シー・エス・エム List of Products and Services

CSM Corporation optimally selects the characteristics of both metals and non-metals to meet various needs such as low reaction, large expansion and contraction, corrosion resistance, wear resistance, weather resistance, and vibration resistance. The "Technical Data 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, basic dimensions of flanges, and more. For more details, please contact us or refer to our catalog.

• Water and sewerage pipe fittings

Non-metallic flexible pipe joints have a very flexible and pliable nature that cannot be achieved with metal. 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 exceeding 1000°C, thanks to special coating materials and composites. We offer high-temperature duct flexible joints, dust covers, flexible shoots and ducts, vibration-absorbing bellows, pipe expansion joints, special heat-resistant expansion joints, and special corrosion-resistant expansion joints, among others. For more details, please contact us or refer to our catalog.

• Water and sewerage pipe fittings
• Interior construction
• Crane and others

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 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, thereby achieving a longer lifespan for the bellows.

• Water Treatment
• Interior construction
• Insulation work

The ultra-low reaction bellows made of metal expansion joints 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 work. It can be used for applications such as high-temperature duct joints, air conditioning duct joints, and vibration absorption for blowers. By using a loose flange type, the gas connection part will be made of the same material. Additionally, installation work becomes 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.
