ʻO ka ʻoihana hao a me ke kila ʻo Ruigang ka wikiwiki i kona hoʻololi ʻana a me ka hoʻomohala ʻana i ke ʻano o ke kūlana kiʻekiʻe, ʻōmaʻomaʻo, naʻauao a hoʻohui pū ʻia, e hana ana i kahi ʻano hou o ka hoʻomohala ʻana i nā ʻoihana kākoʻo e like me ka hana kila, ka hana ʻana i nā mea hana, a me nā ʻāpana hana, alakaʻi ʻia e ka hao. a me nā ʻoihana hana kila.
I kekahi mau lā i hala aku nei, ua hana ʻia e ka mea kūʻai aku ka 1910mm hot-rolled coiled pipeline steel X52MS, ka mea ākea loa a mākou i kūʻai aku ai, a ua hōʻike mai ka mea kūʻai aku he maikaʻi loa ka huahana "kūʻai pālua" i ka haki ʻana i ka hydrogen-induced a me ka hydrogen sulfide. stress corrosion, hiki ke hoʻokō i nā koi o ka nui-diameter aila a me ke kinoea pipeline manufacturing.E hoʻohana ʻia ia no ke kūkulu ʻana i nā hana aila nui a me ke kinoea ma Saudi Arabia ma nā ʻāina ma ka "Belt and Road".
Hoʻohana nui ʻia ke kila pipeline "ʻelua-kū'ē" i ka hana ʻana i ka hoʻomaʻemaʻe ʻaila a me nā pipeline kemika e lawelawe ana i nā wahi paʻakikī ma muli o kona kūpaʻa maikaʻi loa.I kēia manawa, ke hoʻomau nei nā ʻoihana hoʻomaʻemaʻe ʻaila a me nā ʻoihana ʻaila a me nā kinoea i ke koi no ke kila pipeline "pālua-kū'ē", ʻoi aku ka nui o nā huahana kikoʻī ākea, a ākea loa ka mākeke.
