What kind of piping connection methods are used for the face seal, tube weld, and compression fittings of AP, SL, AZ, AK , and BP series process gas equipment?

Face seal fitting: A metal gasket is set at the end of the sleeve to form a seal by tightening the nut. It allows for high sealing performance from vacuum to positive pressure.
Tube welding: Piping is performed by butt welding. This option is selected when the product is to be welded directly to the pipe tube or when the user plans to weld another joint to the product.
Compression fitting: This is a biting tube fitting that uses a double ring called a ferrule to bite into the piping tube by tightening the nut.
