Ukuboniswa kwefektri yamapayipi amaphayiphu 304 ama-elbows nama-a105 flanges

Singabakhiqizi, abahlinzeki kanye nabathengisi bamanye amazwe e-carbon steel A105 \ A105N FLANES, okuyinto, umphakathi waseMelika wokuhlola izinto ze-carbon-wensimbi, ezisebenza ezinhlelweni ze-carbon-steel ezinamazinga okushisa asekamelweni kanye namazinga okushisa aphakeme kunawo. Sikhiqiza i-carbon steel A105 \ 10 A105N Blind Flanges aphumelele ekuqothulweni nasekuthambekeni kwamapayipi ngezinhlelo zengcindezi ezinzima njenge-hydraulic systems ngoba zinengcindezi enkulu yokugoqa esikhungweni.

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.

Imigoqo eyindilinga ye-Carbon

Ukuze uthole ukufakwa kwamapayipi wensimbi okungenamthungo kubhekisele ekufakweni kokufakwayo okuqukethwe kusuka kumapayipi ensimbi engenamthungo namashubhu. Ngakho-ke ukufakwa kwamapayipi wensimbi e-welded kuhlanganisa izinto ezicijile eziluhlaza kusuka kumapayipi ensimbi afakwe ku-welded.

Ukucaciswa kwe-ASTM A234 kunamabanga amaningi, njenge-WPB, i-WPC, i-WP5, WP9 WP11, WP12, WP22, WP91 nokunye. Kukhona ingcindezi ye-ASTM A234 WPB Pipe Fittings ku-1 \ 2 amayintshi kuya kumasentimitha angama-24 abahlangene abanobukhulu obukhulu abanobukhulu obuhlukile odongeni oluhambelana namashejuli.

I-Weld Neck Flange (WN Flange) inamathisela ipayipi ngokufaka ipayipi liye entanyeni yepayipi i-flange. I-a ivumela ukudluliswa kwengcindezi kusuka kupayipi we-weld teat flanges kuya kwipayipi uqobo. Lokhu futhi kunciphisa ukugxila okuphezulu kwengcindezi esisekelweni se-HUB ye-Weld Tempter Flanges.

Umqondo wonke wokubuka i-Flange ye-Plind Fliectange yilokho umuntu angaqiniseka ngokuphelele ukuthi into yemishini ifakwe kahle futhi ingenakuphepha ngaphandle kokugeleza noma ukuvuza nge-valve ngesikhathi sokulungiswa. Imisebenzi efanayo nayo yenziwa nge-A516 grade 70 Spade blind, noma kunjalo imvamisa isetshenziselwa osayizi abakhulu bepayipi.

Ukufakwa kwama-LTCS A420 WPL6 Welld kumelana kakhulu namanzi olwandle nezindawo zasolwandle ezine-1 \ 8 amayintshi kuya ku-48 inches onobukhulu obukhulu abangama-intshi.

I-ASTM A234 WPBSS-Fittings ihlanganisa ukufakwa kwensimbi ye-carbon ye-welded futhi engenamthungo evikelekile ngokuchitshiyelwa kwakamuva kwe-Asme B16.9, i-MSS-SP-95, ne-MSS-SP-97, kanye ne-MSS-SP-97, kanye ne-MSS-SP-97, kanye ne-MSS-SP-97.

I-ASTM A234 Imboza i-Carbon Insimbi ye-Carbon kanye nokufakwa kwensimbi ye-alloy yezokwakha ezingenamthungo kanye ne-welded embozwe ukubuyekezwa kwakamuva kwe-ASME B16.9, i-MSS-SP-95, ne-MSS-SP-97, kanye ne-MSS-SP-97, kanye ne-MSS-SP-97, kanye ne-MSS-SP-97.

I-ASME B16.5 I-Standard Covers Insimbi Flanges ye-Steel Flanges kanye nokufakwa kwamapayipi okuvela ku-NPS 1 \ 2 kuya ku-NPS 24 metric

Ama-Flanges, ukufakwa, ama-valve nezinye izinto ngokucaciswa kwe-A694 alungele insizakalo yokudlulisa ingcindezi ephezulu.

I-SA350 LF2 FLANDS isetshenziselwa kakhulu ukuxhuma amapayipi, ama-valve namaphampu. Inamabanga namakilasi amaningana. Lokhu kungukumelana nokukhulisa futhi kusetshenziswa emikhakheni eminingi yezimboni. Zenziwe ngobukhulu obucacisiwe, noma amazinga abucayi, njengezincazelo ze-ASME ne-API. Ukwakheka kwezinto ezibonakalayo kufaka ikhabhoni, i-silicon, i-manganese, phosphorus, isibabule, i-molybdenum, ithusi, i-chromium, i-nickel, i-vagadium ne-niobium.

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.

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.

Imigoqo eyindilinga ye-Carbon Amabha we-Carbon Steel LF3 asetshenziselwa ikakhulukazi amabhuloho we-skyscraper kanye nokwakha umkhumbi. Izinduku ze-Carbon zensimbi ye-LF3 Threaded zivame ukusetshenziswa emishini yezemithi. Amabha omjikelezo we-Carbon

Imikhiqizo ejwayelekile ye-A234 WPB Pipe Fittings iyi-elbows, tee, ama-cap, ama-cross.

Ama-fasteners ensimbi ye-carbon ajwayele ukuhlanganiswa nge-PTFE yezimboni (emfushane ye-polytetrafluoroethylene) kuzinhlelo zokusebenza ezidinga amandla aphezulu nokuphikiswa kokugqwala futhi asebenza ngokomnotho. I-Sae-Aisi 1018, 1020, 1045 \ CK45 amamaki ajwayelekile e-carbon asetshenziselwa ukukhiqiza la ma-fasteners. Ukucaciswa Kwezimboni okufana ne-ASTM A36, A193, A194, A154, A554, A540, A540, A540, A540, A540, A549, F1554 no-SAE J429 amboza ama-High Carbon Carbon Carnon Tecker Amabanga.

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