Understanding Schedule 40 and SDR 35

Before we delve into the methods of connecting these two types of pipes, let’s quickly understand what Schedule 40 and SDR 35 actually mean. These terms refer to specific standards set for different types of pipes, especially used in plumbing and drainage systems.

Schedule 40 pipes, also known as “standard” or “pressure-rated” pipes, are made from durable materials like PVC or steel. They are commonly used for water lines, irrigation systems, and other applications where strength and durability are crucial.

SDR 35, on the other hand, stands for “Standard Dimension Ratio 35.” It is a specific type of PVC pipe commonly used for underground or buried applications, such as sewer lines and drainage systems. SDR 35 pipes have a different outside diameter compared to Schedule 40 pipes, which requires special techniques for joining them together.

Frequently Asked Questions (FAQs)

1. Can I connect Schedule 40 PVC to SDR 35 PVC without adapters?

Yes, it is possible to connect Schedule 40 PVC to SDR 35 PVC without adapters by employing a technique called “heating and jamming.” This method involves heating the Schedule 40 pipe end and inserting it into the SDR 35 pipe, creating a snug fit. However, this technique is not recommended for all situations and may not comply with building codes in certain areas.

2. What is the difference between Schedule 40 and SDR 35 pipes?

The main difference between Schedule 40 and SDR 35 pipes lies in their outside diameters and intended applications. Schedule 40 pipes have a smaller outside diameter and are used for water lines, irrigation systems, and other pressurized applications. SDR 35 pipes have a larger outside diameter and are primarily used for underground drainage and sewer lines.
