ʻO AWWA C207 kahi maʻamau i hoʻomohala ʻia e ka American Water Association e hoʻoponopono i ka hoʻolālā, hana, hoʻāʻo, a me ka hoʻohana ʻana i nā flanges welded neck. Hoʻohana pinepine ʻia nā flanges welded neck i nā ʻōnaehana pipeline e hoʻopili ai i nā paipu o nā ʻano nui a i ʻole nā ​​​​mea waiwai, a me ka hoʻopili ʻana i nā kiwi, pamu, a me nā mea hana ʻē aʻe.

ʻO ka maʻamau AWWA C207 ka wehewehe ʻana i nā ʻano like ʻole o ka ʻāʻī welded flanges, me nā kikoʻī o nā nui like ʻole, nā helu kaomi, a me nā diameters nominal, e hoʻokō i nā pono o nā ʻōnaehana pipeline. Eia nā ʻōlelo kikoʻī maʻamau i kēia maʻamau:

Nā ana:

Aia ka maʻamau AWWA C207 i nā ʻāpana metric a imperial, me nā ana metric me DN (DN15 a DN6000) a me nā ana imperial me NPS (1/2 "a 144").

Ka helu kaomi:

Hōʻike ka maʻamau AWWA C207 i nā helu kaomi he nui, me ka Papa D (175 psi), Papa E (275 psi), Papa F (300 psi), Papa G (300 psi), Papa H (300 psi), Papa J (300 psi ), etc.

Anawaena inoa:

Hōʻike ka maʻamau AWWA C207 i nā kikoʻī no nā anawaena inoa like ʻole, me DN 15 a DN 6000, NPS 1/2 "a 144", etc.

ʻO ka ʻāʻī ma luna o ka welding flange kahi mea hoʻopili pipeline maʻamau, kūpono no ka hoʻopili ʻana i nā paipu, nā ʻūhā, nā pamu, a me nā mea hana ʻē aʻe o nā mea like ʻole a i ʻole ka nui.

ʻO ka paheʻe ma luna o ka flangeʻO ka mea maʻamau he ʻelua mau papa flange pālahalaha, kahi ʻāʻī e hoʻopili ana i ʻelua mau papa flange, bolts, a me nā gaskets. ʻAʻole like me ka ʻāʻī welded flange, pono ka hoʻohana ʻana i nā bolts a me nā gaskets no ka hoʻopaʻa ʻana, ʻaʻole ma o ka wili ʻana.

Hōʻike ka maʻamau ʻo AWWA C207 i nā ʻano like ʻole o ka ʻāʻī wiliwili palahalaha, me ka nui metric a me ka imperial, nā helu kaomi ʻokoʻa, a me nā māka waiwai. No ka laʻana, ua hōʻike ka maʻamau i ʻeono mau pae kaomi: Papa D, Papa E, Papa F, Papa G, Papa H, a me Papa J. Ma waena o lākou, ʻo ka Papa D ka pae haʻahaʻa haʻahaʻa kūpono no nā haʻahaʻa hana haʻahaʻa, ʻoiai ʻo Class J ka kiʻekiʻe kiʻekiʻe puʻe kūpono kūpono no ke kiʻekiʻe hana puʻe.

Eia kekahi, hōʻike pū ka maʻamau AWWA C207 i ka hana ʻana, ka mana maikaʻi, a me nā koi hoʻāʻoʻāʻī welded flangese hōʻoia i ka hoʻokō ʻana o nā flanges welded neck i nā koi maʻamau. I ka hoʻohana 'ana i ka'ā'ī welded flanges, he mea pono e hōʻoia i ka mea a me ke kaomi pae o kapā flange a me ka ʻāʻīua like ia, a e hoʻouka a hoʻāʻo e like me nā koi maʻamau e hōʻoia i ka palekana a me ka hilinaʻi o ka ʻōnaehana. Hoʻohana pinepine ʻia nā flanges welding ʻāʻī ʻāʻī i nā ʻōnaehana haʻahaʻa haʻahaʻa, haʻahaʻa haʻahaʻa, a i ʻole nā ​​​​mea hoʻoheheʻe haʻahaʻa, e like me ka hāʻawi wai, ventilation, air conditioning, a me nā māla ʻē aʻe.
