A fitting apparatus for connecting pipes according to the present invention includes a fitting unit which includes a first body into which a first pipe is inserted and a second body which is connected to the first body to form a pipe insertion space therein together with the first body and into which a second pipe is inserted, wherein in the first body and the second body, a first recessed groove and a second recessed groove spaced apart inward from the first recessed groove are formed along an inner circumferential surface thereof, respectively, a compression member which is provided in the first recessed groove to compress and fix the first pipe or the second pipe, and a sealing member which is provided in the second recessed groove to maintain airtightness between the fitting unit and the first pipe or between the fitting unit and the second pipe.

Clamp insulation systems and methods are disclosed. An example clamp system includes a foil cover having a top surface with a support structure, side walls and tapered end walls. The foil cover can define a pocket between the top surface, side walls and end walls. The insulation system further includes an insulation layer disposed in the pocket between the sidewalls and adjacent an inside of the top surface. The side walls can have a depth so that the pocket is capable of receiving a band of a clamp and so that the side walls are capable of being crimped about the band of the clamp.

[Problem] To provide a pipe joint allowing reliable connection to a pipe P without flaring.

[Means of solving problem] The pipe joint includes a flare joint body 1F, a cap nut 2, and a stop ring 3. A curved pressure-contacting slope surface 32 of the stop ring 3 contacts a slope surface 5 with reduced-diameter tip of the flare joint body 1F under pressure to establish sealing by means of mutual contact between metallic surfaces. The pipe P is grasped in a tightly pressure-contacting state using a back tooth and a front tooth formed at a tip head 37 of a substantially cylindrical thin part 35 of the stop ring 3.

A connecting device for a sealed exchange of fluid between two components is disclosed. The connecting devices comprises a pipe portion with at least two pipe portion ends, wherein an extent of the pipe portion between the pipe portion ends determines a streamline of the fluid, and comprises a sealing element which at least partially surrounds the pipe portion. At least one of the pipe portion ends is configured to form an inflow and/or outflow region that extends over the clear dimension of the at least one pipe portion end.

A tool for removing a coating from an end of a coated conduit comprising a metallic conduit having an outer diameter and a polymeric material applied over the outer diameter thereof is provided. The tool comprises: a guide member having an outer diameter sized to fit within an internal diameter of the metallic conduit; and a cylindrical cutting member having a substantially closed first end rotatably connected to an arbor, a substantially open second end, and a plurality of teeth elements. The cylindrical cutting member has an inner diameter that is substantially equal to the outer diameter of the metallic conduit such that when the cylindrical cutting member is rotated, the teeth elements remove the polymeric material from the outer diameter of the metallic conduit.
