Ductile Iron Grooved Fitting History

1. Early Development: The discovery of ductile iron can be traced back to the 1930s. Initially, ductile iron was mainly used for manufacturing mechanical parts and engineering structures. However, because of its high strength and corrosion resistance, attempts were made to use it in piping systems. In the 1960s, ductile iron began to be used in trench systems. Ductile iron trench fittings are gradually recognized and accepted by the market because of their better compressive strength and corrosion resistance compared to traditional cast iron fittings.

2. Standardization and Code Development: As the use of ductile iron groove fittings continues to expand, a number of standards and codes have been developed to ensure their quality and performance. For example, UL (Underwriters Laboratories) and FM (Factory Mutual) in the United States have developed safety certification standards for ductile iron groove fittings. JIANZHI grooved fittings are certified by UL and FM.

3. Material and production technology improvements: The quality and performance of ductile iron has been further enhanced with advances in materials science and production technology. New alloy formulations and heat treatment processes have made ductile iron more robust and durable. In addition, modern production processes and machining techniques have made the production of ductile iron grooved fittings more precise and efficient.

4. Widely used: Ductile iron trench fittings are widely used in construction, industry and municipalities. They are used in various applications such as cooling water systems, fire protection systems, chemical piping, etc. The advantages of ductile iron trench fittings include high reliability, low maintenance cost and long service life, making them the first choice for many engineering projects. JIANZHI grooved fittings are mainly used in fire protection systems.
