gas pipe

The gas pipe is bonded by the connection of the gas appliance to the EGC run with it's circuit conductors. Nothing further is required. I had at one time installed a jumper from the water pipe to the gas pipe at the water heater only to have the inspector remove it with a screw driver.
 
Here's the article Rob is refering to if you need it.

250.104 Bonding of Piping Systems and Exposed Structural Steel.

(B) Other Metal Piping. Where installed in or attached to a building or structure, a metal piping system(s), including gas piping, that is likely to become energized shall be bonded to the service equipment enclosure, the grounded conductor at the service, the grounding electrode conductor where of sufficient size, or the one or more grounding electrodes used. The bonding jumper(s) shall be sized in accordance with 250.122, using the rating of the circuit that is likely to energize the piping system(s). The equipment grounding conductor for the circuit that is likely to energize the piping shall be permitted to serve as the bonding means. The points of attachment of the bonding jumper(s) shall be accessible.
FPN: Bonding all piping and metal air ducts within the premises will provide additional safety.

Normal gas piping per NEC 250.104(B). CSST is another story - yellow stuff = #6 Bond - Black "CounterStrike" by Omegaflex is required to be bonded with #6 if the date code is prior to 0731. 0731 and later is not required to be bonded as stated by Manufacturer.
refer to http://www.omegaflex.com/trac/litlibrary/FGP-554.pdf - hope it is ok to post this link.
In summary, CSST depends on the manufacturer. Just bond per the specifications they list. I guess the gas companies will have to provide documentation for each install.

Hope this helps.

This is from the counter strike specs.

No special bonding is required.

3. There are no special installation requirements for CounterStrike date coded 0731 and higher. The bonding requirements for CounterStrike are per National Electrical Code NFPA 70 Article 250.104 and the National Fuel Gas
Code NFPA 54. No additional bonding is required.

Dennis, You are correct. I was just trying to emphasis that the older Counterstrike requires a #6 bond. I don't know if there is any old stock out there, but you never know. The requirement to bond the old stock Counterstrike was also listed in the original lawsuit agreement. As far as I know, only the new 0731 Counterstrike is exempt from the #6 bond. Are you aware of any other manufacturers that have "non bond" CSST?
 
Jim the old yellow stuff is not called counter strike. I think this is why I was confused. The black CSST is called counterstrike and I am not aware of other products like this. I talked to the omegaflex tech support a month or so ago about this product. No bond necessary but I bonded it anyway.

In terms of the #6 bond on the old CSST. I would not say that since I have read different requirements from different manufacturers. If I am going to bond the old CSST I am going to do it according to 250.66. A 400 amp service will get a #2 and a 200 amp service will get a #4.

Read page 71 of this document Omegaflex

It references bonding the yellow jacketed CSST according to 250.66.
 
Yeah, I hate the stuff. Gas guys love it because it is so easy to bend, etc. To bond or not to bond????....The applications are very confusing. Regardless, the gas pipe manufacturers/gas installers are responsible for it. If they install it, they must be responsible to determine if it gets bonded or not. If they find themselves in another class action, they will have to support the removal of the bonding. It would be nice if rather than date code, they would cover it in another color sheath to readily distinguish the new stuff. That would be too simple....

They did. The new counter strike Trac pipe is black in color. The older CSST is yellow. Not everyone is buying the black stuff yet. I had one heating contractor use it.
 
Reading CMP-5's responses to the proposals regarding CSST, it is quite clear that the NEC does not, and does intend, any special bonding provisions. Obviously I can't speak to New Jersey's opinions on the matter, however.
 
In article 103 it requires the installer to follow the manufacturers listed instructions. After considerable time speaking with UL they do not have a listed electrical instruction manual for how to bond CSST. There is simply the opinion of the companies engineer that has his reasons for how he thinks it should be bonded.

The state interpretation allows the gas piping to be bonded according to the most likely circuit to energize the piping.
 
Omegaflex makes both yellow trac pipe and the black counterstrike pipe. Gastite is also another manufacturer (yellow). I was under the impression that OMegaflex had previously made counterstrike csst and made a manufacturing change to it, thus the date code arrangement. With different manufacturers, date codes, and all of the other changes, It would seem that the gas installers should have to provide documentation for each install dictating manufacturers bond or not requirement.
