AINA ZA BOMBA LA ASTM A53
ASTM A 53 inashughulikia bomba la chuma lisilo imefumwa na lililochochewa lenye unene wa kawaida wa ukuta. hali ya uso ni kawaida nyeusi na moto-dipped mabati. ASTM A 53 huzalishwa hasa kwa shinikizo na maombi ya mitambo, na pia hutumiwa kwa usafiri wa mabomba ya mvuke, maji, mstari wa gesi.
TABIA
Iliyoundwa kwa ajili ya kukunja, kupinda na kukunja, bomba la chuma cha kaboni A53 linafaa kwa kulehemu. Madaraja yanaashiria mali fulani ya kemikali na mitambo na inapaswa kuzingatiwa katika uteuzi.
UKUBWA
½" - 12" vikwazo vingine vinavyotegemea daraja. Saizi za hadi 26" OD zinapatikana kwa masharti machache.
Uainisho wa Kawaida wa Bomba, Chuma, Nyeusi na Iliyochovywa moto, Zinki-iliyopakwa, Imechomezwa na Isiyo na Mfumo. Vipimo hivi hufunika bomba la mabati nyeusi isiyo na mshono na iliyochomwa moto.
Maombi:
Kwa matumizi ya mitambo na shinikizo, na pia kwa kusafirisha mvuke, maji, gesi na nk.
Vyeti vya majaribio ya kinu vitatolewa kulingana na EN10204/3.1B .
Mirija itapitia mchakato usio na mshono au wa kulehemu. Vipimo vya mvutano, bend, na kujaa vitafanywa ili kuhakikisha kuwa lazima ifuate sifa za kiufundi za kiwango.
