Pipe - align Chains
Pipe-align chains needed to center for the purpose of welding two pipe ends against each other.
Smaller bumps and ovality can be compensate by using the centering nuts which are placed where the chain crosses are.
So no tacking work by second or third person are necessary.
For the individual handling, different models are available in galvanized steel / stainless steel (= C / E).
Centering DN 150 (6 "inches) - DN 2000 (80" inches)
Standard Chain
Has a sufficient average *weld machining gap and is optimally suited for normal tube processing.
| Type | recommended from |
*weld machining gap |
| 150(C/E) | Ø 150 mm | 110 mm |
| 200(C/E) | Ø 200 mm | 160 mm |
| 300(C/E) | Ø 300 mm | 240 mm |

Standard Chain Double
Has a sufficient average *weld machining gap and is optimally suited for normal tube processing thick walled pipes and / or larger tube outside diameters.
The double chain crosses it possible to exert more force to the pipe ends!
| Type | recommended from |

| D200(C/E) | Ø 200 mm | 160 mm x 50 mm |
| D300(C/E) | Ø 300 mm | 240 mm x 70 mm |

Short Link Chain
Has the increased number of chain links a lower *weld machining gap.
This ensures optimal pressure distribution and a better centering.

Short Link Chain Double
Has the increased number of chain links a lower *weld machining gap.
This ensures a higher pressure distribution and a better centering.
The double chain crosses allow especially for thick-walled pipes exert more force on the pipe ends!
| Type | recommended from |
*weld machining gap |
| D200(C/E)K | Ø 200 mm | 80 mm x 45 mm |
| D300(C/E)K | Ø 300 mm | 110 mm x 70 mm |
|
|
Long Link Chain
Has by the low number of chain links a larger *weld machining gap.
To the due balance by the lower number of chain links lower pressure distribution, additional plunging bridges be used with chain bolts.
| Type | recommended from |
*weld machining gap |
| D200(C/E)L | Ø 200 mm | 270 mm x 45 mm |
| D300(C/E)L | Ø 300 mm | 365 mm x 70 mm |

* Weld machining gap = the usable range for welding between two chains crosses!
All the chains can be individually adapted (increase or decrease).
Please let us know with a request to the tube inner and outer diameter.
