Ma nā kaʻina hana kemika, ʻona pinepine nā wai i loko o nā paipu, radioactive a weliweli.Hoʻopaʻa ʻia nā kīwaha honua i ka Bellowshoʻohana ʻia e pale i ka leaka ʻana o kekahi kemika ʻona i ka lewa.Hiki ke koho ʻia nā mea kino mai nā mea āpau i loaʻa, Hiki ke hāʻawi ʻia ka bellow i nā mea like ʻole e like me 316Ti, 321, C276 a i ʻole Alloy 625.

• 1) He nui nā mea hiki ke loaʻa ma keʻano maʻamau (streght pattern), Angle pattern, a me Wye pattern (Y pattern).
• 2). Hoʻopaʻa nā bellow metala i ke koʻokoʻo neʻe a hoʻonui i ka lōʻihi o nā pahu hoʻopaʻa sila.
• 3). Hoʻāʻo pinepine ʻia nā pahu i hoʻopaʻa ʻia ma lalo me ka hoʻohana ʻana i kahi spectrometer nui no ka ʻike ʻana i ka leakage ma lalo o 1x10E-06 std.cc/sec. leakage, a e like me nā kūlana paʻa honua;
• 4) .Easy Machining a me ka hoʻoulu houʻana o nā noho, no nā kumu likeʻole.
• 5) ..Short huakaʻi mamao o ka disc(stroke) ma waena o ka hamama a pani pani,Hoʻopaʻa ʻia nā kīwaha honua i ka Bellowskūpono inā pono e wehe a pani pinepine ʻia ka valve;
