Angel hair, also known as streamers or snakeskins, is a common problem in the plastics industry that occurs during pneumatic conveying of plastic pellets. These thin strands of plastic can clog pipelines, disrupt production, and even degrade the quality of the pellets.
SPIRAflo: A Proven Solution
SPIRAflo is a technology that uses a unique spiral groove pattern to prevent the buildup of angel hair. The grooves are created using a cold-forming process that displaces metal rather than cutting into it. This method creates a series of ridges and valleys that disrupt the airflow, preventing material buildup and the formation of angel hair.
SPIRAflo has several advantages over shot peening and a groove-type process:
It is more effective at preventing angel hair buildup.
It is more durable and less prone to damage.
It is more consistent, ensuring optimal performance throughout the pipe.
It is more affordable than other methods.
It extends pipe life.
There is no additional pressure drop or horsepower requirement.
It is backed by a five-year warranty.
In addition to these advantages, SPIRAflo is also easier to install and maintain than other methods. The spiral groove pattern is self-cleaning, which helps to prevent clogging and reduce maintenance costs.
Alternative Solutions
There are a few different methods used to address angel hair in the plastics industry. Two of the most common include shot peening and a specific groove-type process. While both of these methods have been used in the past, they have some serious limitations when compared to SPIRAflo.
Shot Peening
Shot peening uses a high-velocity stream of small beads to blast the interior surface of the pipe, creating small dimples or indentations. The goal of these indentations is to disrupt the airflow and prevent the buildup of angel hair. However, shot peening has several drawbacks:
It can be time-consuming and expensive, requiring specialized equipment and trained personnel.
The process can weaken the pipe, making it more susceptible to damage and failure.
Shot peening can also create inconsistencies in the pipe surface, which can worsen the angel hair problem in some cases.
Groove-type process
This process cuts grooves in the interior surface of the pipe using a tool. Like shot peening, the goal is to disrupt the airflow and prevent the buildup of angel hair. However, this process also has some drawbacks:
The grooves can be prone to clogging, especially with materials that are sticky or have a high moisture content.
The cutting process can create additional angle hair and streamers due to the sharp edges
The process can be difficult to control, leading to inconsistencies in the groove depth and spacing.
This process can also be more expensive than SPIRAflo.
The SPIRAflo Advantage
SPIRAflo is a superior solution for preventing angel hair buildup in pneumatic conveying systems. It is more effective, durable, consistent, and affordable than other methods. If you are looking for the best way to protect your investment and ensure the efficient operation of your pneumatic conveying system, SPIRAflo is the clear choice.
