Pipa wiliwili ʻia ʻo Spiral Submerged Arc Welded In API 5L Line Pipe Applications Featured Image

ʻO ka wehewehe pōkole:

Ma ka ʻoihana kaʻa aila a me ke kinoea, ʻoi aku ka maʻamau o ka hoʻohana ʻana i nā paipu wili arc submerged arc, ʻoi aku ka nui o ke kūkulu ʻana i nā ʻōnaehana paipu laina API 5L.Ua ʻike ʻia ka paipu SSAW (submerged arc welded) no kona ikaika kiʻekiʻe, ka lōʻihi a me ka maʻalahi, i mea kūpono no nā noi noi e like me ka ʻoihana aila a me ka ʻenehana.

ʻO kaAPI 5L laina paipuʻO ka standard kahi kikoʻī i hoʻomohala ʻia e ka American Petroleum Institute (API) no ka lawe ʻana i ke kinoea maoli, ka aila a me ka wai.Hōʻike ia i nā koi hana no nā paipu kila welded a hoʻonohonoho i nā alakaʻi koʻikoʻi no ka maikaʻi, ikaika a me ka hana o kēia mau paipu.

paipu SSAWhana ʻia me ka hoʻohana ʻana i ke kaʻina hana kuʻi ʻana i loko o ke arc e pili ana i ka hana ʻana i kahi wili kila i ke ʻano poepoe a laila hoʻohana i kahi arc wili e hoʻohui i nā kihi o ka ʻōwili.

ʻO kekahi o nā pōmaikaʻi nui o ka hoʻohana ʻana i ka paipu welded arc submerged spiral i nā noi paipu laina API 5L ʻo ko lākou hiki ke kū i nā pae kiʻekiʻe o ke kaomi kūloko a me waho.He mea koʻikoʻi loa kēia i ka ʻoihana aila a me ke kinoea, kahi e hōʻike ʻia ai nā pipeline i nā kūlana koʻikoʻi a me nā ukana kaumaha.ʻO ke kūkulu ikaika ʻana o nā paipu SSAW he mea kūpono ia no nā pipeline e hana ana i nā kaomi kiʻekiʻe a me nā mahana, e hāʻawi ana i kahi hopena hilinaʻi a lōʻihi no ka lawe ʻana i nā kumuwaiwai waiwai.

Eia kekahi, ʻo ka maʻalahi o ka spiral submerged arc welded pipe e maʻalahi ka hoʻouka a mālama ʻana, e lilo ia i koho kūpono no nā papahana kūkulu pipeline.ʻO ko lākou hiki ke hoʻololi a hoʻohālikelike i nā ʻano kūlohelohe o ka ʻāina e hoʻopau i ka pono no ka hana maʻamau kūpono a me ka manawa e hoʻemi ai i ka hopena o ka leaks a me ka hemahema.Hoʻohui ʻia, ʻo ka ʻili o loko o nā paipu SSAW e hōʻemi i ka friction a me ka turbulence, e hopena i ka kahe ʻoi aku ka maikaʻi a me ka hoʻemi ʻana i ka ikehu.
