Single SS (Stainless Steel) Expansion Bellows are specialized, highly durable components designed to absorb mechanical movement and thermal expansion in piping systems. These bellows play a critical role in minimizing stress and protecting the integrity of pipelines, vessels, and equipment subjected to high temperature and pressure environments. They are commonly used in industries such as oil and gas, power generation, chemical processing, and HVAC systems, where reliability and performance are essential.

Size Range: 40nb to 4000nb
The single SS expansion bellows are available in a wide size range, catering to various industrial applications. With sizes ranging from 40nb to 4000nb, these expansion bellows offer flexibility in installation and are suitable for small-scale as well as large-scale piping systems. The size range ensures compatibility with a vast array of industrial systems, meeting the specific demands of different sectors.

Temperature Range: Up to 2000°C
One of the key highlights of single SS expansion bellows is their ability to withstand extreme temperatures. With a temperature range of up to 2000°C, these bellows are engineered to perform under intense heat, making them ideal for high-temperature applications. Whether used in furnaces, exhaust systems, or steam pipelines, the SS bellows ensure long-lasting performance without compromising the safety and efficiency of the system.

Pressure Range: Up to 100 Bar
In addition to high-temperature tolerance, single SS expansion bellows can also handle substantial pressure. With a pressure range of up to 100 bar, these bellows are designed for use in high-pressure environments, providing exceptional durability and resilience. This makes them suitable for applications in industries such as oil refineries, petrochemical plants, and power stations, where high-pressure operations are a standard.

Types of Welded SS Expansion Bellows
Single SS expansion bellows are available in different types of welded constructions, which ensure optimal performance in varying conditions. Some of the most common types include:

1. Axial Expansion Bellows:
   Axial expansion bellows are designed to absorb axial movement, which refers to linear expansion or contraction along the axis of the pipeline. These bellows are widely used in systems where the primary concern is thermal expansion, ensuring smooth operation without additional stress on the piping.

2. Lateral Expansion Bellows:
   Lateral expansion bellows are built to handle lateral movement, allowing flexibility in directions perpendicular to the axis of the pipe. These bellows are often used in applications that require accommodation of both axial and lateral movements, making them highly versatile.

3. Angular Expansion Bellows:
   Angular expansion bellows are specifically designed to absorb angular deflections. These bellows are used in situations where the pipeline experiences bending or angular movement due to misalignment or shifting loads, ensuring minimal stress on the system.

4. Universal Expansion Bellows:
   Universal expansion bellows are composed of two or more bellows units connected by a pipe section. They are capable of absorbing a combination of axial, lateral, and angular movements, making them suitable for complex piping systems with multiple directional movements.
