Qhov txawv ntawm PSL1 Thiab PSL2 Pipes yog dab tsi

API 5L Steel Pipe Supplier-GNEE

Qhov txawv ntawm PSL1 Thiab PSL2 Pipes yog dab tsi?

 

API 5L kab yeeb nkab yog tsim nyob rau hauv ob hom, PSL 1 thiab PSL 2. Tab sis PSL yog dab tsi? PSL stands rau Product Specification Levels. PSL stands rau Product Specification Levels.

Cov kav dej yog siv nyob rau hauv ntau hom kev sib txawv, xws li corrosive thiab non-corrosive. Cov kav dej siv nyob rau hauv ib puag ncig corrosive hnyav xav tau cov khoom siv uas tuaj yeem tiv taus cov txheej txheem zoo li no. Ntawm qhov tod tes, tus qauv zoo qib yeeb nkab rau cov kev pabcuam ib txwm yuav ua rau lub hom phiaj.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Chemical Properties

PARAMETER	PSL1	PSL2
Chemistry: Max C rau Seamless yeeb nkab	0.28% rau qib siab dua lossis sib npaug B	0.0024
Chemistry: Max C rau Welded yeeb nkab	0.26% rau qib siab dua lossis sib npaug B	0.0022
Chemistry: Max P	0.03% rau qib siab dua lossis sib npaug rau A	0.0003
Chemistry: Max S	0.0003	0.0002
Carbon sib npaug:	Tsuas yog thaum tus neeg yuav khoom qhia SR18	Qhov siab tshaj plaws uas yuav tsum tau muaj rau txhua qib

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Mechanical Properties

PARAMETER	PSL1	PSL2
Yield zog, siab tshaj plaws	Tsis muaj	Qhov siab tshaj plaws rau txhua qib
UTS (Ultimate Tensile Strength) siab tshaj plaws	Tsis muaj	Qhov siab tshaj plaws rau txhua qib

Rau PSL2 cov kav dej, muaj kev txwv ntawm qhov siab tshaj plaws tawm los thiab lub zog tensile kawg, thaum rau PSL1 cov kav dej, ua tau raws li qhov yuav tsum tau muaj tsawg kawg yog txaus. Qhov thib ob qhov yuav tsum tau ua rau cov kav dej PSL2 yog tawg toughness, uas tsis tas yuav tsum tau rau cov kav dej PSL1.
