Pono e mālama ʻia ka wela, ma ke ʻano maʻamau (he kaʻina hana o ka hoʻomehana ʻana ma luna o kahi mahana koʻikoʻi a laila hoʻomālili i kahi mahana haʻahaʻa).
ʻO ka paipu ʻōwili wela: ʻaʻole pono ka mālama wela.Ke mālama ʻia ka paipu ʻōwili wela, e mālama ʻia ka wela ma 1200 °F [650 °C] a i ʻole.
Paipu huki anu: e mālama ʻia ka wela ma 1200 °F [650 °C] a i ʻole ma hope o ke kaʻina hana huki anu.

I ka nānā ʻana i ka haku mele o ASTM A53 a me ASTM A106 paipu, hiki ke ʻike ʻia kekahi mau ʻokoʻa nui.Hōʻike ʻo ASTM A106 i kahi kikoʻī silicon (Si) ʻaʻole i emi iho ma mua o 0.10%, e hāʻawi ana i kāna hana i nā mahana kiʻekiʻe, e kūpono loa ia no ka hoʻohana ʻana i nā wahi wela kiʻekiʻe e like me nā mea i loko o ka ʻoihana petrochemical a me nā ʻōnaehana hoʻoili mahu.
No ka maʻiʻo kalapona (C), ua kuhikuhi ka maʻamau ASTM A53 i kahi palena haʻahaʻa haʻahaʻa, ʻoi aku hoʻi no nā māka A a me B no ke ʻano S a me ke ʻano E. ʻO kēia ka mea e kūpono ai nā paipu Type A53 no ka wili a me ka hana anu a no laila hoʻohana pinepine ʻia i ka hana a me ka wai. nā ʻōnaehana halihali, e like me nā paipu wai a me ke kinoea.
Ma ke ʻano o ka ʻike manganese (Mn), hāʻawi ʻo ASTM A106 i kahi ākea ākea no ka Grade B a me C, e hiki ai ke hoʻonui i ka maʻalahi i ka hana hana ʻoiai e hoʻomaikaʻi ana i ka ikaika.ʻO ka paipu A53, ma ka ʻaoʻao ʻē aʻe, ua kaupalena ʻia i kahi palena kiʻekiʻe loa no ka ʻike manganese, e hoʻomaʻamaʻa i ka paʻa i ka wā wili.
