Ithelo le-ASME A334 lihlanganisa amashubhu ensimbi ekhabhoni ane-seam kanye nama-welded ahloselwe ukusetshenziswa emazingeni okushisa aphansi, okwenza kube yindinga eyinhloko yezimboni ezisebenza ezindaweni ezinamazinga okushisa aphansi kakhulu noma angaphansi kweqanda. Leli zinga liyaziwa kabanzi emkhakheni kawoyela negesi, ukucutshungulwa kwamakhemikhali, kanye nemikhakha yokukhiqiza amandla ngoba liqinisekisa ukuthi izinto zokwakha zigcina ukuqina nokunwebeka noma ngabe amazinga okushisa ehla kakhulu ngaphansi kweqanda. Onjiniyela kanye nochwepheshe bokuthenga bathembela ku-ASME A334 seamless steel tube ezinhlelweni ezibucayi lapho ukuphuka nokuqhekeka kungaholela ezingozini ezinkulu, ngakho ukuqonda izidingo zalo kubalulekile kunoma yimuphi umsebenzi obandakanya ukusebenza emazingeni okushisa aphansi. Ithelo linikeza imininingwane ngamazinga amaningi, kanti i-Gr.1 ne-Gr.6 yizona ezikhethwa kakhulu ngenxa yokumelana nokushayeka okuhle kanye nokusebenza kwemishini okuthembekile ezimweni ezibandayo kakhulu. Ngokulandela imikhawulo eqinile ekwakhekeni kwamakhemikhali kanye nokudinga ukuhlolwa okungaphephile kwe-Charpy V-notch impact, i-ASME A334 iqinisekisa ukuthi ishubhu ngalinye lingamelana nokucindezeleka kokushisa kanye nemithwalo yokucindezela evamile ezinhlelweni zamapayipi asebenza emazingeni okushisa aphansi kakhulu. Ezinkampanini ezinjenge-Wuxi Hengzhihui Metal Materials Co., Ltd, ukugcina nokuhlinzeka nge-ASME A334 seamless steel tube kuyingxenye eyinhloko yokuzibophezela kwabo ekulethweni kwemikhiqizo eqinisekisiwe yokuphepha kumakhasimende omhlaba wonke afuna ikhwalithi engenakuphikiswa.

I-ASME A334 ihlanganisa amabanga amaningana, kodwa i-Gr.1 ne-Gr.6 yiwona acaciswa kakhulu ngoba anikeza ibhalansi ekahle yamandla, ukushiswa kalula, nokuqina ekushiseni okuphansi. I-Grade 1 inamandla amancane okukhiqiza angu-205 MPa nobubanzi bamandla okudonsa obungu-345–455 MPa, kuyilapho i-Grade 6 inikeza amandla aphezulu ngamandla amancane okukhiqiza angu-240 MPa namandla okudonsa angu-415–585 MPa, okwenza ibanga ngalinye lifaneleke ezidingweni ezahlukene zokucindezela nezinga lokushisa. Ukwakheka kwamakhemikhali kwalawa mabanga kulawulwa ngokuqinile: izinga lekhabhoni ligcinwa lingaphansi kuka-0.30% ku-Gr.1 nangu-0.30% ku-Gr.6, kanti i-manganese, i-phosphorus, i-sulfur, ne-silicon zikhawulelwa ukuze kuqinisekiswe ukusebenza okungaguquki kokushaya emazingeni okushisa aphansi afinyelela ku-–50 °F (–45 °C). Lokhu kulinganisela ngokucophelela kwezakhi kuthinta ngqo ikhono lepayipi lokumelana nokuphuka okunzima, okuyindlela eyinhloko yokwehluleka ekusetshenzisweni emazingeni okushisa aphansi, ngakho-ke yonke insimbi eshiswayo kumele idlule isitifiketi esiqinile sokuhlolwa kwezimboni. Ngaphezu kwamabanga ayisisekelo, izinga lokushisa lifaka nezidingo ezingeziwe zokuhlolwa okuthuthukisiwe kwe-NDT, ukuhlolwa kwe-hydrostatic, nokuqinisekiswa kokwelashwa ngokushisa, okunikeza abathengi izendlalelo eziningi zokuqinisekiswa kwekhwalithi. Noma ngabe iphrojekthi idinga ipayipi lensimbi yekhabhoni enezinga lokushisa eliphansi embonini yokucubungula igesi noma ipayipi lensimbi elingena-mthungo elisebenzela amazinga okushisa aphansi endaweni ye-liquefied natural gas, i-ASME A334 inikeza ukuqiniseka kobunjiniyela okudingekayo ukuze kwakhiwe amasistimu aphephile, ahlala isikhathi eside.

Okushi okwehlukanisa ngempela i-ASME A334 kwezinye izindinganiso zamapayipi ensimbi yekhabhoni imfuneko yokuhlolwa komthelela (impact testing) okuyimpoqo, okuqinisekisa ukuthi impahla imunca amandla anele ukugwema ukuphuka okuzumayo ezingeni lokushisa eliphansi lokuklama. Ku-Gr.1 ne-Gr.6, inani lokuhlolwa kwe-Charpy V-notch elingosayizi ogcwele kumele lihlangabezane okungenani ne-18 J (13 ft·lbf) njengesilinganiso uma kuhlolwa ezingeni lokushisa eliphansi elishiwo, kuqinisekiswa ukuziphatha okunwebekayo ngisho nangaphansi komthwalo wokushaqeka. Lokhu kusebenza kubalulekile ezinhlelweni zamapayipi okumele zihlale zisebenza ebusika base-Arctic noma emifudlaneni yezinqubo ezinamazinga okushisa aphansi kakhulu, lapho izinsimbi ezijwayelekile zingaba buthakathaka ngendlela eyingozi. Inhlanganisela yokwakheka kwamakhemikhali okulawulwayo, ukwakheka kwezinhlayiya ezicolekile, nokwelashwa ngokushisa okufanele kukhiqiza ishubhu eligcina ukunwebeka nokuncipha kwendawo ngaphakathi kwemikhawulo eyamukelekile, livumela ukugoba endle nokushisela ngaphandle kokudela ukuphepha. Onjiniyela bavame ukuqhathanisa i-ASME A334 nezinye izindinganiso ezifana ne-API 5L noma i-ASTM A106 lapho beklama izinhlelo ezihlanganisa izinto ezihlukene, kodwa ezingxenyeni zamazinga okushisa aphansi, i-A334 ihlala iyisinqumo esiyinhloko. Kumthengisi onjenge-Wuxi Hengzhihui, ukuhlinzeka ngezitifiketi zokusebenza (mill certificates) ezibhala ngokucacile le miphumela yokuhlolwa komthelela kuyingxenye evamile yesevisi yabo yokuthumela kwamanye amazwe, okunikeza abathengi ukulandeleka okugcwele kusukela ekuncibilikeni kuze kube ishubhu eliqediwe.

Ishubhu lensimbi elingena-mthungo le-ASME A334 liyinto esemqoka emapayipini okucubungula, emashubhini okushintshanisa ukushisa, nasemigqeni yamathuluzi asebenza emazingeni okushisa angaphansi kuka-–20 °F, futhi ukusetshenziswa kwalo kuvame kakhulu ezitshalweni zokwenza igesi yemvelo ibe uketshezi, ezitshalweni zokuhlukanisa i-ethylene, nasezinhlelweni zokupholisa nge-ammonia. Emkhakheni kawoyela negesi, lawa mashubhu afakwa kumanethiwekhi okuqoqa igesi, ezindaweni zokuhlukanisa, nasezindaweni zokugcina i-LNG lapho ubungozi bokuphuka okuncipha kancane kufanele bancishiswe ukuze kuvikelwe abasebenzi nezimpahla. Izitshalo zamakhemikhali zithembela ku-A334 Gr.1 no-Gr.6 emapayipini aphatha uketshezi olubandayo kakhulu njenge-nitrogen ewuketshezi, i-oxygen ewuketshezi, nama-hydrocarbon awuketshezi, lapho nokuvuza okuncane kungakhula kube isigameko esikhulu sokuphepha. Ukugcizelela kwezinga lokuvikela ukuphuka kusho ukuthi ama-weld enziwe ngezinto zokufaka ezihambisanayo nawo agcina izakhiwo zokumelana nomthelela, okuvumela abakhi ukuthi bakhe izinhlelo zamapayipi eziyinkimbinkimbi eziphumelela ekuhlolweni okuqinile kwesayithi. Ngaphandle kokukhiqizwa kwamandla okusemqoka, lawa mashubhu asetshenziswa nasezinhlelweni ezisizayo zeziteshi zamandla enuzi nasezinqubweni zemithi ezidinga amazinga okushisa aphansi kakhulu, okubonisa ukusebenza ngokuguquguquka kwalokhu kucaciswa. Ngenxa yokuthi i-Wuxi Hengzhihui igcina inqwaba enkulu yamashubhu ensimbi angena-mthungo e-ASME A334 ngobubanzi obuhlukahlukene nangobukhulu bodonga, bakwazi ukusekela kokubili ukumiswa kokulungisa okuhleliwe kanye nokulethwa kwemisebenzi ngokushesha kumakhasimende kulezi zimboni ezidingayo.

Umugqa ojwayelekile we-LNG liquefaction usebenzisa amamitha angamakhulu we-A334 Gr.6 piping ukuthutha i-methane ku-–162 °C, futhi ingxenye ngayinye kumele iphaswe ukuhlolwa kwe-radiographic okungu-100% kanye nokuhlolwa kwemiphumela okuphoqelekile. Emkhakheni wamakhemikhali, izitshalo ze-ethylene zisebenza ku-–104 °C kumakhabethe azo abandayo, lapho amashubhu e-A334 Gr.1 esebenza njengamapayipi okucubungula kanye namashubhu okushintshanisa ukushisa okumele abekezelele ukushintsha kokushisa nokushintsha kwengcindezi. Izindawo zokuhluza ezindaweni ezibandayo ziya ngokuya zicacisa amashubhu e-A334 seamless emigqeni yamalangabi kanye nezinhlelo zokwehlisa umfutho ukuvimbela ukuphuka ngenxa yokubanda ngesikhathi sokukhishwa okuphuthumayo. Lezi zinhlelo zidinga hhayi nje izinga elifanele kodwa futhi ukulinganisa okunembile kanye nokupheliswa kwendawo, yingakho abathengi bevame ukuthenga kubaphakeli abanekhono elikhethekile lokuphelisa okubandayo. Ikhono lika-Wuxi Hengzhihui lokwenza ngendlela ubude kanye nokulungiselela iziphetho lisho ukuthi abakhi bathola amashubhu alungele ukufakwa, okunciphisa umsebenzi wokuphinda wenziwe endaweni futhi kufinyeze izikhathi zokuqedwa kwephrojekthi. Ngokukhetha uzakwethu onobufakazi bokuthumela emazweni angaphandle, izinkampani ziqinisekisa ukuthi ipayipi labo lensimbi yekhabhoni elisezingeni eliphansi lihlangabezana nazo zonke izimfuneko zephrojekthi kusukela ngosuku lokuqala.

Ishubhu lensimbi elingena-umthungo le-ASME A334 lingakhiqizwa ngezinqubo zombili ezishisayo (hot-finished) nezipholile (cold-finished), nakuba ukudonsa okubandayo (cold drawing) kuvame ukukhethwa ezinhlelweni ezidinga ubukhulu obunembile (dimensional tolerances) nendawo ebushelelezi. Ukulandelana kokukhiqiza kuqala nge-billet eyindilinga eqinile efudunyezwa bese igqojozwa ukuze kwakheke igobolondo elingaphakathi, elide iselulwa ngochungechunge lwemisebenzi yokugingqika noma yokudonsa kuze kutholakale ububanzi nokujiya kodonga okufunwayo. Emashubhu aphelile abandayo (cold-finished), into idonswa ibanda noma igingqikwe ibanda, ilandelwe ukwelashwa kokugcina ngokushisa — ngokuvamile i-normalizing, i-normalizing nokuthambisa (tempering), noma ukukhulula ingcindezi (stress relieving) — ukuze kubuyiselwe ubumnene (ductility) nokuqinisekisa ukwakheka okufanayo kwezinhlamvu (grain structure). Lesi sinyathelo sokwelashwa ngokushisa sibalulekile ekutholeni izakhiwo zomthelela wokushisa okuphansi ezidingwa yizinga, ngoba sicwenga ukwakheka kwe-pearlite-ferrite microstructure futhi sikhulule izinsalela zengcindezi ezivela emisebenzini yokubumba. Ngemva kokwelashwa ngokushisa, amashubhu ayolulwa, asikwe abe ubude obufanele, futhi ahlolwe ngezindlela ezingonakalisi (non-destructive testing) njenge-eddy current, i-ultrasonic, noma ukuhlola nge-magnetic particle ukuze kutholakale noma yikuphi ukuphazamiseka okungaphezulu noma kwangaphakathi. I-Wuxi Hengzhihui isebenza nezigayo eziqinisekisiwe nge-ISO ezilandela lezi zinqubo ngqo, futhi bangahlinzeka ngemibhalo enemininingwane yenqubo ukuze basize abathengi baqinisekise ukuthobela ikhodi ye-ASME ngesikhathi sokuhlola ikhwalithi kwabo.

Ukujwayela, okubandakanya ukushisisa insimbi ngaphezu kwezinga layo eliphezulu lokushisa elibizwa nge-upper critical temperature bese kulandelwa ukupholisa emoyeni, kukhiqiza ukwakheka okucwebezelayo okufanayo okwandisa ukuqina (toughness) ku-A334 Gr.1 naku-Gr.6. Abanye abakhiqizi bangase basebenzise umjikelezo wokucisha nokupholisa (quench-and-temper) we-Grade 6 ukuze bathole amazinga aphezulu okuqina kuyilapho besaqhubeka nokuhlangabezana nezidingo zomthelela (impact requirements), kodwa izinga lokushisa livumela lokhu kuphela uma umkhiqizi ebonisa ukuthi zonke izinhloso zezakhiwo ziyahlangabezana ngokungaguquki. Ihhavini yokwelapha ngokushisa kumele ilinganiswe ukuze igcine ukushisa okufanayo kuyo yonke indawo, ukuze wonke amashubhu esigabeni athole umjikelezo ofanayo wokushisa, kugwenywe izindawo ezithambile noma izindawo eziqinile ezingaphazamisa ukusebenza. Ngemva kokwelashwa ngokushisa, izingcezu zokuhlola ziyanqunywa kusukela kusigaba ngasinye sokwelashwa ngokushisa bese zihlolwa ngokuhlolwa kwe-Charpy impact, ukuhlolwa kokudonsa (tensile testing), nokulinganiswa kokuqina (hardness measurement) ukuze kuqinisekiswe ukuthi impahla iyahlangabezana nencazelo. Emashubhini aqedwe ngokubanda (cold-finished), ukukhulula ingcindezi (stress relieving) ezingeni eliphansi lokushisa kungase kusetshenziswe esikhundleni sokujwayela okugcwele, inqobo nje uma izidingo zomthelela zisagculiswa, kodwa abonjiniyela abaningi bakhetha umkhiqizo ojwayelwe ngokugcwele uma usetshenziselwa izimo ezibandayo ezibalulekile. Ngokulawula zonke izinyathelo kusukela ku-billet kuya kushubhu eliqediwe, abahlinzeki abanjengo-Wuxi Hengzhihui bahlinzeka nge-ASME A334 seamless steel tube esebenza ngokuthembekile emkhakheni.

Iqiniso lokulawulwa kwekhwalithi le-ASME A334 seamless steel tube lidlula nje ukubhekwa okulula ngamehlo, lidinga uchungechunge lwezivivinyo eziqinisekisa ukuqina kwemishini, ukungavuzi, kanye nokungabi namaphutha ayingozi. Ithubhu ngalinye kumele lidlule ekuhlolweni kwe-hydrostatic ngomfutho obalwe ukuze kucindezelwe udonga lube yipesenti elithile lamandla amancane okuguquguquka, kuqinisekiswa ukuthi ipayipi lingakwazi ukumelana nomfutho wokusebenza okuhlosiwe ngaphandle kokuvuza. Ngaphezu kokuhlolwa kwe-hydrostatic, izindlela zokuhlola ezingonakalisi njengokuhlola nge-ultrasonic kanye nokuhlola ngogesi zisetshenziswa ukuthola imifantu emide noma enqamulelayo engase ibe yizinto ezikhulisa ingcindezi ekusetshenzisweni emazingeni okushisa aphansi. Abakhiqizi kumele futhi benze ukuhlolwa kokucindezela, ukuhlolwa kwe-flange, kanye nokuhlolwa kokuqina kumasampula amele ibhajethi ngalinye lokukhiqiza, futhi yonke imiphumela ibhalwe phansi esitifiketini sokuhlolwa kwesikhungo esihambisana nokuthunyelwa. Izikhungo zokuhlola ezizimele ezifana ne-Bureau Veritas, i-Lloyd's, noma i-DNV zivame ukuqashwa ukuze zibone ukuhlolwa futhi zibuyekeze imibhalo, zinikeze ukwethemba okwengeziwe kubathengi bamazwe ngamazwe. I-Wuxi Hengzhihui inesitifiketi se-ISO 9001 futhi igcina uhlelo lokulawula ikhwalithi olunikezelwe oluhlanganisa ukuqinisekiswa kwezinto ezingenayo, ukuhlolwa phakathi nenqubo, kanye nokukhishwa komkhiqizo wokugcina, njengoba kuboniswe ekhasini labo Lezitifiketi. Ikhono labo lokuhlinzeka ngamathubhu anokulandeleka okugcwele kanye nemibiko yokuhlolwa ngesiNgisi, isiShayina, noma ezinye izilimi kwenza kube lula ukusula empahleni nokwamukelwa endaweni yabathengi bomhlaba wonke.

Ukuhlolwa kwe-Ultrasonic kusebenzisa amaza omsindo anemfrikhwensi ephezulu ukuskena wonke udonga lweshubhu, futhi kusebenza kahle kakhulu ekutholeni ama-laminations, ama-inclusions, kanye nemifantu engase yande ngaphansi kwengcindezi yokushisa okuphansi. Ukuhlolwa kukagesi, okuhlanganisa izindlela ze-eddy current kanye ne-flux leakage, kuyindlela ehambisanayo ehlonza ukukhubazeka okugqamayo ebusweni ngesivinini esikhulu, okwenza kufanelekele ukuhlolwa okungu-100% emgqeni ngesikhathi sokukhiqiza. Emsebenzini obalulekile, abanye abathengi bacacisa ukuthi kokubili ukuhlolwa kwe-ultrasonic nokukagesi kwenziwe, nakuba izinga lokuhlola lifuna indlela eyodwa ye-NDT ngaphandle uma kuvunyelwene ngenye indlela. Ukuhlolwa kwe-Charpy impact akusiyo indlela engalimazi, ngoba kubhubhisa isampula lokuhlola, kodwa kuyimpoqo ngaphansi kwe-ASME A334 ngoba kukala ngokuqondile amandla okwazi ukumunca amandla okushisa ngezinga lokushisa eliphansi eliklanyelwe. Ukuhlolwa nge-radiographic kungase kwengezwe ezinhlotsheni zamashubhu ahlanganisiwe noma emifuleni yokujikeleza eyenziwa ngesikhathi sokufaka, nakuba amashubhu angenamthungo ngokuvamile edinga izithombe ezimbalwa ze-radiographic ngenxa yokungabi bikho komthungo omude. Ngokunikeza izinketho eziningi ze-NDT njengengxenye yokunikezwa kwabo okujwayelekile, i-Wuxi Hengzhihui isiza amakhasimende ukuthi ahlangabezane nezidingo zawo zokulawula ikhwalithi ngaphandle kwesidingo sokuhlolwa kabusha okubizayo kwenkampani yangaphandle.
