ʻO ka pahu puka puka Bolt Bonnet
1. Hoʻokō pono ʻia ka hoʻolālā a me ka hana ʻana ma muli o GB / T 12234, API600 a me API602. Hōʻike nā huahana i kahi hoʻolālā kūpono, sila hilinaʻi, hana maikaʻi a me ka hoʻohālike maikaʻi.
2. Co paakiki wiliwili sealing ili, ka mea i komo ku e, erosion hōʻoia, abrasion a me ka lōʻihi-ola.
3. ʻO ka ʻili a me ka media hoʻoponopono ʻana o ka pahu valve i hoʻopaʻa ʻia i mea e pale ai i ka erosion a me ka abrasion.
4. PN≥15.0MPa (Class 900), hoʻohana ka lua waena i kahi ʻano hoʻopaʻa hoʻopaʻa paʻa ponoʻī e hoʻoikaika i ka hana sealing me ka piʻi ʻana o ke kaomi i mea e hōʻoia ai i ka hana sealing.
5. ʻAʻohe mea hoʻopaʻa hoʻopaʻa hope i ka valve, no laila ke hilinaʻi nei ka sealing id.
6. Hiki ke koho a hoʻohālikelike i nā mea o ka hoʻopiha a me ka nui o ka flange e like me nā noi a me nā koi o ka hoʻohana ʻana. Hiki iā ia ke hoʻokō i nā ʻano hana a pau.
