ASTM A513 kilahe paipu kalapona a me ke kila kila a me ka paipu i hana ʻia mai ke kila wela a i ʻole ke kila i ʻōwili ʻia e like me ka mea maka ma ke kaʻina hana kuʻi kūʻē kūʻē (ERW), i hoʻohana nui ʻia i nā ʻano hana mechanical āpau.
ʻAno 5i loko o ka maʻamau ASTM A513 e pili ana i kaHuki ʻia ma luna o ka mandrel (DOM)paipu.
Hoʻokumu ʻia ka paipu DOM ma ka hana mua ʻana i kahi paipu welded a laila huki anu ʻia ma o ka make a ma luna o nā mandrels e hoʻopau i kahi hoʻomanawanui ʻoi aku ka nui a ʻoi aku ka maikaʻi o ka ʻili i hoʻohālikelike ʻia me nā ʻano paipu welded ʻē aʻe.
Kūlana hoʻokō: ASTM A513
Maikaʻi: ʻO ke kila wela a i ʻole nā mea anuanu
ʻAno:ʻAno1 (1a a i ʻole 1b), Type2, Type3, Type4, Type5, Type6.

e like me ka streamlined, hexagonal, octagonal, poepoe iloko a hexagonal a octagonal ma waho, ribbed in or out, triangular, poepoe rectangular, and D.
ʻO ka hao i ʻōwili wela a i ʻole ʻo Cold-rolled Steel
Hiki ke hana ʻia nā mea maka no ka hana ʻana o Hot-rolled a i ʻole Cold-rolled Steel e kekahi kaʻina hana.
Ke kila-wela: Ma ke kaʻina hana, hoʻomaʻamaʻa muaʻia ke kila wela i nā mahana kiʻekiʻe, e hiki ai ke'ōwiliʻia ke kila i loko o ke kūlana plastic, kahi e maʻalahi ai ke hoʻololi i keʻano a me ka nui o ke kila.I ka pau ʻana o ke kaʻina hana ʻōwili wela, hoʻonui pinepine ʻia ka mea a me ka deformed.
Steel-Rolled Steel: Hoʻowili hou ʻia ke kila ʻōwili anuanu ma hope o ka maʻalili ʻana o ka mea e loaʻa ai ka nui a me ke ʻano i makemake ʻia.Hana ʻia kēia kaʻina hana ma ka lumi wela a loaʻa i ke kila me ka maikaʻi o ka ʻili a me nā ana kūpono.
E hana ʻia nā paipu e kauila-kūʻai-welded (RW)kaʻina hana.
ʻO ka paipu ERW ke kaʻina hana o ka weld ma ka wili ʻana i kahi mea metala i loko o ka cylinder a hoʻohana i ke kūpaʻa a me ke kaomi ma kona lōʻihi.
Pono ke kila i nā koi hoʻohui kemika i kuhikuhi ʻia ma ka Papa 1 a i ʻole ka Papa 2.

ʻO nā paipu poepoe a me nā paipu i hana ʻia i nā ʻano ʻano ʻē aʻe i ka wā poepoe e pili ana.
E hāʻawi ʻia nā paipu āpau i kahi hoʻāʻo hydrostatic.
