Product Description

Product Description

The manufacturing process of stainless steel seamless pipes mainly includes the following steps:
1. Raw material selection: Choose high-quality stainless steel raw materials, usually round tubes.
Or square tube blank.
2. Heating the tube blank: Put the tube blank into the heating furnace for high-temperature heating until it reaches
to a certain plastic state to facilitate subsequent processing.
3. Perforation: Put the heated tube blank into the perforation machine and pass it through the perforation roller.
Rotate and squeeze to form a hole in the middle of the tube blank.
4. Finish rolling: The perforated tube blank is rolled multiple times to gradually increase the thickness of the tube wall.
Reduce to meet the size requirements of the finished pipe.
5. Cooling: Water-cool or air-cool the rolled pipe to cool it down quickly.
To eliminate internal stress and improve the mechanical properties of the pipe.
6. Straightening: Straighten the cooled pipe to eliminate bending and twisting.
Curved and other shape defects.
7. Cutting: Cut the straightened pipe to the specified length as needed.
8. Surface treatment: Polishing, pickling and other treatments are performed on the surface of the pipe to improve
Surface Quality.
9. Inspection: Inspect the inner and outer diameter, wall thickness, length and other dimensions of the finished pipe.
As well as surface quality, mechanical properties and other inspections to ensure that product quality meets standard requirements
beg.
10. Packaging: Pack the tubes that pass the test to facilitate transportation and storage.

Application scope of stainless steel seamless pipe

Stainless steel seamless pipe is a pipe with excellent corrosion resistance and is made of stainless steel. It has a wide range of uses in many fields, including the following:
1. Oil and natural gas industry: Stainless steel seamless pipes play an important role in the exploration, extraction, transportation and storage of oil and natural gas. They are used to make equipment such as drilling pipes, well casings, oil pipelines, gas transmission pipelines and storage tanks.
2. Chemical industry: Since stainless steel seamless pipes have good corrosion resistance and high temperature resistance, they are widely used in chemical processes. They can be used to manufacture chemical reactors, heat transfer equipment, petrochemical plants, piping systems, etc.
3. Food and pharmaceutical industry: Stainless steel seamless pipes comply with hygienic standards and are therefore widely used in the food processing and pharmaceutical industries. They are commonly used in the manufacture of food processing equipment, brewing equipment, pharmaceutical delivery pipes, and more.
4. Construction and decoration industry: Stainless steel seamless pipes are widely used in construction and interior decoration. They can be used to make handrails, stairs, railings, doors, windows, furniture, etc.
5. Automotive and aerospace industry: Stainless steel seamless pipes are also commonly used in the automotive and aerospace fields. They can be used to make engine exhaust systems, fuel delivery pipes, hydraulic pipes, etc.
In addition, stainless steel seamless pipes are also widely used in energy, environmental protection, electric power, marine engineering, metallurgy, nuclear industry and other fields.
area. Due to its corrosion resistance, high temperature resistance, and high strength, stainless steel seamless pipe is a reliable and long-lasting pipe choice.
