Name: KRHD steel flexible pipe connectors
Features:
steel flexible pipe joints, also known as clamps, steel flexible joints, steel flexible joints, expansion joints off style, fittings. Steel flexible pipe joint is a pipe connection, reliable, easy to install products. At low pressure by the elastic deformation ring, to seal the purpose; the pressure increases, the role of the ring through the media, and play the role of self-sealing, and the gap left between the pipe end to compensate for thermal expansion due to the cold pipe reduction resulting from the displacement and deflection.
Installation instructions:
steel flexible pipe fittings to be installed before the pressure plate bolts loose, pull the product to the installation length, then tighten the diagonal method, not partial pressure such as overhead use, shall be installed at both ends of the corresponding mounting bracket . Flange connection using GB4216.3-4126.5 standard. Other specifications can be used as production.
