this pipe with life.

deposited in the process media debris scraped the ball again, under the seat with a spring pressure and
temperature changes have compensation guarantee does not have any leaks.

material resources.
-Prefabricated heat preservation reduce the amount of heat loss.
-Due to the special structure, the normal use warranty is 20 years.
