Faahfaahinta Badeecada

Calaamadaha Alaabta

Dunida naqshadeynta iyo dhismaha injineernimada, lahaanshaha tuubooyin bir ah oo la isku halleyn karo oo kala duwan ayaa muhiim ah. Tuubada birta ah ee A252 GRADE 3 waxay si fiican ugu habboon tahay sharraxaaddan, taasoo ka dhigaysa mid ka mid ah noocyada tuubooyinka birta ee ugu isticmaalka badan warshadaha. Iyada oo leh xooggeeda sare iyo iska caabbinta daxalka, tuubadan birta ah waxay keenaysaa kacaan aan horay loo arag dhismaha dhuumaha bulaacadaha.

Tuubo bir ah oo A252 GRADE 3 ahwaxaa loo yaqaanaa xooggeeda sare ee jiidista, isagoo ka sarreeya noocyada kale ee tuubooyinka birta ah. Waxay leedahay iska caabin xoog badan iyo cadaadis, taasoo hubinaysa xasillooni qaab dhismeed oo heer sare ah. Sifadan ayaa si gaar ah muhiim u ah marka khadadka wasakhda la saaro culaysyo waaweyn si loo hubiyo waxqabad la isku halleyn karo oo waara. Xirfadlayaasha ku takhasusay injineernimada waxay ku kalsoonaan karaan tuubadan birta ah inay u adkaysato xaaladaha ugu adag.

Astaamo kale oo gaar ah oo ku saabsan tuubada birta ah ee A252 Grade 3 waa daawaynta dusha sare. Si loo hubiyo tayada ugu sareysa, tuubooyinka si taxaddar leh ayaa loo daaweeyaa si looga hortago oksaydhka iyo daxalka. Taas macnaheedu waa in tuubooyinku ay ka shaqayn karaan deegaanno aad u daxal badan sida badweynta, meelaha qoyan iyo warshadaha kiimikada iyada oo aan wax u dhimayn waxqabadkeeda. Adkeysiga dusha sare ee tuubooyinka ayaa ka dhigaya doorasho aad u fiican mashaariicda u baahan iska caabinta daxalka oo heer sare ah.

Kala duwanaanta tuubooyinka birta ah ee A252 Heerka 3 waxaa lagu caddeeyay codsiyadooda ballaaran. Marka laga soo tago saameynta ay ku leedahay dhismaha wasakhda, waxaa loo isticmaali karaa warshado kala duwan oo ay ku jiraan saliidda iyo gaaska, daaweynta biyaha iyo mashaariicda kaabayaasha dhaqaalaha. Kala duwanaantan ayaa ka dhigaysa doorashada koowaad ee injineerada iyo qandaraaslayaasha raadinaya xalal tuubooyin bir ah oo la isku halleyn karo oo wax ku ool ah mashaariicdooda.

Marka ay timaadobulaacadahaxariiqdhismaha, tuubooyinka birta ah ee A252 Heerka 3 ayaa ka soocan. Xooggeeda sare iyo iska caabbinta daxalka ayaa ka soocay tuubooyinka kale ee birta ah ee suuqa yaal. Markay doortaan noocan tuubo, injineeradu waxay ku kalsoonaan karaan in mashruucoodu uu u adkaysan doono imtixaanka waqtiga, iyagoo hubinaya waarta iyo waaritaanka naqshadeeda.

Marka la soo koobo, tuubada birta ah ee A252 GRADE 3 waa wax ka beddela dhismaha tuubooyinka wasakhda iyadoo leh qaab-dhismeedkeeda laba-geesoodka ah ee laalaaban ee biyaha hoostooda ku jira. Xooggeeda adag ee gaarka ah iyo iska caabbinta daxalka ayaa ka dhigaya doorasho ku habboon injineerada raadinaya xalal tuubooyin bir ah oo la isku halleyn karo oo kala duwan. Hadday tahay xasillooni qaab-dhismeed ama baahida loo qabo in la iska caabiyo jawi aad u daxal badan, tuubadan birta ah waxay dhaaftay filashooyinka. Qabso tuubada birta ah ee A252 GRADE 3 oo la kulan tayada aan la barbar dhigi karin ee ay ku keento shaqadaada injineernimo.
