	Convolutely lined and wrapped composite tubes - Patent 4900383
		The wrapping material is then wrapped at least once around the tubular structure before anchoring the wrapping material to the tubular structure near the second end of the wrapping material using the same or a similar adhesive composition that was used to anchor the first end of the wrapping material to the tubular structure.
		Tubes that are advantageously lined by the method of the present invention include those that are generally formed by wrapping a tubing precursor material around a support, such as a mandrel, that has a shape consistent with the desired shape of the hollow interior of the tube.
		1 and 2 and the tubing precursor material 110'.

		The tubing material can have any desired diameter and wall thickness; although, when a low heat conductive material is used, the thinner the wall thickness the better the heat transfer into and out of the phase change material.
		After the tubing material is crimped, it is fed to the cutting station where the tubing is cut in the middle of the crimp area, forming individual pellets.
		For example, when glass is used as the tubing material, the compression and crimping steps are preferably performed in a single operation, with the seal being formed by the compression of the molten glass in the seal area.

	Texture enhancement of metallic tubing material having a hexagonal close-packed crystal structure - Patent 4765174 (Site not responding. Last check: 2007-10-11)
		A method of producing tubing composed of material, such as zirconium and alloys thereof, having a hexagonal close-packed crystal structure is provided which increases the radial texture or orientation of basal poles in the crystal structure of the material.
		Thus, the deformation pattern produced during metalworking of tubing is usually characterized by the Q ratio, the ratio of the radial (due to wall reduction) to circumferential (due to diameter reduction) deformations produced during pilgering.
		An increase in radial orientation of basal poles is an increase in the texture of the tubing material.

	ColeParmer-UK Technical Library
		Tubing is an essential part of a peristaltic pump; however, end-users too often unknowingly select a tubing formulation that is unsuitable for their applications.
		Typical pump tubing materials have working pressure ratings ranging from about 10 pounds per square inch (psi) to 40 psi, with softer materials such as silicone at the low end of the range and firmer materials such as Norprene® toward the high end.
		Tubing manufactured to meet very close dimensional tolerances often is measured as it is being extruded to ensure it remains within the specified dimensions.

	Que es el coiled tubing? - What is Coiled Tubing?
		Upon its manufacturing, the tubing is rolled onto large spools with core diameters ranging from 8 – 12 feet.
		It is fabricated in a variety of material grades, characterized by minimum monotonic yield strengths of 60, 70, 80, 90, 100, 110 and 120 ksi.
		Coiled tubing is used for a wide range of oil field services, including but not limited to drilling, logging, cleanouts, fracturing, cementing, underreaming, fishing, completion and production.

	The Bend Tooling Encyclopedia, L-N (Site not responding. Last check: 2007-10-11)
		The line of tangency is distinguished from the point of bend in that the point of bend is region of material on both sides of the line of tangency that becomes plasticized under the force of the bending process.
		This ensures that the vertical cross-section of the arc of the tube bend, while it is in a plastic state, will take the shape of the nose as the tubing material is drawn over it.
		This plastic region of the tube bend extends both behind and ahead of the line of the tangency, therefore, the mandrel nose must be set forward of the line of tangency into the arc of the tube bend in almost all cases.

	Laboratory Tubing
		In addition to it's use as a part of a peristaltic pump flexible tubing is often used for a variety of purposes in a laboratory.
		Vinyl tubing should not be used with organic solvents; the plasticizers dissolved in the vinyl will tend to migrate into the solvent and the tubing will become brittle with time.
		Unlike vinyl tubing, there is no plasticizer dissolved in the tubing material; the tubing is pure polymerized silicones with nothing to leach out.

	Applications: Automotive - Copper-Nickel Automotive Vehicle Brake Tubing
		Brake system tubing is vulnerable to the pressures of air or fluid flowing through it, to corrosion from road mud and salt, and to damage of any protective coatings on its surfaces from stone pecking where it is exposed under the chassis.
		The introduction of steel tubing was coincidental with salting of roads as a means of clearing ice and snow and in anticipation of icy conditions.
		For tubes covered with a moist, salty mudpack for six months, brazed steel was severely corroded resulting in perforation of the tubing wall; whereas, only superficial general corrosion was found on the copper-nickel tubing.

	(Cover Story- Extrusion) Coextrusion: Changing the Face of Tubing (MDDI archive, Sep 05)
		Coextruded tubing is often made with one or more thin layers, or skins, on the inside or outside of the tube.
		Sometimes the chosen materials are not from the same family, such as vinyl and polyethylene.
		Tubes with physical properties that mimic standard commodity products can be coextruded with skins of new formulations to offer low coefficients of friction, static dissipation, and antithrombogenic properties in a tube that otherwise appears to be indistinguishable from other standard tubing.

	The Bend Tooling Encyclopedia, A-B (Site not responding. Last check: 2007-10-11)
		Aluminum-bronze is preferred over alloy steel as the material for perishable tooling to bend carbon steel, stainless steel, titanium, and nickel alloy tubing because it tends to break down into fine particles instead of galling (i.e., welding relatively large pieces of itself) to the tubing as it wears.
		When specifying a tube bend, it is necessary to state from which reference point the magnitude of the radius is determined.
		This increased flow is necessary only for tubing materials that do not become readily plastic at the point of bend or when wall thinning of the extrados must be kept to an extreme minimum.

	Selecting a Replacement Polymeric Device Material (MPB archive, Sep 96)
		The PVC material, however, was run under different conditions--melt temperature lower by 100°F, higher pull speed--and had a tendency to stick to the uncoated areas of the screw.
		In this table, the higher the number, the better the property is. Although the stiffness of the COPA tubing as extruded ranked higher than the control (1.22 versus 1.00), at 0.96 it was close to the control tubing's stiffness after a 160-minute exposure to body-temperature saline solution.
		Although the PVC tubing exhibited the best ink adhesion properties, and the vendor stated that the material could be recompounded to match the required stiffness, PVC was dropped from the material candidate list at this time because of its very high stiffness ranking and poor heat stability.

		Chemicals that have no effect on the tubing at room temperature could attack the tubing at elevated temperatures.
		Pump tubing manufacturers should be able to supply test data to support their tubing life claims.
		Silicone generally is the most gas-permeable material, and thermoplastic materials tend to be relatively impermeable.

	(Cover) Finding Tube Materials that Make the Grade (MDDI archive, Jan 05)
		For example, the tubing in an intravenous fluid administration set “has to be cheap and as clear as possible so you can see the drug going through it,” he says.
		Bonding for the material is also difficult, he adds, though a number of new products have been introduced for better bonding to nonsilicone substrates.
		In Jennings’ opinion, the key to selecting the best material for a tubing application is for design engineers to work closely with the tube manufacturer in the early stages of the project.

	P-122U Polymeric Flexible Hose and Tubing Markets (Site not responding. Last check: 2007-10-11)
		A tube is usually defined as a long cylindrical body with a hollow center, used to convey fluids, and a hose is generally considered to be a flexible tube.
		However, we differentiate hose and tubing by also considering tubing to be a simpler product constructed from a single material, while hose is a more complex structure that usually consists of three layers: the tube itself at the center, some type of external reinforcement, and a protective covering material of some type.
		This study is an update of a 1998 BCC study of flexible hose and tubing materials and their markets, in which we bring up to date the state of the industry and BCC’s estimates and forecasts for U.S. markets for base year 2003 and forecast year 2008.
