API 5L Grade B Carbon Steel Paipu Laina Paipu

ʻO ka wehewehe pōkole:

ʻO API 5L Grade B paipu kila he paipu maʻamau no ka lawe ʻana i ka ʻaila a me ke kinoea.ʻIke ʻia ʻo ia ʻo L245 paipu, i kuhikuhi ʻia i ISO 3183, i kapa ʻia ma hope o ka ikaika haʻahaʻa haʻahaʻa o 245 Mpa (355,000 Psi).

Mea like ʻo ASTM A106 B a i ʻole ASTM A53 B me ka waiwai like i ka haku melemele, nā waiwai mechanical a me ka noi.

Hoʻopili ʻo API 5L B i ka PSL1, PSL2, lawelawe ʻawaʻawa no nā paipu ma uka a me waho.Loaʻa nā ʻano hana i ka seamless a welded.

E hoʻouna i ka leka uila iā mākou

Hoʻolauna Huahana

PSL1, PSL2 a me nā ʻano Media Acid.

Hoʻohana maʻamau ka PSL1, ʻo ia ka mea like me ASTM A106 B a me A53 B.

ʻO PSL2 kahi paipu kikoʻī kiʻekiʻe me nā koi koʻikoʻi no ka ikaika kemika a me ka mechanical.Pono ʻo PSL2 i nā ʻano hoʻāʻo hou aʻe e like me ka hoʻāʻo ʻole luku ʻana, ka hoʻāʻo hopena CVN, DWT, etc.

Hōʻike ʻia ka API 5L B PSL2 e API 5L BN/Q/R/M.

Acidic medium: No nā pipeline acid e like me ka H2S environment, ʻo ka pipeline material nā koi maʻamau no nā mea kemika e like me carbon, phosphorus a me sulfur.Hōʻike maʻamau NACE MR0175.

Palapala Suffix

Hōʻike nā leka suffix i nā kūlana hoʻouna pipeline:

R: Ke kaa ana.

N: hana maʻamau, hana maʻamau, hana maʻamau.

Nīnau: Hoʻohaunaele a hoʻopau.

M: ʻO ka ʻōwili wela a i ʻole ka hana ʻana i ka thermomechanical.

S: Mea ʻawaʻawa me ka paipu PSL2 no NS, QS, MS, e laʻa me API 5L Grade B NS, API 5L B QS.

ʻO nā ʻano like ʻole a welded (RW, LSAW, SSAW/HSAW).

ʻAno Huahana

ʻAno laulima ʻole:me nā paipu wili wela ma luna o 3 ʻīniha, nā paipu liʻiliʻi liʻiliʻi ma lalo o 3 iniha.

ʻAno welding ERW:Kū'ē Kū'ē, kūpono no nā paipu a hiki i 24 iniha.

Ke ʻano kuʻi kuʻekuʻe wāwae i loko o ke kuʻi pololei:ʻO ka welding arc segmental longitudinal, kūpono i nā paipu me ke anawaena o waho o 20 iniha a 48 iniha.ʻIke ʻia ʻo LSAW ʻo JCOE, ʻo ia hoʻi ka hana ʻana i nā kiʻi mai ke ʻano J, ʻano C, ʻano O, a laila hoʻonui i ke anu.

ʻAno SSAW/HSAW:Spiral Submerged Arc Welding a i ʻole Spiral Saw no ka paipu a hiki i 100" OD.

API 5L Grade B, ASTM A106 Grade B a me A53 Grade B, ʻo kēia mau mea ʻekolu ka mea maʻamau i hoʻohana ʻia i ka hana pipeline a i ʻole ka aila a me ke kinoea a me nā ʻoihana lawe wai.

ʻO ka ASTM 106 Pipe e pili ana i ka paipu kalapona i ʻōwili ʻia a i ʻole ke anu (rolled) seamless carbon steel pipe.

ʻO ka paipu ASTM A53 e pili ana i nā paipu kila i hoʻopaʻa ʻia a me ka ʻole o nā mea ʻeleʻele kalapona, a ma kekahi mau mea i hoʻopaʻa ʻia i ka wela wela (galvanized).
