Snā hui hoʻokaʻawale i kāohi ʻia e ka elf

1. Hoʻohana ʻia e hoʻomaʻalahi i ka wehe ʻana a i ʻole ka hoʻākoakoa hou ʻana o kahi ʻāpana lako flanged ma kahi pipeline, a hiki ke hoʻololi ʻia ka lōʻihi me ka hele nui ʻana.

2. E hoʻomaʻalahi i nā hana mālama no ka mea ua hoʻopaʻa ponoʻī ʻia ka pilina a ʻaʻohe pono no nā poloka heleuma sima.

Hoʻokaʻawale ʻana i ka hui no ka kiwikā pepeke flanged

1. Hoʻomaʻalahi i ka wehe ʻana a me ka hoʻākoakoa hou ʻana ma kahi ma ka pipeline ke hoʻopaʻa ʻia i kahi valve flanged me ka hōʻoia ʻana i ka hoʻomau ʻana o ke kūʻē mechanical.

2. ʻO ka holo hiki ke hoʻololi ʻia o kēia mau huahana ʻo ia hoʻi, ʻaʻole ia he mea hopohopo hou ka ʻae ʻana "maka a maka" o nā lako e hoʻokomo ʻia.

3. Hana i ke kau ʻana i nā apo hui ma waena o nā flanges maʻalahi, ʻoiai nā mea me nā mea hoʻokomo 4. Loaʻa mai DN 40 a i DN 2000, me nā PFA o 10, 16 a me 25 bar

Ke wehe ʻana i ka hui no ka valve butterfly me ka ʻole o nā flanges

1. Ka huakaʻi hoʻololi kiʻekiʻe loa o 50 mm ke hoʻopaʻa ʻia i nā kiwikā pepeke me ka ʻole o nā flanges.

2. Loaʻa mai DN 40 a i DN 1200, me nā PFA o 10 a me 16 bar.
