Elbow

       Steel pipe fittings + rigid polyurethane foam insulation layer + high density polyethylene outer pipe steel casing external protection, internal insulation treatment. According to the compensation amount of the elbow in the pipeline design, the diameter of the outer casing should be increased accordingly to ensure that there is enough insulation thickness at the elbow after expansion and deformation, and the insulation material should be changed accordingly, and the high resilience soft insulation material should be selected.

        Insulation elbow is also made into insulation prefabricated parts in prefabrication plant.
