Ipayipi le-ASTM A333 Grade 6

I-ASTM A333 Ibanga lesi-6 imboza amapayipi ensimbi angenamthungo nashiselwe asetshenziswa emazingeni okushisa aphansi afika ku- -50℃F (–46 degree).

Insimbi yakhelwe ukugcina ukuqina ngaphansi kwezimo ezingaphansi, isekela ukuqukatha kwengcindezi ephephile kanye nokuzinza kwesakhiwo kumasistimu e-cryogenic afana namatheminali e-LNG, izimboni zokucubungula igesi, kanye nengqalasizinda yamapayipi e-arctic.

Izici zokusebenza ezibalulekile:

• Ukumelana nokuqhekeka ngaphansi kokufinyela okushisayo
• Amandla azinzile phakathi nemijikelezo yokuqala ebandayo
• Ukushisela okuthembekile ekufakweni kwenkambu
• Ithobela{0}}amasistimu engcindezi ye-ASME ephansi

I-sulphur ephansi ne-phosphorus kuthuthukisa ukuqina kwe-notch emazingeni okushisa aphansi.

U-Charpy V-Ukuhlolwa kwe-Notch kuqinisekisa ukumelana nokuphuka kwe-LNG nesevisi ye-arctic.

Amapayipi e-ASTM A333 eBanga lesi-6 akhiqizwa njengangenamthungo noma njengamapayipi ashiselwe, kodwa kuzo zombili izimo inqubo ihlelwa ukuze ihlangabezane{2}}nezidingo zokuqina kwezinga lokushisa eliphansi. Ukukhiqiza kuqala ngensimbi ehlanzekile,{4}}yokusanhlamvu ukuze wenze isiqiniseko sokuthi impahla ingamunca umthelela kumazinga okushisa angaphansi kwezinga-qhwa. Ukwakhiwa nosayizi kuyalawulwa ukuze ipayipi igcine i-OD enembile, udonga nokuqondile, okubalulekile uma imigqa yenziwe ngaphambili futhi ishiselwe{6}. Ikhwalithi yangaphakathi yangaphakathi iphinde igadwe ukuze kugcinwe izici zokugeleza ezinhle kuwoyela, igesi noma imidiya yezinsiza.

Ngemva kokwakhiwa, amapayipi afakwa emjikelezweni wokwelapha olawulwayo-wokwelapha. Lesi sinyathelo asikona nje ukukhulula ingcindezi - ngokuyinhloko siwukubuyisela i-ductility kanye nokukhipha i-microstructure ukuze amanani omthelela we-Charpy -ku-45℃(noma izinga lokushisa elishiwo ngohlelo) kuhlangatshezwane nalo. Ukujwayela okufanele noma ukushisisa kulungisa okusanhlamvu, kuthuthukisa ukuqina kwenotshi, futhi kunikeza ipayipi ukumelana kangcono nomthelela ongazelelwe noma ukushintshashintsha kwengcindezi ezimeni zesevisi ebandayo.

-Ukubekezelela okukhethekile kwephrojekthi kanye nezimfuneko ze-NDE zingafakwa ezinhlelweni zokusebenza ezibalulekile.

I-ASTM A333 yeBanga lesi-6 inikeza ukushisela okuzinzile kokuhlangana kwe-modular nokwakhiwa kwenkundla.

Kodwa-ke, izakhiwo zezoni ethintekile{0}zone (HAZ) kufanele zigcinwe ngokucophelela ukuze kuqinisekiswe ukusebenza{1}}kwezinga lokushisa eliphansi:

• Ukuhambisana kwenqubo yokushiselange-SMAW, GTAW, kanye ne-GMAW yakho kokubili amalunga esitolo nawenkundla
• I-WPS/PQR efanelekayookudingekayo ukuze kuqinisekiswe ukuqina komthelela ngemuva kokushisela emisebenzini ye-cryogenic
• Ukulawula okokufaka ukushisa okuqinileukuvimbela ukuhwalala okusanhlamvu kanye nokulahlekelwa ukuqina kwenotshi ku-HAZ
• I-PWHT isekelwe esimweni sesevisikanye nezidingo zekhodi yokuklama ukuthuthukisa ukufana kwe-weld joint
• Ukuhlolwa komthungo we-Weld (UT/RT)kunconyelwe i-LNG nezinhlelo zokusebenza ze-arctic ezinomphumela omkhulu wokwehluleka

Isicelo esifanelekile senqubo yokushisela siqinisekisa ukuthi ipayipi elifakiwe ligcina ukumelana nokuphuka kanye nokusebenza okuqinile-kusebenza okuqinile ngaphansi kwemijikelezo yokuqala ebandayo.

Ukuhlola okwengeziwe (PMI / UT 100% /{1}}ufakazi wenkampani yesithathu) kuyatholakala kumayunithi abalulekile.

• Izitshalo zokubuyisela kabusha i-LNG kanye nezitshalo zokukhipha uketshezi
• Amapayipi e-Cryogenic kanye nesiqandisi
• Ukudluliswa kukawoyela negesi e-Arctic
• Imikhumbi{0}}yengcindezi yezinga lokushisa ephansi namamojuli
• Ingqalasizinda yesimo sezulu esingasogwini kanye nasogwini{0}ezibandayo
• Idizayinelwe ukugwema izingozi zokwehluleka okuqinile ekwehleni okukhulu kwezinga lokushisa.

I-Octal Pipe isekela ukusebenza kwepayipi le-cryogenic ngezinqubo zokushisela ezifanelekayo, amarekhodi okuhlolwa komthelela aqinisekisiwe, kanye nokulandeleka kwezinto ezibonakalayo ukusuka emshinini kuya ekufakweni.

Ukuthobela{0}ukunikezwa okugxilisiwe, ukuhlola okwenziwe ngendlela oyifisayo, nokulethwa okuthembekile kwenza i-ASTM A333 Grade 6 kusukela ku-Octal Pipe ibe ukukhetha okuqinisekisiwe kwe-LNG kanye{3}}nezindawo zesevisi yezinga lokushisa eliphansi.

FAQ

 

 

Q1: Lisetshenziselwa ini ipayipi le-ASTM A333 Grade 6?

A1:{1}}Amapayipi esevisi yengcindezi yezinga lokushisa ephansi lapho kudingeka khona ukuqina komthelela.

Q2: Yiliphi izinga lokushisa lokuhlola umthelela elivame ukucaciswa ku-A333 Grade 6?

Q3: Uyini umehluko phakathi kwe-ASTM A333 Grade 6 ne-ASTM A106 Grade B?

I-A3: I-A333 Ibanga lesi-6 ifanelekela-ukuqina kwezinga lokushisa eliphansi (umthelela uhloliwe), kuyilapho i-A106 Ibanga B ikakhulukazi isevisi-yezinga lokushisa eliphezulu.

Q4: Ingabe kufanele ngikhethe ipayipi elingenamthungo noma le-ERW elishiselwe i-A333 Grade 6?

I-A4: Khetha ngokusekelwe kubukhulu be-NPS/udonga, ububanzi obudingekayo be-NDE, kanye nenqubo yokwamukela iphrojekthi.
