HDPE-High Density Polyethylene
Because of its inherent advantages, plastics may be superior to metals. They are lighter, do not require open-fireconnections, and are flexible enough to simplify installation and reduce fracture caused by freezing. Plastics are usually low-cost and resistant to corrosion and scaling that plague metals in some applications.
HDPE-High Density Polyethylene-is a common industrial plastic that is highly utilized in modern applications. Federal regulation oversees the use and service of HDPE. If the HDPE propile pipe is made of the following materials, a tank made of HDPE is safe for storing drinking water and can safely drink the stored water: FDA-approved food-grade BPA-free, unused polyethylene resin, which is also: ANSI/ NSF 61 Approved for potable water applications.
In the application of drinking water, the plastic produced some controversy. The polybutene pipe material introduced in the 1970s led to unacceptable leakage problems and eventually led to a large-scale collective action. Polyvinyl chloride (PVC) and chlorinated PVC (CPVC) tubes are common. However, some environmental groups say the risksassociated with PVC production and pipeline handling exceed the benefits of these materials.
High density polyethylene (HDPE) is one of the "good" plastics that can be used safely in food and water. A commonplastic memory aid can be found from a variety of sources: "one, four, five and two, all of which are good for you."This rhyme refers to the recycling code on the lastic enntainer, one of which is PET, two are Horc propile pipe vIslow density polycthrlene (loPE), rifth, pulypropylene (PP). PPRC found no evidence of any widespread health problems associated with the use of HDPE in food and beverage or drinking water applications.
