Stork's Blading Bulletin is our bimonthly e-zine to keep you posted on the latest news in the world of turbo blading.
Stork has supplied blades all over the world in different configurations for HP, IP & LP rotors. This spotlight concerns primarily the largest L-0 Blades as these are the most difficult to manufacture. In most cases they are manufactured from a closed dye envelope forging, but when a customer has an urgent inquiry due to unforeseen circumstances we are also able to manufacture most blades from a forged bar to get the turbine operational again in as little as five weeks.
Stork is actively tracking, developing and expanding the portfolio of the latest iterations of F-Class & H-Class Gas Turbine compressors, and are already supplying these compressor blades & vanes to several customers worldwide. In this spotlight we would like to focus on the General Electric Frame 7 FA+E gas turbine compressor, as we are actively tracking and Reverse Engineering the various design iterations for this specific compressor and turbine. For example, we have been keeping track of the various design modifications for the Frame 7F which include the compressor and the turbine, ranging from the 150 MW 7F to the 171 MW 7FA+E.
The Innovation Cluster Drachten (ICD) is an international ecosystem of eighteen (18) high tech companies & institutions, with innovation as its primary goal. The cluster is based in the Netherlands but oriented globally, and has its eyes set on “The Big Five of High Tech”. The ING Bank described the Innovation Cluster as “One of the Pearls of the Industry in the Netherlands.” Stork is proud to join this cluster and participate to innovate and share knowledge. Stork is able to contribute to this cluster with its vast knowledge of and experience with high-precision manufacturing, LEAN production methodology and Reverse Engineering capabilities.
The Duchenne’s Disease is not well known but the impact is quite severe. One of our employees, Johannes Groen, is undertaking a journey organized by Dutch charity organisation Duchenne Heroes to raise awareness and money for research and development of a new treatment. Stork actively supports his 700 km off-road mountain-bike tour.
Historically, most boys who have it do not survive beyond their mid-twenties, and those that do will be using a wheelchair by age 12 and experience social isolation. The simplest of tasks become difficult, and in the later stages, heart and breathing muscles begin to fail. Nearly 300,000 boys are living with the disease worldwide. The disorder knows no cultural, economic, or social boundaries.
Duchenne's Disase is a rare hereditary condition which causes muscle dystrophy and loss of muscle mass. It usually only occurs in boys and the first signs of this terirble disease can be detected as young as two years of age. Duchenne occurs one in every 4000 newborns, and there is no known cure.
It is caused by a lack of Dystrophine in the X-chromosome and causes a lack of proteins in the muscle cell's wall. This in term causes mucle dystrophy, and eventually causes the death of these muscle cells rendering people who suffer from this condition unable to use their muscles.
In recent years we have both observed and got request from OEM's to CNC polish compressor blades and vanes to optimize flow efficiency and minimize differences due to tolerances in blade geometry, which is essential to the balancing of the compressor rotor and the fit of the stator parts. In order to keep up with the demand of this for the latest F-Class & H-Class Gas Turbine Compressors, Stork has invested in a new 6-axis CNC Grinding and Polishing machine specifically made for the purpose of CNC Grinding.
The company IMM Machinenbau GMBH from Germany has design and delivered this machine in close cooperation with us, to ensure that it is completely optimized for turbine blades and other turbomachinery components. This investment allows us to supply both the OEM and the End User with the highest quality blades possible to optimize your asset performance.
This CNC-Machine allows us to automatically polish all rows of the Gas Turbine Compressor, as well as most rows of Steam Turbine Blades. As such this allows us to increase our annual production output and speed up the manufacturing process of these blades, to ensure your turbine is up to speed in no-time.
Stork is always looking for new and innovative ways to manufacture Turbo Machinery Components, and 3D Printing is a method that we are likely to see more and more of in the future. Our interests primarily peak with the additive manufacturing of stainless and super alloys, but we are also interested in how innovative techniques can decrease day to day operational costs such as the manufacturing of custom tools and specialized fixtures for high accuracy CNC Milling. In light of this, Stork has recently acquired an Ultimaker 2+ to test this very purpose. 3D FEM (Filament Extrusion Method) Printing of Polymers is a process with a high relatvely high accuracy (± 0.05mm)
In May 2017 Stork & AES Corporation, Mitsui and Co Ltd and Nebras power cooperated to achieve a solution for an unexpected challenge, namely the manufacturing of fourteen large LP-0 Blades for an OEM steam turbine at IPP Plant, located near Amman, Jordan. The blades needed to be replaced due to crack initiations in the curved side entry root. The cracks were found during a planned outage, although they did not expect to find any cracks during this inspection. When the cracks were discovered, a solution had to be found quickly in order to supply the required power for the summer season. Spare blades were not available and a long delivery time seemed to be the only option. These blades are normally made from closed die envelope forgings, which usually take more than six months to be made. Stork manufactured these replacement blades from a higher grade bar material to minimize downtime.
At Stork we value our Quality Management and Assurance as much as we value Health, Safety and Environmental concerns. (HSSEQ) Stork Turbo Blading has recently succesfully upgraded their Quality Management system to the latest international standard, ISO 9001:2015. This new quality management system has made several important changes in regards to how quality assurance is achieved and who benefits from this the most.
For several years now Stork has been able to supply the latest design evolution for the frame 7EA Compressor, namely the "Compressor Robustness Enhancements" upgrade as implemented by General Electric and described in GEA32211...

Selecting the right material is detrimental to proper form, fit and function of any component. Positive Material Identification is one of the tools used to give an extra level of certainty when it comes to reverse engineering and proper material selection.
At Stork we value Health & Safety above all else. As such, a clean and safe working environment is of utmost importance.
