What Is a Pipe Bending Spring?
A pipe bending spring is a tool designed to bend pipes, especially copper pipes, without crushing or deforming them. It operates on the principle of a spring, allowing the pipe to be bent at various angles. There are two main types: one for standard copper pipes and another for coated copper pipes that can be used without removing the coating or insulation.
Uses of Pipe Bending Springs
Pipe bending springs are typically used for simple bending tasks, such as in air conditioner installation. They are particularly handy when standard benders are impractical or when a tight bend is required. For smaller pipes, such as 1/4″ or 3/8″, hand bending may be feasible. However, for larger sizes like 1/2″ and above, a bender is essential. The use of a pipe bending spring results in a clean, wrinkle-free finish.
For copper pipes, these tools are beneficial for short-distance work, such as connecting outdoor units. Coated copper pipe bending springs can be used post-flaring and are helpful in adjusting the bending angle to match actual requirements.
How to Select Pipe Bending Springs
When choosing a pipe bending spring, consider the size, material, and application:
- Size: Available sizes for copper and coated copper pipe bending springs vary. Copper pipe springs come in sizes like 1/4, 5/16, 3/8, 1/2, 5/8, and 3/4 inches, while coated copper pipe springs are available in 3/8, 1/2, 5/8, and 3/4 inches.
- Material: Made from either stainless steel or steel, stainless steel springs are rust-resistant and often used for coated copper pipe bending due to their strength. Steel springs, sometimes zinc-plated or chrome-plated for smooth removal, are more commonly used for copper pipes and tend to be more affordable.
- Application: Copper pipe bending springs are suitable for bending soft copper and aluminum pipes. Those for coated copper pipes enable bending without removing insulation and allow for tighter radius bends. Vinyl chloride pipe bending springs can bend vinyl pipes without inner diameter distortion by heating the bending area.
