API 5L paipu kila hoʻolauna

API 5Lmaʻamau e pili ana i ka pipeline steel pipe (pipeline pipe) o ka hoʻokō ʻana i ka maʻamau, pipelinepaipu kilame ka paipu kila ʻole a me ka paipu kila welded ʻelua ʻano. I kēia manawa i loko o ka ʻaila pipeline mākou i hoʻohana maʻamau i ka welded steel pipe type spiral submerged arc welded pipe (SSAW), humuhumu pololei i hoʻopaʻa ʻia i loko o ke arc welded paipu (LSAW), paipu kuʻekuʻe kūʻē (ERW), paipu kila ʻolehoʻohana maʻamau i ka pipeline anawaena he emi ma mua o 152mm.

ʻO ka pae aupuni GB / T 9711-2011 paipu kila no ka pipeline transport system i loko o ka ʻoihana aila a me ke kinoea i hōʻuluʻulu ʻia e like me API 5L.

Hōʻike ʻo GB / T 9711-2011 i nā koi hana no nā paipu kila maʻemaʻe a welded o nā pae kikoʻī huahana ʻelua (PSL1 a me PSL2) no nā ʻōnaehana kaʻa pipeline i ka ʻoihana aila a me ke kinoea. No laila, pili wale ka maʻamau i nā paipu kila ʻole a me nā paipu kila welded no ka lawe ʻana i ka aila a me ke kinoea, ʻaʻole pili i nā paipu hao.

Papa kila

ʻO nā māka kila o nā mea maka no nā paipu kila o kēia maʻamau API 5L he GR.B, X42, X46, X52, X56, X60, X70, X80, a me nā mea'ē aʻe. a ʻokoʻa nō hoʻi ka hana ʻana, akā mālama pono ʻia nā mea like kalapona ma waena o nā pae kila like ʻole.

 

Nā kūlana maikaʻi

Ma ka API 5L paipu maʻamau, ua māhele ʻia nā kūlana maikaʻi (aiʻole nā ​​koi) no ka paipu kila i PSL1 a me PSL2. ʻO PSL kahi pōkole no ka pae kikoʻī huahana.

Hāʻawi ka PSL1 i kahi pae maʻamau o nā koi maikaʻi o ka paipu; Hoʻohui ʻo PSL2 i nā koi koi no ka hoʻohui ʻana i nā kemika, ka paʻakikī notched, nā waiwai ikaika, a me nā NDE hou.
