Paipu Laina SSAW X65 Superior: He Hoʻonā Kiʻekiʻe no ka ʻOihana Paipu Kūpono a Hilinaʻi

Wehewehe Pōkole:

Kuhi kēia ʻāpana o kēia Kūlana ʻEulopa i nā kūlana hoʻouna loea no nā ʻāpana kūkulu i hoʻopaʻa ʻia i ke anu, nā ʻāpana hakahaka o nā ʻano poepoe, huinahā a ʻehā paha a pili i nā ʻāpana hakahaka kūkulu i hana ʻia i ke anu me ka ʻole o ka mālama wela ma hope.

Hoʻolako ʻo Cangzhou Spiral Steel Pipes Group Co., Ltd i nā paipu kila ʻāpana hakahaka o nā ʻano poepoe no ke kūkulu ʻana.

He aha ka paipu laina welded spiral submerged arc X65?

ʻO ka paipu laina X65 SSAW (submerged arc welded) kahi ʻano paipu kila i hoʻohana nui ʻia mapaipuke kūkulu ʻana ma ka ʻoihana aila a me ke kinoea. ʻO ka hui pū ʻana o ka ikaika, ke kūpaʻa a me ka hana kupaianaha o kēia paipu laina ua lilo ia i koho mua no nā papahana like ʻole a puni ka honua.

Ikaika a me ke kūpaʻa:

ʻO kekahi o nā hiʻohiʻona koʻikoʻi e hoʻokaʻawale ai i ka paipu laina welded arc spiral submerged X65 ʻo ia kona ikaika a me ke kūpaʻa. Hana ʻia me ke kila kiʻekiʻe, he kūpaʻa ikaika kona i ke kaomi kūloko a me waho. ʻO kēia ka mea e koho maikaʻi loa ai no nā noi aila a me ke kinoea koi, e hōʻoiaʻiʻo ana he hilinaʻi a lōʻihi ke ʻano o ke kahua.

Ka pono o ka hana ʻana o ka paipu:

He mea koʻikoʻi ka pono i ka lawe ʻana i nā kumuwaiwai ma o nā paipu. ʻOi aku ka maikaʻi o ka paipu laina X65 SSAW ma kēia wahi, e hāʻawi ana i ke kahe mālie me ka liʻiliʻi o ka friction, a laila e hōʻemi ana i ka hoʻohana ʻana i ka ikehu i ka wā o ka lawe ʻana. Kōkua kēia pono i ka mālama ʻana i nā kumukūʻai a me ka hōʻemi ʻana i ka hopena o ke kaiapuni, e lilo ia i koho aloha i ke kaiapuni.

Kūpaʻa i nā ʻano ʻino:

Ke hele nei nā pūnaewele paipu i nā ʻano kaiapuni like ʻole, me nā kaiapuni ʻino a me nā ʻino. Ua hōʻoia ka paipu laina welded arc spiral submerged X65 i kona ʻoi aku ka maikaʻi ma ia mau kūlana ma muli o kona kūpaʻa maikaʻi loa i ka pala, ka abrasion a me nā mea o waho ʻē aʻe. Hōʻoia kēia kūpaʻa i ka pono o ka ʻōnaehana paipu, hoʻemi i nā kumukūʻai mālama, a hoʻemi i ka pilikia o nā leaka a i ʻole nā hemahema.

ASD:

He mea koʻikoʻi ka mālama ʻana i nā hana paipu palekana. Hoʻoikaika ka paipu laina X65 SSAW i ka palekana ma o ka hāʻawi ʻana i nā waiwai mechanical maikaʻi loa a me ka pololei o ke ana. Ma o nā hana kaohi maikaʻi, mālama ka paipu i ke kūpaʻa o ke ʻano e pono ai e kū i nā kaomi kiʻekiʻe a me nā kūlana hana paʻakikī, e hōʻoiaʻiʻo ana i ka palekana o nā limahana a me nā kumuwaiwai.

I ka hopena:

ʻO ka paipu laina X65 SSAW kahi hopena maikaʻi loa i ke kūkulu ʻana a me ka mālama ʻana i nā ʻōnaehana paipu. ʻO kona ikaika, ka lōʻihi, ka pono a me ke kūʻē ʻana i nā ʻano ʻino e lilo ia i koho maikaʻi loa no ka ʻoihana aila a me ke kinoea a me nā ʻoihana ʻē aʻe e hilinaʻi nei i ka lawe ʻana i nā kumuwaiwai. Hāʻawi ka paipu laina X65 SSAW i ka mālama kālā, ke kūpaʻa o ke kaiapuni a me ka hōʻoia palekana, e lilo ia i waiwai nui no nā hana paipu e ʻimi nei i ka hilinaʻi a me ka pono.

No laila, inā ʻoe e hoʻomaka ana i kahi papahana paipu, ʻo ka noʻonoʻo ʻana i ka paipu laina X65 SSAW he koho naʻauao ia e hōʻoiaʻiʻo ana i ka hana maikaʻi loa a me ka holomua lōʻihi. E hoʻopukapuka i kēia hopena kiʻekiʻe a ʻike i ka hopena hoʻololi hiki iā ia ke loaʻa ma kāu ʻōnaehana paipu.

Ma mua: ʻO ka paipu kila wiliwili no ka ikaika a me ka pono kūlike ʻole ASTM A252
