Pipe Coupling Clamps – Frequently Asked Questions
1. What is the difference between the Standard and Extended pipe coupling clamps? How do I choose the correct one?
The distance between the two pipe ends (labelled S in the diagram) must not exceed the B length listed in the specifications table.
If the pipes cannot be moved and the gap is too wide, please use an Extended connect pipe coupling clamp to prevent leakage.
2. What is the maximum allowable difference in pipe diameters?
A difference of up to 2–3 mm in outer diameter between the two pipes is acceptable.
3. Can the clamp be used if the pipe is close to a wall or another pipe? What is the thickness of the clamp?
Clamp thickness is calculated as: (T – Outer Diameter of Pipe) / 2.
For example, for a standard DN100 pipe: (142mm – 114.3mm) / 2 = 13.9mm.
4. Can different pipe materials be connected?
Yes, all types of pipe materials can be connected.
5. Are there any pipe types that are not compatible?
Not suitable for glass pipes or flexible hoses.
Also not suitable for sanitary pipes carrying food-grade fluids.
Frequently Asked Questions (FAQ)
What is the lifespan of pipe coupling clamps?
Under normal usage conditions, connect pipe clamps can last for 15 to 20 years.
Will the coupling come loose during vibrations/earthquakes?
The coupling features serrated grips on both ends, allowing it to bite firmly onto the pipe. Even during seismic activity or vibrations, it will not come loose.
Can the pipe clamp be reused?
Yes, it is reusable.
How do I select the correct size?
First, measure the outer diameter of the pipe you wish to use. Then, refer to the connect pipe clamp specification page to select the appropriate size. If you're unsure, feel free to consult our sales representative.
