Title:
HYDROGEN AND NATURAL GAS MIXED ENERGY TRANSMISSION PIPELINE AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/137968
Kind Code:
A1
Abstract:
Disclosed are a hydrogen and natural gas mixed energy transmission pipeline and a preparation method therefor. The transmission pipeline sequentially comprises, from inside to outside, a hydrogen transmission layer, a first barrier layer, a first protective layer, a reinforcing layer, a second protective layer, a natural gas transport layer, a second barrier layer, and a third protective layer; support bars are provided in the natural gas transport layer; the support bars are used for maintaining the shape of a transport cavity of the natural gas transport layer; the width of the support bars is 5-7 mm; the ratio of the number of support bars to the inner diameter of a pipe of the natural gas transport layer is 1:15; the unit of the inner diameter is mm, the number of support bars is an integer; the thickness of the support bars is consistent with the thickness of the cavity of the natural gas transport layer; the support bars are helical. The pipeline of the present invention can transport hydrogen and natural gas in a mixed manner, so that transmission efficiency and simplicity are improved, the service life is long, and high-pressure transmission is met.
