Should You Use Customised Seals or Generic?

Ensuring an industrial pipe network doesn't leak is often what people will think of when asked about seals. The seals cover connections between pipes and other parts of the system and prevent whatever is in the pipes from leaking out. While this is a major role for the seals, it isn't the only one.

When choosing a new sealing system for your equipment, the seals need to fit well and stop material from leaking out at weak points in the connection. In addition, they must also be tough and thick enough to prevent breakthroughs and unwanted intrusion. Well-made seals should not deteriorate quickly, as that means they could form openings that could allow in contaminants and put out dangerous gases. Because your facility's needs may vary from department to department, customised seals are the better choice.

Protecting Workers

Pipes that transport high-pressure gases or hold toxic liquids pose a risk to workers around them. Seals must be tough enough to prevent the connection between the pipe and other structures from bursting open. However, the body of the sealing system is vital, too. You don't want the middle of the seal cracking open from pressure and letting high-pressure gas out. Further, you don't want the seal deteriorating due to the corrosive nature of a liquid inside the system. A customised sealing system can be built for the specific materials the system contains and ensure that the seals can withstand the pressure and corrosion risks.

Preventing Intrusion

Seals also prevent intrusion into the system. Thin seals made of cheap material might keep syrup well-contained in equipment in an industrial food processing facility, but pests could chew through those thin seals to get to what's inside. However, if the seals are custom-made for your facility and the equipment's purpose, you could get seals that are resistant to attacks by pests. Likewise, seals on marine equipment subject to rushing water or high salinity could break down over time if not made of the right material. Fortunately, customised sealing systems made for marine/high-salinity environments can prevent this problem, keeping whatever is in the equipment inside the system, and water and salt on the outside. These are just two examples, but these concerns are important to acknowledge any time you have a sealed system carrying materials that you don't want to be affected by outside forces.

Ensuring Purity

Similar to not allowing intrusion, in general, is the concept of protecting the purity of the substance in the sealed system. You don't want water mixing with gas, for example, nor do you want dust getting into a pipe used to carry ingredients through a food processing facility. Even if the items inside the pipe can't leak out (e.g., a food ingredient too big for the hole forming in a bad seal), dust and other contaminants can get in.

Customised sealing systems take the material inside the system and the forces outside the system into account. The result is a sealed system that protects and contains for a long time with minimal issues. For more information about sealing systems, contact an equipment provider.
