ʻO ASTM A335 P22 kahi ʻāpana o ASTM A335. ʻO ka ASTM A335 P22 paipu kila kila e kūpono no ke kuʻo ʻana, flanging, a me nā hana hana like, a no ka hoʻohui ʻana. E kūlike ka mea kila i ka haku mele ʻana, ka waiwai tensile, a me nā koi o ka paʻakikī.
ʻO kēlā me kēia lōʻihi o ka paipu e kau ʻia i ka hoʻāʻo hydrostatic. Eia kekahi, e nānā ʻia kēlā me kēia paipu e kahi ʻano hoʻokolohua non-destructive e like me nā hana i koi ʻia.
ʻO ka laulā o ka nui o ka paipu ASTM A335 P22 i hiki ke nānā ʻia e kēlā me kēia ʻano hana e kau ʻia i nā palena i ka pae o ka hana.

No nā mea wela i mālama ʻia i loko o ka umu ahi ʻano pū, e hoʻāʻo ʻia ma ka 5% o ka paipu mai kēlā me kēia ʻāpana i mālama ʻia. No nā ʻāpana liʻiliʻi, e hoʻāʻo ʻia ma kahi o hoʻokahi paipu.
No ka wela wela i mālama ʻia e ke kaʻina hana mau, e hana ʻia nā hoʻāʻo ma ka helu kūpono o ka paipu e lilo i 5% o ka hailona, akā ʻaʻole i emi iho ma mua o 2 paipu.
Nā memo no ka ho'āʻo ʻo Bend:
No ka paipu nona ka anawaena i oi aku i ka NPS 25 a o kona anawaena me ka manoanoa o ka paia he 7.0 a emi mai paha e hoao ia i ka hoao piko ma kahi o ka hoao palahalaha.
Hiki ke hā'awi 'ia ka paipu 'ē a'e i like ke anawaena a 'oi aku paha ma mua o NPS 10 ma kahi o ka ho'ā'o palahalaha ma muli o ka 'ae o ka mea kū'ai.
