ASTM A106
Inofanirwa kubatwa nekupisa, kazhinji neyakajairwa (maitiro ekupisa pamusoro petembiricha yakakosha uyezve kutonhora kusvika kune mwero tembiricha).
Hot rolled pombi: haidi kurapwa kwekupisa.Kana pombi yakakungurutswa inopisa ichigadziriswa kupisa, inofanira kugadziriswa kupisa pa1200 ° F [650 ° C] kana kupfuura.
Pombi inodhonzwa nechando: ichabatwa nekupisa pa1200 °F [650 °C] kana kupfuura mushure mekupedzisira kutonhora kwekudhirowa.
ASTM A53
Type E, Grade B, uye Type F, Grade B: ichabatwa kupisa mushure mewelding kusvika 1000 °F [540°C] kuitira kuti pasave neuntempered martensite iripo, kana neimwe nzira inorapwa kuitira kuti pasave neuntempered martensite iripo.
Rudzi S: Kurapa kwekupisa hakudiwi pombi isina musono.
