Hauv kev tsim cov kua dej, cov nroj tsuag petrochemical, thiab kev tsim kho kev lag luam maritime, cov kav dej uas txuas thiab txhawb nqa cov hlab ntsha yog qhov tseem ceeb ntawm cov hlab ntsha lawv tus kheej. Kev thauj cov pa roj los yog cov kua dej cryogenic yuav tsum muaj cov khoom siv tubing uas muaj qhov tshwj xeeb weldability, qhov kub thiab txias resilience, thiab siab tawg siab.
Cov pa roj carbon monoxide yuav ua rau muaj kev phom sij txaus ntshai ntawm sub- xoom kub, thiab stainless hlau feem ntau hnyav hnyav thiab kim. Qhov no yog qhov uas 5xxx series siab -magnesium alloys kauj ruam hauv . 5083 thiab 5086 txhuas kav tau tshwm sim raws li qhov kev xaiv tseem ceeb rau siab - kev ua haujlwm siab piping, muab kev sib koom ua ke zoo ntawm lub zog siab - rau - qhov hnyav piv, marine - qib cryogenic tsis kam, thiab flaw.
Nrhiav cov kav dej txhim khu kev qha rau koj qhov project nkoj siab? Tsis txhob pheej hmoo cov khoom tsis ua hauj lwm. Hu rau GNEE pab pawg engineering hnub no. Xa koj daim nqi ntawm Cov Khoom Siv (BOM) rau kev sib tw nqe lus hauv 24 teev, ua tiav nrog EN 10204 3.1 MTC cov qauv.
Hais txog 5083 Aluminium Pressure Pipe
Alloy 5083 muaj cov ntsiab lus magnesium ntau dua (4.0% - 4.9%), uas ua rau nws muaj zog tshaj plaws ntawm cov qauv uas tsis yog- tshav kub- kho tau aluminium alloys.
Thaum tau teev tseg raws li 5083 aluminium siab yeeb nkab, cov hlau no tso siab rau cov tshuaj tiv thaiv kom muaj zog thiab tawv tawv es tsis yog kev kho cua sov. Nws qhov txiaj ntsig tseem ceeb hauv cov tshuab siab yog nws lub peev xwm los tiv taus siab dua sab hauv, tso cai rau cov kws ua haujlwm tsim cov kav dej nrog cov phab ntsa nyias nyias. Qhov no txo qhov hnyav tag nrho ntawm cov kav dej tsis muaj kev cuam tshuam txog kev nyab xeeb.
Tsis tas li ntawd, 5083 muaj cov manganese ntxiv (0.4% - 1.0%), uas ua kom zoo dua cov qauv nplej thiab txhim kho pob txha tawv, ua rau nws tiv taus kev ntxhov siab heev - corrosion cracking nyob rau hauv hnyav industrial puag ncig.
Hais txog 5086 Seamless Aluminium Tube
Alloy 5086 nta magnesium tsawg dua (3.5% - 4.5%). Thaum nws muaj qhov qis dua qhov kawg tensile lub zog piv rau 5083, nws ua tau zoo hauv kev tsim thiab ductility.
A 5086 seamless txhuas raj yog qhov kev xaiv zoo tshaj plaws rau cov kav dej sib txuas uas yuav tsum tau siv dav CNC raj dabtsi yog khoov, flaring, thiab routing nyob ib ncig ntawm lub nkoj nruj geometries. Cov ntsiab lus magnesium qis me ntsis ua rau 5086 alloy tiv taus tawg thaum ua haujlwm hnyav. Nws muab qhov zoo tshaj plaws tshuav nyiaj li cas: nws muaj zog txaus kom tau raws li ASME cov lej siab tab sis ductile txaus los ua kom yooj yim fabrication thiab txo nqi installation.

Kev daws cov ntsiab lus mob ntawm 5086/5083 Marine-Qib Aluminium Piping Systems
Vim li cas cov engineers hloov los ntawm cov hlau mus rau 5083/5086 txhuas kav rau kev siv lub nkoj siab? Cov khoom siv ncaj qha daws peb qhov teeb meem kev lag luam tseem ceeb:
1. Exceptional Cryogenic Toughness (Kau rau -196 degree)
Cov pa roj carbon steel raug kev txom nyem los ntawm ductile - mus rau - nkig hloov ntawm qhov kub thiab txias, ua rau nws muaj kev nyab xeeb txaus ntshai rau cov kua cryogenic . 5086 txhuas yeeb nkab rau cov hlab ntsha cryogenic thiab 5083 piping tswj lawv cov ductility thiab ua kom muaj zog tawm los ntawm qhov kub thiab txias. Qhov no ua rau lawv tus qauv tsis sib haum xeeb rau kev thauj Liquefied Natural Gas (LNG ntawm -162 degree), Liquid Nitrogen (LN₂ ntawm -196 degree), thiab Liquid Oxygen (LOX).
2. Weld Integrity thiab Joint Strength
Cov kav dej muaj ntau pua lub welded pob qij txha (lub taub qab vuam, T-cov pob qij txha, thiab flanges). Ob leeg 5083 thiab 5086 muab kev sib txuas zoo dua siv cov txheej txheem GTAW (TIG) thiab GMAW (MIG). Qhov tseem ceeb tshaj, Thaum tshav kub kub-Kev cuam tshuam cheeb tsam (HAZ) nyob rau hauv cov hlau alloys khaws cov feem pua siab dua ntawm cov hlau lub hauv paus lub zog piv rau 6xxx series tshav kub- cov alloys kho tau, kom ntseeg tau tias cov kav dej yuav tsis poob ntawm cov seams.
3. Tsis sib haum xeeb Corrosion Resistance
Feem ntau hu ua "marine qib," cov qib siab -magnesium alloys muaj lub ntuj, tus kheej - kho oxide txheej. Lawv tau yooj yim tiv taus cov dej hiav txwv ntev ntev, cov khoom siv tshuaj vapors, thiab cov pa phem hauv huab cua yam tsis tas yuav muaj cov txheej txheem tiv thaiv kim lossis cov ntaub ntawv uas xav tau los ntawm cov kav dej carbon steel.
