Ke hoʻopilikia nei ka mānoanoa a me ka mea o ka papa insulation i ka pololei o ke ana ʻana ke hoʻokomo ʻia kahi mika kahe ultrasonic clamp-on ma kahi pipeline insulated? Pono anei nā hana kūikawā?

He hopena ʻaʻole pololei kona, akā ʻo nā pilikia nui ʻaʻole ia ka papa insulation ponoʻī, akā ʻo nā hakahaka ea ma waena o ka papa insulation a me ka paia o waho o ka pipeline, a me ka hopena hoʻopili.

• Inā pili pono ka papa insulation (e laʻa me ka huluhulu pōhaku, polyurethane) i ka paia o waho o ka pipeline a he ≤ 50mm ka mānoanoa, he liʻiliʻi kona hopena ma ka ultrasonic attenuation (me ka hewa maʻamau < 0.3%).
• Inā ʻelemakule ka papa insulation a hana i nā hakahaka ea kūloko (he ikaika loa ka attenuation o ka ea ma nā nalu ultrasonic), a inā paha > 100mm ka mānoanoa, e hāʻule koke ka ikaika o ka hōʻailona, ​​a hiki ke hoʻonui ʻia ka hewa pololei i ʻoi aku ma mua o ±5%.

Nā ʻAno Lapaʻau:

1. ʻO ke ʻano hana i makemake ʻia (inā hiki ke wehe ʻia ka insulation): E wehe i ka papa insulation ma kahi e hoʻokomo ai (pono e ʻoi aku ka nui o ka ʻāpana i wehe ʻia ma mua o ke kumu sensor), e hoʻomaʻemaʻe i ka ʻōpala a me nā ʻaila mai ka paia waho o ka pipeline, a laila e hoʻohana i kahi mea hoʻopili kūikawā (ma kahi o ka pata maʻamau) e hoʻopaʻa pono i ka sensor i ka paia waho o ka pipeline.
2. ʻAno hana ʻē aʻe (ke hiki ʻole ke wehe ʻia ka insulation): E koho i kahi sensor kūpono i ka mahana kiʻekiʻe a hoʻohālikelike iā ia me kahi probe i hoʻonui ʻia (ʻoi aku ka lōʻihi o ka probe ma mua o ka mānoanoa o ka papa insulation) e hana pololei i ka hoʻopili ʻana me ka paia o waho o ka pipeline.
