HDPE pipe sizes and dimensions

High-density polyethylene (HDPE) pipes are widely used in water supply, drainage, natural gas transmission, industrial pipelines and other fields due to their excellent corrosion resistance, high strength and long life. As a leading company in the HDPE pipe industry, Puhui Industry provides HDPE pipes in a variety of sizes and specifications to meet the needs of different application scenarios. This article will introduce the size range, specification standards and applications of Puhui Industry HDPE pipes in detail.

 

Size range of HDPE pipes

Puhui Industry"s HDPE pipes cover a variety of sizes from small to large diameters, which can meet a wide range of needs from household water supply to industrial water delivery. The following are common size ranges:

1. Small diameter pipes

Outer diameter range: 20 mm - 63 mm

Application scenarios: household water supply, agricultural irrigation, small drainage systems.

2. Medium diameter pipes

Outer diameter range: 75 mm - 315 mm

Application scenarios: urban water supply, municipal drainage, industrial water.

3. Large diameter pipes

Outer diameter range: 355 mm - 1200 mm

Application scenarios: large water supply projects, sewage treatment, natural gas transmission.

4. Extra large diameter pipes

Outer diameter range: 1200 mm or more (customizable according to customer needs)

Application scenarios: large infrastructure projects, marine engineering, mining drainage.

 

Specifications of HDPE pipes

1. Pressure rating (PN)

The pressure rating of HDPE pipes indicates the maximum working pressure they can withstand. Common pressure ratings include:

PN6: Applicable to low-pressure water supply systems.

PN8: Applicable to medium-pressure water supply systems.

PN10: Applicable to high-pressure water supply systems.

PN12.5 and above: Applicable to ultra-high-pressure water supply or natural gas transmission systems.

2. Standard dimension ratio (SDR)

SDR is the ratio of the outer diameter of the pipe to the wall thickness, which is used to indicate the strength and pressure resistance of the pipe. Common SDR values ??include:

SDR11: High strength, suitable for high-pressure applications.

SDR17: Medium strength, suitable for medium-pressure applications.

SDR26: Low strength, suitable for low-pressure applications.

3. Material grade

Puhui Industry"s HDPE pipes are made of high-quality polyethylene materials, and common material grades include:

PE80: Has high strength and pressure resistance, suitable for general water supply systems.

PE100: has higher strength and pressure resistance, suitable for high-pressure water supply, natural gas transmission and industrial pipelines.

4. Color identification

For easy identification and application, Puhui Industry"s HDPE pipes are color-coded:

Blue: for drinking water systems.

Yellow: for natural gas transmission systems.

Black: for drainage and industrial piping systems.
