Line Pipe Oil API 5L Birta Line Pipe Plate
Sharaxaad Gaaban:
Birta tuubooyinka waa nooc ka mid ah saxan bir ah oo loo isticmaalo dhuumaha, badiyaa loo isticmaalo soo saarista tuubooyinka dhuumaha ee saliidda iyo gaaska dabiiciga ah, iyo sidoo kale dhuxusha iyo walxaha dhismaha.Birtu kaliya uma baahna xoog cadaadis sare leh, laakiin sidoo kale waxay u baahan tahay adkeysi heerkul hoose oo sarreeya iyo alxanka wanaagsan.
Inaad noqoto marxaladda xaqiijinta riyooyinka shaqaalaheenna!Si loo dhiso shaqaale farxad badan, midaysan oo aad u badan oo khibrad leh!Si aan u gaadhno faa'iido wadajira oo ah rajadayada, alaab-qeybiyeyaasha, bulshada iyo nafteenaba ee khadka dhuumaha shidaalkaAPI 5L Birta Xariiqda Dhuumaha, Hubi inaadan ka waaban inaad na soo wacdo haddii aad ku qanacsan tahay alaabtayada.Waxaan si adag u malaynaynaa in badeecadayada ay kaa farxin doonto.
Inaad noqoto marxaladda xaqiijinta riyooyinka shaqaalaheenna!Si loo dhiso shaqaale farxad badan, midaysan oo aad u badan oo khibrad leh!Si aan u gaarno faa'iido wadajira oo ah rajadayada, alaab-qeybiyeyaasha, bulshada iyo nafteenaAPI 5L Birta Xariiqda Dhuumaha, Waxaan ku hanweynahay in aan siino alaabadayada iyo xalalka taageere kasta oo baabuurta adduunka oo dhan ah oo leh adeegyadeena dabacsan, dhakhso badan leh iyo heerka xakamaynta tayada adag ee had iyo jeer ay ansixiyaan oo ay ammaanaan macaamiisha.
Birta dhuumaha casriga ah waa bir yar oo kaarboon ama ultra-hooseeya, taas oo ah badeecad leh farsamooyin farsamo oo sarreeya oo qiimo sare leh.Inta badan guulaha tignoolajiyada cusub ee beerta birta ee 20-kii sano ee la soo dhaafay ayaa lagu dabaqay wax soo saarka birta dhuumaha.Isbeddelka horumarinta injineernimada dhuumaha waa dhexroor weyn oo tuubo, gaadiid gaas qani ah oo cadaadis sarreeya, qaboojin sare, deegaanka isticmaalka daxalka sare, iyo dhumucda derbiga dhuumaha badda hoose.Sidaa darteed, birta dhuumaha casriga ah waa inay lahaataa awood sare, saamaynta Bauschinger hooseeya, adkaanta sare iyo caabbinta jilicsanaanta, kaarboonka alxanka hooseeya iyo alxanka wanaagsan, iyo iska caabinta HIC iyo H2S.
Saxanadda birta ee dhuumaha waxaa loo isticmaalaa in lagu soo saaro tuubooyinka xariiqda alxanka ah, sababtoo ah tuubooyinka xariiqda aan kala go'a lahayn waxay ka samaysan yihiin bar wareegsan, ma aha taarikada birta.Saxan qaro weyn ayaa guud ahaan loo isticmaalaa si loo soo saaro gidaar qaro weyn oo tol ah oo toosan, birta gariiradda waxaa loo isticmaalaa in lagu soo saaro tuubo iska caabin ah oo koronto ah oo alxanka leh (RW) iyo tuubooyin isbiirsaday oo qulqulaya arc alxanka (SSAW).Maalmahan, dad badan oo macaamiisha ah waxay u baahan yihiin saxan bir ah oo bir ah si ay u soo saaraan tuubooyinka xariiqda sababtoo ah taarikada birta ayaa loo isticmaali karaa in lagu soo saaro tuubooyinka dhexroorka weyn, marka lagu daro, qiimaha tuubooyinka alxanka ah ayaa inta badan ka hooseeya tan tuubooyinka.
Saxanka birta ee birta ah waa wax muhiim ah oo loogu talagalay soo saarista tuubada khadka ERW, tuubada khadka LSAW, tuubada khadka SSAW, oo loo isticmaalo dhismaha khadka tuubada ee saliidda, gaaska iyo gaadiidka biyaha, waxaa loo isticmaali karaa wax soo saarka dhismaha gudbinta dareeraha cadaadiska.
Heerkulka arctic-ka aadka u hooseeya, cadaadiska xad dhaafka ah ee badda qoto dheer, warbaahinta aashitada: xitaa xaaladaha ugu daran wax saameyn taban ah kuma laha taarikada dhuumahayaga.Taarikada dhuumaha ayaa awood u leh inay ka shaqeeyaan qoto dheer ilaa 2,800 mitir oo ka hooseeya oogada badda.
Waxa kale oo aanu bixinaa saxan dhismeed bir ah oo isku duuban oo leh dahaadh u adkaysta daxalka ee baahida ugu badan ee codsiga gaaska-dhanka.Khabiir ahaan tignoolajiyada casriga casriga ah ee ku-wareejinta qaboojinta, waxaanu ka mid nahay hoggaamiyeyaasha warshadaha adduunka.
