Custom Machining of Oil Pipeline Stator Tubes

Custom machining of stator tubes for oil pipeline fittings typically requires design and manufacturing based on specific application scenarios (such as the oil, natural gas, and chemical industries) and technical requirements. Here is some key information and advice regarding custom machining of stator tubes:

1. Definition and Use of Stator Tubes

Stator tubes are usually critical components in oil pipeline systems for specific equipment (such as screw pumps or motors), used to fix or guide rotating parts, ensuring the stability and efficiency of fluid transmission. Their material, size, precision, and corrosion resistance need to be customized according to the usage environment.

2. Key Elements of Custom Machining

• Material Selection: Based on the medium in the pipeline system (such as crude oil, natural gas, chemical substances), common materials include:
  • Carbon Steel: Suitable for general environments, with lower cost.
  • Stainless Steel (Austenitic, Duplex Stainless Steel): Corrosion-resistant, suitable for harsh environments.
  • Nickel-based Alloys, Titanium: Used in high-temperature, high-pressure, or strongly corrosive environments.
• Machining Processes:
  • CNC Machining: Ensures high precision, suitable for machining stator tubes with complex shapes, such as CNC lathes and milling machines.
  • Welding Processes: Such as automatic tube-to-tube welding or tube-to-tubesheet welding, ensuring joint strength and sealing performance.
  • Surface Treatment: Such as plating or heat treatment, improving wear resistance and corrosion resistance.
• Execution Standards: Custom machining must comply with industry standards such as HG, GB, ASME, ANSI, DIN, etc., to ensure product compatibility and safety.
• Dimensions and Tolerances: Precisely control parameters such as pipe diameter, wall thickness, and length according to customer-provided drawings or specific requirements.
