  • Wearflex® Telescopic Seals

    The main function of Wearflex® Telescopic Seals is to prevent access of cold air ingress inside a radiation area saving you high energy costs. Wearflex® telescopic seals are applied in the (petro)chemical industry where catalyst tubes in reformers penetrate the roof. These telescopic seals are easy to install around each reformer tube at the pigtail connection and on top of the roof.

    Thermal Pipe expansion

    Within a reformer temperatures can reach up to 950°C. Causing pipe sections to expand as a result, pipes move uncontrollably. These seals will keep the pipes insulated while the pipes can still move around in axial patterns (100-350mm).

    Every operational process is different, that is why every Wearflex® Telescopic Seal is tailor-made for your specific process. These seals are made out of a combination of alloyed steel parts with half pipe sections, which slide into each other like a telescope, it is made in combination with state-of-the-art insulation blankets and board. The mount of our Wearflex® telescopic seals takes only 5-10 minutes, using a screwdriver and stainless steel jubilee clips.

    Advantages

    Prevent cold air ingress
    Can absorb extreme axial movements
    Decrease heat loss and therefore reduce energy costs
    Easy to install and remove
    Temperature resistant up to 900°C

    Pigtail mattresses

    Together with our Wearflex® telescopic seals we can offer you the Wearflex® insulation cover (pigtail mattresses) to cover the pig tale tubes from the manifold to the catalyst tube. These mattresses are specially designed to insulate the pig tale tubes. They can be installed quickly in comparison with the traditional calcium silicate pipe insulation with aluminium foil and tie-wire. They can be removed quickly as well, for inspection or maintenance of the pigtail tubes.
