Dhuumaha Khadka Sare ee X65 SSAW: Xalka Tayada Sare ee Kaabayaasha Dhuumaha ee Waxtarka leh oo la isku halleyn karo
Soo bandhig:
Marka warshaduhu balaadhaan oo dadku koraan, baahida loo qabo gaadiid hufan oo saliid, gaaska dabiiciga ah, iyo agabka kale ayaa noqda mid sii kordheysa oo muhiim ah.Dhismaha iyo dayactirka kaabayaasha dhuumaha ayaa door muhiim ah ka ciyaara hubinta qulqulka kheyraadka adduunka oo aan kala go 'lahayn.Arrintan la xiriira,X65 SSAW dhuunta xariiqdaayaa u soo baxday sidii xal goyn ah, oo keenaya tayada sare iyo hufnaanta aan la soo koobi karin ee hawlaha dhuumaha.

Waa maxay x65 spiral tubbada xadhkaha alxanka hoostiisa?
X65 SSAW (Qalabka welded) ee tuubada khadka waa nooc ka mid ah tuubooyinka birta ee si weyn loo isticmaaloDhuumahadhismaha warshadaha saliidda iyo gaaska.Isku darka tuubada khadka ee xoogga, adkeysiga iyo waxqabadka cajiibka ah ayaa ka dhigtay doorashada koowaad ee mashaariic kala duwan oo adduunka ah.
Xoog iyo adkeysi:
Mid ka mid ah astaamaha muhiimka ah ee kala saara x65 spiral submerged arc tubbada xariiqda xariiqda ayaa ah xooggeeda gaarka ah iyo cimri dhererkeeda.Ka samaysan bir tayo sare leh, waxay leedahay iska caabin adag oo cadaadis gudaha iyo dibadda ah.Tani waxay ka dhigaysaa doorashada ugu fiican ee dalbanaya codsiyada saliidda iyo gaaska, hubinta kaabayaasha la isku halleyn karo oo waara.
Waxtarka dhuumaha shaqada:
Hufnaantu waa arrin muhiim ah marka la soo qaadayo agabka dhuumaha.X65 SSAW tuubada xariiqda ayaa aad uga fiican aaggan, taasoo bixisa qulqulka qulqulka ugu yar, taas oo yaraynaysa isticmaalka tamarta inta lagu jiro gaadiidka.Waxtarkani waxa uu caawiyaa in la badbaadiyo kharashaadka iyo in la yareeyo saamaynta deegaanka, samaynta doorashada deegaanka saaxiibtinimo.

a.Habka deoxidation waxaa loo qoondeeyey sida soo socota: FF: Bir si buuxda loo dilay oo ay ku jiraan curiyayaasha isku xidha nitrogen ee xaddi ku filan in lagu xidho nitrogen la heli karo (tusaale min. 0,020 % wadarta Al ama 0,015 % Al milmaya). b.Qiimaha ugu sarreeya ee nitrogen ma khuseeyo haddii ka kooban yahay kiimikaad uu muujiyo wadarta guud ee Al content ee 0,020 % leh ugu yaraan Al/N saamiga 2:1, ama haddii ku filan walxo kale oo N-xidhitaan ah ay joogaan.Qodobbada N-ku-xidhan waa in lagu diiwaangeliyaa Dukumeentiga Kormeerka. |
U adkaysta bay'ada adag:
Shabakadaha dhuumaha qaada waxay maraan deegaanno kala duwan, oo ay ku jiraan bay'ad qallafsan oo daxalaysa.X65 spiral submerged arc welded tube line ayaa caddeeyey inay ka sarreyso xaaladahan oo kale sababtoo ah caabbinta aadka u fiican ee daxalka, xoqidda iyo arrimo kale oo dibadda ah.Iska caabbintani waxay hubisaa daacadnimada nidaamka tuubooyinka, waxay yaraynaysaa kharashka dayactirka, waxayna yaraynaysaa halista daadinta ama guuldarada.
ASD:
Joogitaanka hawlaha dhuumaha ee nabdoon waa muhiim.Tuubada xariiqda X65 SSAW waxay mudnaan siisaa badbaadada iyagoo keenaya sifooyin farsamo oo aad u wanaagsan iyo saxnaanta cabbirka.Iyada oo la adeegsanayo tillaabooyinka xakamaynta tayada adag, dhuumaha ayaa ilaalinaya sharafta qaabdhismeedka loo baahan yahay si ay ugu adkeystaan cadaadiska sare iyo xaaladaha adag ee shaqada, hubinta amniga shaqaalaha iyo kheyraadka.
Gabagabadii:
X65 SSAW tuubada xariiqda waxay u taagan tahay sidii xal sare ee dhismaha iyo dayactirka kaabayaasha dhuumaha.Xooggeeda, adkeysigeeda, hufnaanteeda iyo iska caabbinta bay'ada adag ayaa ka dhigaysa doorasho aad u wanaagsan warshadaha saliidda iyo gaaska iyo warshadaha kale ee ku tiirsan gaadiidka waxtarka leh.Dhuumaha khadka ee X65 SSAW waxay gacan ka geysataa kaydinta kharashka, waaritaanka deegaanka iyo hubinta badbaadada, taasoo ka dhigaysa hanti lama huraan u ah hawlgallada dhuumaha ee doonaya inay noqdaan kuwo la isku halayn karo oo hufan.
Sidaa darteed, haddii aad bilaabayso mashruuca tuubooyinka, tixgalinta x65 SSAW tuubada xariiqda waa doorasho caqli-gal ah oo dammaanad qaadaysa waxqabad sare iyo guul mustaqbalka fog ah.Maalgelinta xalkan tayada sare leh oo markhaati ka noqo saamaynta isbeddelka ah ee ay ku yeelan karto kaabayaasha dhuumahaaga.
