  Product advantages:

  Flange adaptor & coupling are commonly used in civil water supply and drainage pipelines, chemical pipelines, ship pipeline systems, oil pipelines, etc. In the pipeline system, the gland type expansion joint can be axially twisted and contracted within a certain range, and the expansion and contraction can reach 150△L. Mainly prevent equipment resonance, pipeline medium change, building structure foundation settlement, geological disasters cause torsional displacement, lateral misalignment, angular misalignment, axial compression and other hazards, thus protecting the pipeline system can be safely operated, especially suitable for vibration or certain The slope and the connection in the curved pipe.
  Advantages: large expansion and contraction, easy installation and long service life (long service life of 10-30 years).

  Application:

  Flange adaptor & couplings are used to transport seawater, fresh water, hot and cold water, drinking water, domestic sewage, crude oil, fuel oil, lubricating oil, refined oil, air, gas, steam and granular powder with a temperature not higher than 250 degrees. Such as media.
  Flange adaptor & coupling makes the connection of the pipe simple, fast, safe and reliable.

  Performance:

  Flange adaptor & couplinghas reasonable structural design and reliable sealing performance: the sockets are connected at both ends, and the installation and disassemble are simple. It is suitable for connecting steel pipes, cast iron pipes, ductile iron pipes, PVC pipes, ABS pipes, etc., which transport water, oil, gas and granular powder. It can compensate the axial displacement and deflection of the pipe within a certain range while connecting pipes. eccentric.

  Product elements:

  After flange adaptor & coupling is installed on the pipeline, the elastic sealing ring of the nut is tightened, and under the action of the nut gland, the inclination is mutually inclined, and the outer ring of the pipe is tightly sealed and connected. When the temperature changes, the pipe can freely expand and contract in the middle of the joint, the local foundation sinks, the pipe can be deflected, and the seal is ensured to have no leakage, thereby automatically compensating.

INSTALLATION INSTRUCTIONS

1. The appropriate model must be selected according to the working pressure, connection method, medium and compensation amount of the pipeline.
2. Adjust the installation length of the two ends of the product and the flange during installation. Tighten the pressure bolt evenly at the diagonal to make it a whole, and have a certain amount of displacement. When it is convenient for installation and maintenance, adjust according to the site size. The axial thrust can be transmitted to the entire pipe.
3. When the pipeline generates instantaneous pressure and is greater than the working pressure, it should use a joint higher than the working pressure.
4. When the displacement of the pipeline is greater than or equal to the amount of compensation of the joint, the amount of water in the joint should be increased to parallel displacement. It is strictly forbidden to adjust the tolerance of the pipeline so that the joint is in the limit displacement and deviation state, and it is not allowed to exceed the limit. , displacement, deflection, etc.).
