SCH40 UV Resistant Electrical Wiring PVC Pipe

Introduction of SCH40 PVC Pipe

PVC pipe (polyvinyl chloride pipe) is one of the most commonly used pipe materials in modern construction, industrial, and municipal engineering. The two specifications, SCH40 and SCH80, are the most common types of applications. After rigorous testing and certification, they offer significant advantages in pressure resistance, corrosion resistance, and ease of installation. Whether it is industrial, municipal, water treatment, or drainage systems, SCH40 and SCH80 pipes offer superior performance and long life.

Multiple specifications: Available in a wide range of sizes from 1/2 “to 14” (or more significant) to meet different project needs.

Smooth inner wall: The smooth inner wall design reduces fluid resistance and improves flow efficiency while being less prone to scaling, making it easy to clean and maintain.

Corrosion resistance: Excellent chemical resistance, suitable for all kinds of corrosive media.

Simple construction: can use cold glue solution method, construction is fast and easy, and the joint is not easy to leak.

Electrical safety: Some products are UL and CSA certified, in line with the safety standards of electrical applications.

2. SCH80 PVC Pipe

High strength: The pipe wall is thicker, the pressure resistance is stronger, and it can withstand 3-4 times the rated pressure.

High pressure resistance: Suitable for high pressure fluid transmission system, to ensure the stability and safety of the system.

Ultraviolet resistance: Laid outdoors for a long time, life can reach more than 30 years.

Chemical stability: Not easy to cause secondary pollution, suitable for drinking water system.

Versatility: Can be used for a variety of industrial applications, including electroplating, waste acid lye discharge, aquarium, etc.

FAQ of SCH40 PVC Pipe

Q1.what are the main differences between SCH40 and SCH80?

The main difference between the SCH40 and the SCH80 is its wall thickness and its ability to withstand pressure. The SCH80 has thicker tube walls and is therefore able to withstand higher pressures, making it suitable for high-pressure fluid transfer systems. And the SCH40

Q2.why choose PVC pipe instead of pipe made of other materials?

PVC pipe has good corrosion resistance, UV resistance,

Q3: The difference with CPVC pipe?

Upper temperature limit: PVC 60℃ vs CPVC 93℃

Chemical resistance: CPVC has better resistance to aromatic hydrocarbons

Installation method: CPVC requires special adhesive

Q4: How to install in extreme weather?

Low temperature environment: use low temperature adhesive (construction temperature ≥-5℃)

High temperature area: Reserve 8-10mm expansion gap every 6 meters

Strong sunshine area: covered with aluminum foil sunscreen layer (reduce the coefficient of thermal expansion)

Q5: Service life guarantee?

10 years warranty (subject to the following conditions) :

Working pressure ≤ 80% of the rated value
