Frequently Asked Questions

Q: What is the primary function of a Dismantling Joint in valve manufacturing?

The primary function is to allow for easy installation and removal of valves or other piping components without the need to cut the pipe, providing essential axial adjustment during fitting.

Q: How do I choose between PN10, PN16, and PN25 ratings?

The choice depends on the maximum operating pressure of your system. PN refers to the nominal pressure in bars; for example, PN16 is rated for 16 bars. Always select a rating that exceeds your system's peak pressure for safety.

Q: Can these joints be used with ANSI 150LB standards?

Yes, we provide dismantling joints specifically manufactured to ANSI 150LB standards to ensure compatibility with American piping systems and equipment.

Q: What materials are used to prevent corrosion in the joints?

Depending on the application, we use high-grade carbon steel with protective coatings, ductile iron, or stainless steel alloys to ensure longevity in corrosive environments.

Q: What is the maximum size available for these joints?

Our production range extends up to DN2200 (approximately 88 inches), making them suitable for the largest industrial water and waste treatment pipelines.

Q: Do dismantling joints help in reducing pipe stress?

Yes, by providing a degree of flexibility and allowing for precise alignment, they reduce the mechanical stress and tension on the rest of the piping network.
