ASTM A192 (ASME SA192) he paipu kila kalapona humuhumu ʻole i hoʻohana ʻia i nā wahi mahana kiʻekiʻe a me ke kaomi kiʻekiʻe a hoʻohana nui ʻia i loko o nā paila a me nā mea hoʻololi wela.
Anawaena waho: 1/2″ – 7″ (12.7 mm – 177.8 mm);
Mānoanoa o ka paia: 0.085″ – 1.000″ (2.2 mm – 25.4 mm);
Hiki ke hoʻolako ʻia nā paipu kila ʻē aʻe e like me ka mea e pono ai, ke hoʻokō ʻia nā koi ʻē aʻe a pau o A192.
Hana ʻia ʻo ASTM A192 me ka hoʻohana ʻana i kahi kaʻina hana maʻalahi a hoʻopau ʻia me ka wela a hoʻopau anu paha e like me ka mea e pono ai;
Eia kekahi, pono e hōʻike ka ʻike ʻana o ka paipu kila inā ua hoʻopau wela ʻia ka paipu kila a i ʻole ua hoʻopau anu ʻia.
Hoʻopau welaʻO ke ʻano: Pili i ke kaʻina hana o ka hoʻopau ʻana i nā ana hope loa o ka paipu kila i ke kūlana wela. Ma hope o ka hala ʻana o ke kaʻina hana wela o ka paipu kila e like me ka ʻōwili wela a i ʻole ke kaha kiʻi wela, ʻaʻole ia e hana hou ʻia i ke anu. ʻOi aku ka paʻakikī a me ka ductility o nā paipu kila i hoʻopau ʻia i ka wela akā he mau ʻae ʻana i ka nui.
Ua pau ke anuHana ʻia ka paipu kila i kona ana hope loa e nā kaʻina hana anu e like me ka ʻōwili anu a i ʻole ke kahakiʻi anu ʻana ma ka mahana o ka lumi. ʻOi aku ka pololei o nā ʻae ʻana o ka ana o nā paipu kila i hoʻopau anu ʻia a me nā ʻili laumania akā hiki ke mōhai i kekahi paʻakikī.
ʻAʻole pono ka mālama wela i nā paipu kila humuhumu i hoʻopau ʻia me ka wela.
Hoʻomehana ʻia nā paipu kila humuhumu ʻole i hoʻopau anu ʻia ma nā mahana o 1200°F [650°C] a ʻoi aku paha ma hope o ka mālama anu hope loa.
