Cov pa roj carbon (c):

Cov pa roj carbon yog lub ntsiab lus uas cuam tshuam lub zog thiab hardness ntawm cov hlau.

Manganese (MN):

Manganese yog qhov tseem ceeb rau kev txhim kho lub zog thiab hardness ntawm cov hlau, thaum tseem pab tau tshem tawm cov kev tsis zoo ntawm cov leej faj.

Phosphorus (p) thiab Sulphur (s):

Phosphorus thiab cov leej faj yog cov khoom muaj teeb meem hauv cov hlau, uas txo cov plasticity thiab tawv ntawm cov hlau.

API 5L

Lub API 5L Pipeline Steel Yeeb Nkab Qauv tau tsim los ntawm American Petroleum Institute (API 5L PSL1 thiab API 5L PSL2, uas muaj qhov sib txawv ntawm cov tshuab tshuab:

1. Tawm los thiab tensile lub zog:

- PSL1: Rau cov qib sib txawv me ntsis, muaj tseeb yam tsawg kawg nkaus yuav tsum muaj rau lub zog zog thiab tensile lub zog ntawm PSL1, tab sis tsis muaj qhov txwv tsis pub tshaj. Piv txwv li, cov paib lub zog ntawm A25 tus qauv steel yog 172 MPA thiab lub zog tensile yog 310 mpa; Cov txiaj ntsig lub zog ntawm X70 qib yog 483 MPa thiab lub zog tensile yog 565 mpa.

- PSL2: cov txiaj ntsig lub zog thiab tensile lub zog ntawm PSL2 muaj qhov kev txwv ntau tshaj plaws ntxiv rau cov kev xav tau tsawg kawg nkaus. Piv txwv, cov txiaj ntsig muaj zog ntawm qib B Hlau yog}} mpa mpa mpa mpa, thiab lub tensile muaj zog yog} mpa; Cov txiaj ntsig lub zog ntau ntawm X70 qib steel yog {}} mpa mpa mpa mpa thiab tensile lub zog yog}} mpa.

2. Kev Ntsuas Xyuas:

- Ntawv Nkauj PSL1: Qhov kev ua haujlwm kev ua haujlwm tsis tas yuav.

- PSL2: Rau tag nrho cov qauv steel tsuas yog x8 {0}}}} Qib rau 41J, hloov pauv ntau dua lossis sib npaug ntawm 27J. X80 Qib Steel, tag nrho cov loj 0 Degree Akv nruab nrab: Ntev ntau dua lossis sib npaug ntau dua lossis sib txuas rau 68J.

3. Kev sim ua txhaum cai:

- PSL1: Tsis yog-kev ua kom raug kev sim los ntawm ceg tsis tas yuav tsum tau.

- PSL2: Tsis yog-kev puas tsuaj los soj ntsuam, xws li ultrasonic thiab xoo hluav taws xob tshuaj xyuas, yuav tsum tau nqa tawm ib qho los ntawm ib qho los ua kom muaj kev nyab xeeb thiab kev ntseeg ntawm cov raj xa dej.

4. Kev Kuaj Hydraulic:

- Ntawv Nkauj PSL1: Kev kuaj dej siab yog tsis tas yuav tsum ua.

- PSL2: kev ntsuam xyuas cov hydraulic yuav tsum tau nqa tawm ib qho los ntawm ib qho, thiab tsis muaj kev sim ua kom tsis txhob siv tau los hloov kev kuaj mob tes.

5. Carbon sib npaug (CEV) txwv:

- PSL2: txwv cov ntsiab lus carbon sib npaug, qhov twg cov roj av muaj ntau dua {2}}. 12%, sib npaug}. 12%. Cov CEQ txawv yuav tsum tau siv. Rau cov kab yeeb nkab cov kab, muaj lub zog tsawg tshaj plaws

Qhov sib txawv ntawm API 5L PSL1 & API 5L PSL2

1. Tawm los thiab tensile lub zog:

2. Kev Ntsuas Xyuas:

- Ntawv Nkauj PSL1: Qhov kev ua haujlwm kev ua haujlwm tsis tas yuav.

3. Kev sim ua txhaum cai:

- PSL1: Tsis yog-kev ua kom raug kev sim los ntawm ceg tsis tas yuav tsum tau.

4. Kev Kuaj Hydraulic:

- Ntawv Nkauj PSL1: Kev kuaj dej siab yog tsis tas yuav tsum ua.

- PSL2: kev ntsuam xyuas cov hydraulic yuav tsum tau nqa tawm ib qho los ntawm ib qho, thiab tsis muaj kev sim ua kom tsis txhob siv tau los hloov kev kuaj mob tes.

5. Carbon sib npaug (CEV) txwv

- PSL2: txwv cov ntsiab lus carbon sib npaug, qhov twg cov roj av muaj ntau dua {2}}. 12%, sib npaug}. 12%. Cov CEQ txawv yuav tsum tau siv. Rau cov ntawv sib xyaw psl2, muaj lub zog tsawg tshaj plaws.
