ASTM A178 / A178M Cov qauv qhia tshwj xeeb npog cov qauv hluav taws xob {}}}}}}}}}} bead flues, boiler blues, boiler flues, thiab muaj kev nyab xeeb xaus. Cov hlau yuav tsum yog cov qhab nia a (qis}}}} {{{{{{manganese steel). Txhua txoj hlab yuav tsum xa mus rau kev kho cua sov tom qab vuam, ua raws li los ntawm txias. Cov hlau yuav tsum ua raws li cov carbon hais plaub, manganese, phosphorus, leej faj, thiab silicon. Cov qib C thiab D yuav tsum ua raws li kev yuav tsum tau ua rau lub zog, uas yog lub zog, tawm lub zog, thiab elongation. Cov ntaub ntawv yuav tsum tau ua kom tiaj, flange, nro, rov qab ua kom tiaj, thiab hydrostative (lossis siv hluav taws xob ntxiv). Tsaus xeem yuav tsum tau ua yog nug los ntawm tus neeg yuav khoom. Qhov tsawg kawg nkaus elongation muaj nuj nqis kuj tseem muab.
Lub tubing ntau thiab tsawg feem ntau yog cov khoom siv no yog 1/2 rau 57 mm], suav nrog rau cov phab ntsa qis dua. Tubing muaj lwm txoj kev muaj lwm qhov ntev tuaj yeem muab cov raj txheej ua kom ua tiav nrog txhua lwm cov kev xav tau ntawm cov lus qhia tshwj xeeb.
