He paipu kila maʻamau API5L GRB i hoʻohana nui ʻia, hoʻohana nui ʻia i ka ʻaila, kinoea a me nā ʻoihana ʻē aʻe. ʻO kāna "API5L" kahi maʻamau i hoʻomohala ʻia e ka American Petroleum Institute, a ʻo "GRB" e hōʻike i ke ʻano a me ke ʻano o ka mea, i hoʻohana mau ʻia no nā paipu kaomi. ʻO ka maikaʻi o nā paipu kila maʻemaʻe e pili ana i ko lākou mau ʻano mechanical maikaʻi loa a me ka pale ʻana i ka corrosion, a hiki iā lākou ke hana paʻa i nā wahi paʻakikī me ka wela kiʻekiʻe a me ke kaomi kiʻekiʻe.

ʻO nā mea kemika nui o API5L GRB mau paipu kila ʻole he kalapona, manganese, sulfur, phosphorus, etc., a loaʻa iā lākou ka weldability a me ka plasticity ma hope o ke kaʻina hana wela. Hoʻohana pinepine ʻia kēia ʻano paipu kila no ka lawe ʻana i nā wai a me nā kinoea, ʻoi loa i ka hoʻohana ʻana a me ka lawe ʻana i nā māla aila a me ke kinoea, e hōʻoia i ka palekana a me ka pono.

ASTM A53, ASTM A106aAPI 5Lʻekolu mau paipu kila maʻamau maʻamau, kūpono kēlā me kēia no nā hiʻohiʻona noiʻi like ʻole.

Hoʻohana nui ʻia ka maʻamau ASTM A53 i nā kula e like me ka mana, kūkulu a me nā petrochemical. ʻO ka paipu kila o kēia maʻamau he kūpono ia no ka haʻahaʻa haʻahaʻa a me nā haʻahaʻa haʻahaʻa haʻahaʻa, a hoʻohana mau ʻia e lawe i ka wai, ke kinoea a me nā wai ʻē aʻe. Loaʻa iā ia ka ikaika a me ka weldability, a kūpono no ka hana ʻana i nā pipelines a me nā ʻāpana kūkulu.

ʻO ka maʻamau ASTM A106 e kālele nui ana i nā noi wela kiʻekiʻe a me ke kaomi kiʻekiʻe a kūpono ia no ka ʻoihana ʻaila a me ka ʻea. Hoʻohana nui ʻia nā paipu kila seamless o kēia maʻamau no ka lawe ʻana i ka mahu, ka wai wela a me ka ʻaila. Hiki iā lākou ke mālama i nā waiwai mechanical maikaʻi i nā mahana kiʻekiʻe e hōʻoia i ka palekana a me ka paʻa o ka pipeline.

Hoʻolālā ʻia ka maʻamau API 5L no ka ʻoihana ʻaila a me ke kinoea a kūpono no nā pipeline hoʻouna kiʻekiʻe. ʻO nā paipu kila maʻemaʻe e kū nei i kēia maʻamau he kūpaʻa maikaʻi loa i ka corrosion a me ke kūpaʻa kaomi, e hōʻoiaʻiʻo ana i ka hana palekana ma lalo o nā kūlana koʻikoʻi. Hoʻohana pinepine ʻia nā pipeline API 5L i ka hoʻohana ʻana a me ka lawe ʻana i nā māla aila a me nā kinoea e hōʻoia i ka lawe ʻana i nā wai.

ʻO kēia mau kūlanaʻekolu o nā paipu kila maʻemaʻeʻole ko lākou mauʻano pono'ī, e uhi ana i nā hiʻohiʻona noiʻi likeʻole mai ka haʻahaʻa haʻahaʻa a hiki i ke kiʻekiʻe kiʻekiʻe, mai ka haʻahaʻa haʻahaʻa a hiki i ke kiʻekiʻe kiʻekiʻe, e hālāwai me nā ponoʻoihana likeʻole, a me ka hāʻawiʻana i nā hōʻoia no ka palekana a me ka pono.
