Embodiment 1

[0117] Prepare a double-head ultra-large ultra-high-pressure gas cylinder liner with a diameter of 779mm, a length of 12m, and a wall thickness of 8mm. The rated pressure of the ultra-high-pressure gas cylinder is required to be 50Mpa, specifically including the following steps:

[0118] S1, the preparation of aluminum alloy liner spinning tube, this step specifically includes the following steps:

[0119] S1a, the spinning forming of the straight section 3 of the aluminum alloy liner spinning tube, the seamless tube with a length of 1.6m is used for 4 times of spinning by the tension three-wheel staggered forward spinning method, and the spinning process is 2m The long floating mandrel is assisted by spinning; the stagger amount in the tension three-wheel staggered forward spinning method is set to 6mm; thus the spinning part A is obtained. The spinning part A is a straight tube of equal thickness or a straight tube section 3 with outer circumferential end frames at both ends...

Abstract

The invention provides a double-end-end ultra-large-size ultrahigh-pressure gas cylinder liner and a manufacturing method thereof. The double-end-seal ultra-large-size ultrahigh-pressure gas cylinderliner comprises a straight cylinder section, a seal head A and a seal head B, wherein the seal head A and the seal head B are positioned at the two ends of the straight cylinder section respectively,a bottle opening A and a bottle opening B are located on the sealing head A and the sealing head B respectively; the inner container of the ultrahigh-pressure gas cylinder is an aluminum alloy inner container with the length of 5-13 m, the nominal outer diameter of the straight cylinder section ranges from phi 300-phi 850 mm, and the rated pressure of the ultrahigh-pressure gas cylinder ranges from 35-70 Mpa. According to the double-end-end ultra-large-size ultrahigh-pressure gas cylinder liner and the manufacturing method thereof, the spinning processing method is adopted, the whole product is free of weld joints, the preparation process is simple, the operation is convenient, the energy consumption is low, the pollution is small, the loss of raw materials is less, and the raw material cost is saved; the double-end-seal ultra-large-size ultrahigh-pressure gas cylinder liner and the manufacturing method has the characteristics of being large in size, high in reliability and thin in wall, and light in weight; and the inner material structure is uniform and compact, the overall strength effect is excellent, and the double-end-seal ultra-large-size ultrahigh-pressure gas cylinder liner has the high-pressure-resistant characteristic and has important significance in the manufacturing of the ultrahigh-pressure gas cylinder.

Description

technical field [0001] The invention belongs to the technical field of high-pressure containers, and in particular relates to an inner liner of a super-large-sized ultra-high-pressure gas cylinder with double heads and a manufacturing method thereof. Background technique [0002] Ultra-high pressure gas cylinders have been widely used in various industries of the national economy such as industrial and mining production, construction, transportation, ocean, aviation, medical treatment, and military affairs. The capacity of the ultra-high pressure gas cylinder, the thickness of the bottle wall, the manufacturing process and materials will all affect the performance of the ultra-high pressure gas cylinder. For example, natural gas and hydrogen are clean energy sources that are developed and widely used worldwide. At present, the storage and transportation of 35-70MP ultra-high pressure gas cylinders and the use of compressed natural gas (CNG), compressed hydrogen and other co...
