■ Features - DMTflex’s Hot-flex expansion joint system is an engineered product that was specifically designed to provide high pressuretemperature transfer containment of highly corrosive medias that could not be safely handled by conventional metallic, elastomeric or Teflon expansion joint. Dmtflex’s Hot-flex combines the high pressure rating of a metallic expansion joint with the high temperature corrosion resistance of Teflon, creating a product that will outperform them both, Engineering data shown is just a sample of Dmtflex’s Hot-flex capabilities. Each hot-flex expansion joint can be custom engineered to your specific application: pressuretemperature rating, spring rate movement (axial, lateral and angular) metallic carcass (stainless steel, monel, Inconel, hasteloy, etc.) various length. ■ Operating Temperature Range - ‘-10℃ up to +250℃’

■ Features - DMTflex composite-type flexible elements consist of multiple layer of high temperature fabrics, thermal insulation and an external cover of materials dictated by the operating conditions and external atmosphere around the expansion joint location. The addition of a PFE film laminated fiberglass vapor barrier and extra rein-forcing piles are also incorporated in this construction if there is a cycling of the flue gas through the dew point. ■ Structure - Multi-layer expansion joint - Outer cover material - Gas sealing foil - Temperature-resistant fabrics - Insulating materials

"expansion joint enterprise specializing in manufacturing" dmt co. Ltd is thermal expansion that is generated in industry system various md have been used in order to prevent fatigue takire or the pm due to vlora-t an as a company that specie:2es in ma-luta:luring expansion joint pipe.

Such as teflon expansion joint it offers a total solution to construction. ■ features - dmtflex’s flexible joint are used steam, air, gases, water and oils. ■ operating temperature range - max 220℃’

■ Features - DMTflex’s Teflon expansion joint are used primarily in fluid conducting systems as resilient connections and tremor barriers. They are designed to compensate for mis-alignment, to absorb expansion and contraction and to isolate vibration and shock. They are also frequently used to reduce stress on fragile mating flange. ■ Application - Air conditioning, heating and ventilating systems in industrial buildings, hospitals, hotels and on board ships central and ancillary power generating stations in industrial building, factories, ships and off-shore sewage disposal and water treatment plant, pumps, etc. Process piping in pulp and paper manufacture. ■ Operating temperature range - ‘-40℃ up to +220℃’ ■ Types of material - Neoprene(CR), EPDM, Hypalon(CSM), Viton(FKM), Nitrile(NBR), Buthyl(TH)

■ Features - Externally pressurized type expansion joint is advanced product as a result of research activities about the transmission part of high pressure steam and high temperature water. It is more excellent that more economical than Internally Pressurized expansion joint and widely used in an advanced country. Especially, it is evaluated as a suitable product for construction gas fired combined cycle power plant. ■ Application - Steam, hot water, warm water, and other pipelines. ■ Pressure - 0.2MPa to 1.5 MPa

■ features - control ring type expansion joint has structure that inserted ring to make every bellows work equally and reinforced intensity of bellows internal pressure to endure high pressure ■ application - hot water, high pressure steam, oil, and other pipelines ■ pressure - 0.2mpa to 20 mpa.
