No constraint theinflation festival

No constraint theinflation festival has powerful support and directional properties. Very reliable columnar stability, change in the past axial type theinflation festival easy happening "twisted" and instability phenomena, corrugated GuanBo, and several more by using multi-level, compensation volume etc.
Nominal pressure: (Mpa) 0.25 ~ 2.5
Nominal diameter: DN25 ~ DN2500
