 Containment Piping
Systems
Increasing concerns about the environment have prompted governments around the world to create guidelines to protect the environment from industrial pollution. Many regulations provide penalties for owners, managers and employees for environmental damage caused by waste water leaks and chemical spills. These problems intensify when leaks from piping failures result in damage to equipment, the environment and/or cause harm to people. Choosing the right containment piping material therefore,
requires a thorough knowledge of the physical features of various
plastics and other piping materials like concrete and metal.
What is Containment Piping?
Containment piping is any pipe liner or lining used to prevent leakage or infiltration in pipes and piping systems. There are many different types of containment piping. Traditional pipe liners and pipe lining systems are sleeves, casings, or supports that are inserted along the length of the pipe. To prevent underground and above ground piping systems from leaking, many are starting to believe that secondary containment piping is the best way to go.
Advantages of Hdpe Containment Piping
It is inevitable that pipes and tanks will leak. Surrounding them with a shell to contain the leak not only protects the environment, it extends the life of a piping system by decades. Containment piping, whether it be in the form of protective liners and/or lining systems, are made from a variety of materials. Examples include everything from glass and metal to rubber and plastic. High density polyethylene (HDPE) provides excellent wear, low friction and high toughness.
Hdpe containment pipe does not corrode. Its flexible enough so that ground movement from swelling and shrinking soil and even earthquakes will not damage it or cause joints to leak. It has a smooth interior so that less energy is required to pump water through it than for concrete or steel. It can be heat fused or mechanically joined to make leak tight joints that will last the life of the pipe. Several methods are presently being used to replace steel, concrete and cast iron pipe with hdpe pipe without digging the trenches that disrupt traffic and make a mess.
Hdpe containment piping has one other advantage over other piping materials. Because of its flexibility and strength, hdpe pipe can be installed using trenchless technologies from slipling to pipe bursting. These methods not only reduce the cost of repairing a leaking pipe, but eliminate the need for expensive excavation and surface repair.
To satisfy government standards, installations of containment piping are required to meet the following specifications:
- Density - ASTM D-1505
- Melt Index - ASTM D-1238
- Flex Modulus - ASTM D-790
- Tensile Strength at Yield - ASTM D-638
- ESCR - Environmental Stress Crack Resistance - ASTM D-1693
- Hydrostatic Design Basis - ASTM D-2837
- ESCR - Compressed Ring - ASTM F-1248
- Cell Classification - ASTM D-3350; PE 345434C
Applications for Containment Piping
Containment piping can be used to control, contain and transport a variety of corrosive fluids and fumes from industrial and commercial applications.
- sanitary containment pipe
- landfill leachate and condensate piping
- water main maintenance
- wastewater drainage
- agriculture drainage
- chemical piping containment
