welded vacuum bellow Features:
1) Varieties of bellows shape design: typical double "s" bellows shape design is
adopted by DB and DM and stress distribution design in the inner diameter on
the welding bead is adopted by DC and DH
2) More material can be selected: Meet the different needs of working conditions
3) More bellows sheet thickness can be selected: more bellows sheet thickness at the single or double layers can be supplied, for example 0.12mm, 0.15mm,
0.18mm
4) Abroad application ranges: used in joint welded metal bellows and bellows mechanical seals
