FAQ
Q1. Cov khoom siv dab tsi yog cov kav dej loj ua los ntawm?
Cov dej hauv dej feem ntau yog ua los ntawm cov khoom siv ruaj khov xws li hlau, PVC thiab HDPE. Qhov kev xaiv ntawm cov khoom yog nyob ntawm daim ntawv thov tshwj xeeb thiab ib puag ncig.
Q2. Dab tsi yog welded kav thiab kauv seam kav?
Welded yeeb nkab yog tsim los ntawm kev sib koom ua ke ntawm ob lub npoo ntawm cov yeeb nkab ua ke, uas muaj cov qauv tsim muaj zog thiab xau. Kauv seam yeeb nkab yog tsim los ntawm dov ib tug ca hlau strip rau hauv ib lub raj zoo, uas muaj ntau yooj yooj yim nyob rau hauv tsim thiab daim ntawv thov.
Q3. Kuv yuav xaiv txoj cai pipeline li cas rau kuv qhov project?
Xav txog tej yam xws li hom kua uas raug xa tawm, kev xav tau siab, thiab ib puag ncig. Kev sab laj nrog tus kws tshaj lij tuaj yeem pab xyuas kom koj xaiv cov tubing zoo tshaj plaws rau koj cov kev xav tau.
