H.T.H.'s metallic flexible pipes with parallel ondulation, without gaskets and seam, guarantee perfect tight of pressure and also very high flexibility, assured by the deformation of continuos section.
Our pipes are provided, in function of operating conditions, of one or more metallic braid, to resist to the bottom boost caused by internal pressure.
Our pipes are designed conformly ISO 10380.
