HDPE pipe is a type of flexible plastic pipe used to transfer fluids and gases.It is often employed for replacing aging concrete or steel main pipelines.Constructed from the thermoplastic HDPE (high-density polyethylene), it has low permeability and robust molecular bonding, making it suitable for high-pressure pipelines.
Plastic Pipe lengths manufactured in Australia by extruding HDPE material.. Plastic pipe is a tubular section, or hollow cylinder, made of plastic.It is usually, but not necessarily, of circular cross-section, used mainly to convey substances which can flow—liquids and gases (fluids), slurries, powders and masses of small solids.
Plastic is the generic name for a family of synthetic materials derived from petrochemicals. It is often product of two or more components. It is often product of two or more components. There are many families of plastics and polymers being used in construction industry, such as acrylics , composites , expanded polystyrene , polycarbonates ...
CLSM as a highway construction material is becoming more widespread throughout the United States.Data received from questionnaires sent by the Pennsylvania Department of Transportation in 1991 and the Transportation Research Board (TRB) in 1992 indicated that approximately 30 states had some experience with the use of flowable fill, and at least 24 states have a specification for flowable fill.
CPVC can withstand corrosive water at temperatures greater than PVC, typically greater by 40–50 °C (greater by 72–90 °F), contributing to its popularity as a material for water-piping systems in residential and commercial construction. CPVC maximal operating temperature peaks at 200 °F (93 °C).
Plastic tubing, such as PVC and CPVC, for plumbing applications also has different sizing standards [vague]. Agricultural applications use PIP sizes, which stands for Plastic Irrigation Pipe. PIP comes in pressure ratings of 22 psi (150 kPa), 50 psi (340 kPa), 80 psi (550 kPa), 100 psi (690 kPa), and 125 psi (860 kPa) and is generally available ...

Polyurethane is a thermosetting plastic with no solvents, with a three-dimensionally linked molecular structure giving it mechanical stability. The polyurethane lining used for internal coating has the following standard properties is standardised by EN 15655:2009 (Ductile iron pipes, fittings and accessories – Internal polyurethane lining ...
