API 5L ERW Carbon Steel Yeeb Nkab

 

API 5L pipeline kav dej muaj kev kub siab ua haujlwm, tsis tshua muaj kub toughness, thiab zoo weldability. Cov yam ntxwv no ua kom ntseeg tau tias API 5L cov kav dej muaj peev xwm tiv taus qhov kub siab thiab qis qis thaum thauj cov kua dej xws li roj thiab roj, tswj xyuas qhov zoo ntawm kev sib txuas thiab kev ua tau zoo ntawm cov kav dej.

Cov txheej txheem ntau lawm rau API 5L cov kav dej kav dej feem ntau suav nrog kev nruam casting, nruam dov, tho, thiab cov yeeb nkab kos duab. Thaum lub sij hawm tsim khoom, nws yog ib qho tseem ceeb los tswj cov txheej txheem cov txheej txheem los xyuas kom meej cov khoom ruaj khov thiab ua raws li cov qauv tsim nyog.

Vuam yog ib kauj ruam tseem ceeb hauv cov txheej txheem ntawm cov kav dej steel kav, nrog rau cov txheej txheem vuam xws li Electric Resistance Vuam (ERW). Thaum lub sij hawm vuam, nws yog ib qho tsim nyog los tswj qhov tsis xws li vuam kub thiab vuam ceev kom ntseeg tau tias qhov zoo thiab lub zog ntawm vuam seam.

Kev tshuaj xyuas ntawm API 5L ERW Steel Pipes:

1. Kev npaj ua qauv rau ntau yam kev xeem:
Tensile Test
CVN Impact Test
Guided Khoov Test
Hardness Test
Phaj Weld Bead Test
Pipe Weld Bead Test
CTOD (Crack Tip Opening Displacement) Test

2. CTOD Test Qauv:
Cov qauv yuav tsum tau muab los ntawm cov hlau weld, tshav kub cuam tshuam (HAZ), thiab cov hlau puag.
Kev npaj yuav tsum ua raws li cov cai ntawm ISO 12135, ASTM E1290, lossis BS 7448.

3. Hardness Test:
Base Hlau Hardness Test:
Ua siv Vickers txoj kev xeem raws li ISO 6507-1 lossis ASTM E92, lossis Rockwell HR15N txoj kev xeem raws li ISO 6508-1 lossis ASTM E18.
Nyob rau hauv rooj plaub ntawm kev tsis sib haum xeeb, yuav tsum tau siv Vickers xeem txoj kev.
HAZ thiab Weld Hlau Hardness Test:
Ua siv Vickers txoj kev xeem raws li ISO 6507-1 lossis ASTM E92.

4. Cov Cai rau Kev Ntsuas Hardness:
Hauv kev ntsuam xyuas hlau hauv paus, yog ib qho kev nyeem ntawv nyuaj tshaj qhov kev lees paub, nws tseem yuav suav tau tias yog:
Qhov nruab nrab ntawm tus nqi tsawg tshaj plaws ntawm peb lub ntsiab lus thiab tus nqi loj tshaj plaws ntawm rau lub ntsiab lus ntxiv nyob ze tsis pub dhau qhov kev lees paub.
Qhov kev nyeem ntawv ib zaug dhau qhov txwv tsis pub dhau 10 HV10 lossis 2 HRC (qhov twg yog qhov tsim nyog) tshaj qhov txwv.
