Seamless Cov yeeb nkab uas loj tshaj plaws hauv Caliber

API 5L duav seamless thiab cov hlua khi hlua. Qhov no yog cov yeeb nkab rau kev xa dej mus rau hauv cov roj thiab cov roj siv hluav taws xob. API 5L yog tsim rau kev xa roj, dej, thiab roj hauv cov roj thiab roj cua. Nws muaj xws li cov txheej txheem-nyhav-xaus, ...

API 5L duav seamless thiab cov hlua khi hlua. Qhov no yog cov yeeb nkab rau kev xa dej mus rau hauv cov roj thiab cov roj siv hluav taws xob. API 5L yog tsim rau kev xa roj, dej, thiab roj hauv cov roj thiab roj cua.

Nws muaj xws li cov txheej txheem ntsuas phaus-qhov kawg, qhov phom sij, qhov tshwj xeeb dawb, xaus-yawg, tshwj xeeb kawg-qhov kawg, cov yeeb nkab-dawb thiab lub cev muaj zog thiab muaj zog ntxiv yeeb nkab zoo li tswb thiab ntaus kis las thiab ntawm kab-sib-khiav kab (TFL) yeeb nkab.
Qhov ntau ntau tsuas yog tsim los ntawm cov khw tsim nyog.
Cov qib kawm tau ua los ntawm qhov kev qhia no yog A25, A, B, X42, X46, X52, X56, X60, X65, X70, X80. Ob tug lej tom qab qhov "X" qhia tau tias Yam Tsawg Tshaj Tawm (hauv 000 tus psi) ntawm cov yeeb nkab uas ua rau hauv qib no.

TXAWJ LOS NTAWM ASTM A106 / ASTM A53 PIPES / API 5L
ASTM A106: npuaj cov hlau tsis sib haum rau kev siv tshuab siab (thiab kev kub txog 750 degree F)
ASTM A53: npog dub thiab kub dip galvanized carbon steel kav rau cov qis / theem siab thiab kev ua lag luam txhua yam
Txoj kev xeem cov yeeb yam uas feem ntau overlaps nrog A53 / A106 yog API 5L Gr. B, uas siv kab kav dej. Cov kev soj ntsuam no peb muaj nyob rau hauv cov ntsiab lus ntawm cov tshuaj lom neeg muaj pes tsawg leeg, cov khoom lag luam: Ib txhia tuam txhab lag luam yeej kos tib lub sijhawm / txuas ntawm cov yeeb nkab uas muaj peb qhov qauv rau tib lub sij hawm los qhia txog lawv cov kev hloov. Vim tib qho no, nws kuj yog ib qho tseem ceeb uas cov neeg muab khoom siv qhia API 5L lossis A106 kav dej yog tias lawv tau txais kev nug txog A53 kav.
Hais tias, lub ntsiab sib txawv ntawm A106 thiab A53 kav yog:

  • Kev Txhim Kho: A106 kav xa dej muaj nyob rau hauv kev sib txeeb, qhov twg A53 kav yog velded lossis seamless

  • Kev kub siab: A106 kav dej uas siab ntau dua thiab qhov kub thiab txias

  • Tshuaj lom neeg muaj pes tsawg leeg thiab cov khoom vaj khoom tsev (saib cov kab hauv qab)

Raws li txoj cai ntawm tus ntiv tes xoo, A106 kav dej muab nkag thaum kev quamless thov yog thov, A53 thaum raug ntes ua haujlwm zoo dua rau cov nqi tsim nyog.
