1) Aerospace :-
Metal seals are utilized as a part of a wide assortment of utilizations in aviation. Extraordinarily the turbine motor area. Since the temperature in motor crosses the breaking points of elastomeric seals the main ideal arrangement is metal seals. For high temperature applications fascinating materials like hastealloy, Haynes, Inconel and Eligiloy can be utilized.
Type of seals used:
• Spring energized C-rings - Shaped as well as circular seals.
- • Metal O-ring - Shaped
- as well as circular seals.
- • Gas filled metal o-ring - Shaped as well as circular seals.
• Spring energized C-rings - Shaped as well as circular seals.
2) Oil & Gas, Power Generation :-
In oil and gas applications metal seals are highly preferred. In applications like deep sea where the pressures are extreme and the environment is corrosive special seals are made. At times they are gold plated for excellent performance. In power generation these seals are used to seal various parts of turbine section.
Type of seals used:
- • Metal O-ring - Shaped as well as circular seals.
- • Spring energized C-rings - Shaped as well as circular seals.
3) Military :-
Metal seals are used in a wide variety of areas in military and defense field. C-seals are used in the night vision systems which is a crucial part of today’s defense technology. Also metal seals play an important part in space application. PTFE coated c-seals and spring energized c-seals are used in cryogenic applications.
Type of seals used:
- • Metal O-ring - Shaped as well as circular seals.
- • C-ring - Shaped as well as circular seals.
4) Plastic Molding :-
We manufacture metal o-ring seals used in sealing the leakage path between nozzle and manifold of Hot Runner systems. The seal (SS321 material) is hollow with a small vent hole on the ID. Due to its hollow structure the polymer enters in through the vent hole and provides internal resilience. This internal resilience keeps the seal inflated which prevents the leak.
Type of seals used:• Metal O-ring - circular seals.
5) Reactors and Nuclear Installations :-
As we are aware that Nuclear energy is the best source to produce energy w.r.t. the cost involved and its return on investment. With the ever increasing no. of nuclear installations and the risk of radiation it is important to seal the vessels at its highest limit. In achieving the goal of optimum sealing metal seals like, c-rings and spring energized c-ring seals play a very crucial role. To achieve the desirable leak tightness for extended period of time spring energized c- seals with Nimonic 90 spring and 2 layers of jackets, viz – Inconel and Aluminum are used. Metal seals are also used in the nuclear waste containment. Seals with various shapes, like race track, oval, square are manufactured for special applications.
Type of seals used:
• Spring energized C-rings - Shaped as well as circular seals.
- • Metal O-ring - Shaped as well as circular seals.
- • Gas filled metal o-ring - Shaped as well as circular seals.
• Spring energized C-rings - Shaped as well as circular seals.
6) Heavy Duty Mobile, Transportation Automotive :-
C-ring seals have been accepted as a good solution for sealing turbochargers. Also shaped seals have been accepted in sealing the engines of high end sports cars.
Type of seals used:
- • Metal O-ring - Shaped as well as circular seals.
- • C-ring - Shaped as well as circular seals.
7) Semiconductor and Vacuum :-
Metal seals are widely used in the semiconductor industry. The application is in the sealing of laser instruments used to manufacture semiconductor components. Metal seals with various plating’s are widely used in vacuum applications. Especially when the leak tightness requirements are very high i.e. 1 x 10*-9 mbar.lit/sec and above (helium leak tightness). Metal seals like c-rings and spring energized c-rings with copper, silver and tin plating are commonly used in accelerators, RF applications and so on.
Type of seals used:
• Spring energized C-rings - Shaped as well as circular seals.
- • Metal O-ring - Shaped as well as circular seals.
- • Gas filled metal o-ring - Shaped as well as circular seals.
• Spring energized C-rings - Shaped as well as circular seals.
