Hiki ke hoʻokaʻawale i nā paipu kila maʻamau i ka ASTM American standard seamless steel pipes, DIN German standard seamless steel pipes, JIS Japanese standard seamless steel pipes, GB national seamless steel pipes, API seamless steel pipes a me nāʻano'ē aʻe e like me ko lākou kūlana. ʻOi aku ka maʻamau o ka ASTM American standard seamless steel pipes ma ke ao holoʻokoʻa, a ʻokoʻa ko lākou ʻano. ʻO nā palena kūpono o nā paipu kila ʻole o ka ASTMASTM a179/179m/sa179/sa-179m American standard seamless steel pipes are listed as follows

He kūpono no nā paipu kila i hoʻohana ʻia i nā mea hoʻololi wela tubular, condensers a me nā mea hoʻoili wela like.

Kaʻina hana paipu kila ʻole. E like me kona manufacturing kaʻina, seamless kila paipu ua maheleia i wela-owili seamless kila paipu, anu-kauo seamless kila paipu, punched a kikoo aku seamless kila paipu, a vertically extruded seamless kila paipu. Hoʻohana ʻia nā kaʻina hana ʻelua no ka hana ʻana i nā paipu kila liʻiliʻi maʻamau, ʻo ke anawaena he 8-406 maʻamau, a ʻo ka mānoanoa o ka pā he 2-25; ua hoʻohana ʻia nā kaʻina hana ʻelua e hana i nā paipu kila maʻemaʻe-ʻeleʻele nui, ʻo ke anawaena o ia mea he 406-1800, a ʻo ka mānoanoa o ka pā he 20mm-220mm. Ma muli o kona hoʻohana ʻana, hiki ke hoʻokaʻawale ʻia inā paipu kila ʻole no nā hale, nā paipu kila ʻole no ka wai, nā paipu kila ʻole no nā paila, apaipu kila maʻemaʻe no nā paipu aila.
