CNG Cylinder

When the steel cylinders originally designed for compressed gas were produced in the Tube Rolling Mill of seamless tubes. At that time, the cylinders designed for compressed and light gases were produced.
In roce 1927, triple sales of steel cylinders were recorded in comparison with the previous year and, in the next years, the sales increased nearly three and half times again. The production was run on one press, with the throughput of 300 cylinders per month. The cylinders were made of seamless steel tubes rolled by the Mannesmann method, with the working pressure 125-150 bar, or the test pressure 190-225 bar, water volume 1-50 litres and 0. 125-7. 5003 of gas.
The bottoms and necks were forged in the Forge, heat treated in the Toolshop, machined, tested and assembled in the mechanical workshops. In 1938, the stages of steel cylinder machining, testing and assembly were relocated to the Small Machine Works. In the mid In the mid 1942, the new Tools Forge was finished and the old one was adapted to the Cylinder Forge-new series production was started.
In years 1931-33, 2, 400 cylinders were manufactures for Japan and during the World War II; the cylinders were exported to Denmark, Finland, Holland, Italy, Croatia, Romania, Sweden, Slovakia, Bulgaria. In spite of that, the greatest outlet for steel cylinders in in 1930`s a 1940`s was represented by the domestic market.
In 1943, the manufacturing facilities were installed to increase the monthly production from 6000 to 9000 cylinders. The Tools Forge was extended with the cylinder refining equipment and the cylinder furnace was also put into operation. , the steel cylinder production was rationalized remarkably. The steel cylinder testing room was built up in the Machine Works and the monthly throughput reached to 7, 500 units. During an air attack of the American bombers in August 1944, the steel cylinder workshop in the small Machine Works was hit by bombing and the production was stopped for more than one month. The production was resumed and the company's own proprietary semi-automatic machines and special cylinder-machining laths were put into operation. In January 1946, the annealing furnaces were commissioned in the former gas cylinder shop where the cylinders were annealed.
