I-ASTM A333 yeBanga lesi-6 uMbhobho

I-ASTM A333 yeBanga lesi-6 igquma imibhobho yentsimbi engenamthungo nedityanisiweyo esetyenziswa kumaqondo obushushu asezantsi ukuya kuthi ga kwi -50℃F (-46 degree).

Intsimbi yenzelwe ukugcina ukuqina phantsi kweemeko ezingaphantsi, ukuxhasa ukunyanzeliswa koxinzelelo olukhuselekileyo kunye nokuzinza kwesakhiwo kwiinkqubo ezifunwayo ze-cryogenic ezifana ne-LNG terminals, i-gas processing plant, kunye neziseko zemibhobho ye-arctic.

Iimpawu eziphambili zokusebenza:

• Ukumelana nokuqhekeka phantsi kwe-thermal contraction
• Amandla azinzileyo ngexesha lemijikelezo yokuqala ebandayo
• I-weldability ethembekileyo yokufakela intsimi
• Ithobela{0}}inkqubo yoxinzelelo lobushushu ephantsi ye-ASME

Isulphur ephantsi kunye ne-phosphorus ziphucula ukuqina kwenotshi kumaqondo obushushu aphantsi.

UCharpy V-Uvavanyo lweNotch luqinisekisa ukuxhathisa kokwaphuka kwe-LNG kunye nenkonzo ye-arctic.

Imibhobho ye-ASTM A333 yeBanga lesi-6 iveliswa njengemibhobho engenamthungo okanye njengemibhobho edityanisiweyo, kodwa kuzo zombini iimeko inkqubo imiselwe ukuhlangabezana{2}}neemfuno zobushushu obuphantsi. Imveliso iqala ngentsimbi ecocekileyo, ecolekileyo{4}yezinkozo ukuqinisekisa ukuba izinto zinokufunxa impembelelo kumaqondo obushushu angaphantsi kweqanda. Ukuqulunqa kunye nokulinganisa kulawulwa ukuze umbhobho ugcine iOD echanekileyo, udonga kunye nokuthe tye, okubalulekileyo xa iilayini zenziwe kwangaphambili kwaye intsimi{6} i-welded. Umgangatho wangaphakathi womphezulu uphinde ubekwe iliso ukuze kugcinwe iimpawu ezihamba kakuhle zeoli, igesi okanye imidiya eluncedo.

Emva kokwenziwa, imibhobho ifakwa kumjikelo wonyango wobushushu obulawulwayo-. Eli nyathelo alisokuthomalalisa uxinzelelo kuphela - ikakhulu kukubuyisela i-ductility kunye nokukhupha i-microstructure ukuze ixabiso lempembelelo ye-Charpy kwi- - 45℃(okanye ubushushu obuxeliweyo ngokomyalelo) buhlangabezwe. Ukufudumeza okufanelekileyo kuphucula ukutya okuziinkozo, kuphucula ukuqina kwenotshi, kwaye kunika umbhobho ukuxhathisa okungcono kwimpembelelo yequbuliso okanye ukuguquguquka koxinzelelo kwiimeko zenkonzo ebandayo.

Iprojekthi-unyamezelo olukhethekileyo kunye neemfuno zeNDE zingabandakanywa kwizicelo ezibalulekileyo.

I-ASTM A333 yeBanga lesi-6 ibonelela nge-weldability ezinzileyo kwindibano yeemodyuli kunye nokwakhiwa kwebala.

Nangona kunjalo, iipropati-ezichatshazelwe bubushushu (HAZ) kufuneka zilondolozwe ngononophelo ukuqinisekisa ukusebenza{1}} kobushushu obuphantsi:

• Ukuhambelana kwenkqubo ye-Weldingnge-SMAW, i-GTAW, kunye ne-GMAW yazo zombini ivenkile kunye neendawo zokuhlangana
• I-WPS/PQR efanelekileyoefunekayo ukuqinisekisa ukuqina kwempembelelo emva kwe-welding kwimisebenzi ye-cryogenic
• Ulawulo olungqongqo lwegalelo lobushushuukuthintela ukurhawuka kweenkozo kunye nokulahleka kokuqina kweenotshi kwi-HAZ
• I-PWHT isekelwe kwimeko yenkonzokunye neemfuno zoyilo lwekhowudi zokuphucula ukufana kwe-weld joint
• Ukuhlolwa komthungo we-Weld (UT/RT)kucetyiswa kwi-LNG kunye nezicelo ze-arctic ezineziphumo eziphezulu zokusilela

Ukusetyenziswa kwenkqubo yewelding eyiyo iqinisekisa ukuba umbhobho ofakelweyo ugcina ukuxhathisa kokuqhekeka kunye nokuvuza{0}}kukusebenza okuqinileyo phantsi komjikelo wokuqalisa obandayo ophindaphindiweyo.

Uvavanyo olongezelelweyo (PMI / UT 100% / -ingqina leqela lesithathu) luyafumaneka kwiiyunithi ezibalulekileyo.

• I-LNG regasification kunye nezityalo zokunyibilikisa
• Imibhobho ye-Cryogenic kunye nefriji
• Ioyile yeArctic kunye nokuhanjiswa kwegesi
• {0}}Iinqanawa zoxinzelelo lobushushu obuphantsi & iimodyuli
• Ngaphandle konxweme kunye nesiseko semozulu ebandayo elunxwemeni{0}}
• Yenzelwe ukunqanda imingcipheko yokungaphumeleli kwe-brittle kumaqondo obushushu asezantsi.

Umbhobho we-Octal uxhasa ukusebenza kombhobho we-cryogenic kunye neenkqubo zokuwelda ezifanelekileyo, iirekhodi eziqinisekisiweyo zovavanyo lwempembelelo, kunye nokulandeleka kwezinto ukusuka kwilitye ukuya kufakelo.

Ukuthobela{0}}ubonelelo olujolisiweyo, uhlolo olulungiselelweyo, kunye nonikezelo oluthembekileyo kwenza i-ASTM A333 iBanga lesi-6 ukusuka kwi-Octal Pipe ibe lukhetho oluqinisekisiweyo lwe-LNG kunye{3}}neendawo zenkonzo yobushushu obuphantsi.
