Abstract: To provide a gland packing capable of suppressing a fluid from permeating into a packing body or leaking from the packing body through a contact surface between a laminating member and a protrusion of the packing body. The gland packing includes an annular packing body (21) which is formed by winding an expanded graphite tape material in a spiral shape and a laminating member (22) that is bonded to an axial end surface of the packing body (21) and is formed of an annular expanded graphite sheet material, the axial end surface of the packing body (21) being provided with a protrusion (24) facing and contacting an inner peripheral portion or an outer peripheral portion of the laminating member (22) in the radial direction, in which a contact surface (27) between the protrusion (24) and the laminating member (22) is formed so that a radius changes in at least a part in the axial direction.

Abstract: The present invention relates to a filler material (1) for a spiral wound gasket, and to a spiral wound gasket (W) using the fillermaterial (1). The fillermaterial (1) and the spiral wound gasket (W) according to the invention can be applied to various pipe joints and a joint portions of fluid equipments for sealing fluid such as liquid and gaseous body. The filler material (1) of the invention is obtained by removing, by blast treatment, a high density portion on a front surface (2A) or a back surface (2B) of a tape-like expansive graphite tape (2) formed by integrally pressurizing expanded graphite particles. The spiral wound gasket (W) is obtained by overlapping the filler material (1) and a hoop material (5) made of metal band plate with each other and winding them in the form of a spiral. The spiral wound gasket (W) is superior in productivity, and in flexibility, bending property and pliability, and exhibit excellent sealing property even at a low surface pressure.

Abstract: A shaft seal apparatus that exhibits a good and reliable sealing performance, even when a rotating shaft undergoes axial vibration, eccentric revolution, or the like. This shaft seal apparatus has gland packings (2) stuffed in a sealed space (10) formed between a rotating shaft (9) and a stuffing box (1), with gland packings (2) pressed between a first packing gland (3) on a sealed liquid region side (7) and a second packing gland (4) on an atmospheric region side (8). The first packing gland (3) is fixed to a rotary equipment body (6) and the second packing gland (4) is to the stuffing box (1). A screw bolt (15) extending in the axial direction of the rotating shaft (9) is anchored to the first packing gland (3). The stuffing box (1) is provided with a through hole (16) larger than the screw bolt (15) in the flange (1a). The screw bolt (15) running through the through hole (16) has a tightening nut (17) thereon at a place which is out of and backward of the hole (16).

Abstract: A method of producing a spiral wound gasket for sealing fluid such as a liquid including water and oil, and a gaseous body including vapor and gas and a device for producing the spiral wound gasket. The tip portion of a hoop material is cut and raised thereby forming a checking stepped-portion. The checking stepped-portion is caught by a checking pawl, so as to wind the hoop material around a core drum. After winding the hoop material around the outer periphery of the core drum, at least once, the checking pawl is retracted from the outer periphery of the core drum, thereby separating the checking pawl from the checking stepped-portion. The spiral wound gasket produced by the present invention exhibits an excellent sealing property. Moreover, it also has an excellent durability.
