ASTM A333 Gulu 6 Chitoliro

ASTM A333 Giredi 6 imakwirira mapaipi achitsulo osasunthika komanso owotcherera omwe amagwiritsidwa ntchito potentha kwambiri mpaka -50 digiri F (-46 digiri).

Chitsulocho chimapangidwa kuti chikhale cholimba pansi pazigawo za subzero, kuthandizira kutetezedwa kotetezedwa ndi kukhazikika kwadongosolo pamachitidwe a cryogenic monga ma terminals a LNG, malo opangira gasi, ndi zida zamapaipi a Arctic.

Makhalidwe ofunikira:

• Kulimbana ndi Crack pansi pa kutentha kwapakati
• Mphamvu yokhazikika panthawi yozizira yoyambira
• Wodalirika weldability kwa unsembe kumunda
• Imagwirizana ndi-zotentha za ASME zotsika

Kutsika kwa sulfure ndi phosphorous kumawonjezera kulimba kwa notch pa kutentha kochepa.

Charpy V-Kuyesa kwa Notch kumatsimikizira kusweka kwa LNG ndi ntchito zapamtunda.

Mapaipi a ASTM A333 Giredi 6 amapangidwa mopanda msoko kapena ngati mipope yowotcherera, koma m'njira zonsezi amapangidwa kuti akwaniritse{2}}zofunika kulimba kwa kutentha. Kupanga kumayamba ndi zitsulo zoyera, zoyera{4}}zotsimikizira kuti zinthuzo zitha kuyamwa kutentha kochepera paziro. Mapangidwe ndi makulidwe amayendetsedwa kuti chitoliro chisunge OD molondola, khoma ndi kuwongoka, zomwe ndizofunikira ngati mizere yapangidwa kale komanso yomangika-. Ubwino wamkati wamkati umawunikidwanso kuti ukhalebe ndi mawonekedwe abwino amafuta, gasi kapena media media.

Akapanga, mapaipi amalowetsedwa m'nyengo yowotchera-yowongolera. Sitepe iyi sikungochepetsa nkhawa - ndikubwezeretsa ductility komanso kutulutsa mawonekedwe ang'onoang'ono kuti Charpy amakhudzidwa ndi -madigiri 45 (kapena kutentha komwe kwafotokozedwa) kukwaniritsidwe. Kutentha koyenera kapena kutentha kumayenga njere, kumapangitsa kuti chitoliro chikhale cholimba, komanso chimapangitsa kuti chitolirocho chisasunthike mwadzidzidzi kapena kusinthasintha kwamphamvu m'malo ozizira.

Pulojekiti-zololera mwapadera ndi zofunikira za NDE zitha kuphatikizidwa pazofunikira kwambiri.

ASTM A333 Giredi 6 imapereka kuwotcherera kokhazikika pakumangirira modula komanso kumanga minda.

Komabe, kutentha-zone yokhudzidwa (HAZ) iyenera kusamalidwa bwino kuti{1}}kuwonetseke kuti kutentha kumachepa:

• Kuwotcherera ndondomeko yogwirizanandi SMAW, GTAW, ndi GMAW pa malo ogulitsa ndi kumunda
• Woyenerera WPS/PQRzofunika kutsimikizira kulimba kwamphamvu pambuyo kuwotcherera mu ntchito za cryogenic
• Kuwongolera kolowera kutentha kwambirikuti tipewe kufota kwa tirigu ndi kutayika kwa notch kulimba mu HAZ
• PWHT kutengera momwe ntchito ikuyenderandi zofunikira pakupanga ma code kuti apititse patsogolo mgwirizano wa weld
• Kuyang'ana kwa Weld Seam (UT / RT)akulimbikitsidwa LNG ndi Arctic ntchito ndi zotsatira mkulu kulephera

Kugwiritsa ntchito njira zowotcherera moyenera kumatsimikizira kuti payipi yoyikidwiratuyo imasungabe kusweka ndi kudontha-kumagwira ntchito molimba poyambira kuziziritsa.

Mayeso owonjezera (PMI / UT 100% / wachitatu-mboni wa gulu) amapezeka pamayunitsi ovuta.

• LNG regasification ndi liquefaction zomera
• Mapaipi a Cryogenic ndi refrigeration
• Kutumiza kwamafuta ndi gasi ku Arctic
• Zotengera zotsika-zotsika komanso ma module
• Zanyengo zakunyanja ndi kunyanja-zozizira kwambiri
• Zapangidwa kuti zipewe ngozi zolephera pang'onopang'ono pakutsika kwambiri kwa kutentha.

Octal Pipe imathandizira magwiridwe antchito a mapaipi a cryogenic ndi njira zowotcherera zoyenerera, zolemba zoyeserera zotsimikizika, komanso kutsatiridwa kwazinthu kuchokera pamphero kupita kuyika.

Kutsatira-kukhazikika, kuyang'anira mwamakonda, ndi kutumiza kodalirika kumapangitsa ASTM A333 Giredi 6 kuchokera ku Octal Pipe kukhala chisankho chotsimikizika cha LNG ndi malo ochepera-magawo achitetezo.

FAQ

 

 

Q1: Kodi chitoliro cha ASTM A333 Grade 6 chimagwiritsidwa ntchito chiyani?

A1: Kutsika{1}}mapaipi amtundu wa kutentha komwe kumafunika kulimba.

Q2: Ndi kutentha kotani komwe kumayesedwa pafupipafupi kwa A333 Grade 6?

A2: Nthawi zambiri −45 digiri (−50 digiri F), pokhapokha ngati polojekitiyi ikufotokozera kutentha kosiyana.

Q3: Kodi pali kusiyana kotani pakati pa ASTM A333 Grade 6 ndi ASTM A106 Grade B?

A3: A333 Giredi 6 ndiyoyenerera kutsika-kulimba kwa kutentha (kuyesedwa kwachiyembekezo), pomwe A106 Giredi B ndiyomwe imagwira ntchito-yapamwamba kwambiri.

Q4: Kodi ndisankhe chitoliro chopanda msoko kapena ERW welded A333 Grade 6?

A4: Sankhani kutengera makulidwe a NPS/khoma, kuchuluka kwa NDE kofunikira, ndi njira zovomerezera polojekiti.
