I-SA234 WPB Elbow yenziwa ngensimbi ye-carbon noma insimbi ye-alloy.

I-ASTM A234 WPB Elbow ingenye yezindlela ezisetshenziswa kakhulu zokufakwa kwamapayipi. I-elbow isixhumi esakhiwe njenge-elbow futhi ivumela ukuguqulwa okuqondiswayo ekuhambeni koketshezi.

I-Butt Weld Pipe Fitting yenzelwe ukuthi ifakwe kwisayithi ezindaweni zayo (ama) ukuxhuma amapayipi (s) ndawonye futhi avumele ushintsho kububanzi obuhle noma ngepayipi, noma ephepheni noma ekuphelisweni.

Amamaki e-Carbon Insimbi ye-Carbon ahlukaniswe ngezigaba ezintathu ezahlukene ezisuselwa kokuqukethwe kwekhabhoni enama-carbon sten amancane. Ama-Light Steel Hex Bolts ayisigaba esisetshenziswa kakhulu kuwo wonke amaqembu ensimbi yekhabhoni. Insimbi emnene threaded bolt alloys imvamisa iqukethe ngaphansi kuka-0.25% carbon ngesisindo. Njengoba lolu hlobo lwe-carbon lensimbi bolt alunakuqina ngomuthi wokushisa ukukhuthaza ukwakheka kweMferemu, i-alloy iyasebenza.

Ukukhokhiswa kwensimbi yekhabhoni, okwenziwe ngokuya nge-ASTM A105, ngokuvamile kusetshenziselwa izinhlelo zokusebenza zamapayipi. Lezi Izakhi ze-carbon zensimbi ze-carbon (kufaka phakathi ama-flangetes, ukufakwa, kanye nama-valve, njll) zisetshenziselwa insizakalo ye-ambient- kanye nensizakalo yokushisa ephakeme kuzinhlelo zokucindezela. I-A105N, ekhethwe nge-Suffix ¡° ±, ichaza ukuthi i-A105 Ethethelelwa izofakwa esimweni esijwayelekile. Uma ukuthethelwa kusetshenziselwa ukufakwa kwamapayipi kwezicelo ze-ASME BPVC noma i-ASME B31, okuqukethwe kuzoba okulingana okufanayo kwe-SA-105 noma i-SA-105N yayo. Ngamafuphi, ukwelashwa okushisa kokujwayelekile kwehlukanisa i-A105N kusuka ku-A105, noma i-SA-105N kusuka ku-SA-105. I-ASTM A105 Flange ukucaciswa kwama-flangese. Ukucaciswa kungafaka amamaki ahlukene wezinto ezingenangqondo zensimbi eyenziwe amafuvu. Ama-flanges angowokwelashwa kwe-carbon futhi ahloselwe izinsizakalo zokushisa eziphakeme.

I-ASTM A234 WPB Pipe Fittings Carbon Insimbi Elbows yenzelwe izinsizakalo zokushisa eziqondile neziphezulu

Ukuze udlulise ipayipi, kuyadingeka ukususa i-hose eqondile epayipini. Lapho usebenzisa amapayipi ahlukahlukene, kufanele kusetshenziswe amapayipi ahlukahlukene. Lapho kusetshenziswa ipayipi, i-elbow kumele isetshenziselwe ukushintsha usayizi wepayipi. Lapho u-bifurcating, ipayipi elinezindlela ezintathu i-Flange uxhumano olusetshenzisiwe lapho i-joint isetshenziswa ama-pipeline ahlukahlukene amahle, ukuze ifinyelele ekukhuliseni okuhlangene noma ukugcwaliswa okuhlangene okuhlangene noma ukukhishwa okusebenzayo okubandayo kanye nokuhlangana okubandayo okuhlanganisiwe kusetshenziselwa ukuxhumana kwepayipi. , Ekuxhumaneni kwamathuluzi ahlukahlukene, kukhona nezixhumi nama-plugs esigaba sensimbi.

Ibanga le-WPB liyinto evame kakhulu yamapayipi okushisa aphakathi nendawo aphezulu kulezi zindinganiso. I-W imele "i-weldable," p for "ingcindezi," b ye "grade B," no y for "amandla okuthela."

Onke amamaki e-ASTM A694 F42 azobe ephethwe ukushisa. Ukwelashwa kokushisa kwama-stonbon kanye namandla aphezulu aphansi ama-alloy aphansi angabandakanya ukwenza okujwayelekile, okujwayelekile nokugunda, noma ukucisha nokugunda. Ukwelashwa kokushisa kwensimbi ye-alloy kungafaka ukwelashwa okujwayelekile nokwelashwa kwezulu noma ukwelashwa kwezulu nokwelashwa kwezulu. Izinga lokushisa elinolaka kufanele okungenani libe yi-1000¡Ãf [540¡Ãc. Ukwelashwa kokushisa kwezulu kwama-ally steel kufanele kube ebangeni le-1000 kuya ku-1225 ¡f [540 kuye kwayi-665 ¡Ãc.

Ukwelashwa okungaphezulu: okujwayelekile (uwoyela okhanyayo (u-glow evikelayo

Ama-Flango ensimbi ahlinzeka ngokufinyelela okulula kokuhlanza, ukuhlola noma ukuguqulwa. Imvamisa ziza ngezimo eziyindilinga kepha nazo zingafika ngezindlela zesikwele nezinxantathu. Ama-flanges ahlanganiswe komunye nomunye ngokubopha futhi ajoyine ohlelweni lwamapayipi ngokushiswa noma ethangothini futhi aklanyelwe izilinganiso ezithile zengcindezelo; I-150LB, 300LB, 400LB, 600LB, 900LB, 1500LB no-2500lb.

I-A105 izolandela amandla ashubeni, amandla okuthela, ukunwebeka, ukuncishiswa kwendawo, kanye nezidingo zobulukhuni. Imihlahlandlela yokubuyiselwa emuva, ukulungiswa ngokufudumala, nokumaka komkhiqizo kunikezwa.

I-ASTM A515 Ibanga lama-70 Carbon Insimbi lisetshenziswa ezitshalweni ze-boiler zamakhemikhali nakumboni we-petrochemical. Kuyamelana ngisho nasekushiseni okuphezulu emkhakheni wohlelo lokusebenza.

Ngokusho kwe-ASME Boiler ne-Pressure Vessel Code, i-ASTM A420 WPL6 ayivunyelwe ukusetshenziswa ekwakhiweni kwama-boiler wamandla.

Lezi zindawo zokufakelwa kwamapayipi zifaka i-tee, ukuncipha okuhlanganisiwe, ukuncishiswa okungu-eccentric, 5d \ 6d bend, i-elbow, izinyunyana, ipayipi, i-Piple, i-Pires, i-Prescient Piprication for Service kumazinga okushisa alinganiselayo nawo aphakeme.

Lokhu kufanele kube yingxenye yohlelo lokuhambisa uketshezi (uwoyela, igesi, umusi, amakhemikhali, ...) ngendlela ephephile futhi ephumelelayo, amabanga amafushane noma amade.

Ama-Flanges, ama-Fittings, ama-valves nezinye izingxenye ezahlukahlukene eziyalelwe ubukhulu bezimboni noma ezindinganisweni zezimboni ezinjenge-MSS, i-ASME ne-API Ukucaciswa kufakiwe esikalini.

I-flange ingaba yipuleti lokumboza noma ukuvala ukuphela kwepayipi. Lokhu kubizwa ngokuthi yi-flange eyimpumputhe. Ngakho-ke, ama-flanges abhekwa njengezakhi zangaphakathi ezisetshenziselwa ukusekela izingxenye zemishini.

Lezi I-A234 WPBS SPS 80 Ellow nazo zitholakala ngohlobo oluthile lobukhulu. Inhloso yokusebenzisa i-ASTM A234 GR WPB Elbow ukushintsha ukuqondiswa noma ukugeleza ohlelweni lwamapayipi.

Ezinye izinhlelo zayo ziwukukhunjulwa kwamandla, imboni yamaphepha kanye nephepha, imboni yokushayela kawoyela yaphesheya kolwandle, amakhemikhali akhethekile kanye nemithi. Ezinye izinhlelo zokusebenza lapho kutholakala khona zisetshenziswa yi-condensers, ukuphathwa kwegesi, imishini yamakhemikhali, imishini yamanzi olwandle, imishini yezemithi kanye nabashisi bokushisa.

Lolu hlobo lwensimbi luyakhiwa ngo-1700 kuye ku-2200¡Ã Fahrenheit futhi kulandelwa ukucimana nokugunda. Lapho kwenzeka, izingxenye ezakhiwe ziphonswe phansi ziye ngaphansi kwe-1000¡Ã Fahrenheit, bese zivuselela ziye ku-1500 kuya ku-1700¡Ã♥ Fahrenheit, ezilandelwa yi-Slow-Furope.

I-ASTM A694 Carbon Insimbi iyibanga elijwayelekile kakhulu lensimbi yekhabhoni elisetshenziselwa ukuthuthukiswa kwebhande eliyindilinga. Okuqukethwe okwengeziwe kwekhabhoni ye-alloy kunciphisa i-dectity ngokwandisa amandla ashubile.

I-ASTM A234 (ASME SA234) iyincazelo ejwayelekile yekhabhoni ne-alloy yensimbi yamapayipi ngezinsizakalo zokushisa eziphakeme neziphezulu.

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.

Ukuze udlulise ipayipi, kuyadingeka ukususa i-hose eqondile epayipini. Lapho usebenzisa amapayipi ahlukahlukene, kufanele kusetshenziswe amapayipi ahlukahlukene. Lapho kusetshenziswa ipayipi, i-elbow kumele isetshenziselwe ukushintsha usayizi wepayipi. Lapho u-bifurcating, ipayipi elinezindlela ezintathu i-Flange uxhumano olusetshenzisiwe lapho i-joint isetshenziswa ama-pipeline ahlukahlukene amahle, ukuze ifinyelele ekukhuliseni okuhlangene noma ukugcwaliswa okuhlangene okuhlangene noma ukukhishwa okusebenzayo okubandayo kanye nokuhlangana okubandayo okuhlanganisiwe kusetshenziselwa ukuxhumana kwepayipi. , Ekuxhumaneni kwamathuluzi ahlukahlukene, kukhona nezixhumi nama-plugs esigaba sensimbi.

Sikhiqiza uhla olubanzi lwe-ASTM A234 I-WPB i-WPB Fittings ebelekile efana ne-ASTM \ ASME A234 WPB Reducer & A234 GR WPB Fittings, ASTM A234 GR WRC.

I-ASTM A105 Flange ingukucaciswa kweFlanges.Carbon Steel ASTM A105 Flange yenziwa ngensimbi ye-carbon noma ngensimbi emnene yensimbi.

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

I-ASTM A234 iyincazelo ejwayelekile yokufakelwa kwepayipi kwensimbi kufaka phakathi i-carbon ne-alloy yensimbi yezinsizakalo zokushisa neziphezulu zokushisa.
