Ma ke ʻano he pipeline kaʻa koʻikoʻi, hoʻohana nui ʻia nā paipu kila seamless 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 ʻili, 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 nokiʻekiʻe-press boilers.
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 ka pale 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 ka ultrasonic, ray a me nā ʻano hana ʻē aʻe e hoʻāʻo ai i nā paipu kila e hōʻoia i ka maikaʻi ʻole o ka maikaʻi o loko o nā paipu kila ʻole.
