1. Small-diameter seamless precision steel pipe: This kind of steel pipe is made by piercing and rolling, which has the advantages of high precision, good internal and external surface quality and stable performance. It is mainly used to manufacture mechanical parts with high precision, high strength and high wear resistance, such as hydraulic cylinders and cylinders. Small-diameter thick-walled seamless steel pipe: this kind of steel pipe is made of hot extrusion perforation, which has the advantages of thick wall, high strength and strong compression resistance. It is mainly used for manufacturing high-pressure corrosion-resistant occasions such as oil drill pipes and oil pipes for oil fields.
?
High-precision cold-drawn pipe: this kind of steel pipe is made by cold-drawn process, which has the advantages of high precision, stable dimensional accuracy and good surface quality. It is mainly used for manufacturing precision mechanical parts in automobile, aerospace and oil and gas fields.
Honing precision pipe: this kind of steel pipe is made by honing process, which has the advantages of low roughness of internal and external surfaces, high dimensional accuracy and stable performance. It is mainly used to manufacture mechanical parts with high precision, high strength and high wear resistance, such as hydraulic cylinders and cylinders.
2. Application field? Small diameter seamless precision steel pipe: mainly used in the manufacturing field of high precision, high strength and high wear resistance mechanical parts such as hydraulic cylinder, cylinder barrel and piston rod.
Small-diameter thick-walled seamless steel pipe: mainly used in high-pressure corrosion-resistant occasions such as oil drill pipes and oil pipes for oil fields.
High-precision cold-drawn pipe: it is mainly used to manufacture precision mechanical parts in automobile, aerospace, oil and gas fields.
Honing precision pipe: it is mainly used in the manufacturing field of mechanical parts with high precision, high strength and high wear resistance, such as hydraulic cylinder body and cylinder barrel, and can also be used to manufacture high-pressure pipelines and equipment.
3. Use environment? Small-caliber seamless precision steel pipe: the use environment is generally indoors, and it is less affected by the external environment, such as temperature and humidity.
Small-diameter thick-walled seamless steel pipe: the use environment is generally outdoor or harsh environment, such as high temperature, low temperature and corrosive medium.
High-precision cold-drawn pipe: the use environment is generally indoors, which is less affected by the external environment, but it needs to be kept clean and dry to avoid corrosion damage.
Honing precision pipe: the use environment is generally indoors, which is less affected by the external environment, but it needs to be kept clean and dry to avoid corrosion damage. At the same time, we should pay attention to the control of temperature and pressure to ensure the stability and reliability of its performance. Small-caliber seamless precision steel pipe, small-caliber thick-walled seamless steel pipe, high-precision cold-drawn pipe and honing precision pipe are different in manufacturing process, application field and use environment. Choosing the appropriate steel pipe type according to the specific needs and occasions can improve the quality and performance of products and ensure the safe and reliable use effect.
