What does PE 4710 mean?
What does PE 4710 mean?
PE4710, for example, means that the product is made of polyethylene with a “4” rated density, “7” rated slow crack growth class, and has a 1,000-psi maximum recommended HDS with a 0.63 design factor at 23 degrees Celsius in accordance with ASTM D3350 and the stress rating policies in the Plastics Pipe Institute’s PPI- …
What does PE3408 mean?
PE3408. PE3408 has a resin designation of 3, a crack resistance factor of 4, and a HDS of 800 psi at 73F. Because this classification has been in existence for quite some time, it is sometimes included in specifications even when another pipe is actually being used, such as PE3408/3608 or PE3408/4710.
What is black pipe with yellow stripes used for?
A critical purpose of this color code for solid wall pipe and conduit is to identify the intended end-use application of fuel gas (methane or propane) piping. This color code provides standardization for solid yellow or black with yellow stripe plastic pipe used in fuel gas applications.
What kind of pipe is black with yellow stripes?
Yellowstripe® 8300 series PE piping is defined as a Code C material and as such contains a minimum of 2-3 percent carbon black. Black (ASTM D3350 Code C) gas pipe materials are considered stabilized against UV degradation for unprotected outdoor exposure of at least 10 years per ASTM D2513.
Is PE4710 a HDPE?
PE 4710 pipe is produced from the highest rated HDPE pipe materials. This is a long lasting, fusible pipe. PE4710 pipe is a pressure rated product and listed under the Plastics Pipe Institutes (PPI) Technical Report Four (TR-4 @www.plasticpipe.org > PPI Publications > Technical Reports).
What does SDR 17 mean?
SDR is defined as the ratio of the nominal outside diameter to the nominal wall thickness. It is common to use the SDR as a method of pressure rating pipes. Therefore a higher SDR indicates a thinner-walled pipe at any given diameter. Common SDR’s are : 7.4, 9, 11, 13.6, and 17. Stefan Dreckötter.
What is black PE pipe?
Black polyethylene, or PE, pipe comes in very long rolls and is used in many areas for the water main between the meter and the house and for sprinkler systems. Just like any other type of pipe, poly pipe does not last forever and can develop leaks with time and with the help of tree roots.
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.
What are orange pipes used for?
Other uniform color codes by the American Public Works Association for identifying utility conduits include red for electric power lines, cables, conduit and lighting cables; yellow for gas, oil, steam, petroleum or gaseous materials; and orange for communication, alarm or signal lines, cables or conduit.
What is c906 pipe?
JM Eagle’s high-performance high-density polyethylene water pressure pipes are suitable for municipal and industrial transmission systems for potable water, sewer, drain, mining, irrigation, and reclaimed water. …
What is the difference between HDPE 3408 and HDPE 4710 pipes?
HDPE 4710 pipes with superior ductility, resistance to fracture, and increased performance characteristics allow higher internal pressures than HDPE 3408 without reducing service life. The increase in pressure rating is due to several factors. HDPE 4710 has significantly higher requirements for test data quality, analysis, and substantiation.
What is the life expectancy of HDPE 4710 pipes?
These characteristics ensure that HDPE 4710 pipes are conservatively rated for a 100 year design life when properly designed, installed and operated. Slow crack growth, or SCG, is the long-term failure mode for PE pressure piping materials.
What is the pressure and surge allowance for a 4710?
HDPE 4710 has a 2 times pressure rating for occasional surge events and a 1.5 times pressure rating for recurring surge events. To learn more about pressure and surge allowance see our WL118 Pressure Ratings document.
What is the pressure rating for 12 inch HDPE pipe?
The calculation yields 128 psi, but US Federal Regulations limit the pressure rating to 125 psi for 12” IPS and smaller pipes (100 psi max for >12” IPS through 24” IPS.) 4. Determine the long-term pressure rating for DR 11 WL Plastics HDPE pipe on the surface transporting compressed air at 120°F.
