Products Description

No Flaring Metal Bellows is a type of bellows that has been designed to absorb thermal expansions and avoid pipe vibration. It is a flexible piece of equipment that can provide an effective solution for a wide range of applications in various industries, including aerospace, defense, energy, and medical. Non-expanding metal bellows are typically made from high-quality stainless steel, which not only provides excellent durability but also resists corrosion.

If high-temperature nickel-based alloy materials are used, this product can be used in the high-temperature area of the stack, they can withstand high and low temperatures, high pressures, and other harsh environments. By using non-expanding metal bellows, SOFC/SOEC can ensure smooth and safe operations, reducing downtime and maintenance costs.

advantage

Melting equipment

The temperature of the electron beam is instantly high, the high melting point metal can be melted quickly, and the temperature is released evenly. The vacuum environment during processing prevents the oxygen content of the material from rising and ensures the material performance.

Plate rolling equipment

Thk0.076 mm~8 mm nickel base alloy, titanium alloy, zirconium alloy plate, strip and foil processing.A complete production line, large tonnage, good precision, and strong product consistency. Various metal plates, strips and foils can be customized according to customer requirements.

Pipe production equipment

High productivity, convenient specification change during production, high flexibility, can obtain pipes with smaller diameter, thinner wall thickness, higher dimensional accuracy, lower surface roughness, better performance and various cross-sectional shapes .

Processing technology

Our metal bellows first uses metal foil to make welded pipes, and then makes molds after calculation. The forming method is to inject liquid into the inside of the welded pipe, and limit the shape through the mold. After two presses, the final shape is formed.
