1. We should first know which standard flanges you use,because we have to make sure that all flanges match your pipes connections.The most commonly used flanges standards are British Standard and America Standard.
2. Generally water tank should be equipped with four flanges such as inlet,outlet,overflow and drainage flanges.If you need more or extra types of flanges,please kindly tell us in advance.
As over 20 years of water tank manufacturer,we have raised a lot of packing experience.So far,all panels are packed in iron frame which better protect GRP water tank panel corner and flange bar damage because of sea waves and inappropriate loading and unloading.
