? As follows:? I. Manufacture of Precision Steel Pipe Precision steel pipe is a kind of steel pipe with high precision and high flatness, and its manufacturing process includes the following steps:
1. smelting: smelting with electric furnace or converter, adding alloying elements to improve the strength and toughness of steel.
2. Continuous casting: pouring molten steel into a continuous casting machine to form a billet with a certain shape.
3. Hot rolling: the billet is heated and hot rolled to form a preliminary steel tube shape.
4. Cold rolling: cold rolling the hot-rolled steel pipe to further accurately control the pipe diameter and wall thickness.
5. Straightening: Straighten the steel pipe with a straightener to ensure the straightness of the pipe.
6. Flaw detection: NDT equipment is used for internal flaw detection of steel pipes to ensure that there are no defects.
7. Surface treatment: carry out surface treatment such as zinc plating and plastic spraying to improve corrosion resistance and aesthetics.
Second, the material characteristics of precision steel pipe? Precision steel pipes are generally made of high-quality carbon structural steel or alloy structural steel. These materials have the following characteristics:
1. high strength: high-quality carbon structural steel and alloy structural steel have high strength and can withstand greater pressure and bending force.
2. Good toughness: This kind of material has good toughness, can withstand impact and vibration, and is not easy to break.
3. Good machinability: These materials have good machinability and can be used for cutting, drilling, bending and other processing operations.
4. Good corrosion resistance: After proper surface treatment, these materials can have good corrosion resistance.
Three. Precision seamless tube made in precision seamless tube is a steel pipe without welded joints, and its manufacturing process includes the following steps:
1. smelting: smelting with electric furnace or converter to ensure the purity of molten steel.
