ʻO nā paipu lauwili ʻole he mau paipu me ka ʻole o nā humu a i ʻole nā ​​wili. Manaʻo ʻia nā paipu kila seamless e hiki ke kū i nā kaomi kiʻekiʻe, ke kiʻekiʻe kiʻekiʻe, ke koʻikoʻi mechanical kiʻekiʻe a me nā ea corrosive.

1. Hana ʻia

Hana ʻia nā paipu kila seamless me ka hoʻohana ʻana i nā ʻano hana like ʻole. ʻO ke ʻano i hoʻohana ʻia ma muli o ke anawaena i makemake ʻia, a i ʻole ka ratio o ke anawaena i ka mānoanoa o ka paia, pono no ka noi i makemake ʻia.

ʻO ka maʻamau, hana ʻia nā paipu kila maʻemaʻe e ka hoʻolei mua ʻana i ke kila maka i kahi ʻano hana ʻoi aku ka hana-he billet paʻa wela. A laila "hohola" a huki ʻia a huki ʻia ma luna o ka make. ʻO kēia ka hopena i nā paipu hollow. A laila "hoʻokuʻu ʻia" ka paipu hollow a koi ʻia ma o ka make a me ka mandrel e loaʻa ai nā anawaena pā i loko a me waho.

I mea e hōʻoia ai i ka hoʻokō ʻana o ka paipu kila seamless i kekahi mau kūlana, pono ia e kau ʻia i ka mālama wela kūikawā e hōʻoia i ka hoʻokō ʻana o kāna mau metallurgical i nā koi e pono ai. Ke koi ʻia, loaʻa nā mea paipu kūikawā mai nā paipu duplex a me super duplex seamless mai nā mea hana i ʻae ʻia e NORSOK M650. Mālama kēia i ka maikaʻi kiʻekiʻe loa a me ka lōʻihi no kā mākou mea kūʻai.

2. Noi

Hiki ke loaʻa nā paipu kila maʻemaʻe ʻole a no laila hiki ke loaʻa ma kahi ākea o nā māla. Hoʻopili kēia i ka aila a me ke kinoea, refinery, petrochemical, chemical, fertilizer, power and automotive industry.
Hoʻohana mau ʻia ka paipu kila seamless e lawe i nā wai e like me ka wai, ke kinoea maoli, ka ʻōpala a me ka ea. Pono pinepine ia i loko o ka nui o ke kaomi kiʻekiʻe, nā kaiapuni corrosive loa a me ke kaiapuni, ka mechanical a me ka hoʻolālā.

3. Pono
Ka ikaika: ʻAʻohe seamless paipu kila ʻole. 'O ia ho'i, ua ho'opau 'ia ka hiki 'ana o nā hili "nawaliwali", no laila, hiki i ka paipu kila ma'amau ke pale aku i ka 20% ki'eki'e o ka hana 'ana ma mua o ka paipu welded o ka mea like a me ka nui. ʻO ka ikaika paha ka pōmaikaʻi nui loa o ka hoʻohana ʻana i ka paipu kila ʻole.
Kū'ē: ʻO ka hiki ke pale aku i ke kū'ē kiʻekiʻe he pōmaikaʻi ʻē aʻe o ka maʻemaʻe. ʻO kēia no ka mea ʻaʻole i loaʻa nā hili ʻana, ʻo ia hoʻi, ʻoi aku ka liʻiliʻi o nā haumia a me nā hemahema ke ʻike ʻia ma ke ʻano maʻamau ma ka weld.

ʻO ka hoʻāʻo liʻiliʻi: ʻO ka loaʻa ʻole o nā welds ʻo ia ka mea ʻaʻole pono ka paipu kila maʻemaʻe e hana i ka hoʻāʻo kūpaʻa ikaika like me ka paipu welded. ʻO ka hana liʻiliʻi: ʻAʻole pono kekahi mau paipu kila maʻemaʻe i ka wela ma hope o ka hana ʻana no ka mea ua paʻakikī lākou i ka wā e hana ai.
