  • Patent number: 9587768
    Abstract: A transportable, recyclable natural gas pipeline is provided. The pipeline has a conduit storage rack. The storage rack has a base plate with a lower surface connected to a I-beam formed skid frame. The skid frame has rows of pipe support rack trestles. The trestles include tiers of upwardly angular lateral pipe support arms. The trestle defines a central pipe line corridor which extends the entirety of the rack. A bulkhead stacking frame is connected to the skid frame at each of the opposite ends and has a central void so that at least one line pipe section is secured to the corridor. A crossing ramp has a pair of generally I-shaped longitudinal rail members. The rail members are capable of being in stacked support, at opposite ends thereof, on the top of the bulk head stacking frame allowing for easy storage, transportation and assembly of a continuous pipeline with a crossing ramp.
