Developing longer lasting expansion joint solutions with cost-effective fabric material replacements

Recognizing the need for expansion joint replace-ments to meet the high temperatures, high gas velocity and varying pressure conditions existing in the gas turbine exhaust environment, EagleBurg-mann routinely collaborates with several leading turbine manufacturers to address the challenges unique to their engines.

The gas turbine industry is continuously developing new technology to meet the demands and require-ments for greater output and reliability. Minimizing fuel costs, improving efficiency and environmental responsibility to reduce emissions are important factors.

EagleBurgmann has been supplying KE® fabric ex-pansion joints for gas turbine power plants for more than 40 years and has 40% of the fabric expansion joint market share within gas turbine power plants today.

KE® fabric expansion joints with round or rectangu-lar frames are installed to obtain movements, vibra-tions and misalignments, often in exhaust gas and low pressure in ducting systems.

Recognizing the need for quality expansion joints to meet temperatures up to 680 Deg. C, high gas velocity and varying pressure conditions exiting in the gas turbine exhaust environment, EagleBurgmann collaborate with many turbine manufacturers to address the challenges unique to their engines.

Gas turbine expansion joints are built using a combination of our high performance PTFE/woven fiberglass fabrics and steel (stainless or carbon) frames. Integrating high quality insulation, proven frame design and highly durable materials, this line of expansion joints are optimally engineered to withstand thermal shock and compensate for both movement and intense sustained heat.

Turnkey replacementWithin the gas turbine system, the connecting duct is exposed to a combination of thermal stress, turbulence and considerable vibration - an environ-ment uniquely suited to fabric expansion joints. De-signed to compensate for these extreme conditions, expansion joints consist of a flexible fabric mate-rial connected to a steel frame. In addition to full frame drop-in units, EagleBurgmann offers turnkey soft part replacements for existing steel frames to provide our customers with significant cost savings.

Proven Technology for MHI 501/701F OwnersEagleBurgmann’s success with Mitsubishi Heavy Industries (MHI) 701F gas turbines is just one example of our proven capability in providing a long-term solution for turbine owners. In 1995 our research and development design team at our Ve-jen facility began to concentrate on developing a fabric replacement for these specific turbines. As a result of extensive research, analysis, engineer-ing and testing which included vibration, tempera-ture and high cycle fatigue testing, turbine owners worldwide now experience longer lasting expansion joints.

A refirbishments starts with a replacement planning schedule with work breakdown schedules from start to finish (including time schedule, every day activities, relationships between activities and customer specific requirements).

Soft part replacements for existing steel frames (as shown above) can provide turbine owners with a significant cost savings.

EagleBurgmann can replace fabric expansion joints, eg. EE-00,

EE-01, EE-02, EE-03, EE-04 and IE-01 in exhaust systems behind

all generations of M251, M501 and M701.

Fabric material replacement for an expansion joint on a MHI 701F gas turbine exhaust at a Combined Cycle Power Plant in China. These durable fabric replacements have lasted 6 years in service with 1200 cycles on 9 units including 3 units for the Guangdong Shenzhen Qianwan Combined Cycle Power Plant (owned by Shenzhen Guangqian Electric Power).

EagleBurgmann is testing a varity of fabric materials. Upgrading materials will improve life cycle. Low cycle fatique (LCF) test rig.High cycle fatigue testing is performed on our fabric materials with test conditions of 650°C, frequency 90 Hz, and amplitude of 2.4 mm.

Vibration test - there is no damage after high frequency vibration.

Above examples of hot spot evaluation with a thermographic camera. The camera can measure surface temperatures without contacting the expansion joint. This means that an expansion joint located 20 metres above the ground on top of a boiler can be analysed. A developing hot spot can be detected at early stages and its rate of development will indicate the seriousness of its cause. Temperature of individual bolts, flanges and expansion joints can be analysed. A thermo-graphic analysis can estimate the life time of an expansion joint.

Fabric expansion joints are constantly being developed and tested to meet the needs within the gas turbine industry. The result of extensive reserarch, analyssis and testing has resultet in a fabric replacement for MHI units.
