Product Description

Ductile iron pipe fittings are high-strength and high-toughness pipe fittings that are widely used in the fields of construction, water conservancy, petroleum, and chemical industry. It is made of ductile iron as raw material, and is made through multiple processes such as melting, spheroidizing, and quenching. It has the characteristics of excellent mechanical properties, wear resistance, corrosion resistance, high temperature resistance, and good sealing.

Ductile iron pipe fittings are a type of pipe fittings that are widely used in the market. The processing process of ductile iron pipe fittings requires attention to quality control and technical requirements at all stages. The following is the basic process of ductile iron pipe fittings processing:
1. Material preparation: The first step in the processing of ductile iron pipe fittings is to select and prepare the raw materials. High-quality ductile iron materials must be selected for cutting, trimming and assembly. At this stage, the physical and chemical properties of the materials must be accurately measured and judged to ensure that the final pipe fittings have good performance.


2.Mold making: Specific molds are required to manufacture ductile iron pipe fittings. The two most important aspects of mold making are: precision and density. The mold needs to be highly precise to ensure that the final pipe fittings meet specifications and meet quality requirements. The density of the mold is equally important. High-density molds can better protect the workpiece and prevent future fatigue and damage.


3.Paint spraying: Spraying paint is an essential step in the processing of ductile iron pipe fittings. In order for the final product to have a good appearance and years of durability, the paint needs to be sprayed on the surface of the workpiece efficiently.
4. Baking and casting: After the paint is sprayed, the workpiece is placed in a baking room for baking. This is to make the sprayed paint dry quickly, eliminate any residual paint and improve its wear resistance. Next, a furnace or similar equipment is used to heat the material to the correct casting temperature. After reaching the appropriate temperature, the molten ductile iron material is injected into the mold.

5. Trimming and polishing: After casting, the ductile iron pipe fittings need to be trimmed and polished. This step requires the fitter to perform delicate operations to remove small flaws that may have occurred during the casting process and polish the surface.
6. Inspection: The last step is to inspect the ductile iron pipe fittings. The purpose of the inspection is to ensure that all products meet the design specifications and quality standards. At the same time, it is also necessary to confirm that the surface of the pipe fittings does not show any cracks, grooves or other defects.
In short, the processing process of ductile iron pipe fittings needs to ensure quality at all links to produce high-quality products and provide better services to customers.
