Packing & Delivery

ASTM A179 SA179 Seamless Cold Drawn Low Carbon Steel Heat Exchanger Tubes and Condenser Tubes 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
