Problems solved by technology

The cost of stainless steel is quite high, and despite its corrosion-resistant properties, it is not well suited for use in seaborne vehicles - seagoing ships have a load-carrying limit based on their buoyancy, and a good portion of a ship's load-carrying capacity is taken up by it The physical weight, or its "empty weight", takes up
[0004] Also, on marine vehicles, the unavoidable splash of salty sea water can cause annoying and lengthy electrochemical coupling between the stainless steel of the pressure vessel and the carbon steel of the hull structure
This coupling leads to so-called marine corrosion, which in the long run will deteriorate the properties of the higher potential difference or more electronegative metal

Embodiment Construction

[0080] 1. The corrosion resistant metal lining is made of AISI 316 stainless steel with a tensile strength of at least 500 MPa and a carbon content of less than or equal to 0.08%, which is clad with a tensile strength of 3,200 MPa or greater and preferably Carbon fiber-based structural composites with a Young's modulus of 230 GPa or higher, each yarn of carbon fibers advantageously containing 12,000, 24,000 or 48,000 filaments, and for thermal insulation considerations, the outer second layer is made of tensile The tensile strength is at least 80MPa, and the heat transfer coefficient is about 0.2W·m -1 ·K -1 Made of non-reinforced epoxy resin.

[0081] 2. The corrosion-resistant metal lining is made of AISI 316 stainless steel with a tensile strength of at least 500 MPa and a carbon content of less than or equal to 0.08%, which is clad with a tensile strength of 3,200 MPa or greater and preferably Carbon fiber-based structural composites with a Young's modulus of 230 GPa or ...

Abstract

The present invention relates to a pressure vessel for containing or transporting pressurized gas. More particularly it relates to such vessels for containing or transporting compressed natural gas. The present invention also relates to a method of storing or transporting gas onshore or offshore. Moreover, the present invention relates to a vehicle for transporting gas, in particular compressed natural gas.

Description

field of invention [0001] This invention relates to pressure vessels for containing or transporting pressurized gas, and more particularly to such containers for containing or transporting compressed natural gas (CNG). [0002] The invention also relates to a method of storing or transporting gas on land or at sea. Furthermore, the invention relates to a vehicle for transporting gas, especially compressed natural gas. Background of the invention [0003] Conventional pressure vessels used to hold or transport pressurized gases are usually made of stainless steel and thus heavy. The cost of stainless steel is quite high, and despite its corrosion-resistant properties, it is not well suited for use in seaborne vehicles - seagoing ships have a load-carrying limit based on their buoyancy, and a good portion of a ship's load-carrying capacity is taken up by it The physical weight of the car is taken up by its "empty weight". [0004] Also, on marine vehicles, the unavoidable s...
