Polywrap is a polyethylene encasement product available in a variety of sizes, from four-inch to 42-inch diameter. It’s a versatile solution for protecting pipes. Its benefits include ensuring that water cannot leak into the pipes and is ideal for water systems.
V-Bio Enhanced Polyethylene Encasement
The V-Bio Enhanced Polyethylene Pipe Encasement is a three-layer co-extruded film that protects the pipe from corrosion by inhibiting the growth of bacteria and anaerobic cells. The material is designed to meet or exceed AWWA and ASTM standards for corrosion protection.
Since its introduction in 1958, polyethylene pipe encasement has protected millions of feet of ductile iron pipe from corrosion. This corrosion-control solution is both durable and economical. Standard polyethylene encasement depletes oxygen from the water under the wrap, which reduces the corrosion rate. In addition, V-Bio ™ encasement contains corrosion inhibitors and biocide additives to help ensure the long service life of ductile iron pipe.
V-Bio Enhanced Polyethylene Pipe Encasement (r) is a new addition to this corrosion-control technology. The product contains an antimicrobial additive on the inside surface. The additive also serves as a volatile corrosion inhibitor, inhibiting the growth of corrosion cells. It is compatible with bare pipe and zinc-coated ductile iron pipe. It meets or exceeds AWWA and American National Standards Institute polyethylene encasement standards.
Black polyethylene pipe
Polyethylene pipe encasement is a material that is used to protect cast iron pipes from rust, corrosion, and other corrosive elements. It is a relatively inexpensive material to produce. It is effective against corrosion and offers great protection for cast iron pipes in highly corrosive environments. In 1972, ANSI/AWWA adopted a national standard for polyethylene encasement.
The benefits of polyethylene pipe encasement over other corrosion-control methods are many. It is easy to install and requires little monitoring. It also does not degrade while underground. It also offers great value and is an excellent choice for a variety of applications. Its high level of corrosion protection makes it the most cost-effective corrosion protection material.
Polyethylene pipe encasement is available in a variety of thicknesses. For instance, a low-density polyethylene film is required to be 0.008 inches thick, while a high-density film is required to be 0.004 inches thick. In addition, installation methods are consistent with AWWA C105.
The polyethylene should completely encase the pipe and provide a watertight corrosion barrier. To ensure a seamless and water-tight fit, you can use wax tape or moldable sealant to seal voids under the polyethylene sheet. You may need to apply two layers of the polyethylene sheet. Overlap each adjacent pipe by at least one foot. This slack will allow backfill to be placed around the fitting without tearing the polyethylene sheet.
If you are going to use a polyethylene pipe encasement for your plumbing system, there are several steps you must follow. First, clean the pipe before installing it. Next, tape the end of the polyethylene to the end of the existing pipe. Make sure to overlap the two pieces by at least two feet. Finally, backfill the pipe with sand within one foot of the polyethylene encasement.
Choosing polyethylene encasement for your piping system has several advantages over other corrosion control methods. The first major advantage is that polyethylene does not contact soil, which helps prevent corrosion. Another major advantage of using polyethylene is that it is available in a variety of sizes and colors. In addition to the standard clear black, you can also choose custom colors and widths to fit your needs.
After identifying which fittings are most vulnerable to corrosion, you should carefully measure the pipe dimensions to determine the best placement. Make sure that the polyethylene completely encases the pipe and provides a watertight barrier. To secure the ends, use polyethylene tape or moldable sealant. If the surface of the pipe is irregular, use wax tape or a moldable sealant to make the area smooth. Once the polyethylene sheet is in place, you can install concrete anchors and support blocks.
In addition to polyethylene tube and sheet encasement, you should also consider DUCTILE IRON PIPES. They are both durable and inexpensive. In addition, you can select a polyethylene encasement that is designed to extend the life of a pipe by many years and reduce the overall cost of ownership.
Polyethylene encasement offers a variety of benefits over other corrosion control methods. It keeps ductile iron pipes away from the soil, minimizing the risk of corrosion. However, unlike cathodic protection systems, polyethylene encasement is not air or water-tight. It can be used in a variety of applications and is available in several widths and colors.
Black Polyethylene pipe is available in long rolls, and is typically used for the water main between a meter and the house, or for sprinkler systems. Over time, however, black poly pipe can develop leaks. These leaks can be caused by tree roots that press against the pipe. Additionally, rocks in the soil can place pressure on the pipe.
In addition to their low cost, polyethylene encasement can extend the life of the pipes. Often, these pipes are in highly corrosive environments, and encasement can extend their service life. By encasing pipes with polyethylene, corrosion can be minimized and a significant reduction in maintenance costs can result.
For example, the revision to the design factor of PE pipe from 0.32 to 0.40 led to a $32 million savings. This change is beneficial for the industry because it allows the pipe to operate at higher pressures. Another change that leads to unquantified cost savings is the expanded use of PA-11 and PA-12. The new regulations also include unquantified costs associated with incorporating best practices for the industry.
Among other benefits, polyethylene pipe encasement is a good choice for pipelines because it offers effective corrosion protection. The advantages of polyethylene encasement include low production costs and protection for cast iron pipes, which are commonly found in corrosive environments. Its widespread use led to the adoption of the first national standard, ANSI/AWWA C105/21.5, in 1972.
The environmental impact of a pipe in service depends primarily on the amount of leakage that occurs. For polyethylene pipe, it is less than that of an equivalent steel or iron pipe, but it is still important to consider the type of fluid and its potential for damage. In addition to leakage, environmental impact should also be taken into account the corrosion and other effects on nearby structures.

The report also features robust data for asset management plans and life cycle cost assessments. Its 100-year LCA methodology will help utilities minimize risks to water quality and reduce operating costs. The report draws from over 200 sources, including studies and reports. The data is updated every year, and is an essential tool for any utility.
One of the most important steps to minimize environmental impact of plastics is recycling. Recycling plastics reduces oil usage, carbon dioxide emissions, and the quantity of waste that must be disposed of.
