Bhastrik Mechanical Labs Pvt. Ltd. Perungudi, Chennai, Tamil nadu

the expertise gained by bhastrik mechanical labs in the manufacture of metal bellows has led to the development of toroidal and many odd shaped speciality bellows..

The Edge Welded (Diaphragm) bellows consists of two rings. These rings are edge welded together inside and outside. Edge welded bellows guarantee a very high flexibility. These bellows are used in measuring & control devices, mechanical seals for pumps, motors etc. BHASTRIK possess the capability to manufacture NESTING RIPPLE type edge welded 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 or laser welding using special fixtures to prevent uneven stress build up. The thickness of diaphragms varies between 0.127mm and upward 0.30mm.

Membrane Compensators are used for the absorption of changes in volume due to temperature difference (Insulation Oil In High-Voltage) Stainless Steel Diaphragms are pressed with a Special profile. They are welded together on their exterior diameter.

Running engines cause self vibration. To compensate for those movements and temperature differences resulting in thermal expansion, bellows are used to connect the exhaust gas pipes to the funnel.

convoluted bellows are thin walled cylindrical components. Their surface area features a corrugated structure which is perpendicular to the cylinder axis. Because of this corrugated structure the bellows are highly flexible during axial, lateral and/or angular. these bellows are used in valve sealing, pipe line construction, vibration absorbers, exhaust systems etc. bhastrik manufacture convoluted bellows in stainless steel and exotic metals including haste alloy c-276, inconel 600, 625 and 718, of sizes ranging from 10 mm dia up to 600 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

Our relentless endeavor and focus to develop special components for our customers led us to develop products like pressed, deep drawn components, thin walled fabrication for Cryo vessels, hoses for vacuum, nuclear and aerospace applications. To make things hassle free for our customers we undertake contract manufacturing run by a consortium of technically sound entrepreneurs who value challenging projects.
