ʻO ka maʻamau o ka paipu kila maʻemaʻe kalapona

Paipu kila maʻemaʻe kalaponaʻO nā kūlana he mea koʻikoʻi i ka hōʻoia ʻana i ka maikaʻi, kūpono a me ka palekana o kēia mau paipu i nā ʻano noi.Hāʻawi kēia mau maʻamau i ke alakaʻi no nā mea hana, nā mea hoʻolako a me nā mea kūʻai aku e hōʻoia i ka hoʻokō ʻana o ka paipu i nā koi kikoʻī a hoʻokō i nā lula ʻoihana.

ʻO kekahi o nā kūlana i ʻike nui ʻia no ka paipu kila seamless carbon kaASTM A106/A106Mmaʻamau.Hoʻomohala ʻia e ka American Society for Testing and Materials (ASTM), ua kuhikuhi kēia maʻamau i nā koi no ka paipu kila carbon seamless no ka lawelawe wela kiʻekiʻe.Uhi ia i ka nui o ka paipu NPS 1/8 a hiki i ka NPS 48 (DN 6 a hiki i DN 1200) a me ka mānoanoa o ka paia e like me ka mea i kuhikuhi ʻia ma ANSI B36.10.

Ma waho aʻeo, carbon seamless kila paipu maʻamau komo API 5L,ASTM A53, ASTMA179,ASTM A192,ASTM A210/SA210, ASTM A252, BS EN10210,JIS G3454a me JIS G3456.

Hoʻohui ʻia, loaʻa ka maʻamau i nā koi no ka hoʻāʻo ʻole luku ʻole, e like me ka hoʻāʻo ultrasonic, eddy current testing a hydrostatic hoʻāʻo, e hōʻoia i ka pololei o ka pipeline.Hoʻopuka pū ia i nā ʻano like ʻole e pili ana i ka mākaʻikaʻi ʻana, ka ʻōpala a me nā koi hōʻoia.

I ka hōʻuluʻulu ʻana, hāʻawi nā kūlana paipu kila kila ʻole carbon, e like me ASTM A106/A106M, i nā alakaʻi kūpono no ka hana ʻana, hoʻāʻo, a me ka mana maikaʻi o kēia mau paipu.ʻO ka hoʻokō ʻana i kēia mau kūlana e hōʻoia i ka hoʻokō ʻana o nā pipeline i nā kikoʻī i koi ʻia, ka hana a me nā koi palekana, e hoʻonui ana i ko lākou hilinaʻi a kūpono i nā ʻano ʻoihana ākea.
