    Tube Protection

    The WVT Breiding protective shell/protection shields

    Protect your tube system (superheaters/economizer) with resistible and easy-to-install cast iron protective shells.

    • Heat resistance up to 1,100° Celsius due to special chromium-nickel alloy quotas
    • Straight length 300 mm and 400 mm
    • Diameters standardized to mm: 31.8, 33.7, 38.0, 42.4, 44.5, 48.3, 51, 57, 60.3
    • Individual angles, shapes and solutions are possible.

    Cast iron shells have numerous advantages compared to common, short-lived shells:

    • Lower assembly effort
    • No specially qualified professionals needed
    • No welding
    • Extended service life
    • Risk of standstills caused by tube leakages minimized

    Due to the decreased risk of damages within the initial warranty period, Breiding shells are especially used by plant constructors (OEMs).

    We adapt the alloy quotas to the special needs of biomass plants and waste incineration plants.

    Ears (or straps) ask for biomass plants can be bended in cold state to the tubes. Other combustion systems have even higher requirements (e.g. caused by fuel or content of flue gas) to the shells. Thus, the material is even more sophisticated and needs to be heated to cherry red before bending the ears to the tubes. The assembly to the tube system is possible both in the boiler or in the workshop.

    The cranked shells connect perfectly to each other due to a collar, tongue-and-groove system. The ears lead to a form lock fixing to the tubes. The bending of the ears can be done by using a pipe wrench or by tapping with a hammer. To fasten the installation we have developed a special mounting tool (hydraulic plier). This tool enables the maintenance team to bend the ears to the tubes without much effort. The reduced installation time and the easy assembly result in enormous time savings.

    How to mount protective shells in cast iron (Breiding patent)

    Sicromal shells

    The low-cost execution for less-exposed areas of superheaters/evaporators.

    With our special tools we are able to produce straight type shells up to 1,000 mm length. Cranked shells with collar can be produced up to 2,000 mm in straight type.

    Individual shapes are possible.

    Materials

    • Sicromal 8 (1.4713)
    • Sicromal 10 (1.4742)
    • Sicromal 12 (1.4762)
    • 15 Mo 3 (1.5415)
    • Special materials according to customer needs

    When using sicromal shells please bear in mind that the shells have already experienced an excessive production process that weakens the surface. The sheets need to be cut, heated and pressed in cold state into the desired shape. In this process, micro cracks arise, which become weak points in operational use. A practical example: Think about a paper clip – the bending radius is the weakest point.
