Afar farqi oo waaweyn oo u dhexeeya tuubooyinka dheecaanka PVC A iyo tuubada B

Doorashada tuubooyinka A ama tuubooyinka B waa dhibaato caadi ah marka dadku wax iibsadaan Tuubooyinka PVC, laakiin dad yar ayaa si cad u sheegi kara farqiga gaarka ah ee u dhexeeya.

Soo koobid afar farqi oo aad u kala duwan tahay tixraacaaga:

1. Heerar kala duwan

Tuubada A: Tuubada A waxay aqbashaa heerka qaran ee GB/T 5836.1-2018 (heerka adag ee tuubada polyvinyl chloride (PVC-U) ee loogu talagalay daadinta dhismaha), kaas oo ah tuubo heer qaran ah;
Tuubada B: Tuubada B waxay qaadataa heerka ganacsiga waana tuubada caadiga ah ee ganacsiga;

2. Dhumucyo kala duwan

Tuubada A: Dhumucda derbiga ee tuubbada A waa mid dhumuc weyn leh, sida dhumucda derbiga ee tuubbada 50mm waa 2.0mm, dhumucda derbiga ee tuubbada 75mm waa 2.3mm, dhumucda derbiga ee tuubbada 110mm waa 3.2mm, dhumucda derbiga ee tuubbada 160mm waa 4.0mm, dhumucda derbiga ee tuubbada 200mm waa 4.9mm, iwm.
Tuubada B: Dhumucda derbiga ee tuubbada B waa mid khafiif ah, sida dhumucda derbiga ee tuubbada 50mm waa 1.8mm, dhumucda derbiga ee tuubbada 75mm waa 2.0mm, dhumucda derbiga ee tuubbada 110mm waa 2.8mm, dhumucda derbiga ee tuubbada 160mm waa 3.0mm.

3. Qiimo kala duwan

Tuubada A: Tuubada A waxay leedahay agab ka wanaagsan, dhumuc derbi oo badan, xoog sare, iyo qiimo sare;
Tuubada B: Tuubada B waxay leedahay budada kaalshiyamka oo sareysa, dhumuc yar oo derbi ah, xoog yar oo ka sii daran, iyo qiimo jaban;

4. Isticmaalo kala duwan

Tuubada A: Tuubada A waxaa badanaa loo isticmaalaa injineernimada biyo-mareenka iyo qiiqa oo leh baahiyo sare, waana dhif in loo isticmaalo guryaha.
Tuubada B: Tuubada B waxaa inta badan loogu talagalay injineernimada daadinta biyaha, qiiqa iyo isticmaalka guryaha iyadoo shuruudo yar la iska rabo;

Farqiga u dhexeeya Tuubada PVC Tuubada A iyo tuubada B waxay inta badan diiradda saaraan afarta qodob ee kor ku xusan. Waxaan rajeynayaa inay ku anfici doonto.
