摘要： PROBLEM TO BE SOLVED: To uniformly reinforce the whole region of a fluoroplastic sheet by a fabric reinforcing material by uniformly extending the stitches of the reinforcing material sheet so as to follow the fluoroplastic sheet without damaging and wrinkling the reinforcing material sheet at the time of molding by setting the angle, which is formed by the warp or weft yarns of the fabric reinforcing material of a composite sheet and at least one side of a square mold, to 30-60° when the composite sheet, which is formed by superposing the fluoroplastic sheet and the fabric reinforcing material one upon another to integrate them is press-molded by the mold.
SOLUTION: In this deep-draw molded product for an expansion joint comprising the composite sheet formed by superposing the fluoroplastic sheet and the fabric reinforcing material one upon another to integrate them, the angle, which is formed by the warp or weft yarns of the fabric reinforcing material of a composite sheet and at least one side of a square mold, is set to 30-60° to press-mold the composite sheet under heating to integrate the same to manufacture the deep-draw molded product. The stitches of the fabric reinforcing material extend by pressure/heating molding to follow the extension of the fluoroplastic sheet.

摘要： PROBLEM TO BE SOLVED: To provide an expansion joint capable of preventing bellows from being damaged over a long term even if internal pressure repeatedly changes made. SOLUTION: A bellows 41 of an expansion joint 31, of the whole comprises a fluorocarbon resin layer placed at the inside in the radial direction and a glass fabric layer placed at the outside in the radial direction, includes a pair of sections-to-be fixed 51 and a bellows body section 53 formed so as to expose between them. Furthermore, the bellows body section includes a pair of base sections 55 and a tube-shape swelling section 57 which is placed between them, swells out of a virtual surface with a curvature that includes the pair of base sections and swells in an arc shape. Threads of the glass fabric layer have density that warps and wefts are respectively in the range of 6 to 10 and set in an area of 25 millimeters square, and such a fiber direction that each of warps and wefts slant relative to the axial center of the bellows.

摘要： PROBLEM TO BE SOLVED: To provide an expansion joint capable of preventing bellows from being acutely recessed even when internal pressure caused by circulating fluid is applied. SOLUTION: The expansion joint 31 comprises a pair of joint bodies 37 and 39 provided corresponding to a pair of ducts 103 and 105, and a bellows 41 to connect the pair of joint bodies. The bellows comprises a pair of fixed parts 51 to be fixed to the pair of joint bodies, and a bellows body part 53 which is located between the pair of fixed parts and exposed from the pair of joint bodies. The peripheral length of the bellows body part is maintained to be larger than the peripheral length of the pair of fixed parts by 2-15% when internal pressure is not applied to the bellows mounted on the pair of joint bodies.
