BHASTRIK MECHANICAL LABS design and manufacture bellows as per EJMA standards in all austenitic stainless steel, exotic metals like Hastealloy, Inconel and in non-ferrous materials like Brass, Cupronickels, Copper, and Phosphor-bronze.

Metal Bellows offer elegant solutions for most piping design problems involving thermal expansion, volume compensation, vibration isolation, etc. Bellows are manufactured by Hydro-forming operation or by expanding mandrel forming and rubber or elastomer forming processes.

Edge welded (Diaphragm) Bellows

BHASTRIK possess the capability to manufacture NESTING RIPPLE type edge welded diaphragm bellows in stainless steel AM350 and exotic metals including Hastealloy C-276 and Inconel 600, 625 or 718, in sizes ranging from minimum of 12 mm I.D. to 175 mm O.D. The precision-formed diaphragms are edge welded by micro plasma welding using special fixtures to prevent uneven stress build up. The thickness of diaphragms varies between 0.127mm and upward 0.30mm.

Convoluted Bellows

BHASTRIK manufacture convoluted bellows in stainless steel and exotic metals including Hastealloy C-276, Inconel 600, 625 and 718, of sizes ranging from 15 mm dia upto 450 mm. BHASTRIK also manufactures convoluted bellows out of brass, Cupronickels, copper and phosphor-bronze in sheet thickness from 0.15 mm and upwards, either seam welded or seamless. The sizes vary from minimum of 18 mm I.D. to a maximum of 75 mm O.D.

BHASTRIK attitude to experiment and innovate in the manufacture of metal bellows has led to the development of prototype exhaust system, hydroformed components, special welding fixtures, special purpose machines etc. These added with the in-house strength and infrastructure has helped BHASTRIK to develop newer products like pressed components, deep drawn components, thin walled fabrication and hoses for high vacuum application.
