How is polyethylene pipe classified?
Polyethylene plastic pipe compounds are classified according to density, melt index, flexural modulus, tensile strength at yield, environmental stress crack resistance, hydrostatic design basis at 23° C (73.4° F), color and ultraviolet stabilizers.
What is ASTM D3350?
ASTM standard D3350 covers the identification of PE pipe and fitting materials in accordance with a cell classification system. Cell classification is based on tests of primary properties including density, melt index, flexural modulus and more.
What is ASTM d3035?
This specification covers polyethylene (PE) pipes made in thermoplastic pipe dimension ratios based on outside diameter, and pressure rated for water. All pipes produced under this specification may be used for the transport of water, industrial process liquids, effluents, slurries, municipal sewage, etc.
What is ASTM F714?
ASTM F714, 2022 Edition, May 1, 2022 – Standard Specification for Polyethylene (PE) Plastic Pipe (DR-PR) Based on Outside Diameter. This specification covers polyethylene (PE) pipe made in three standard outside diameter sizing systems, based on outside diameters of DIPS 3, IPS 4, Metric 90 mm and larger.
What does SDR 9 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.
What is ASTM F2160?
ASTM F2160, Standard Specification for Solid Wall High Density Polyethylene (HDPE) Conduit Based on Controlled Outside Diameter (OD) is applicable to coilable HDPE conduit, duct and innerduct for the protection of fiber optic and power cables.
What is PE4710?
High-performance polyethylene is an improved polyethylene compound for pressure pipe that is designated PE4710. Compared to conventional pressure piping materials such as PE3408, several important performance characteristics are significantly enhanced.
Is SDR 11 thicker than SDR 17?
The strength is greater for the lower SDR value that represents thicker pipe wall thickness; making SDR 11 stronger than SDR 17.
What is ASTM D2239?
ASTM D2239 : Standard Specification for Polyethylene (PE) Plastic Pipe (SIDR-PR) Based on Controlled Inside Diameter.
What is NEMA TC7?
NEMA TC7 | Dura-Line. FuturePath. Product Comparison Tool Digital Tools and Calculators. Dura-Line manufactures standard High Density Polyethylene (HDPE) conduits for standard installation applications such as standard underground, as innerducts in existing conduits, or corrugated products to use in congested areas.
How thick is SDR 26?
While SDR-26 wall thickness ranges from 0.173-0.775 with 4.500 inches (4-inch size), 6.625 inches for 6-inch, 8.625 inches for 8-inch size, 10.750 inches for the 10-inch size, 12.750 for the 12-inch length, and 18.673 for the 18-inch size.
What does PE3408 mean?
Pipe made of high density polyethylene — such as PE3408 and PE3608 — is used mainly in industrial and municipal applications such as water mains or sewer and storm drains. This kind of pipe must bear up under both high pressure from within and the weight of the earth from above when buried deeply in a trench.
