Muhtasari wa Bomba la Chuma lisilo na Mfuko la ASTM A312
Kiwango cha ASTM A312 kinashughulikia daraja la kawaida la bomba la chuma cha pua. Bomba la ASTM A312 lina vipengele vya aloyi kama chromium, nikeli, shaba, molybdenum, n.k, ambayo huwapa ustahimilivu bora na upinzani dhidi ya midia babuzi na oksidi katika usanidi unaosababishwa na mkazo. Daraja linalofaa zaidi linashughulikia bila imefumwa, aina mbalimbali za baridi kali zilizotengenezwa kwa chuma cha pua cha austenitic na moduli za bomba moja kwa moja za weld. Bomba la Ratiba 40 la ASTM A312 limekusudiwa kutumika katika halijoto ya juu na huonekana kwa kawaida katika mifumo ya shinikizo la wastani. Bomba la sch 40 ni ratiba ya kawaida bomba hili linapatikana kwenye tasnia. Bomba la ASME SA12 ni daraja la bomba la chombo lenye shinikizo lililoundwa kwa ajili ya kuweka shinikizo la juu na halijoto. Moduli hizi zina nguvu nzuri na hazipindi au kupotosha kwa urahisi katika hali yoyote.

Aina za Utengenezaji wa Bomba za ASTM A312
l Bomba Isiyo na Mfumo (SMLS): Hufunika bomba la chuma cha pua lisilo na mshono kwenye rolling ya moto au inayotolewa kwa baridi.
l Bomba la Svetsade (WLD): Imeunganishwa na mchakato wa kulehemu wa moja kwa moja ambao hauongezi chuma cha kujaza wakati wa kulehemu.
l Bomba Linalofanya Kazi Baridi (Bomba la HCW): Bomba zito linalofanya kazi kwa ubaridi ambalo hutumika kwa ubaridi wa kupunguzwa kwa si chini ya 35% ya unene wa kuta zote mbili, na kuchomezwa kwenye bomba lililosuguliwa kabla ya kuchujwa mara ya mwisho. Usitumie fillers wakati wa kulehemu.
l Bomba lililosuguliwa na la HCW: Bomba lililochomezwa na bomba la HCW la 14 na dogo kuliko NPS 14 litakuwa na weld moja ya longitudinal. Baada ya idhini ya mnunuzi, bomba la svetsade na bomba la HCW lenye NPS kubwa kuliko NPS 14 litakuwa na weld moja ya longitudinal au litatengenezwa kwa kutengeneza na kulehemu sehemu mbili za longitudinal za hisa bapa. Kwa hivyo kila welds inapaswa kupimwa, kukaguliwa, kukaguliwa au kutibiwa.
