CovPEDdaim ntawv pov thawj thiabCPRdaim ntawv pov thawj rau seamless steel kav tau ntawv pov thawj rau cov qauv sib txawv thiab xav tau:

1.PED daim ntawv pov thawj (Cov Khoom Siv Hluav Taws Xob Cov Lus Qhia):
Qhov txawv: Daim ntawv pov thawj PED yog ib txoj cai nyob sab Europe uas siv rau cov khoom xws likhoom siv siabthiab seamless steel kav. Nws ua kom ntseeg tau tias cov cuab yeej no ua tau raws li kev nyab xeeb thiab kev ua tau zoo hauv European lag luam.
Scenario: Daim ntawv pov thawj PED siv rau cov cuab yeej siv siab thiab cov kav dej uas tsim, muag lossis xa tawm mus rau European lag luam. Nws ua kom ntseeg tau tias cov khoom ua tau raws li txoj cai lij choj hauv European Economic Area.
2.CPR daim ntawv pov thawj (Construction Products Regulation):
Qhov txawv: Daim ntawv pov thawj CPR yog lwm txoj cai nyob sab Europe uas siv raucov khoom tsim kho, suav nrog qee cov khoom siv thiab cov khoom siv hauv kev tsim kho.
Scenario: Rau cov kav dej seamless steel, yog tias cov kav dej no tau siv hauv cov qauv tsim lossis cov ntawv thov cuam tshuam txog kev nyab xeeb hauv tsev, lawv yuav tsum ua raws li cov cai ntawm CPR. Daim ntawv pov thawj CPR ua kom muaj kev nyab xeeb ntawm cov khoom hauv kev tsim kho.
Hauv cov ntsiab lus, daim ntawv pov thawj PED siv rau cov cuab yeej siv siab thiab cov kav dej cuam tshuam, thaum daim ntawv pov thawj CPR siv rau cov khoom siv thiab cov khoom siv, suav nrog qee cov kav dej seamless rau kev siv tshwj xeeb. Ob daim ntawv pov thawj yog los xyuas kom meej tias cov khoom ua raws li cov kev cai lij choj thiab kev nyab xeeb hauv European lag luam.

PED Certificate (Cov Lus Qhia Cov Khoom Siv Siab)
Cov qauv siv tau rau daim ntawv pov thawj PED thiab daim ntawv pov thawj CPR txawv.

PED daim ntawv pov thawj muaj feem xyuam rau cov cuab yeej siv siab thiab cov kav dej sib txuas. Nws cov qauv feem ntau suav nrog tab sis tsis txwv rau cov hauv qab no:

EN 10216 series qauv xws li EN10216-1 P235TR1; EN10216-2 P235GH; EN10216-3 P275NL1;

ASTM series cov qauv xws liASTM A106 GrB; ASTM A106 GrC;ASTM A53 GrB Cov Lus Qhia; ASTM A333 / A333M-18 Gr6;

EN 10210 S235JRH; EN10210 S355JOH; EN10210 S355J2H
- Cov qauv no npog seamless steel kav rau kev siv siab.

CPR Daim Ntawv Pov Thawj (Kev Tswj Xyuas Cov Khoom Siv Hauv Tsev)
Daim ntawv pov thawj CPR muaj feem xyuam rau cov khoom siv thiab cov khoom siv. Nws cov qauv feem ntau suav nrog tab sis tsis txwv rau cov hauv qab no:

EN 10219 series cov qauv EN10219 S235JRH; EN10219 S275J2H; EN10219 S275JOH; EN10219 S355JOH; EN10219 S355J2H, EN10219 S355K2H;

- Cov qauv no suav nrog cov kev xav tau rau cov hlau tsis muaj hlau thiab cov hlau zoo rau cov qauv tsim.

EN 10210 series cov qauv - EN10210 S235JRH;EN 10210 S355JOHEN10210 S355J2H, cov qauv no npog cov kev xav tau rau cov hlau kub-tsim qauv.

TS EN 10025 series cov qauv - Cov qauv no npog cov txheej txheem kev xa khoom rau cov hlau tsis muaj hlau tsis muaj hlau.EN 10255 series ntawm cov qauv

- Cov qauv no suav nrog qhov yuav tsum tau ua rau cov hlau tsis muaj hlau thiab cov hlau tsis sib haum rau cov kav dej tsis sib haum thiab welded steel rau dej thiab lwm yam dej.

Hauv cov ntsiab lus, daim ntawv pov thawj PED siv rau cov cuab yeej siv siab thiab cov kav dej cuam tshuam, thaum daim ntawv pov thawj CPR siv rau cov khoom siv thiab cov khoom siv, suav nrog qee cov kav dej seamless rau cov ntawv thov tshwj xeeb. Ob daim ntawv pov thawj yog tsim los xyuas kom meej tias cov khoom ua tau raws li kev cai lij choj thiab kev nyab xeeb ntawm European cim.
