Packing & Delivery

Molybdenum Alloy Steel Steel Heat Exchanger Tubes T1 T1a T1b  Packing Details  : In bundles or in wooden boxes packaging

Delivery Details : 30-60days 

 

In hexagonal bundles packaging with woven 

In hexagonal shaps,the tubes will be well fixed,so it can avoid the damages when delievey .
 

In wooden boxes.

Solid packaging ,protecting tubes from damages much better.
 
 
In poywooden packaging,It cut the packaging costs also it can protect tubes well
 
In bundles with end caps.well protect tubes from rust.
 
Carton Packing suit for the cutting length
