Abstract High -} Cov Khaub Ncaws Ncaws Pob Ua Haujlwm, thiab yooj yim}}}}}}} Ua hauj lwm zoo thoob plaws cov chaw lag luam, los ntawm cov dej hauv nroog thiab roj av Tes hauj lwm rau chav kawm kev nyab xeeb nuclear hwj chim cog piping daim ntawv thov.
Lub sijhawm ntev - sij hawm kev ntseeg tau ntawm cov tshuab ntxhua khaub ncaws ntawm lub taub hau {}}} Cov ntsiab lus tsis txaus ntseeg hauv kev ua haujlwm hnyav thiab ib puag ncig.
Qhov kev tshuaj xyuas no ua lub hom phiaj dua ob lub hom phiaj rau vuam - kev sib koom tes rau lub pob tw (BFW) ntawm cov kav dej HDPE.
Qhov tseem ceeb vuam tsis xws li fusion kub, thiab cua sov / txias cov saw sib txuas thiab ua kom sib koom tes yog piav qhia.
Cov qauv tseem ceeb tau soj ntsuam rau lawv cov lus qhia sib txawv, tsis pub dhau qhov xav tau kev sib raug zoo hauv ntiaj teb cov lus qhia thoob ntiaj teb.
Cov Qauv Kev Ntsuas Weld thiab kev nce qib tsis ntev los no hauv kev ntsuas me me, xws li los ntawm kev ntsuas luv thiab qeeb qeeb kev loj hlob (Scg), tau raug saib xyuas qeeb. Emerging approaches such as, tapered-waist tensile (TWT) specimens, and hydro-axial tension (HAT) evaluating the full joint thickness, offer steps toward addressing the pronounced limitations of existing test methods revealed.
Txoj kev ntsuam xyuas xaus los ntawm kev qhia cov kev tshawb fawb tseem ceeb, suav nrog ntau txoj kev sib tw, thiab kev yoog raws li cov leeg sib txawv, ua rau}}} phab ntsa HDPE kav.
Hais txog cov teeb meem no yog pivotal rau kev nce qib bfw kev ua tau zoo, txuas ntxiv} {{{{- stakes engineering cov ntawv thov.
