SS321 flexible metal bellow hose can be supplied with or without stainless steel wire braiding.Wire braiding can be single or double.Generally,an external layer of SS wire braid is provided on corrugated flexible metal bellow hose,as an unbraided hose tends to elongate axially when pressure is applied.Some customers may even choose two or even three layers of braiding for high pressure applications. The braiding is highly flexible and follows the movement of the hose.
SS321 flexible metal bellow hoses offer very high-pressure resistance,vacuum tightness,thermal stability and corrosion resistance.
