conveniently
2, It adopts there-dimensional eccentric elasticity and multiple layers
hard sealing configuration, the thermal capability can reach zero leakage.
3 No flange configuration makes pipe elegant and binding up conveniently.4.
High temperature resistant, high pressure resistant, antisepsis ,
wearable
