Copper Development Association Inc. is a not-for-profit trade association representing the U.S. copper, brass, and bronze industry, and as such does not sell or distribute product. However, the copper tube that you are looking for can be purchased at any local plumbing, heating or refrigeration supply shop in your area. For contact information of manufacturers of copper tube and fittings, please visit TPF Council page.

The installation of fuel gas systems in Massachusetts is governed by the 248 CMR Massachusetts State Plumbing and Gas Fitting Code in which unlined copper tube is not permitted for natural gas transmission or distribution. Although the code references the allowable use of tin lined copper tube for fuel gas applications. 248CMR also references NFPA 54, which is the National Fuel Gas Code and this code does allow the use of copper tube for fuel gas if the gas supplied contains less than 0.

Any fuel gas lines installed using copper tube must be brazed using a filler metal containing less than 0.05% P (phosphorus) and a melting temperature greater than 1000 degrees F. The only filler metal (trade and industry standard) that contains less than the 0.05% P would be an AWS BAg type alloy (according to the American Welding Society’s AWS A5.8 specification). In no case should solder or “soft-solder” be used to join copper tube and fittings in fuel gas systems.

The fuel gas section of this web site contains design guide information for industry professionals interested in using copper tubing for fuel gas systems. Please check out this information by clicking on the Fuel Gas Design Menu link on the right hand side. Design guides and data sheets are available electronically on the web site or in printed form. Please be sure to check out these and the other information and assistance available from CDA to help you in the use of copper.

CDA has a sizing calculator that simplifies sizing copper tubing for any fuel gas distributions system. Design information is available at our Web site and is also available in publication form. Please be sure to check out these and the other information and assistance available from CDA to help you in the use of copper. If there is anything further we can do, please do not hesitate to email us.

The National Fuel Gas Code (NFPA 54/ANSI Z223.1) and all of the major model building codes have approved copper for the use in fuel gas systems. In fact, in states like Minnesota, Alabama, Georgia, Florida, etc, copper is the dominant, if not the primary choice, for flexible fuel gas piping systems in homes and multi-family units. IAPMO approved copper for use with fuel gas in 1999 - you may want to read the announcement.

Yes, but you should watch the cost of fittings and plastic must be supported every two feet. Do not substitute fittings with Radiantec tubing. If you are using an open system, be sure that the materials are rated potable. All Radiantec polyethylene tubing is highly resistant to nearly everything. The reactivity charts show only a slight reaction to fuming nitric acid (above 1700° F)

For all hobbyists not involved in racing their car, the stock fuel line lengths are just fine. Fuel line length is commonly lengthened by several times the original length in order to prevent a flameout (engine dying) when the car is upside down. Racers sometimes use between 20-30cm (8 to 12 inches) of pressure line between the muffler or pipe and the fuel tank. This line must be wrapped around the fuel tank or another part of the car.

Rigid-wall, nylon tubing, 1/8" or 1/4" outer diameter. Believe it or not, Teflon, while inert, has a relatively high sorption for many compounds. The 1/8" nylon tubing is easier to work with than the 1/4" tubing if soil-gas sampling is your only need. If permeability testing is desired, the 1/4" tubing is better. Stainless-steel tubing is fine for shallow sampling but is logistically more difficult to install as the sampling depth increases (>5'). Flexible tubing (e.g.

The ASTM standards that address the manufacture of the different types of copper tube allowed for fuel gas distribution do not require that the tube carry the ASTM logo or stamp, or standard designation. These standards do outline specific product identification requirements for copper tube made to these standards. This generally includes marking of the tube to include the type of tube (K, L, M, ACR, etc.), name or trademark of the manufacturer, or both, and the country of origin.

Polyimide insulated magnet wire is rated to operate continuously at 240oC (see ‘How is the temperature class for magnet wire determined?’). However, the magnet wire may handle temporary spikes in temperature up to 400oC. Keep in mind that excursions above the rated temperature can shorten the life of any electrical component. Care should be taken not to entrap moisture. If you do wash the wire, make sure it is completely dry before using in production.

Natural sources of copper include nuts, raisins, barley, mushrooms, liver, shellfish, and dried beans.

You can find an index in every December issue of Videomaker that lists, among other things, all of the product reviews we've published during that previous year. The December issue also indexes buyer's guides and feature stories describing entire categories of video products. Our customer service department can help you obtain any back issues containing that issue that you seek.

Yes, there are three basic types of gas cooling systems; absorption, engine-driven and desiccant. In Southern California, the most popular systems are double-effect absorption (either direct-fired or steam) and engine-driven gas cooling units. Absorption cooling systems are similar to vapor compression or mechanical systems in that they utilize a cycle of evaporation and condensation of a fluid or refrigerant to produce cooling.

this time the emergence of Bioheat® fuel is much too new for burner manufacturers to comment on. However, in work accomplished throughout the northeast, organizations like Carlin, Beckett and Power Flame (notable burner manufactures) all are reviewing Bioheat® fuel. Bioheat® fuel appears to have little or no negative impact on a burner’s performance while providing emissions, sulfur, lubricity, global warming and health benefits.

The reason copper tubing should not be used is most likely related to ability of the copper tube to absorb moisture molecules. The finish of the copper tube is such that it will absorb / desorb moisture continually and it cannot be successfully purged. Please switch to stainless steel tubing.

Natural Gas decreases our reliance on foreign fuel sources (97% of the natural gas used in the US comes from North America)

Pretty much like you fuel a car or truck. The fueling station and dispenser looks about the same as a “normal” station. The nozzle and receptacle are a bit different but an NGV is just as easy to fuel and fuels up in about the same amount of time.
