Paipu kila kalapona humuhumuʻO nā kūlana he mea nui ia i ka hōʻoia ʻana i ka maikaʻi, ka kūlike a me ka palekana o kēia mau paipu i nā ʻano hana like ʻole. Hāʻawi kēia mau kūlana i ke alakaʻi no nā mea hana, nā mea hoʻolako a me nā mea kūʻai aku e hōʻoia i ka hoʻokō ʻana o ka paipu i nā koi kikoʻī a kūlike me nā lula o ka ʻoihana.
ʻO kekahi o nā kūlana i ʻike nui ʻia no ka paipu kila humuhumu kalapona ʻo ia kaASTM A106/A106Mkūlana. Hoʻomohala ʻia e ka American Society for Testing and Materials (ASTM), kuhikuhi kēia kūlana i nā koi no ka paipu kila kalapona seamless no ka lawelawe wela kiʻekiʻe. Uhi ia i nā nui paipu NPS 1/8 a hiki i NPS 48 (DN 6 a hiki i DN 1200) a me nā mānoanoa o ka paia e like me ka mea i kuhikuhi ʻia ma ANSI B36.10.
Eia kekahi, ʻo ke kūlana paipu kila kalapona Seamless e komo pū me API 5L,ASTM A53, ASTMA179,ASTM A192,ASTM A210/SA210, ASTM A252, BS EN10210,JIS G3454a me JIS G3456.
Eia kekahi, ua komo pū ka maʻamau i nā koi no ka hoʻāʻo ʻana ʻaʻole luku, e like me ka hoʻāʻo ultrasonic, ka hoʻāʻo ʻana o ke au eddy a i ʻole ka hoʻāʻo hydrostatic, e hōʻoia i ka pono o ka pipeline. Hoʻoponopono pū ia i nā ʻano like ʻole e pili ana i ka hōʻailona, ka hoʻopili ʻana a me nā koi hōʻoia.
I ka hōʻuluʻulu manaʻo, ʻo nā kūlana paipu kila humuhumu kalapona, e like me ASTM A106/A106M, hāʻawi i nā alakaʻi e pono ai no ka hana ʻana, ka hoʻāʻo ʻana, a me ka kaohi ʻana i ka maikaʻi o kēia mau paipu. ʻO ka mālama ʻana i kēia mau kūlana e hōʻoiaʻiʻo ana e hoʻokō nā paipu i nā kikoʻī e pono ai, nā koi hana a me ka palekana, e hoʻonui ana i ko lākou hilinaʻi a me ke kūpono no nā ʻano ʻoihana like ʻole.
