PVC non-pressure seal pipes are a type of PVC pipe used in applications where the transported fluid is not under pressure or where pressure sealing is not required. Here’s an overview:

1. Material: PVC (polyvinyl chloride) is the primary material used in the manufacturing of these pipes. PVC is chosen for its durability, chemical resistance, and affordability. These properties make PVC pipes suitable for a wide range of applications, including drainage, sewerage, and ventilation systems.

2. Non-Pressure Applications: PVC non-pressure seal pipes are used in applications where the transported fluid is gravity-fed or where pressure sealing is not necessary. These pipes are commonly used for drainage systems, including stormwater drainage, agricultural drainage, and wastewater disposal.

3. Joint Types: PVC non-pressure seal pipes typically use solvent cement joints or compression fittings for joining. These joints provide a secure connection between pipe sections without the need for pressure sealing. Solvent cement joints are formed by applying solvent cement to the pipe ends and then joining them together, while compression fittings use mechanical compression to create a tight seal.

4. Applications: PVC non-pressure seal pipes are commonly used in drainage systems for residential, commercial, and industrial buildings. They are also used in agricultural applications for field drainage and irrigation systems. Additionally, these pipes may be used for ventilation ducts and conduits where pressure sealing is not required.

5. Sizes: PVC non-pressure seal pipes come in a range of sizes to accommodate different flow rates and system requirements. Common sizes include diameters from small bore pipes used in household drainage to larger pipes used in industrial and agricultural applications.

6. Corrosion Resistance: Like other PVC pipes, PVC non-pressure seal pipes are resistant to corrosion, rust, and chemical degradation, making them suitable for use in corrosive environments such as underground installations or in contact with wastewater and soil.

7. Installation: Installation of PVC non-pressure seal pipes is typically straightforward and can be done using simple hand tools. Solvent cement joints require the application of solvent cement to the pipe ends and proper alignment during assembly. Compression fittings are installed by sliding the fitting onto the pipe end and tightening the compression nut to create a secure seal.

Overall, PVC non-pressure seal pipes offer a cost-effective and durable solution for drainage and non-pressurized fluid transport applications, providing reliable performance and ease of installation.
