I-LSAW vs HSAW (SSAW) Amapayipi: Umehluko Obalulekile

Ipayipi le-SSAW liyiphatha kanjani ingcindezi?

Umthamo wengcindezi uwukuthiidizayini{{0}esekelwe-kuya ngokuthiI-OD, ukujiya kodonga, ibanga lensimbi (i-SMYS/ingcindezi evumelekile), isici sokuklama, isibonelelo sokugqwala, nezinga lokushisa lokusebenzangaphansi kwekhodi/isicaciso esisebenzayo. Kupayipi lomugqa we-SSAW/HSAW, ubuqotho bengcindezi buvikelwa ngokulawulaumthungo we-helical: abathengi ngokuvamile bayacacisangokugcwele-ubude be-weld seam NDT (UT/RT ngokwephrojekthi ye-ITP)futhi zidinga ukuhlolwa kwe-hydrostatic uma kusebenza, ngakho ukwamukelwa kusekelwe ekubhalweni kobuqotho bomthungo kanye nobufakazi bokuhlola. Umthetho osebenzayo ekuthengeni yilokhu: uma isevisi ingaphezulu-kubungozi (ingcindezi ephezulu, isevisi emuncu, noma izimfuneko zomnikazi eziqinile), qinisa i-odagrade/WT ukukhethwa kanye nomthungo NDT ububanziesikhundleni sokuthembela ezimangalweni ezijwayelekile "zokusebenza kwengcindezi".

Kumaphrojekthi we-SSAW/HSAW, "ukudlula/ukwehluleka" akuvamile mayelana nezimangalo zamandla ajwayelekile-kufika kokuthiisiyalo sokwamukela umthungo. Abathengi ngokuvamile bakhiyela ezintweni ezintathu ezibalulekile, futhi yilapho kanye i-Octal Pipe ibeka khona ukulawula kanye nobufakazi.

• Ukungaguquguquki komthungo (ukwakha → ukuzinza kwe-weld):Ikhwalithi ye-helical seam iqala ngaphambi kokushisela. Uma ukwakheka kwe-spiral kungazinzile, uzokubona kamuva njengeukuzulazula komthungo, i-ovality drift, nephrofayili yobuhlalu engalingani, okube sekucupha i-NDT eyengeziwe kanye nezingxoxo zokulungisa. I-Octal Pipe ilawula ukwakheka kwesethi{1}}futhi igcina amapharamitha wokushisela ngaphakathi kwefasitela elichaziwe ukuze umthungo uhlale ufana ukusuka epayipini lokuqala ukuya kowokugcina endaweni.
• Ububanzi be-NDT obungubufakazi bokuhlola-(hhayi ukuthi "senze ukuhlola"):Okubuzwa ngabathengi ukuthi:Ingabe i-helical seam ihlolwe ubude obugcwele? Iyiphi indlela, futhi yisiphi isisekelo sokwamukela?I-Octal Pipe iqondanaUkufakwa kwe-UT/RTkanye nomthetho wesimo (ukwamukela/{0}}ukuhlola/wenqaba) kuzinga elibusayo kanye nephrojekthi ye-ITP, futhi inikeza ubufakazi bokuhlola njengengxenye yephakethe lokukhishwa{1}}yilokhu okuvimbela izindawo zokubamba kanye{2}}nezihibe zokuhlola.
• Ukulandelelwa kwedokhumenti okusinda eqinisweni lesayithi:Ukulahlwa okuningi kwenzeka ngemva kokulethwa lapho amapayipi asesiteji futhi iklayenti lingakwazi ukuhlanganisaukushisa/ikhoyili → ukumaka ipayipi → imibiko ye-NDT/hydro → MTC. I-Octal Pipe iletha iphekhi elilandelekayo (EN10204 3.1; 3.2 ngesicelo) elinemephu yenkatho, ukuze i-QA ikhulule okubalulekile ngaphandle kokujaha izixhumanisi ezingekho.

Lapho abathengi bebuza iumehluko phakathi kwamapayipi e-LSAW ne-HSAW, umbuzo wangempela awukona nje kuphela ukuthi "i-plate vs coil" - ukuthi iluphi uhlobo lomthungo olunciphisa ukugunyazwa, ubungozi benkundla, kanye nokuchayeka kweshejuli ngaphansi kokucaciswa kwephrojekthi.

Umehluko omkhulu othinta ukugunyazwa nokusebenza kwesayithi

Ingabe izindleko zepayipi le-SSAW-ziyasebenza?

Kumadayamitha amakhulu, i-SSAW ivamise ukubiza-ukusebenza kahle ngoba isekelo{1}}elisekelwe ku-spiral formingukukhiqizwa okuqhubekayo kanye nokusebenza okuzinzile, okuyinto evame ukuthuthukisa i-izindleko-isikhathi sokuhola ibhalansikumaphakheji{{0}ama-OD amakhulu. Inani langempela livamise ukungenaisamba sezindleko ezifakiwe, hhayi ukulondoloza okungu-% okufunwayo: lapho okulethwayoihlanganiswe ngenkatho/usayizi ukuze ifane nendawo yokusebenza, osonkontileka banciphisa isikhathi sokuhlunga, ukunyakaza kwe-crane, kanye nokuma "usayizi ongekho".

Kumathenda amaningi, i-SSAW iba "izindleko-esebenza kahle" uma yehlisa ukushayisana okuphelele kwephrojekthi{1}}iziphazamiso ezimbalwa zokuhlela, ukukhishwa kwe-QA okushelelayo, nokusebenza kabusha okuncane kwesayithi{2}}kunokuthembela enanini eliphansi leyunithi kuphela.

Ipayipi le-SSAW (HSAW) livame ukucaciswa lapho izinselelo zesizinda somsebenzi sezimayelanaukuphatha, ukumboza ubuqotho, ukulinganisa{0}isivinini, kanye nokukhulula amaphepha, hhayi nje "amandla epayipi." KusukaIpayipi le-OctalUkubuka kokuthengwa kwempahla, iphakethe elilungile le-SSAW yilonaisinda ezimeni zesayithi ngamaphoyinti ambalwa wokubamba kanye nokusebenza kabusha okuncane, esekelwe ubufakazi bokuhlola obucwaningekayo.

• Ukufinyelela okunomkhawulo (imizila yentaba / UMROW omncane / ukuphakama okulinganiselwe):
• Inkinga yendawo yomsebenzi ayizishiseli ngokwayo-yiyoisikhathi sokuqondanisa: umhlabathi ongalingani kanye nezinyathelo ezimfushane zokuphakamisa zikhulisa izindaba ezifanai-ovality, ukukhukhuleka okuqondile, nesimo sokuphela esingaguquki, okwenza ukulingana{0}}hamba kancane futhi kukhulise ukulungiswa okuphoqelekile. I-Octal Pipe ngokuvamile isekela lawa masayithi ngokukhiyaizilawuli ze-dimensional (OD/ovality/straightness) kanye ne-end prep (PE/BE)ngaphambili, nokuthunyelwa ngokuhlonza inqwaba ecacile ukuze abasebenzi bangachithi isikhathi sokuhlunga osayizi ngaphambili komsebenzi.
