Even the delivery time is very urgent, Hebei haihao group flange factory finished the production and packing for the high pressure flanges order in time. 

The flanges in this order are used for Oil & Gas project, which has a very strictly quality request . Because of the high pressure situation of the piping system, the EPC contractor of the project placed this flanges order to our Haihao Group , they know and trust our quality control and finish for the high pressure flanges. 



Besides of the high level quality control in production, the shipment package is also important. To protect the flanges from damage in the shipment , our factory used the plastic tapes wraping around them .After that we use the rubber cap cover the whole flanges by the sealing face side , it will prevent the Raise Face from cracking. Or else , there may be some leaking if the Raise Face are broken. 



Finally, every flange we use a seperate wooden pallet to packing it , this also will be helpful to guarantee the quality from the long distance shipment. We trust our flanges would be installed successfully in this important project.  Thanks for the confidence to us from our clients.
