HDPE pipes are widely used in various industries and applications due to their excellent properties, such as high strength, durability, flexibility, and chemical resistance. The 90 mm diameter refers to the outer diameter of the pipe.

Features and benefits of a 90 mm HDPE pipe:

1. High Strength: HDPE pipes have a high tensile strength, making them suitable for both underground and above-ground applications. They can withstand high pressure and load-bearing capacities.

2. Durability: HDPE pipes are highly resistant to corrosion, abrasion, and chemicals, ensuring a longer lifespan compared to other pipe materials. They are ideal for applications where long-term performance is required.

3. Flexibility: HDPE pipes have excellent flexibility, allowing for easy installation and handling. They can be bent and curved to accommodate changes in terrain, reducing the need for fittings and joints.

4. Lightweight: HDPE pipes are lightweight compared to traditional pipe materials like metal or concrete. This characteristic makes transportation and installation more manageable, leading to cost and labor savings.

5. Leak-Free Joints: HDPE pipes can be joined using various methods, including butt fusion, and electrofusion. These joints provide a leak-free and reliable connection, minimizing the risk of water or gas leakage.

6. Chemical Resistance: HDPE pipes are resistant to a wide range of chemicals, making them suitable for transporting different types of fluids, including water, sewage, and gases. They are commonly used in industries such as agriculture, mining, dredging, municipal water supply, and wastewater treatment.

7. Longevity: HDPE pipes have a long service life, typically exceeding 50 years under normal operating conditions. This durability reduces the need for frequent replacements and maintenance, resulting in cost savings over the pipe's lifetime.
