LINER FOR CHEMICAL CYLINDER AND METHOD OF MANUFACTURING THE SAME

PROBLEM TO BE SOLVED: To provide a liner for chemical cylinders the pressure resistance of which is improved as compared with a conventional one. SOLUTION: The liner is formed with a drum 2 which is opened at its both ends, and end plates 3, 4 which are joined to both the ends of the drum 2 so as to close the openings at both the ends of the drum 2. The drum 2 comprises a tubular drum main body 5 which is opened at its both ends, and a reinforcement member 6 which is fitted in the drum main body 5 in such a manner that its both ends project outward from both the ends of the drum main body 5. The reinforcement member 6 comprises a tubular part 7 in close contact with an inner peripheral surface of the drum main body 5 and a plurality of partition sections 8 which are fixedly arranged in the tubular part 7 and divide the interior of the tubular part 7 into a plurality of spaces. Both the end plates 3, 4 are fitted on the outward-projecting portions 6a of the reinforcement member 6. The drum main body 5, the reinforcement member 6 and the end plates 3, 4 are joined to one another at the contact portions of the drum main body 5 and the end plates 3, 4. COPYRIGHT: (C)2005,JPO&NCIPI
