API 5L Qib B Carbon Steel Yeeb Nkab Kab Yeeb

Lus piav qhia luv luv:

API 5L Qib B steel yeeb nkab yog cov yeeb nkab zoo sib xws rau kev thauj mus los ntawm cov roj thiab cov kav dej.Nws tseem hu ua L245 yeeb nkab, hais txog ISO 3183, muaj npe tom qab lub zog qis kawg nkaus ntawm 245 Mpa (355,000 Psi).

Cov khoom sib npaug ASTM A106 B lossis ASTM A53 B nrog tus nqi zoo sib xws hauv cov tshuaj muaj pes tsawg leeg, cov khoom siv kho tshuab thiab daim ntawv thov.

API 5L B npog PSL1, PSL2, qaub kev pab cuam rau onshore thiab offshore pipelines.Fabrication hom muaj xws li seamless thiab welded.

Khoom Taw Qhia

PSL1, PSL2 thiab Acidic Media Hom.

Feem ntau siv PSL1, uas yog sib npaug rau ASTM A106 B thiab A53 B.

PSL2 yog cov yeeb nkab qib siab dua nrog cov kev cai nruj dua rau cov tshuaj lom neeg thiab lub zog.PSL2 xav tau ntau txoj kev sim xws li kev sim tsis muaj kev puas tsuaj, CVN cuam tshuam kev sim, DWT, thiab lwm yam.

API 5L B PSL2 yog sawv cev los ntawm API 5L BN/Q/R/M.

Acidic nruab nrab: Rau cov kav dej acid xws li H2S ib puag ncig, cov khoom siv hauv cov kav dej muaj cov kev cai rau cov tshuaj xws li carbon, phosphorus thiab sulfur.Kev siv tus qauv NACE MR0175.

Tsab ntawv Suffix

Suffix Letters qhia txog kev xa cov raj xa dej:

R: Thaum dov.

N: normalizing dov, normalizing txoj kev, normalizing.

Q: Tempering thiab quenching.

M: Thermomechanical dov lossis thermomechanical txoj kev.

S: Sour nruab nrab nrog PSL2 tubing rau NS, QS, MS, xws li API 5L Qib B NS, API 5L B QS.

Seamless thiab welded (ERW, LSAW, SSAW / HSAW) hom.

Yam khoom

Seamless Hom:suav nrog cov kav dej kub dov seamless tshaj 3 ntiv tes, txias-dov seamless kav hauv qab 3 ntiv tes.

ERW Vuam hom:Resistance Welding, haum rau cov kav dej mus txog 24 ntiv tes.

Ncaj Seam Submerged Arc Vuam Hom:Longitudinal segmented arc vuam, haum rau cov kav dej nrog ib txoj kab uas hla ntawm 20 ntiv mus rau 48 ntiv tes.LSAW tseem hu ua JCOE, uas txhais tau tias ua cov duab los ntawm J-shaped, C-shaped, O-shaped, thiab tom qab ntawd txias-ntws cov kav dej.

SSAW / HSAW Hom:Kauv Submerged Arc Vuam lossis Kauv Pom rau cov yeeb nkab mus txog 100 "OD.

API 5L Qib B, ASTM A106 Qib B thiab A53 Qib B, peb cov ntaub ntawv no yog cov ntaub ntawv siv ntau tshaj plaws hauv kev tsim cov kav dej lossis cov roj thiab roj thiab kev thauj mus los ua kua.

ASTM 106 Tube yog hais txog kub-dov los yog txias-draw (dov) seamless carbon steel yeeb nkab.

ASTM A53 yeeb nkab suav nrog welded thiab seamless steel kav ntawm cov khoom siv dub, thiab qee zaum kub-dip galvanized (galvanized).
