** 1. Dab tsi yog qib L360? **
L360 Yeeb Nkab yog qib kawm hauv API 5L tus qauv, sib npaug rau ** x52 ** (tawm los dag zog ntawm 52, {4 4}} psi lossis 360 mpa). Nws yog feem ntau siv nyob rau hauv cov roj thiab roj pipelines thiab muaj nyob rau hauv ob qho tib si ** PSL1 ** (cov ntawv yuav tsum tau) thiab ** PSL2 ** (txhim kho kev nruj thiab kev sim ua ntu zus.
** 2. Dab tsi yog 3 qib ntawm cov yeeb nkab steel? **
Cov qib ntawm cov yeeb nkab ntau xws li:
- ** API 5L Qib X42 ** (Tawm lub zog 42, 000 psi \/ 290 mpa).
- ** ASTM A106 qib b ** (nruab nrab ntawm cov hlau roj carbon hlau rau qhov kev pab kub-ultrasonic.
- ** ASTM A53 qib b ** (General-hom phiaj carbon hlau yeeb nkab rau cov qauv \/ tshuab siv).
** 3. Dab tsi yog ASTM A106 FR cov khoom siv yeeb nkab? **
ASTM AN1 {{{{0 6 qib 6 qib 6 carbon steel hlau ** Cov khoom siv yeeb nkab tsim rau kev pabcuam kub. Nws muaj pes tsawg leeg suav nrog {{4 4}}. 30% Carbon, 0.29-1.030 tus lej ntawm silicon, thiab sulphorus, thiab leej faj. Nws muaj tsawg kawg yog cov txiaj ntsig lub zog ntawm 35, 000 psi (240 MPa) thiab tensile lub zog ntawm 60, {} psi (415 MPA).
** 4. Cov khoom siv yog x60 yeeb nkab ua los ntawm? **
X60 yeeb yog ua los ntawm ** High-zog qis-alloy (hsla) hlau **, muaj cov carbon, thiab cov kab hlau, vanadium, lossis titanium los txhim kho lub zog thiab weldability. Nws yog ua raws li tus ** API 5L ** tus qauv.
** 5. Dab tsi yog x60 street qib? **
X60 yog A ** rau cov pipeline stamp ** Rau ib API 5L, nrog tsawg kawg yog 60, {} psi (414 mpa). Nws yog siv rau hauv cov roj muaj zog thiab muaj roj thiab muaj nyob rau hauv ** PSL1 ** (qauv) lossis ** kev sim ua kom muaj zog thiab kev ntsuas stricter).
