Abstract

The invention relates to a preparation method of a seamless high-pressure gas cylinder. The preparation method comprises the following steps of 1, preparing a blank; 2, extruding the blank reversely to machine a rough tube blank; 3, carrying out precision forging and tube drawing to form a precision forging tube blank; 4, carrying out heat treatment on the precision forging tube blank; 5, carryingout spinning to prepare a tube, reducting the thickness of the tube blank subjected to precision forging to a required thickness by thickness reduction spinning equipment, forming the tube, and preparing annular reinforcing ribs integrally formed with the tube on the inner wall of the tube through spinning; and 6, sealing the opening by hot spinning, and preparing the gas cylinder. The inventionfurther relates to the seamless high-pressure gas cylinder prepared by the method, the inner wall of the gas cylinder is provided with the integrally-formed annular reinforcing ribs, so that the pressure-bearing capacity of the tube is improved, and the tube is attractive in appearance and easy to install; and materials are saved, the cost is low.

Description

technical field

[0001] The invention relates to a preparation method of a gas cylinder and the gas cylinder, in particular to a preparation method of a seamless high-pressure gas cylinder and the gas cylinder. Background technique

[0002] Titanium and titanium alloys are widely used in aviation, aerospace, navigation, petroleum, chemical, medical and other fields due to their excellent comprehensive properties such as low density, high specific strength, high temperature resistance, corrosion resistance, non-magnetic properties, and good biocompatibility. Applications. In the past, high-pressure gas cylinders for submarines were made of steel. With the advancement of technology, titanium alloys began to enter the field of gas cylinders for submarines due to their special advantages. The new generation of titanium alloy gas cylinders for submarines has put forward higher requirements in terms of performance and capacity. , it is required to meet the pressure design requirem...
