An arrangement for use in adjoining a support structure to a pipe that passes through the support structure. The arrangement comprises a mount attachable to the support structure. Radial bellows are connected to the mount. The bellows are arranged in use to extend circumferentially around a pipe and be connectable thereto such that a volume is defined by the bellows, mount and pipe.

A method of fabricating a conduit comprises steps of attaching a first tubular outboard ply to a first inner collar portion of a first collar with a third weld and attaching the first tubular outboard ply to a second inner collar portion of a second collar with a fifth weld. The method also comprises steps of interconnecting the first inner collar portion and a first outer collar portion of the first collar with a first weld, interconnecting the second inner collar portion and a second outer collar portion of the second collar with a sixth weld, attaching a trimmed first corrugated-inboard-ply end of a corrugated inboard ply to the first outer collar portion with a second weld, attaching a trimmed second corrugated-inboard-ply end of a corrugated inboard ply to the second outer collar portion with a fourth weld, and communicatively coupling a first sensor with an interstitial space.

A pharmaceutical transport system and associated piping and utility panel are presented. The utility panel is received within an opening within a ceiling of a clean room and supported by the ceiling about a perimeter thereof by means of an attached angle member or an integral flange. The use of the angle member or flange accommodates ease of installation. Included as part of the system of the invention are hubs having a bore therethrough that is offset from the axis of the hub itself by an amount ensuring desired angling of the associated transport pipes to accommodate drainage or plumb risers. Also included are bends providing transitions between vertical and sloped horizontal pipes.

Herein a tubular element (2) is disclosed. The tubular element comprises a first tubular portion (4) comprising a first metal or alloy and a second tubular portion (6) comprising a second metal or alloy. At least a portion of an interface (9) between the first and second tubular portions (4, 6) extends within a fixed diameter range along a longitudinal direction (L) of the tubular element. The second tubular portion (6) comprises a first end portion (8) arranged around the first tubular portion (4). The second tubular portion (6) comprises a sealing surface (10) extending circumferentially around the second tubular portion (6) at the first end portion (8).

A method of fabricating a conduit comprises steps of attaching a first tubular-outboard-ply-end of a tubular outboard ply to a first inner collar portion of a first collar with a second weld and attaching a second tubular-outboard-ply end of the tubular outboard ply to a second inner collar portion of a second collar with a fourth weld. The method also comprises steps of inserting a tubular inboard ply into the tubular outboard ply, threadably interconnecting the first inner collar portion and a first outer collar portion of the first collar, and threadably interconnecting the second inner collar portion and a second outer collar portion of the second collar. The method further comprises steps of attaching a corrugated inboard ply to the first outer collar portion with a first weld and attaching a corrugated inboard ply to the second outer collar portion with a third weld.

A method of fabricating a conduit comprises simultaneously corrugating three plies to form a bellows. The method also comprises simultaneously trimming a corrugated inboard ply and a first corrugated outboard ply of the bellows. The method further comprises locating a weld-through ring and a second weld-through ring between the corrugated inboard ply and the first corrugated outboard ply. The method additionally comprises forming a port and a second port through the weld-through ring and the second weld-through ring, respectively. The method also comprises communicatively coupling a sensor and a second sensor with an interstitial space, interposed between the corrugated inboard play and the first corrugated outboard ply, via the port and the second port, respectively.
