Ma ke ʻano he pipeline halihali koʻikoʻi, hoʻohana nui ʻia nā paipu kila ʻole i ka ʻaila, ke kinoea maoli, ka ʻoihana kemika, ka mana uila a me nā ʻoihana ʻē aʻe. I ka wā o ka hoʻohana ʻana, pono lākou e hoʻāʻo pono e hōʻoia i ka maikaʻi a me ka palekana o ka pipeline. E hoʻolauna kēia ʻatikala i ka hoʻāʻo ʻana o ka paipu kila maʻemaʻe mai ʻelua ʻano: nā mea hoʻāʻo a me nā ʻano hana.
ʻO nā mea hoʻāʻo e pili ana i ke ʻano, ka nui, ka maikaʻi o ka ʻili, ka haku mele, tensile, hopena, flattening, flaring, bending, hydraulic pressure, galvanized layer, etc.
ʻAno ʻike
1. Ho'āʻo tensile
2. Ho'āʻo hopena
3. Ho'āʻo palahalaha
4. Ho'āʻo hoʻonui
5. Ho'āʻo kūlou
6. Ho'āʻo hydraulic
7. Nānā papa galvanized
8. Pono ka maikaʻi o ka ʻili i ʻike ʻole ʻia nā māwae, nā pelu, nā ʻōpala, nā ʻoki a me ka delamination ma ka ʻaoʻao o loko a me waho o ka paipu kila.
Eia kekahi, e hoʻokō ʻia nā nānā e like me nā pono o ka mea kūʻai aku, e like meGB/T 5310-2017nā paipu kila ʻole nonā paila kiʻekiʻe.
ʻO ka haku mele: ʻO ke kila ka nui o nā mea e like me ka chromium, molybdenum, cobalt, titanium, a me ka aluminika, hiki ke hoʻomaikaʻi i ke kūpaʻa wela a me ka pale ʻana o ke kila.
Mechanical waiwai: hua ikaika ≥ 415MPa, tensile ikaika ≥ 520MPa, elongation ≥ 20%.
Nānā hiʻohiʻona: ʻAʻohe hewa i ʻike ʻia, wrinkles, pelu, māwae, ʻōpala a i ʻole nā pilikia maikaʻi ʻē aʻe ma ka ʻili.
ʻO ka hoʻāʻo ʻole luku: E hoʻohana i ke kani ultrasonic, ray a me nā ʻano hana ʻē aʻe e hoʻāʻo ai i nā paipu kila e hōʻoia i ka maikaʻi o loko o nā paipu kila maʻemaʻe ʻole.
