  Cov qauv ntawm cov tubing coupling yog

  Cov tubing kawg thiab sab hauv phab ntsa ntawm lub coupling yog txuas nrog conical xov, thiab tubing kawg ntawm lub coupling lub cev yog kev cob cog rua ntawm ca xov nrog tib xov thiab suab, uas muaj cov yam ntxwv ntawm relieving cov kev nyuaj siab concentration ntawm lub hauv paus ntawm lub coupling. Cov xov sab nraud ntawm cov tubing txuas nrog ib lub khob hliav qab, thiab tsis yooj yim los tsim kev qaug zog thiab tawg, thiab cov txiaj ntsig kev sib txuas yog qhov zoo thiab zoo tiv thaiv kev sib tsoo ntawm cov roj zoo txoj hlua tawg.
