API 5L PSL1 (Theem Khoom Tshwj Xeeb Qib 1)
API 5L PSL1 yog qib theem zoo rau seamless thiab welded steel kab xaim roj uas siv rau hauv cov roj, roj, thiab dej hauv cov roj av thiab ntuj muaj kev lag luam. Nws yog qhov feem ntau dav siv cov lus tshwj xeeb yog nws qhov sib npaug ntawm kev ua tau zoo, nqi-ua hauj lwm zoo, thiab muaj peev xwm.

Cov tau txais thiab siv tau

Txheem:API cov lus qhia 5l (American Petroleum lub koom haum).

Hom Khoom:Carbon Steel thiab cov me-alloy steel.

Txoj kev tsim khoom:

Tshuaj lom neeg muaj pes tsawg leeg

PSL1 muaj cov tshuaj tswj tau tsawg dua piv rau PSL2. Cov yam ntxwv tseem ceeb:

Kev Cuam Tshuam Kev Ntsuas (Charpy V-thav duab) - Xaiv rau PSL1

Tsis yog yuav tsum tau uaTshwj tsis yog hais tias teev los ntawm tus neeg yuav khoom.

Yog tias yuav tsum tau, sim ntsuas kub thiab lub zog yuav tsum tau pom zoo.

Kev Ntsuas Hardness

Tsis muaj tawv tawv tawv txwv(Tsis zoo li PSL2, uas yuav xav tau HRC tsawg dua los yog sib npaug rau ntawm 22 rau kev pab los ntawm cov kev pab cuam).

Kev Xeem Yuav Tsum

PSL1 cov kav dej uas tab tom sim ua kom ntseeg tau tias lawv qhov ua tau zoo thiab ua tau zoo. Cov kev ntsuam xyuas no suav nrog:

Hydrostatic Kuaj: Txhawm rau xyuas cov yeeb nkab muaj peev xwm tiv taus sab hauv siab.
Tensile kuaj: Txhawm rau ntsuas cov txiaj ntsig lub zog, lub zog lub zog, thiab elongation.

Advanced soj ntsuam xws li pob txha lov todure thiab cuam tshuam tsis tas yuav tsum yog tsis xav rau PSL1 kav, tshwj tsis yog cov neeg siv khoom.

Qhov zoo ntawm PSL1 dhau PSL2
