A clamp assembly has a clamp with a clamp band and a clamping device for clamping the clamping band and has a heat protection device with a housing and at least one insulating layer. The housing has a respective wall at each axial end face, the wall being divided into sections and protruding radially inwards, and the at least one insulating layer can be positioned between the walls of the housing. The clamp can be surrounded at least in some regions by the housing and/or the at least one insulating layer of the heat protection device, and the heat protection device is designed to be connectable to the clamp.

A clamp includes a housing, a band, and an actuating member. The housing defines and first slot and has a surface from which a first locking feature extends outwardly. The band has a first portion secured to the housing and a second portion extending within the first slot of the housing. The actuating member is seated at the housing and has a surface interfacing with the first locking feature. A plurality of mating features each extend outwardly from the surface of the actuating member and the plurality of mating features are spaced about a circumference of the surface of the actuating member. The actuating member is configured, when actuated, to move the second portion of the band relative to the housing. The first locking feature is configured to consecutively engage one of the plurality of mating features when the actuating member is actuated.

A duct coupling apparatus includes a collar portion having a first end and a second end, a flange disposed about the collar portion in a manner that divides the collar portion into an first side and a second side, and a retaining structure extending from a surface of the flange towards the second side of the collar portion. The retaining structure and the collar portion define therebetween an annular region for receipt of a sealing element, such as an o-ring or gasket. The retaining structure prevents the sealing element from extruding outwards and/or failing when under pressure.

A retention device for attaching an insulation element to a V band clamp or to another device for connecting pipe ends. The retention device includes closure elements that cooperate to permit the outer and/or inner circumference of the retention device to be decreased. The retention device further includes a bendable belt segment that may be placed about an insulation element as part of an outer covering or like a type of outer covering.

The present invention relates to a soil pipe coupler that includes a body portion formed from a thermoplastic elastomer. The body portion includes an inner wall, an outer wall, and a first and second lip defined by the outer wall. The first lip is disposed proximate a first end, while a second lip is disposed proximate a longitudinally-opposed second end of the body portion. The body portion includes an annular seat and at least one rib member that extend radially inwards from the inner wall and further defines a channel extending from the first to the second end. The soil pipe coupler includes a sheathing member configured to wrap about the body portion and is disposed between the first and second lips. Additionally, the soil pipe coupler includes at least one clamp configured to operably engage the sheathing member. An associated method of installation is also provided.

A coupling for a tube includes an attachment and a housing. The attachment is attached to the tube and has a barrel-shaped exterior surface. The housing contains the barrel-shaped exterior surface such that the attachment is rotatable in the housing while not being removable from the housing. The coupling thereby allows easy rotation of the tube within the coupling. The coupling may be utilized to attach the tube to another tube or to another structure.

A high-strength ferritic stainless steel for clamp includes, in percent (%) by weight of the entire composition, C: 0.04 to 0.1%, Si: 0.2 to 0.6%, Mn: 0.01 to 1.5%, Cr: 14.0 to 18.0%, Al: 0.005 to 0.2%, V: 0.005 to 0.2%, N: 0.02 to 0.1%, the remainder of iron (Fe) and other inevitable impurities, and satisfies following formulas (1) and (2), and the number of precipitates with an average diameter of 0.5 μm or less is 2.5×10.sup.6 pieces/mid or more: (1) 0.35%≤Si+Al+V≤0.6% and (2) 0.09%≤C+N≤0.12%.

The present invention relates to a multipurpose hose clamp. The hose clamp is capable of rotating laterally in a 360-degree orientation in clockwise and counterclockwise directions. The multipurpose clamp includes a round, flat, thin, single-gear band, and a clamping device. The clamping device or screw cage is separable from the band. A screw is configured to twist or turn into the clamping device and engages the slots disposed on the band to increase or decrease a diameter of the hose clamp. The multipurpose clamp can be applied to any type of hose, for example, water hoses, automobile hoses, radiator hoses, air vent hoses, etc. The screw cage is designed to rotate 360-degrees in either clockwise or counterclockwise directions.
