Bomba la chuma la ASTM A213
ASTM A213 inashughulikia boiler ya chuma isiyo na mshono ya ferritic na austenitic, Boiler Tube, na mirija ya kubadilishana joto, iliyoteuliwa Daraja la T5, TP304, n.k. Madaraja yaliyo na herufi, H, katika uteuzi wao, yana mahitaji tofauti na yale ya darasa sawa na isiyo na herufi. , H. Mahitaji haya tofauti hutoa nguvu ya juu zaidi ya kupasuka kuliko inavyoweza kufikiwa katika viwango sawa bila mahitaji haya tofauti.
Ukubwa wa neli na unene kawaida hutolewa kwa spishi hiifimawasiliano ni 1⁄inchi 8. [milimita 3.2] kwa kipenyo cha ndani hadi inchi 5. [milimita 127] kwa kipenyo cha nje na inchi 0.015 hadi 0.500. [0.4 hadi 12.7 mm], ikijumuisha, katika unene wa chini zaidi wa ukuta au, ikiwa ni maalum.fied kwa mpangilio, unene wa wastani wa ukuta.Mirija yenye vipenyo vingine inaweza kuwekwa, mradi mirija hiyo inatii mahitaji mengine yote ya spishi hiification.

(1) mirija ya chuma iliyokamilishwa kwa ferritic haitaweza kupimwa na inafaa kwa ukaguzi, mlima kidogo wa oxidation sio kipimo cha kuzingatia.
(2) Mirija ya chuma iliyokamilishwa na aloi ya ferritic haitakuwa na mizani iliyolegea na inafaa kwa ukaguzi.
(3) Mirija ya chuma cha pua itachunwa bila kipimo, wakati uchujaji mkali unapotumika, kuchuna si lazima.
(4) Sharti lolote maalum la kumalizia litakuwa chini ya makubaliano kati ya msambazaji na mnunuzi.
