ʻO ka wehewehe pololei ʻana i ka nui o kahi paipu kila e pono e hoʻokomo i nā ʻāpana koʻikoʻi:
Anawaena waho (OD)
ʻO ke anawaena o waho o ka paipu kila, i hōʻike pinepine ʻia e like me ke anawaena nominal (DN) a i ʻole ka nui paipu nominal (NPS).
Nui Pipe Nominal (NPS) vs. Anawaena Nominal (DN)
ʻO ka NPS ka nui inoa ma muli o nā iniha, ʻoiai ʻo DN ke anawaena nominal i millimeters.He mea maʻalahi ka pilina hoʻololi: ua like ka waiwai o DN me ka waiwai NPS i hoʻonui ʻia e 25.4 (mm/ʻīniha) e hoʻopuni i ka hopena.
I ka hoʻomaʻamaʻa ʻana, ʻoi aku ka nui o ka pilina ma waena o nā kūlana NPS a me DN ma luna o nā papa ʻaina maʻamau i hoʻokumu ʻia.
Mānoanoa Pā (WT)
ʻO ka mānoanoa o ka pā paipu.No ka paipu ma'amau, pili pinepine ka mānoanoa o ka pā me ka Hō'ike o ka paipu, no ka la'ana, ka Papa 40 a i 'ole ka Papa 80, kahi e hō'ike ai nā waiwai nui i nā pā mānoanoa.
Ka lōʻihi
ʻO ka lōʻihi o kahi paipu kila, hiki ke hoʻopaʻa ʻia a i ʻole ke koho, ma muli o ka hana a me nā koi noi.ʻO 6 mika a me 12 mika ka lōʻihi maʻamau.
Mea waiwai
Nā kūlana waiwai a me nā māka no ka paipu kila, e like me ASTM A106 Grade B, API 5L Grade B, a me nā mea ʻē aʻe. Hōʻike kēia mau kūlana i ka haku mele a me nā waiwai kino o ka paipu.
Nā kūlana
ʻO nā kūlana maʻamau no ke kalapona a me ka paipu kila kila ma muli o ka ASME B36.10M (carbon and alloy steel) a me B36.19M (stainless steel pipe).
Nā Papa Nui Paipu a me nā Papa Kaumaha (WGT)
hāʻawi i kahi ala maʻamau e wehewehe i ka mānoanoa o ka pā paipu ma lalo o nā Hōʻike like ʻole, a me ka hoʻokaʻawale ʻana o nā māka kaumaha e like me STD, XS, XXS, a me nā mea ʻē aʻe.
ʻO ka mānoanoa o ka pā o ka paipu pili pono i ka nui o loko a me ke kaumaha o ka paipu.He mea koʻikoʻi ka mānoanoa o ka pā no ka mea ʻo ia ka mea e hoʻoholo ai i ka nui o ke kaomi kūloko e hiki ai i ka paipu ke kū.
Helu hoʻonohonoho
ʻO kahi ala e hōʻike ai i ka mānoanoa o ka pā o ka paipu, e like me ka Hōʻike 40 a me 80, e pili ana i ka mānoanoa a hoʻoikaika ʻia o ka pā o ka paipu no kahi anawaena o waho.
ʻO ka helu ʻana o kahi helu hoʻonohonoho penei:
Ma muli o ko lākou hiki ke pale i nā pilikia maʻamau, ʻo ka Hōʻike 40 a me ka Hōʻike 80 mau paipu kila i makemake nui ʻia i nā ʻoihana like ʻole.No ka mea ua hoʻolālā ʻia kēia mau paipu e kū i nā kaomi kiʻekiʻe, koi pinepine lākou i nā mea nui e hoʻokō i nā pono o nā ʻoihana like ʻole.
