What does HDPE stand for in Con Edison plastic piping?

• A. Heavy Duty Polyethylene
• B. High Density Polyethylene
• C. High Durability Polyethylene
• D. Hydrogenated Density Polyethylene

Answer: (B)

High Density Polyethylene is what HDPE stands for. This material is favored for gas piping because its higher density gives strength and rigidity while still allowing the pipe to be manufactured in long lengths and joined reliably by heat fusion, creating durable, leak‑tight joints underground. HDPE also offers excellent chemical resistance and low permeability, which are essential for safe gas distribution. The other terms aren’t standard names used for this piping material, so they don’t describe the same polymer used in Con Edison gas mains and service lines.
