Su'aalaha Badiya La Weydiiyo

1. Waa maxayTuubooyinka birta ah ee ASTM A252 Fasalka 3aad?
Tuubooyinka birta ah ee ASTM A252 heerka 3aad waa tuubooyin bir ah oo qaab-dhismeed ah oo la alxami karo si loogu isticmaalo taageero aasaas qoto dheer oo hoos yimaada dhismayaasha, buundooyinka, dekedaha, iyo injineernimada badda. Waxaa jira laba hab oo alxami ah oo loogu talagalay tuubooyinkan: tuubooyinka alxamida ee ku hoos jira helical (SSAW) ama tuubada alxamida ee ku dhex jirta dhererka (LSAW/EFW).

2. Cabbirrada iyo dhererka noocee ah ayaa la heli karaa?
Dhexroorka dibadda: 219 mm - 3000 mm (cabirka dhexroorka weyn ee XXL/waa la heli karaa) Dhumucda derbiga: 6-40 mm. Dhererka kaydka caadiga ah waa 6 mitir iyo 12 mitir, dherer gaar ahna waa la bixin karaa haddii la codsado.

3. Waa maxay heerarka agabka iyo sifooyinka farsamada?
Heerka Agabka: ASTM A252 Fasalka 3aad
Xoogga Wax Soo Saarka: ≥345 MPa
Xoogga jiidista: 455~620 MPa
Kordhinta: ≥20%%

4. Ma heli karaa shahaado tayo leh iyo warbixinno kormeer ah?
Haa, dhammaan tuubbooyinka birta ah waa kuwo shahaado haysta oo ISO 9001 haysta. Dhammaan dukumentiyada loo baahan yahay oo ay ku jiraan warbixinnada dhinac saddexaad ee ka imanaya SGS, BV ama hay'ad kale oo la aqoonsan yahay.

5. Sidee loo xirxiraa tuubbooyinka birta ah?
Waxay ku xidhaa tuulmooyinka tuubooyinka birta ah faashad bir ah oo ay ku go'doomisaa alwaax iyada oo aan waxyeello soo gaarin. Dahaarka ilaalinta/duubista ama/iyo daawaynta dusha sare ee kor ku xusan ayaa lagu talinayaa iyadoo loo eegayo baakadaha rarista. Baakad gaar ah ayaa la heli karaa.

6. Waa maxay wakhtiga keenista?
Waqtiga rarista: 15-30 maalmood ka dib xaqiijinta dalabka (waxay kuxirantahay tirada, qeexitaannada iyo meesha loo socdo).

7. Ma suurtogal baa in la sameeyo cabbirro gaar ah?
Haa, dhexroorka, dhumucda derbiga waxaa loo habeyn karaa iyadoo loo eegayo shuruudaha gaarka ah ee macaamiisha.
