三和テック List of Products and Services

The "bellows" is a product primarily composed of a body, ring flange, and bands. The tension of the fabric of the body (such as nylon tarpaulin) is utilized to insert the ring. The wire diameter of the ring is determined by the inner and outer diameters of the product, and the material of the body is decided based on its intended use. Additionally, the shape is flexible, and it can be produced in cylindrical, oval, square, rectangular, and tapered forms. 【Features】 - The hardness of the coating material can be freely selected. - It alleviates concentrated stress on the material after molding, preventing internal shear. - There is almost no heat generation and heat retention inside the rubber due to alternating stress. - There is no variation in the strong elongation curve in vertical, horizontal, and diagonal directions (fabric). - Since it is molded after vulcanization (post-processing), it can be produced in any desired shape. *For more details, please refer to the related links or feel free to contact us.

"Fledact(R)" is completely different from conventional metal joints, and it is used in various industries for purposes such as absorbing the expansion and contraction of duct piping due to heat and insulating vibrations from fans by utilizing its elasticity. Conventional metal expansion joints have a small displacement capacity, making it difficult to absorb large deviations in other directions, and they have weaknesses such as inability to withstand chemical resistance. Non-metallic expansion joints are products that solve the shortcomings of metal expansion joints. 【Features】 ■ Excellent sealing, heat resistance, and expansion performance ■ Lightweight and easy to handle compared to metal bellows ■ Unlike metal bellows, the structure is not fixed, allowing for various uses according to fluid conditions and duct structures ■ Smaller reaction force compared to metal bellows, and can easily absorb large expansions, axial differences, angles, or twists, among others *For more details, please download the PDF or contact us.
