Expantion welding time need to nitrogen open?

[@syedkareemTRANEAC]

@AshinAnto-hp7cc if welding separately no need nitrogen
If welding in system if possible u can use nitrogen that's great

Hello sir, How do know the valve is not good? I want to learn.

[@syedkareemTRANEAC]

Check by pressure gauge

[@syedkareemTRANEAC]

@tanvirulalam9960 when system is running check suction pressure will come down
