3) Waxaa baaraya hay'ado awood leh sida CCIC, SGS, BV, iyo TUV, iyadoo la adeegsanayo baakado caadi ah oo badda ku habboon.

Xirmooyinka iyo Gaarsiinta

1. Baakad:Xargo bir ah si loogu maareeyo si fudud. Baloogyada alwaaxa ama dunnage-ka ayaa la geliyaa inta u dhaxaysa rarista si looga ilaaliyo waxyeelada inta lagu jiro rarista. Daawaynta dusha sare (ikhtiyaar): Rinjiga madow, saliidda miridhku, duubka filimka balaastikada ah. Tuubooyinka kulul ee galvanized-ka ah ayaa sidoo kale lagu dabooli karaa filim ilaalin ah oo dusha sare ah si ku meel gaar ah. Waxaan sidoo kale bixin karnaa baakado gaar ah.

2. Keenista:Dhererka caadiga ah ee kaydka: 6m, 12m. Dherer gaar ah oo ku habboon mashruucaaga. Ku habboon gaadiidka badda iyo tareenka iyo waddooyinka. Waqtiga wax soo saarka badanaa waa 15-30 maalmood ka dib marka la helo lacagta, keenista hore marka la eego tirada iyo qeexitaanka. Ku habboon in loo dhoofiyo adduunka oo dhan iyadoo la raacayo dukumentiyo buuxa (shahaadada kormeerka, liiska baakadaha, biilka rarista).

Tallaabooyinka Ka Hortagga:

1. Wiish ama fargeeto leh suun ama kabo dhuuban waa in loo isticmaalaa si looga fogaado isbeddelka tuubada ee ku jirta Gacan ku haynta Dadka.

2. Meel qabow, qalalan iyo hawo leh ku hay kaydinta, haddii kale miridhku wuu dhici doonaa ka hor inta aan la rakibin. Baakadaha waaweyn/culus ee aadka u badan, fadlan si adag u raac qawaaniinta rarista maxalliga ah.

Su'aalaha Badiya La Weydiiyo

1. Waa maxay tuubbooyinka birta ah ee ASTM A252 Fasalka 3aad?
Tuubooyinka birta ah ee ASTM A252 heerka 3aadwaa 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.
