlelweni zokucindezela.

Lokhu okuqukethwe kuhlala isikhathi eside, kubiza okuphansi, futhi kunzima ukuphula. Uma kwenzeka kusetshenziswa ohlelweni lwamapayipi ensimbi olungenasici luzoguqulwa ngendandatho ehlanganyelwe ye-LAP.

Yakhelwe ngqo ukusetshenziswa kwezinga lokushisa okuphansi, leli banga lensimbi yekhabhoni lihlanganyela ukufana okusondelene nebanga le-ASTM A105N (SA105n). Leli banga lidinga ukuhlolwa kokuqina kwe-notch, futhi kusebenza kwizimboni eziningi.

Izindinganiso ezibekwe i-ASTM A694 zilukhuni ukwedlula lokhu okungenhla. Izidingo zayo zokudluliselwa kwamanzi okuphezulu kwengcindezi yamafutha kawoyela negesi kuyahlanya. Ngenxa yezimo eziqinile ngebanga lensimbi, abakhiqizi kufanele bathuthukise insimbi eqine kakhulu kuwona womabili amazinga okushisa aphansi kanye namazinga okushisa aphezulu.

Ama-flanges ensimbi ye-carbon akhiqizwa ngokwenza noma ngokuphonsa.
