Header Plugs
PipeServ is committed to delivering top-notch reliability and aftermarket support in air-cooled heat exchanger systems. With decades of experience, we specialise in the design, manufacture of essential components such as header plugs, ensuring optimal performance and durability.
Header plugs are essential for closing the access holes in the plug sheets of header boxes in air-cooled heat exchangers. These access holes are necessary for tube sheet maintenance, whether the tubes are roller-expanded into grooves or welded.
Our header plugs are designed with Unified Fine Threads (UNF), ensuring a secure fit and reliable sealing performance, even under the most demanding conditions.
Gaskets –
A Key Component
The plug gasket is a metal ring shape that fits onto a machined surface between the plug and plug sheet. The plug gaskets are typically 2-3mm thick and made of a compatible material which is much softer than the plug and plug sheet. The table below details compatible materials.
Common Challenges and Solutions
- Galling: Prevent thread damage by avoiding over-torqueing and using the recommended lubricants.
- Leaks: PipeServ supplies gaskets with precise tolerances to minimize the risk of leaks caused by improper seating or surface imperfections.
Best Practices – Do’s and Don’ts
Do’s:
- Always use new gaskets
- Insert plugs by hand and torque using calibrated tools.
- Use nickel- or chrome-based anti-seize lubricants.
Don’ts:
- Never reuse gaskets.
- Avoid using power tools for installation.
- Refrain from over-torqueing or using copper-based lubricants.
