CSM Corporation optimally selects the characteristics of both metals and non-metals to meet various needs such as low reaction force, large expansion and contraction, corrosion resistance, wear resistance, weather resistance, and vibration resistance. The "Technical Documentation for the Design of Expansion Joint" introduces the design of expansion joints, installation of expansion joints, SI unit conversion tables, pipe expansion tables, dimensions and mass of steel pipes, and basic dimensions of flanges. For more details, please contact us or refer to our catalog.

Non-metallic expansion joints have a very flexible ductility that cannot be achieved with metal, and by selecting the optimal materials, we provide products that excel in water resistance, oil resistance, and weather resistance. Additionally, they are equipped with heat resistance that allows for use at temperatures above 1000°C with special coating materials or composite materials. We offer high-temperature duct expansion joints, dust covers, flexible shoots and ducts, vibration-absorbing bellows, piping expansion joints, special heat-resistant expansion joints, and special corrosion-resistant expansion joints. For more details, please contact us or refer to our catalog.

Metal bellows used in harsh environments such as boiler outlets have been plagued by corrosion issues caused by complex internal gases. The metal bellows with Teflon sheet lining, produced using CSM's patented method, combines the airtightness of metal with the excellent corrosion resistance of Teflon. Since the internal gas does not come into contact with the metal bellows, it is not subjected to damage such as pitting or stress corrosion. Additionally, the structure prevents corrosive liquids from condensing and accumulating directly in the valleys of the bellows, achieving a longer lifespan for the bellows.

The ultra-low reaction bellows made of metal telescopic pipe fittings have been developed using thin-walled materials and maximizing the height of the corrugations to achieve ultra-low reaction performance. This allows for a large amount of expansion that traditional metal products could not accommodate, making it possible to replace non-metal products. It can help reduce costs in piping construction. It can be used for applications such as high-temperature duct fittings, air conditioning duct fittings, and vibration absorption for blowers. By using a loose flange type, the gas contact parts will be made of the same material, and installation work will also be easier. Due to the ultra-low reaction, the spacing dimensions can be designed to be shorter. The materials used include stainless steel, Hastelloy, Inconel, and others. The thickness ranges from 0.3 to 1.0 mm. For more details, please contact us or refer to the catalog.
