ʻO ka ductile iron wide tolerance stepped coupling he ʻano hoʻohui i hoʻohana ʻia no ka hoʻopili ʻana i ʻelua paipu a i ʻole nā mea pono o nā nui like ʻole.Hana ʻia ia me ka hao ductile, ʻo ia ke ʻano o ka hao i ʻoi aku ka maʻalahi a me ka lōʻihi ma mua o ka hao hoʻolei kuʻuna.
ʻO ka hoʻolālā hoʻomanawanui ākea o ka hui ʻana e hiki ai ke hoʻopili ʻia ka nui o ka nui o nā paipu, e hōʻemi ana i ka pono o nā hui a me nā mea pono.Hāʻawi ka hoʻolālā ʻanuʻu o ka hui ʻana i kahi paʻa paʻa a paʻa i waena o nā paipu, e hōʻoia ana i kahi pilina leak-leak.
Hoʻohana maʻamau ʻia nā mea hoʻohui i ka wai a me nā mea kanu hoʻomaʻemaʻe wai, a me nā noi ʻoihana e like me ka ʻaila a me nā paipu kinoea.Hoʻohana pū ʻia lākou i nā ʻōnaehana plumbing a me HVAC e hoʻopili ai i nā paipu o nā ʻano like ʻole.
ʻO ka holoʻokoʻa, ʻo ka ductile iron wide tolerance stepped couplings he hopena hilinaʻi a maikaʻi hoʻi no ka hoʻopili ʻana i nā paipu o nā ʻano nui like ʻole, e hāʻawi ana i kahi pilina paʻa a leak-leak hiki ke kū i nā koi o nā noi like ʻole.

• Kūlike i nā kūlana:
- NF A 48-830: Nā huahana hana - Spheroïdal graphite i hao
nā mea pono no nā paipu wai inu PVC ma lalo o ke kaomi.
- NF EN 545: ʻO nā paipu hao ductile, nā mea pono, nā mea pono a me ko lākou mau hui no
nā paipu wai - nā koi a me nā ʻano hoʻāʻo.
- ISO 2531: ʻO nā paipu hao ductile, nā mea pono, nā mea hoʻohui a me ko lākou mau hui
nā noi wai.
• 'Apono 'ia:
- Ua ʻae ʻia ka wai inu.
• Nota:
ʻAʻole kūʻē kēia hui ʻana i nā ikaika longitudinal a maopopo
hāʻawi ʻia kahi kaohi kūpono e pale ai i ka wehe ʻana o nā paipu.
