"PIPE ALLOY STEEL HTASTM A335 GR P22- SCH 80 . ʻO ASME B36.10 PLAIN ENDS (QUANTITIES UNIT : M)" he pūʻulu o nā kikoʻī ʻenehana e wehewehe ana i nā paipu kila hao.

PIPE ALLOY STEEL HT:
"PIPE" 'o ia ho'i ka paipu, a 'o ka "ALLOY STEEL" 'o ia ho'i ke kila kila. ʻO ke kila kila he kila i loaʻa i hoʻokahi aʻoi aʻe paha nā mea hoʻohui (e like me ka chromium, molybdenum, tungsten, a me nā mea'ē aʻe) a loaʻa iā ia nā waiwai maikaʻi e like me ke kiʻekiʻe o ka mahana wela, ke kūpaʻa o ka corrosion a me ka ikaika.

ʻO ka "HT" ka mea maʻamau e pili ana i nā koi wela kiʻekiʻe, e hōʻike ana ua kūpono kēia kila paipu no nā wahi wela kiʻekiʻe.

ASTM A335 GR P22:
He wehewehe kēia o ke kūlana a me ka pae o nā mea paipu.

ASTM A335he maʻamau i hoʻomohala ʻia e ka American Society for Testing and Materials (ASTM) no nā paipu kila kila ʻole, ʻoi aku hoʻi no nā kaiapuni kiʻekiʻe a me ke kaomi kiʻekiʻe.
ʻO GR P22 ka papa kikoʻī kikoʻī ma lalo o kēia maʻamau, kahi e hōʻike ai ʻo "P22" i ka haku mele a me nā koi hana o ka mea paipu. ʻO ke kila kila P22 ka mea maʻamau i loaʻa nā mea chromium (Cr) a me molybdenum (Mo), loaʻa ka ikaika kiʻekiʻe kiʻekiʻe a me ka pale ʻana i ka corrosion, a kūpono i nā wahi wela kiʻekiʻe.
SCH 80:
E pili ana kēia i ka mānoanoa o ka pā o ka paipu, a ʻo "SCH" ka pōkole o "Schedule".

SCH 80 'o ia ho'i he mānoanoa ka mānoanoa o ka pā o ka paipu a hiki ke pale aku i ke kaumaha o loko. No nā paipu SCH 80, ʻoi aku ka nui o kona mānoanoa o ka pā ma waena o nā paipu o ke anawaena like, hiki ke hoʻonui i kona hiki ke hoʻoikaika a me ka pale ʻana i ka hopena.
ASME B36.10:
He maʻamau kēia i hoʻomohala ʻia e ka American Society of Mechanical Engineers (ASME) e kuhikuhi ana i ka nui, ke ʻano, ka hoʻomanawanui, ke kaumaha a me nā koi ʻē aʻe o nā paipu kila. B36.10 kikoʻī kikoʻī i ke anawaena o waho, ka mānoanoa o ka paia a me nā palena ʻē aʻe o ke kila kalapona a me ke kila kila paipu ʻole a me nā paipu welded e hōʻoia i ka standardization a me ke kūlike o nā huahana pipeline.

HOPE PLAIN:
ʻO ka "Plain Ends" e pili ana i nā paipu me ka ʻole o ka mīkini a i ʻole ka hopena pili, maʻamau me nā ʻaoʻao ʻoki maʻemaʻe. Ke hoʻohālikelike ʻia me nā paipu me nā pili threaded a flanged paha, hoʻohana mau ʻia nā paipu hopena maʻamau i nā noi kahi e pono ai nā pilina welded.

NUI: M:
Hōʻike kēia i ka ʻāpana o ke ana o ka huahana he "mika", ʻo ia hoʻi, ana ʻia ka nui o ka paipu ma nā mika, ʻaʻole nā ​​ʻāpana a i ʻole nā ​​​​hui ʻē aʻe.

ʻO ka paipu i ho'ākākaʻia ma kēia weheweheʻana he paipu kila kila kiʻekiʻe e kū ana i ka maʻamau ASTM A335 GR P22, me ka mānoanoa o ka pā o SCH 80 a kū i ke kūlana nui o ASME B36.10. ʻO nā wēlau o ka paipu maʻemaʻe (ʻaʻohe wili a i ʻole flanges), ua ana ʻia ka lōʻihi i nā mika, a kūpono ia no nā ʻōnaehana paipu i ke kiʻekiʻe o ka wela, ke kaomi a me nā wahi corrosive.
