There are currently only two legal forms of piping that can be used in an underground operation. Currently, underground gas piping goods comply Code If it is embedded in a tube, CSST or corrugated stainless steel tubing may be used underground. But, because of the higher cost of the stainless steel material and of the fittings and extra labour, CSST for most underground gas piping applications can not be used.

Polyethylene tubing is the most popular and economical material used for underground piping. For the use of natural or propanic gas, the correct polyethylene tube is colored yellow.
Even if the polypipe is versatile, its drawbacks are very real and it is important not to plug the pipe inside a ditch or to place underground fittings under unnecessary stress. The ditch must be as straight as possible. If curves and corners are necessary, dig them as wide a diameter as possible to ensure that the polyethylene pipe is not subjected to excessive pressure. We also tell customers to place a garden panel in a circle of twelve meters in contrast. The circle of 12-foot diameter reflects the peak corner radius for an operation of underground gas piping using polypipes.
During the length of the drain, the underground piping of polyethylene shall remain at least 18 inches lower than level. A hardened anodised steel raise is used on both ends of the ditch to move regular npt pipe threads from polyethylene tubing 2 above the ground. Such risers represent a large part of the overall product costs of underground gas piping. The polyethylene tubing is relatively low per foot, but anodized gas rises can be a bit expensive, depending on the diameter of the tubing. In particular, the gas rises are a tube 7 to 8 feet long and bent in l form. You can not in any way shorten or change them. Thus the last seven-8 inches of the two ends of the ditch should be digged further down after the 18 in the minimum at 22-24 in which the gas rises above the surface unnecessarily. We also suggest that the last few meters of the two ends of the ditch be dug straight away, so that the gas fitting located at the end of the riser underground will not exert undue pressure. The best choice is the polyethylene tubing. This will not only never be corroded or rusty, it is also durable and will make your piping issue safe and stable throughout the lifespan of your home when you move from the soil, for example, due to an earthquake.
The tracer string, don't forget! You should mount a yellow solid core wire throughout the whole ditch length and keep the wire on at least one end of the ditch above ground level. The tracking wire is how to locate and code the location of the subterranean gas piping in the future. We usually leave excess tracer wire so that there is no risk that it will be lost unintentionally. You can "pretty it" once the whole project is done as long as it remains accessible overground.Top Searches - Trending Searches - New Articles - Top Articles - Trending Articles - Featured Articles - Top Members
