Dhuumaha qaabka la habeeyey oo leh darajada Q345C/D/E iyo daawaynta dusha specail

1. Sharaxaada

Qaybta godan waxaa inta badan loo isticmaalaa qaab dhismeedka birta iyo warshadaha mishiinada, laakiin qaabka caadiga ah iyo darajada ma buuxin karaan meelo gaar ah;

Si loo waafajiyo baahida gaarka ah ee badan iyo ka badan, shirkadeena waxay isu diyaarineysaa inay bixiso xoogaa codsi degdeg ah sida soo socota:

1) qaab gaar ah sida tuubo oval ah, tuubo dheeman ah, tuubo rooti ah, tuubo qaabaysan

2) darajo cusub sida Q345B, Q345C, Q345D, Q355B, Q355C, Q355D, SS400, 304, 316, 310, 16Mo3, AL-6Xn iwm

3) Dusha sare sida epoxy primer, qarxinta xabada iwm

Q345A, Q345B, Q345C, Q345D, Q345E waa kala soocida darajooyinka tayada, koraya A ilaa E, inta badan waxaa sabab u ah faraqa.

heerkulka saamaynta ay sababto content ee microelements sida fosfooraska iyo baaruud, taas oo macnaheedu yahay heerkulka saamaynta waa

kala duwan iyo tuubo ka kooban sifooyin farsamo.

Darajada Q345A wax saamayn ah kuma laha; darajada Q345B waa shoog 20 darajo heerkulka qolka; darajada Q345C waa naxdin 0 darajo;

darajada Q345D waa -20 shoog; darajada Q345E waa -40 shoog. Heerkulka shoogga ee kala duwan, qiimaha shoogga sidoo kale waa

kala duwan.

Awoodda wax-soosaarka Q kama yara 345Mp. Heerka tayada ayaa tilmaamaysa cadadka walxaha wasakhda ah (kaarboon, manganese, silicon, baaruud,

fosfooraska. Waa curiyaha wasakhda ah ee birta ah), mar kasta oo ay sii socdaan A, B, C, iyo D, waxa yaraanaya waxa wasakhaysan.

3. Hantida Makaanikada

4. Daaweynta dusha sare:

Epoxy zinc-ka hodanka ku ah curiyaha

5. Q345 C/D/E codsiga:

1) Q345C biibiile aan xuduud lahayn waxaa inta badan loo isticmaalaa in hay'adaha farsamada, qalabka hydraulic, si ballaaran loo isticmaalo in kiimikaad, batroolka, dunta,

caafimaadka, cuntada, mishiinada iyo warshadaha kale, inta badan loo isticmaalo in warshadaha u adkaysta tuubooyinka daxalka u adkaysta, qaybaha dhismaha iyo qaybaha.

2) Q345D dhuunta birta ah ee birta ah ayaa inta badan loo isticmaalaa maraakiibta, kuleyliyeyaasha, weelasha cadaadiska, taangiyada kaydinta saliidda, buundooyinka, qalabka saldhigga korontada,

mashiinada qaadista iyo gaadiidka iyo qaybaha kale ee alxanka ah ee kale ee dhismaha.

3) Q345E tuubooyinka cryogenic waxaa loo isticmaalaa cadaadis sare iyo tuubooyinka heerkulka sare iyo qalabka sida dhirta korontada,

dhirta tamarta nukliyeerka, kuleyliyeyaasha cadaadiska sarreeya, kulayliyeyaasha heerkulka sarreeya iyo kuleyliyeyaasha. Q345E tube cryogenic ayaa leh

qayb godan waxaana loo isticmaalaa sida dhuumaha qaada dareeraha, sida dhuumaha qaada saliida, gaaska dabiiciga ah, gaasta, biyaha

iyo walxo adag oo gaar ah.

6. Qaybaha kale ee la habeeyey:

5. Q345 C/D/E codsiga:

Q345D dhuunta birta ah ee birta ah, Q345D tuubo bir ah, Q345D tuubo bir ah, Q345E tuubo bir ah oo bir ah, tuubo bir ah oo sarreeya

Qalabka bacriminta cadaadiska, tuubooyinka birta ee heerkulka hooseeya ee dhirta tamarta, dhirta kiimikada iyo kuleyliyeyaasha.
