A hose clamp or hose clip is a device used to attach and seal a hose onto a fitting such as a barb or nipple. Screw clamps consist of a galvanized or stainless steel band into which a screw thread pattern has been cut or pressed. One end of the band contains a captive screw. The clamp is put around the hose or tube to be connected, with the loose end being fed into a narrow space between the band and model ship building clamps 3dm captive screw.

When the screw is turned, it acts as a worm drive pulling the threads of the band, causing the band to tighten around the model ship building clamps 3dm or when screwed the Model Ship Building Plank Clamps Table opposite direction, to loosen. Pairs of screw clamps on a short rubber tube form a "no-hub band," often used for attaching sections of domestic wastewater piping, or used for other pipes as a flexible coupler to fix alignment difficulties or to prevent pipe breakage due model ship building clamps 3dm relative movement of sections or an emergency repair.

They can also be used in a similar way, as a simple means for the transmission of small amounts of power. A short length of hose is clipped between two shafts where vibration or variations in alignment may be taken up by the flexibility of the hose. This technique is well adapted to use for mock-ups in a development laboratory.

The company owns the trademark for Jubilee Clip. A similar type model ship building clamps 3dm clamp to the screw band, also with a solid screw, is the Marman clamp.

Spring clamps are typically made from a strip of spring steelcut so that model ship building clamps 3dm side has a narrow protrusion centered on the end, and the other side a pair of narrow protrusions on either. The ends of these protrusions are 3dmm bent outwards, and the strip 3dmm to form a ring, with the protruding tabs intermeshing.

To use the clamp, the exposed tabs are pressed towards each other typically using pliersincreasing the diameter of the ring, and the clamp is slid onto the hose, past the portion that will go onto the barb.

The hose is then fit onto the barb, the clamp expanded again, slid onto the portion of the hose over the barb, then released, compressing the hose onto the barb. Clamps of this design are rarely used builidng high pressures or large hoses, as they would require unwieldy amounts of steel to generate enough clamping force, and be impossible to work with using just hand tools. They are commonly used on automotive cooling system hoses several inches in diameter, for example on most model ship building clamps 3dm Volkswagen automobiles.

Spring clamps are particularly suited for confined or otherwise awkward places where other clip types would require tightening tools applied from narrow and possibly inaccessible angles. This buildingg made them particularly popular for applications such as automotive engine bays and for securing barb connections in PC water-cooling.

Wire clamps consist of a piece of heavy wiretypically steel, first bent into a tight U, then formed into a ring shape with one end overlapping the other, and finally the ends bent outwards and cut.

A captive nut is attached to one end, and a captive screw to the. When the screw is tightened, the overlapped ends of the wire are pushed apart, tightening the wire loop around the hose.

For an explanation of why this design is used, see the section on sealing the connection. The clamp is placed over the end of the hose or tube to be connected and when each ear is closed at the base of the ear with a special pincer tool, it permanently deforms, pulling the band, and causing the band to tighten around the hose. The size of clamp should be chosen such that the ear s are almost completely closed on installation.

Some such clamps feature dimples intended to provide a spring effect when the diameter model ship building clamps 3dm the hose or tube contracts or expands due to thermal or mechanical effects. A stepless type of ear clamp was invented by Hans Oetiker in Horgen, Switzerland, which eliminates steps or gaps on the inner circumference of the clamp. Such stepless clamps are claimed to be well suited to applications involving thin-walled hoses, model ship building clamps 3dm with higher retained loads.

This suggests buidling should be considered for difficult to seal applications such as vuilding plastics or other less malleable materials, commonly used in the automotive industry. However, these devices are not typically referred to as hose clamps. Hose clamps are typically limited d3m moderate pressures, such as those found in automotive and home applications.

At high pressures, especially with large hose sizes, the clamp would have to be unwieldy to be able to withstand the forces expanding it without allowing the hose to slide off the barb or a leak to form. For these model ship building clamps 3dm pressure applications, compression fittings, thick crimp fittings, or other designs are normally used. Hose clamps are frequently used for things other than their intended use, and are often used as modeo more permanent version of duct tape wherever a tightening band model ship building clamps 3dm something would be useful.

The screw band type model ship building clamps 3dm particular is very strong, and is used for non-plumbing modwl far more than the other types. These clamps can be found doing everything from mounting signs to holding together emergency or otherwise home repairs.

Another handy attribute: worm-drive hose clamps can be daisy-chained or "siamesed" to make a long clamp, if you have several, shorter than the job requires. Some things seen assembled with hose clamps include the tail boom on a GMP Cricket model helicoptera homemade gas scootermakeshift pipe hangers, mounts for rooftop TV and shortwave antennas, and virtually every imaginable automobile body component.

One of the fundamental goals of most hose clamps is to ensure a tight seal between the hose and the barb, preventing the working fluid from escaping. To this goal, they are designed to provide even pressure on all sides, with no gaps.

An example of this would be wire clamps. An obvious design would seem to be simply having a wire around the hose, one end attached to a nut, whip the other end to the screw, and when moxel, pulling the ends of buklding wire towards each. However, this will leave a gap where no pressure is applied underneath the screwand cause a leak. To combat this, the more complicated and weaker design of having the ends overlap and then be pushed apart from each model ship building clamps 3dm is used, as this ensures pressure around the entire 3d, of the hose.

To ensure a good seal, the barb, mocel nipple, or beaded tube must be smooth and model ship building clamps 3dm of nicks, scratches, or contamination. Stuck hoses should never be removed by slitting them, as this can leave a scratch on the fitting which will cause a leak. The other goal of a hose clamp is to provide mechanical attachment keeping the hose attached to a barb, hose nipple, or tube.

To do this the clamp is typically placed on the hose behind the first ramp of the barb or behind the raised area near the end of and completely around the circumference of the hose nipple or tube called a bead. If the hose were to slide the clamp would have to expand to fit over the barb or raised bead. This keeps the hose attached to the barb, hose nipple, or beaded tube. Within the United States, Model ship building clamps 3dm International maintains Specification J [1] for thirty-two different hose clamp designs, including screw, spring, and t-bolt styles.

It also maintains Specification J [2] for the testing the sealing of hoses. There is a list of all authors in Wikipedia. Login Email Address. Sign In. Remember Me. Forgot Password? Top Links. Social Share.

First of all, the Professional Building Slip caters to hulls up to cm in length, so will obviously take in many of the larger kits in our hobby, plus those impressive POF scratch builds we aspire to. If your ship's stem and stern were strong enough you could adjust the fore and aft clamps to work on the deck for instance. Hobby tools Australia sell them.
