Falanqaynta farsamada ee sanduuqa caadiga ah ee Jarmalka
Qeexidda iyo nidaamka caadiga ah ee sanduuqa caadiga ah ee Jarmalka
Gacmaha DIN waxay si gaar ah u tixraacaan qalabka tuubooyinka ee u hoggaansama heerarka DIN ee Jarmalka, oo ay ku jiraan qeexitaannada asaasiga ah sida EN 10242 iyo DIN 2980. Marka la barbardhigo heerarka qaranka (GB/T) ama heerarka Mareykanka (ASME), gacmo-gashiga DIN waxay leeyihiin shuruudo adag oo loogu talagalay dulqaadka dhumucda derbiga (±0.1mm) iyo saxnaanta dunta (ISO Darajada 7/1), iyagoo bixinaya faa'iidooyin badbaado oo muhiim ah oo ku saabsan nidaamyada tuubooyinka cadaadiska.
Nidaamkan shahaadada wuxuu u baahan yahay in dufcad kasta oo alaab ah ay yeelato calaamadda shahaadada TÜV Rheinland ama PED, taasoo muujinaysa in agabku uu ka gudbay tijaabooyin heerkul aad u daran oo u dhexeeya -196°C ilaa 600°C, iyo sidoo kale in ka badan 100,000 oo tijaabo oo culeys firfircoon ah. Koox kiimiko ah oo Jarmal ah ayaa muujisay in cimriga adeegga bushings-ka heerka Jarmalka ee warbaahinta aadka u aashitada badan uu afar jeer ka badan yahay badeecadaha caadiga ah.
Toolojiga codsiga ee xaaladaha warshadaha
Qaybta injineernimada tamarta, khaanadaha birta aan daxalka lahayn ee Jarmalka ee cabbirkoodu u dhexeeyo DN50 ilaa DN300 ayaa si weyn loogu isticmaalaa nidaamyada kaydinta iyo gaadiidka ee LNG. Shaabaddooda EPDM ee laba-lakabka ah waxay hubineysaa inaysan jirin daadasho ka dhacda deegaannada cryogenic ilaa -162°C. Madal Nordic oo ku taal xeebaha ayaa adeegsata khaanadaha si gaar ah loo dahaadhay, iyadoo si guul leh u adkeysaneysa deegaanka buufinta milixda ee Badda Waqooyi muddo 16 sano ah iyada oo aan la helin cillad daxalka.
Warshadaha wax soo saarka mashiinnada saxda ah waxay doorbidaan qalabka tuubooyinka qabow ee saxsan, sida dahaarka darbiga aadka u khafiifka ah ee 12mm ee loo isticmaalo nidaamyada hydraulic-ka baabuurta. Naqshadaynta darbiga gudaha ee loo habeeyey iyada oo loo marayo jilitaanka dareeraha ayaa yareysa cadaadiska oo yaraada 0.02MPa/km, taasoo ka caawinaysa baabuurta waaweyn ee tamarta cusub inay horumariyaan waxtarka tamarta 5%.
Aragtida Saddex-geesoodka ah ee faa'iidooyinka badeecada
Marka laga hadlayo xulashada agabka, heerka Jarmalka wuxuu farayaa birta aan miridhku lahayn ee 316Ti ama birta daawaha leh ee CrMo oo leh maaddada sulfur ee ≤0.002% (heerka qaranku waa 0.03%). Baaritaannada birta ayaa muujinaya in cabbirka badarka ee dahaarka heerka Jarmalka uu la mid yahay heerka ASTM 8 ama ka sareeya, taasoo si wax ku ool ah uga hortagaysa dillaaca daxalka cadaadiska. Ka dib markii loo cusbooneysiiyay alaabada heerka Jarmalka, hal warshad oo warshadaysan ayaa kordhisay muddada dayactirka laga bilaabo 3 bilood ilaa 18 bilood.
Naqshadeynta qaab-dhismeedka waxaa ku jira qeexitaannada isku xirka booltiga VDI 2230, oo leh muraayad Ra 0.8μm ah oo ku taal dusha sare ee flange-ka iyo shaabad koon ah oo 60° ah, taasoo keentay iska caabin cadaadis oo ka badan 300 bar. Xogta tijaabada ah ee isbarbardhigga ah waxay muujinaysaa in xaaladaha hawlgalka ee u dhigma, kala-guurka gariirka ee sanduuqa caadiga ah ee Jarmalka uu yahay saddex-meelood meel oo keliya badeecada caadiga ah ee Mareykanka.
Geedka go'aanka xulashada iyo waddada hirgelinta
Qaab qiimeyn badan oo arrimo badan leh ayaa loo baahan yahay si loo qiimeeyo iswaafajinta warbaahinta: Hastelloy C-276 waxaa loo door bidaa jawi aashito xooggan leh oo leh qiimaha pH ka hooseeya 2; dahaarka WC carbide ayaa loo baahan yahay warbaahinta ay ku jiraan walxaha adag. Shirkad semiconductor ah ayaa isticmaashay qaabkan falanqaynta warbaahinta si ay u doorato agabka una horumariso heerarka nadaafadda ee ISO Class 3.
Isugeynta magdhowga heerkulka cadaadiska iyo heerkulka waa in lagu xisaabiyaa iyadoo la adeegsanayo qaacidada ASME B31.3. Tuubada uumiga ee 150°C, ku dar 0.12mm oo dhumuc ah oo derbi ah 10kii baar ee cadaadis kasta. Tusaalooyin wax ku ool ah ayaa muujinaya in xulashada saxda ah ay yareyn karto isticmaalka tamarta nidaamka 8% waxayna yareyn kartaa waqtiga aan la qorsheyn ee shaqada.
Isbeddellada warshadaha iyo horumarinta tignoolajiyada
Bushings-ka caqliga badan, oo ku salaysan Warshadaha 4.0, ayaa caan noqday. Shirkad Jarmal ah ayaa soo saartay badeecad dareeme oo ku dhex jirta oo la socota cadaadiska iyo heerkulka waqtiga dhabta ah, iyadoo xogta ku shubaysa nidaamka SCADA shantii ilbiriqsiba mar iyada oo loo marayo hab-maamuuska Modbus si loo suurogeliyo dayactirka saadaasha. Xogta tijaabada ah waxay muujinaysaa heerka saxnaanta 98.7% ee digniinaha cilladaha.
Marka laga hadlayo wax soo saarka cagaaran, tiknoolajiyada dhalaalinta elektaroonigga ah waxay gaartay dhumuc filim passivation ah oo ka badan 3nm dusha sare ee badeecada. Marka lagu daro habka annealing-ka ee ku shaqeeya haydarojiin, raadadka kaarboonka ee hal bushing ayaa la dhimayaa 42%. Bushings-ka shahaadaysan ee eber-kaarboon ayaa la filayaa inay diyaar noqdaan marka la gaaro 2026, taasoo horseedaysa isbeddelka Tilmaamaha PED ee EU inay noqoto nidaam laba-xakamayn ah oo loogu talagalay qiiqa kaarboonka.
