Peripheral sealing gland for elongate objects passing through a surface or beyond a pipe end

A peripheral sealing gland configured to form a seal, between an elongate member and a substantially flat surface having an aperture into which the elongate member extends, the peripheral sealing gland comprising:

• an at least in part frustoconical shaped skirt through which the elongate member is to pass and defining, at an upper periphery of the skirt, a deformable upper seal configured to deform about and form a first seal to a periphery of the elongate member;
• a flange having an inner surface and an outer surface, the flange integrally formed with the skirt and depending from a lower periphery of the skirt, the flange having two or more concentrically arranged endless lip seals extending from the inner surface, and a plurality of flange apertures;
• a ring configured to bear on the outer surface of the flange, so as to apply a first pressure to the two or more endless lip seals to form a second seal against the flat surface when the ring is fastened to the substantially flat surface by fasteners to capture the flange therebetween, the ring having a plurality of ring apertures corresponding to, and co-locatable with, at least some of the flange apertures to receive the fasteners;
• a resealable split extending from the upper seal of the skirt to a peripheral edge of the flange;
• continuous upstands depending outwards from the skirt on each of a first side of the resealable split and a second side of the resealable split, the continuous upstands running along the entire length of the resealable split;
• and
• a compression clamp comprising:
• at least a first connection member and a second connection member;
• a first rail coupled to both the first connection member and the second connection member and configured to continuously extend along a first external surface of the first side of the resealable split between the first connection member and the second connection member;
• and
• a second rail coupled to both the first connection member and the second connection member and configured to continuously extend along a second external surface of the second side of the resealable split between the first connection member and the second connection member;
• wherein the first rail applies a second pressure to seal the resealable split;
• wherein the second rail applies a third pressure to seal the resealable split;
• and
• wherein the first side of the resealable split opposes the second side the resealable split.

• an at least in part frustoconical shaped skirt through which the elongate member is to pass and defining at an upper periphery of the skirt, a deformable upper seal configured to deform about and form a first seal to a periphery of the elongate member,
• a flange integrally formed with the skirt and having an outer surface and an inner surface, the flange depending from a lower periphery of the skirt, the flange including two or more concentrically arranged endless lip seals extending from the inner surface, and having a plurality of flange apertures disposed entirely between consecutive ones of the endless lip seals;
• a ring having a plurality of ring apertures, the ring apertures corresponding to, and co-locatable with, at least some of the flange apertures, the ring able to bear on the outer surface of the flange, so as to apply a first pressure to the endless lip seals to form a second seal against the flat surface when the ring is fastened to the substantially flat surface by fasteners to capture the flange therebetween;
• and
• a resealable split extending from the upper seal to a peripheral edge of the flange;
• the skirt having, toward the flange, a retention flange forming a circumferential pocket to removably receive the ring and to permit adjustment of the ring relative to the flange to co-locate the flange apertures with the ring apertures;
• wherein a diameter of the flange apertures is smaller than a diameter of the ring apertures, so that the flange is configured to form, at the flange apertures, a third seal against the fasteners;
• a compression clamp configured to close the resealable split to form a first seal, the compression clamp comprising:
• at least a first connection member and a second connection member;
• a first rail coupled to both the first connection member and the second connection member and configured to continuously extend along a first external surface of a first side of the resealable split between the first connection member and the second connection member;
• and
• a second rail coupled to both the first connection member and the second connection member and configured to continuously extend along a second external surface of a second side of the resealable split between the first connection member and the second connection member;
• wherein the first rail applies a second pressure to seal the resealable split;
• wherein the second rail applies a third pressure to seal the resealable split;
• and
• wherein the first side of the resealable split opposes the second side of the resealable split.
