Seamless Galvanized Water Pipe Steel Pipe Gr.B
Description
ASTM A106B Galvanized Seamless Pipe means that dip A106B pipes into hot liquid zinc to form a coating at both the outside and the inside of the pipe. The process is called hot dip galvanization. The zinc coating prevent pipes away form corrosion and rust

Difference between Hot-Dip Galvanizing and Pre-Galvanizing
| Feature | Hot Dip Galvanization | Pre-Galvanizing |
| Coating Thickness | Thick coating with minimum average requirements of 45-85μm within BS EN ISO 1461 | The coating thickness may vary, but it is typically circa 20μm for sheets and 20-30渭m for tubes |
| Coating Continually | Continuous coating over the whole object | The uncoated area at cut edges |
| Coating Bond | Strong metallurgical bond with the base steel | Strong metallurgical bond with the base steel |
| Coating Formability | Forming after hot dipped galvanizing is not advised as it may damage the coating | A thin coating may be normally formed without any damage |
| Coating Appearance | Normally bright, but can be variable | Normally bright |
| Abrasion Resistance | A thicker layer of hard zinc-iron alloy gives a high resistance to abrasion | Thin alloy layer with reduced resistance to abrasion |
| Sacrificial Protection | Offer the highest level of sacrificial protection | Reduced sacrificial protection due to thin layer coating and at some uncoated areas (cut edges) |
