Expansion Joints for
Jenbacher Machinery – Stam Flex

Advanced Expansion Joints for Jenbacher
Machinery Enhancing Performance and Durability

Introducing Stam Flex’s high-quality metal expansion joints and compensators, designed to optimize the performance and longevity of Jenbacher machinery and engines. The metal expansion joints and compensators are efficiently used in generator sets, including Jenbacher generator sets. These expansion joints have a crucial role in the proper operation of engines like generator sets by absorbing expansions and vibrations within the system, ultimately ensuring optimal efficiency.

Therefore, we, as a leading Jenbacher joint manufacturer, offer flex connectors, exhaust bellows, and other custom expansion joints for Jenbacher industrial machinery. Here’s a detailed explanation of these expansion joints with a focus on Jenbacher machine applications:

Standard Components and Materials for
Exhaust Expansion Joints for Caterpillar Engines

Design Code

The expansion joints are designed according to the EJMA (Expansion Joint Manufacturers Association) code, which is a widely recognized industry standard for the design and manufacturing of expansion joints. This ensures that the joints meet rigorous engineering and quality standards.

Lifetime

The expansion joints have a remarkable lifetime of over 10 million cycles, indicating their durability and reliability in long-term applications.

Design Conditions

These expansion joints are suitable for use in pipelines and exhaust systems of generator sets operating at 1 barg (PN1) and temperatures of up to 550°C. These conditions are well-suited for Jenbacher generator sets, which often operate at high temperatures.

Materials

The expansion joints are constructed from 1.4828 (SS309S) refractory alloy stainless steel. It is capable of withstanding high temperatures up to 1,000°C. This material is corrosion-resistant and ideal for the harsh operating conditions commonly found in generator sets.

Sleeve

Optional inner and/or external removable sleeves can be provided for added protection and durability in specific applications.

Optimal Design

The expansion joints are manufactured with a single welding seam, which reduces the number of welds and minimizes torsional stresses. This design feature helps extend the lifetime of the compensator.

Connecting Flanges

The expansion joints come with loose carbon steel connecting flanges that are integrally mounted, ensuring no contact between the flanges and exhaust gases. This design minimizes the risk of corrosion and further extends the life of the expansion joint.

How do our metal expansion joints and compensators prevent generator failure?

1

Vibration Dampening

Gas and power generator sets often yield vibrations during operation, which can lead to accelerated wear and tear on components and increase the risk of failure. The expansion joints absorb these vibrations, reducing stress on the system and prolonging the life of critical components.

2

Thermal Stress Reduction

Generator sets, especially those used in industrial or high-temperature applications like Jenbacher generators, can experience significant thermal stress. We design metal expansion joints to handle high temperatures and help distribute thermal stress evenly. Also, it minimizes the risk of cracks or fatigue failures in the system.

3

Preventing Exhaust Gas Leakage

The loose flanges integrated into the expansion joint design ensure that there is no direct contact between the flanges and exhaust gases. This prevents corrosion and gas leakage, which can lead to operational inefficiencies and, in severe cases, catastrophic failure.

4

Extended Component Lifespan

By reducing the number of welds and torsional stresses, our expansion joints for Jenbacher contribute to the overall longevity of generator set components. This can lead to a longer operational life for the generator set and reduced maintenance costs over time.

5

Reliable Operation

We understand that generator sets are critical for backup power generation in various industries. Using high-quality expansion joints helps ensure the reliable and uninterrupted operation of these sets. Thus, Stam Flex ensures to provide customized expansion joints to reduce the risk of unexpected failures and costly downtime.

So, these metal expansion joints and compensators by Stam Flex play a vital role in enhancing the reliability and longevity of critical gas and power generation systems, including those used in Jenbacher machine applications.
