ASTM A213 Tubu tal-Bojlers tal-Azzar li ma jissaddadx

ASTM A213/ASME SA213 ikopri pajpijiet tal-azzar liga baxxi u ħxuna minima tal-ħajt, ħadid u azzar awstenitiku mingħajr saldi,bojler u tubi super-heateru tubi ta' skambjatur tas-sħana tal-azzar awstenitiċi, gradi TP304, TP304H, TP304L, TP310S, TP310HCbN, TP316, TP316H, TP316H, TP316L eċċ.

Gradi TP304H, TP309H, TP309HCb, TP310H, TP310HCb, TP310HCbN, TP316H, TP321H, TP347H, TP347HFG (qamħ fin) u TP348H huma modifiki ta' GradI TP34, TP3404, TP347HFG (qamħ fin) u TP348H huma modifiki ta' Grad TP3404, TP3404343G (qamħ fin) u TP348H huma modifiki ta' GradI 43404, TP3404, TP347HFG (qamħ fin) u TP348H huma modifiki ta' Gradi TP343404, TP340434 TP309S, TP309Cb, TP310S, TP310Cb, TP316, TP321, TP347, u TP348, u huma maħsuba għal servizz ta' temperatura għolja, bħal dawk għas-supersedjaturi u t-teħid lura.

Għal ASTM A213 Tubi mingħajr saldatura b'dijametri ta' inqas minn 1/8 ġewwa .[3.2 mm] fid-dijametru intern jew 0.015 fi. [0.4 mm] fi ħxuna, rekwiżiti ta' proprjetà mekkanika mhux se japplikaw. Tubu b'dimensjonijiet oħra jista' jiġi fornut jikkonforma ma' ħtiġiet oħra.
