Packing & Delivery

Stainless Steel Heat Exchanger Tube are surface wash and clean to remove all impurities and stock in the warehouse. Then it is wrapped in thin plastic and also it ends are protected by plastic caps to avoid any damage in transit. Heat Exhanger Shell & tubes is bundled in bubble wrap followed by assorting them in colored plastic bundles. An outer rope is tied to protect the tubing and they are packed in wooden box or container.
