Mahitaji ya Kiufundi ya Mirija ya Chuma ya Kaboni ya Mabati ya Moto
Mirija NBR 5590
Wao hutengenezwa na hutolewa kwa seams au bila, kwa ajili ya uendeshaji wa maji yasiyo ya babuzi. Zinatumika katika machining na vifaa vya mitambo, lakini zinaweza kutumika katika upitishaji wa mvuke, maji, gesi na hewa iliyoshinikwa.
Kiwango cha Brazili - NBR 5590 cha mirija ya chuma, kilichapishwa na Chama cha Viwango vya Kiufundi cha Brazili, ABNT, kwa lengo la kudhibiti uzalishaji na usambazaji wa Mirija ya Ratiba. Mirija hii hutengenezwa kwa chuma cha kaboni, na kulehemu kwa muda mrefu, nyeusi au mabati, kwa lengo la kufanya maji yasiyo na babuzi chini ya shinikizo, joto na matumizi maalum ya mitambo, ingawa pia hutumiwa kwa matumizi ya kawaida ya kufanya mivuke, gesi, maji na. hewa iliyoshinikizwa. Mirija hii ya chuma hupata uthibitisho wa lazima baada ya kufanya vipimo vya maabara vya usalama na ufanisi. Kwa vipimo maalum, aina hii ya tube hutumiwa katika matumizi ya mitambo na machining. Kiwango sawa: ASTM A53.
Vipimo vya Kiufundi | |
• Nyenzo | Chuma cha kaboni kilichochomwa moto; |
