          Land Liquid Loading Arm


          The land liquid loading arm (loading arm) is composed of rotating joints with good rotating flexibility and sealing performance and pipes, and it is a device used between the tank car and the trestle storage and transportation lines for the transmission of liquid medium.
          The key parts, i.e. rotating joints, are processed by precision numerically-controlled machine tools and they have the supporting structure with build-in double raceway, which rotates flexibly and is light and reliable. The outer ring adopts alloy steel while the inner ring adopts stainless steel or PTFE liner so as to ensure that the device can safely and reliably apply to high-temperature, low-temperature or highly-corrosive medium.
          The sealing ring adopts reinforced PTFE, and the lining stainless steel elastic supporting ring and sealing are polished, having excellent self-lubrication property and corrosion resistance.

           Composition of structure

           Product features

          • The double-raceway rotating joints and the sealing rings having elastic clamp ensure the medium will not leak during loading;
          • The spring cylinder balancer equipped with neutral equilibrium makes the loading arm to be operated in a convenient and labor-saving way;
          • During the loading, it moves along with the tank within the normal moving range of tank;
          • When the loading arm is recovered, it is locked in the direction in parallel with the travelling direction of tank, occupying small space;
          • With rational structure, the smallest arm size can meet the most reasonable envelope scope.
