Ma luna o kēia mau mea kumu maʻamau, hiki i nā mea hana ke hoʻohui i nā pale pale.ʻOi aku ka palekana o kēia mau hoʻopau ʻana i ka corrosion.Eia kekahi mau uhi maʻamau no nā wili hoʻopaʻa ponoʻī Countersunk:

Pāpala Zinc
ʻO ka Zinc Plating kahi i hoʻohui ʻia ai ka zinc me ka hoʻohana ʻana i kahi papa uila.ʻO ka maʻamau he ʻāpana lahilahi i ʻoi aku ka maikaʻi no nā noi i loko.

ʻO ka Galvanization wela
Hoʻohui ka galvanization wela i ka zinc, akā he uhi hohonu.Hoʻokomo nā mea hana i ka pahu i loko o ka zinc hoʻoheheʻe ʻia e hana i kahi paʻa, kahi e kūpono ai ka uhi no nā wahi ʻino e like me nā wahi me ka haʻahaʻa kiʻekiʻe a i ʻole ka paʻakai i ka lewa.

ʻO Fluoropolymer (Xylan, Teflon, a i ʻole PTFE) ka uhi
ʻO ka uhi fluoropolymer kahi hui ʻana o nā mea i kū i ka corrosion.Hiki ke hoʻopaʻa ʻia ka uhi ʻana i nā mahana wela a me ke anuanu ʻole me ka haki ʻole.

ʻAi Thermoplastic
ʻO ka pōmaikaʻi mua o ka hoʻohui ʻana i kahi uhi thermoplastic i nā U-bolts ka mea hoʻohui i hoʻohui ʻia ma waena o nā metala.Hiki i ka pilina metala ke alakaʻi i ka ʻino galvanic a me nā hale haki.Hoʻohui ka uhi thermoplastic i kahi ʻāpana pale pale ma waena o ka paipu a me ke kaohi.
He haʻahaʻa haʻahaʻa ko ka uhi ʻana o ka friction, ʻo ia ka mea e ʻae ai i ka paipu e holo ma ka U-bolt, ʻoiai e hoʻomoe ana i ka paipu i ka manawa like.Hoʻemi kēia i ka pilikia o nā paipu haʻihaʻi, kaohi, a i ʻole nā ​​hale kākoʻo.
