What are the main differences between malleable steel pipe fittings and galvanized pipe fittings?
| Sr.No | Parameter | Malleable steel pipe fittings | Galvanized pipe fittings |
| 1 | Materials | Made of high quality carbon steel or stainless steel | Made of carbon steel or low alloy steel |
| 2 | Coating | No coating is required because the material itself has excellent corrosion resistance. | Through galvanizing process, zinc metal is coated on the surface of steel pipe to improve corrosion resistance. |
| 3 | Corrosion Resistance | Even in high temperature and high pressure environments, malleable steel pipe fittings will not lose their performance; | After a period of time, the zinc layer may fall off or rust. |
| 4 | Range of application | For high temperature and high pressure applications, such as petrochemical, electric power, natural gas and nuclear power industries. | Suitable for construction, hydraulic, chemical and other low pressure applications. |
| 5 | Manufacturing technique | The manufacturing process is complex and costly, requiring multiple processes, such as forging, heat treatment, tempering, grinding, etc. | The manufacturing process is relatively simple and only needs to be treated with galvanized coating. |
In general, malleable steel pipe fittings and galvanized pipe fittings have differences in material, coating, scope of use, manufacturing process, corrosion resistance and so on. Therefore, when choosing accessories, it is necessary to choose according to the specific situation, so as to ensure the quality and use effect.
