What is PE pipe in natural gas?
Polyethylene (PE) gas piping is the most widely used plastic piping material for the distribution of natural gas. PE has a well-documented inertness to both the external soil environment and to natural gas.
Which would be the most common joining method for SDR 11 PE piping in the gas distribution industry?
Butt Fusion The most widely used method for joining individual lengths of PE pipe and pipe to PE fittings is by heat fusion of the pipe butt ends as illustrated in Figure 1. This technique produces a permanent, economical and flow-efficient connection.
What does PE pipe stand for?
Polyethylene
Polyethylene (PE) is a thermoplastic material produced from the polymerization of ethylene. PE plastic pipe is manufactured by extrusion in sizes ranging from ½” to 63″. PE is available in rolled coils of various lengths or in straight lengths up to 40 feet.
Is PE gas pipe UV resistant?
PE4710 pipe exhibits resistance to many chemicals and solvents, including those commonly found in the natural gas distribution system. WL Plastics yellow stripe PE4710 pipe offers class leading UV resistance allowing long term storage in the most demanding environments. Light material weight.
Are gas unions directional?
No. In some applications, it is common to flow from the nut side to the external thread side, but this is not required. There are also applications where it may make sense to flow the other direction.
Can I use Teflon tape for gas fittings?
Teflon tape for gas fittings, also known as gas-rated Teflon tape, is yellow in color and clearly states it is for gas lines and connections. The tape works on all gas line types, including butane, propane and natural gas lines.
What is PE gas line?
Polyethylene gas pipes are the preferred natural gas distri- bution piping product of choice with over 90% usage in North America today. Polyethylene gas pipes are light- weight, non-corrosive, available in coil lengths, and easy to install by heat fusion or mechanical fittings.
Can you splice a natural gas line?
Yes you can (and fortunately for you, there is a union right there to make your work easier.) Replacing the this joint is easy enough, but remember you are working with gas. Professionals are recommended and required in some places, as are permits.
How does a PE gas pipe fitting work?
Compression-style PE pipe fittings – work in a manner similar to most compression type fittings in the plumbing & heating industry. They utilize a compression ring, ferrule and nut to create a leak-proof connection. PE gas pipe fittings we sell are compression style.
What are the different types of PE fittings?
Types of fittings and connection systems for PE gas pipe 1 Butt fusion (incl. 2 Socket fusion – heat is applied both to the fitting and the pipe surface (separately), until both reach desired temperature and start melting. 3 Electrofusion (EF) – utilizes electricity to fuse the fitting (made of conductive material) and the pipe together.
What is the difference between HDPE and MDPE gas pipe?
MDPE gas pipe is yellow in color, while HDPE pipe can be black, black with yellow stripe or black with a yellow outmost layer. All types of fittings used for PE pipe fall into (2) distinct categories – mechanical fittings and fusion fittings.
What’s the maximum pressure of a PE pipe?
Maximum Capacity of PE Pipe in Cubic Feet per Hour with a Gas Pressure of 2.0 psi and a Pressure Drop of 1.0 psi (based on a 0.60 specific gravity gas) 1,000 BTUh = 1 CFH Maximum Capacity of PE Pipe in Cubic Feet per Hour with a Gas Pressure of 5.0 psi and a Pressure Drop of 3.5 psi
