Introduction of UPVC SCH 40/SCH 80 pipes

UPVC SCH 40/SCH 80 pipes are two common standards of UPVC pipe.SCH 80 pipe is thicker than SCH 40, which allows SCH 80 pipe to withstand higher pressures.The pipe is typically used in higher pressure applications, while SCH 40 is more suitable for general low pressure applications.UPVC SCH 40 pipe is commonly used for non-pressure or low-pressure systems such as sewerage and rainwater collection systems in residential and commercial buildings; UPVC SCH 80 pipe is more commonly used for industrial fluid transfer, chemical plants, pharmaceutical factories, and other locations where high pressure or corrosive media need to be handled.

FAQ of UPVC SCH 40/SCH 80 pipes

Q1,What are UPVC Pipes, their types and advantages?

UPVC refers to unplasticized polyvinyl chloride, which is a kind of piping made from PVC plastic. It is becoming an increasingly preferred choice for water and wastewater systems due to its advantages such as being non-toxic, durable, easy to install and requiring low maintenance compared to traditional materials like metal and concrete.

Q2,How many types of UPVC pipes are there?

There are three types of UPVC pipes: solid wall, cellular core, and multi-layer.

Solid Wall UPVC Pipes

Solid wall UPVC pipes are the most common type among UPVC pipes. They are fabricated from a single piece of material and feature a smooth inner surface. Solid wall UPVC pipes can be utilized for various purposes, such as drainage, sewerage, water supply, and electrical conduit.

Cellular Core UPVC Pipes

Cellular core UPVC pipes have an inner layer of foam, which makes them lighter compared to solid wall UPVC pipes. Cellular core UPVC pipes have diverse applications, including insulation, soundproofing, and impact absorption.

Multi-Layer UPVC Pipes

Multi-layer UPVC pipes are composed of multiple layers of material bonded together. They are available in a wide range of sizes and can be employed for various applications, such as drainage, sewerage, water supply, and electrical conduit. Multi-layer UPVC pipes are more resistant to chemical damage and temperature fluctuations than either solid wall or cellular core UPVC pipes.

Q3,What is the difference between PVC & UPVC?

The main points are that PVC is less strong and durable but more flexible than UPVC, and UPVC is unplasticized, stronger and better for piping projects due to its strength, durability and ease of installation. UPVC Pipes and Fittings: Installation & Maintenance

Q4,What’s the main applications of upvc pipes?

Water Supply Systems: UPVC pipe fittings are widely employed in water supply systems of both residential and commercial structures. They are utilized to link and guide the water flow within plumbing networks, including providing water to faucets, showers, toilets, and other fixtures.
