ʻO nā paipu kila welded longitudinal i hoʻokaʻawale ʻia ma muli o nā mea i hana ʻia mai lākou, ko lākou manaʻo e hoʻohana ai, a me nā kūlana a lākou e mālama ai. ʻO ka maʻamau, nā paipu kila welded longitudinal e pili ana i nā kūlana maʻamau a me ka hoʻokaʻawale ʻana no Submerged-Arc Welded Steel Pipes.
Nā kūlana waiwai:
Hiki ke hoʻokaʻawaleʻia nā paipu kila welded longitudinal ma muli o nā mea i hanaʻia e lākou, e like me ke kila kalapona, ke kila kila, ke kila kila, a me nā mea'ē aʻe.
Nā kūlana hana:
Hiki i ke kaʻina hana hana o Submerged-Arc Welded Steel Pipes ke hahai i nā kūlana kikoʻī i hoʻonohonoho ʻia e nā hui e like me ka American Petroleum Institute (API), ka American Society for Testing and Materials (ASTM), a i ʻole nā hui ʻē aʻe a i ʻole nā hui kūlana honua e like me kēia: API 5L, API 5CT, ASTM 53, EN10217, DIN 2458, IS 3589, GB/T3091, GB/T9711, EN10217, EN10219

Nā Koina Noi: Hiki ke hoʻokaʻawale ʻia nā paipu welded longitudinal e pili ana i kona hoʻohana ʻana, e like me nā paipu aila a me ke kinoea, nā noi hana, a i ʻole ka hoʻohana ʻana i ka ʻoihana. E ʻoluʻolu e nānā i nā kūlana kikoʻī a me nā hoʻohālikelike e pili ana i kāu mau koi kikoʻī, no ka mea, ʻokoʻa paha lākou ma muli o ka ʻoihana a me ka ʻāina.
