Tuubooyinka Birta ASTM A671 CC65 CL 12 EFW: Tuubooyinka Alxanka ee Xoogga Sare leh ee loogu talagalay Codsiyada Warshadaha

Tuubo ASTM A671 CC65 CL 12 EFW ahwaa tuubo tayo sare leh oo EFW ah oo si weyn loogu isticmaalo nidaamyada dhuumaha saliidda, gaaska, kiimikada, iyo dhuumaha warshadaha guud. Tuubooyinkani waxay buuxiyaan shuruudahaHeerarka ASTM A671waxaana loogu talagalay gaadiidka dareeraha ee cadaadiska dhexdhexaadka ah iyo kuwa sare iyo codsiyada qaab-dhismeedka. Waxay bixiyaan alxan aad u fiican iyo sifooyin farsamo, taasoo ka dhigaysa kuwo ku habboon injineernimada dhuumaha warshadaha.

Qeexitaanka Agabka

Tuubooyinka waxaa laga soo saaraa dahaadh yarbirta CC65 oo xoog badan, halabuurka kiimikada si adag ayaa loo xakameeyaa si loo bixiyo alxanka ugu fiican, iska caabbinta daxalka iyo awoodaha heerkulka sare. Birtu waxay leedahay qaab-dhismeed isku mid ah oo hadhuudh ah waxayna buuxisaa baahida sare ee qaab-dhismeedka iyo cadaadiska loo isticmaalo warshadaha.
