Ukufakwa Kwepayipi Elinentambo

Ukufakwa kwamapayipi anentambo kusetshenziswa ezinhlelweni zamapayipi lapho auxhumano lwemishinikukhethwa kune-welding, ikakhulukazi-emigqeni emincane, ukuxhunywa kwezinsimbi, amagatsha awusizo, izindawo zokudonsa amanzi kanye nokukhipha umoya, kanye nemihlangano{1}}enobungani yokulungisa. Okufakwayo kwensimbi eyenziwe ngomgunyathi, isisekelo sokucaciswa esivamile siwukuthiI-ASME B16.11, eneziphetho ezinochungechunge ezitholakala kuI-NPT, BSPT, noma i-BSPP, ngokuvamile ukumboza1/8" kuya ku-4"namakilasi okucindezela njengeIkilasi 2000, 3000, futhi 6000.

I-fitting enentambo akufanele neze ithengwe ngomumo wodwa. Amaphuzu amathathu alawula ukwamukelwa yiwouhlobo lwentambo, isigaba sokucindezela, futhiIbanga lezinto ezibonakalayo.

Uhlobo lomucukufanele ifane nomdwebo wephrojekthi kanye nemakethe eyamukelayo:

• I-NPTisetshenziswa kakhulu kuwoyela, igesi, kanye nezinhlelo zezimboni ezijwayelekile zaseNyakatho Melika.
• I-BSPTfuthi intambo ecijile futhi isetshenziswa kakhulu ezimakethe eziningi zokuthekelisa.
• I-BSPPiwuchungechunge oluhambisanayo futhi ngokuvamile idinga iwasha yokuvala, igasket, noma ilungiselelo lendandatho ye-O- esikhundleni sokuphazanyiswa kwentambo yodwa.

Isigaba sokucindezelakufanele ifaniswe nezimo zomklamo womugqa:

• Ikilasi 2000
• Ikilasi 3000
• Ikilasi 6000

Izinketho zezinto ezibonakalayongokuvamile zikhethwa ngesimo sesevisi:

• I-ASTM A105yesevisi ye-carbon steel evamile
• I-ASTM A350 LF2ngesevisi-yezinga lokushisa eliphansi
• I-ASTM A182 F304 / F316ngesevisi{0}}engavimbeli ukugqwala
• I-ASTM A182 F11 / F22 / F91kumasistimu we-alloy aphakeme-ezinga lokushisa

Okwabathengi abaseshayoishadi lobukhulu bokufakwa kwamapayipi ochungechunge, okuqukethwe kwekhasi okuwusizo kakhulu akulona ithebula lekhathalogi engahleliwe-nezinombolo ezikopishiwe. Indlela esisebenzayo ukukhombisauhla lokukhethafuthi uchaze ukuthi isikhungo{0}}sokuphela{1}}sokuqeda kanye ne-geometry siqinisekiswa ngokumeleneI-ASME B16.11kanye nezinga elishiwo lomucu.

Ngobukhulu obuqondile, isilinganiso noma isibuyekezo somdwebo kufanele siqinisekise:

• uhlobo olufanelekile
• usayizi omncane
• isigaba sokucindezela
• intambo ejwayelekile
• Ibanga lezinto ezibonakalayo

A ukuhlanganisa ipayipi elinemicuingenye yezinto ezisetshenziswayo ezifojiwe ezivame uku-odwa kumapayipi amancane-abhobozayo. Isetshenziselwa ukuxhuma iziphetho zamapayipi anentambo ezimbili ngendlela eqondile futhi ibonakala kaningi ezinhlelweni ezisetshenziswayo, emagatsheni amathuluzi, amaphakheji e-skid, nomsebenzi wokushintsha ukulungiswa.

Ngokombono wokuthengwa kwempahla, amasheke abalulekile wokuhlanganisa ipayipi elinentambo yilawa:

• intambo ejwayelekile: NPT, BSPT, noma BSPP
• isigaba sokucindezela: 3000 noma 6000 kuvamile-ensizakalweni encane
• Ibanga lezinto ezibonakalayo: A105, LF2, F304, F316, njll.
• ikhwalithi yomshini: iphrofayili yentambo ehlanzekile kanye nokwamukelwa kwegeji efanele
• ukulandeleka: ukumaka kanye ne-MTR exhunywe kwinombolo yokushisa

Ukuhlanganisa ipayipi elinentambo kuzwakala kulula, kodwa uma uhlobo lwentambo lungalungile, ingxenye iba yinto engasebenziseki esizeni. Yingakho ama-oda okuhlanganisa kufanele ahlale ebhalwe ngefomethi ye-PO ephelele, njengokuthi:

Isibonelo:

I-ASME B16.11, inhlanganisela egcwele yochungechunge, 1 ku, NPT, Ikilasi 3000, ASTM A105, Qty ___

1/2 intshi yokufakwa kwepayipi elinentamboangabanye osayizi abavame uku-odwa kabusha kumapayipi amancane-abhorekile ngenxa yokuthi ahlala ebangeni lapho ukufakwa kubalulekile khona, kodwa ukwehluleka kokuvala okubangelwa ukulawulwa kabi kwentambo kusavamile. Kumaphrojekthi wangempela, lo sayizi usetshenziswa kakhulu ku-hook yensimbi{2}}imigqa ephezulu, ukuphindaphinda kwegeji yokucindezela, ukuxhunywa kwamavalvu ezimpande, izindawo zokudonsa amanzi kanye nokukhipha umoya, imigqa yamasampula, imigqa yokudonsa amanzi, amagatsha okudosa amakhemikhali, kanye nokuxhumana okuhlangene kwe-skid.

Emaqenjini okuthenga, lokhu akuyona into "encane futhi elula". Imvamisa ingelinye lamasayizi alula kakhulu ukulibukelwa phansi futhi elinye elishesha kakhulu ukudala izinkinga zenkambu uma ifomu lentambo, ukwenza imishini, noma ukukhetha kwekilasi kungalungile. Ukulinganisa okuyi-1/2 intshi kungase kubonakale kwamukelekile ngokubukeka, kodwa uma iukujula kwentambo, i-taper, i-pitch, i-crest finish, noma i-chamfer yokungenaayilawulwa kahle, izinkinga zokufaka zivela ngokushesha.

Okuvamile1/2 intshi yokufakwa kwepayipi elinentambozihlanganisa:

• ukuhlanganisa- ukuxhumana okuqondile phakathi kweziphetho zamapayipi anentambo ezimbili
• indololwane- ushintsho lwesikhombisi-ndlela ekugijimeni kwamapayipi ahlangene
• tee- i-branch outlet yamageji, ama-valve, kanye ne-utility take off-
• inyunyana- uxhumano olukhiphekayo lokulungisa{1}}imihlangano yobungane
• ipulaki- ukuvala izikhala ezingasetshenzisiwe
• isigqoko- misa ukuvalwa koxhumano oluxhumeke ngaphandle
• ingono- ucezu olufushane lokuxhuma olunentambo phakathi kwezinto ezifakwayo noma amavalvu
• i-threadolet- igatsha eliphuma kunhlokweni elikhudlwana liye emugqeni omncane-oborekile

1 intshi yokufakwa kwepayipi elinentambozivame ukusetshenziswa emigqeni emincane yezinqubo, ukushushuluza kwamakhemikhali, amasistimu omoya acindezelwe, amaluphu okuhlanza amanzi, kanye noxhumo lwamagatsha olukhiphekayo lapho ukufinyelela kokugcinwa kubalulekile. Lo sayizi uvame ukuba yindawo lapho abathengi beqala ukuqhathanisa hhayi nje uhlobo olufanele, kodwa futhiI-Class 3000 vs I-Class 6000, i-carbon steel vs insimbi engagqwali, ne-NPT vs BSPT/BSPP, ngoba ukufakwa manje kunomthelela oqondile ekuthembekeni kokuvalwa, ukuzinza kwegatsha, kanye{0}}nokusebenza kwesikhathi eside.

Ngokombono wokuthenga,1 intshi yokufakwa kwepayipi elinentamboakufanele i-odwe njengencazelo elula yento yesitoko. I-PO eqinile kufanele ichazeI-ASME B16.11, uhlobo olulinganayo, usayizi oyintshi engu-1, intambo evamile, isigaba sokucindezela, izinga lempahla, kanye nezidingo zokuhlola/zemibhalo. Eqinisweni, izinkinga ezivame kakhulu kulo sayizi ziyiukungafani kwentambo, ukubopha kwangaphambi kwesikhathi ngesikhathi sokuhlanganisa, nokulawula ukulandeleka okubuthakathaka, yingakho abathengi bevame ukunaka kakhuluukuqinisekiswa kwegeji yentambo, ukumaka, nokuqondanisa kwe-MTRngaphambi kokuthunyelwa.

Ukufakwa okunemicu yesevisi yokucindezela kuvame ukukhiqizwa kusukaizikhala zomgunyathi, kulandelwa umshini wokushisa nokushisa ngokusho kwebanga lezinto ezibonakalayo. Le nqubo ibalulekile ngoba ukusebenza kokugcina kokulinganisa kuncike kokungaphezu kosayizi wegama. Kuya ngokuthi:

• ubuqotho bentambo
• ukugxila
• ukujiya kwehlombe
• kwaba nokuqhubeka
• umngcele wengcindezi ongaguquki

Ukuze kuhlolwe,{0}ama-oda wokulinganisa amanani aphezulu kufanele afake:

• ukuqinisekiswa kwe-thread gaugeokwe-NPT/BSP
• ukuhlola kobukhuluezicini ezibalulekile
• isheke lokumakangosayizi, ibanga, ikilasi, nenombolo yokushisa
• Ukulandeleka kombiko wokuhlolwa kwe-MTR/mill
• I-MT / PTuma kudingeka
• ukuhlolwa kwe-hydrostatic noma i-pneumaticuma kucaciswe yi-PO noma i-project spec

Ukufakwa kwepayipi elinentambo kuwukufakela okufojiwe noma okungomshini okunezintambo zamapayipi zangaphakathi noma zangaphandle ezisetshenziselwa ukuxhuma ipayipi, amavalvu, izinsimbi, noma izitolo zamagatsha ngaphandle kokushisela. Ezinhlelweni zensimbi ezenziwe ngomgunyathi, izifakelo ezinentambo zivame ukukhiqizwa ukuzeI-ASME B16.11futhi ahlinzekwa ngezinhlobo zokuxhuma ezifanaI-NPT, i-BSPT, ne-BSPP.

Ngokuvamile zisetshenziswa lapho iphrojekthi idinga:

• umhlangano ngokushesha
• ukushintshwa okulula
• umsebenzi omncane oshisayo esizeni
• ukufakwa kwe-bore encane-okuncane
• ukunakekela{0}izakhiwo zamapayipi ezinobungane

Kumaphrojekthi wangempela, ukufakwa kwentambo kuvamile kuimigqa yezinsimbi,{0}}ukuxhumana kwegatsha levolumu ephansi, izinsiza, amadrayini, ama-vent,{1}}nemihlangano ekhweziwe ye-skidlapho ukuhlanganisa okusheshayo nokususeka kubalulekile.

Ububi obukhulu bokufakwa kwentambo ukuthiumphumela wokuvala uncike kakhulu efomini elilungile lentambo, umkhuba olungile wokuhlanganisa, kanye nendlela yokuvala efanele. Uma indinganiso yochungechunge olungalungile i-odwa, uxhumano lungase lubukeke lulungile ngosayizi kodwa luqhubeke lwehluleke phakathi{1}}nokuphakama noma ukuvuza phakathi nesevisi.

Izingozi ezijwayelekile zihlanganisa:

• Ukungafani kwe-NPT ne-BSP
• izintambo ezilimele ngesikhathi sokuthutha noma ukufakwa
• ukukhetha okungalungile kwesigaba sokucindezela
• indlela yokuvala enganele ezinhlelweni zentambo efanayo
• ngaphezulu-ukuqiniswa okulimaza uchungechunge
• amadokhumenti e-QA abuthakathaka abambezela ukwamukelwa

Lokhu akusho ukuthi ukufakwa kochungechunge akuthembekile. Kusho ukuthi bayadingaisiyalo sokucaciswa okungconokunalokho abathengi abaningi abakucabangayo.

Hhayi impela. Ekuziphatheni kokusesha kwezimboni,isisekelo sepayipi elinemicuyitemu elibanzi nelinganembe kangako. Kungase kubhekisele ku-aisisekelo sokukhweza, ingxenye yokusekela, i-floor flange-i-hardware yesitayela, isibani/i-railing hardware, noma insiza enentambo yesakhiwo, ngenkathi aukufaka imicuekuthengeni amapayipi ngokuvamile kusho ingcindezi{0}equkethe ingxenye eyakhiwe ibe sezingeni elichaziweI-ASME B16.11. Ngamanye amazwi, isisekelo sepayipi elinentambo kungase kube into esekela imishini noma i-hardware, kodwa ipayipi elifakwe ngentambo liyingxenyeumngcele wengcindezifuthi kufanele ikhethwe ngokulawula okuqinile kobuchwepheshe.

Lowo mehluko ubalulekile ekuthengweni kwempahla ngoba i-logic yokuthenga ihluke ngokuphelele. A iqinisoukufakwa kwepayipi elinentambokufanele i-odwe nguuhlobo olufanelekile, usayizi wegama, indinganiso yentambo (NPT / BSPT / BSPP), isigaba sokucindezela (2000 / 3000 / 6000), ibanga lempahla, kanye nezidingo zokuhlola / zedokhumenti. Itemu lokusesha elingacacile njengeisisekelo sepayipi elinemicuayimtsheli umphakeli ukuthi into iyi-aukuhlanganisa, indololwane, i-tee, inyunyana, ipulaki, ikepisi, noma i-threadolet, futhi ayisho lutho ngekilasi, indlela yokuvala, noma ukulandeleka. Empeleni, lolo hlobo lwamagama angacacile lungenye yezindlela ezisheshayo zokudala amaphutha engcaphuno, ukungafani kochungechunge, noma ukuthola ukubambezeleka.

Kumasistimu amapayipi, into kufanele ifane neingcindezi yesevisi, indlela yokuvala, nezinga lokufaka, hhayi nje isimo esibonakalayo. "Isisekelo" sesitayela sokusekela singase sidinge kuphela ukulingana kobukhulu kanye nokuhlonza izinto eziyisisekelo, kuyilapho i-fitting enentambo kufanele futhi yenelise.ukunemba kwentambo, isilinganiso sekilasi, ikhwalithi yokwenza imishini, ukumaka, nokulandeleka kwe-MTR. Uma imfuneko yangempela yephrojekthi iwukusebenzisa amapayipi ezimbonini, kusetshenziswa "isisekelo sepayipi elinentambo" njengoba igama le-RFQ lixega kakhulu; indlela ephephile ukubhala ingxenye njengendlela efaneleukufaka imicuincazelo.

Ulayini we-RFQ oqinile kufanele uhlanganise imininingwane eyanele ukuze ugweme ukungafani kochungechunge noma isigaba. Ifomethi esebenzayo ithi:

ASME B16.11 + uhlobo/iphethini yokufaka + usayizi + intambo evamile + isigaba sokucindezela + ibanga lempahla + ukuhlolwa/imfuneko yedokhumenti + ubuningi
