Stainless steel fluid pipes are used to convey fluid substances and are used in food, pressure vessels, industrial transportation, and other industries. Pipelines for transporting fluids have very high requirements on technology, the most critical points are:
1. Requirements for pipe material: Since the conveying of objects will cause a certain impact on the pipe wall, there are certain requirements for compressive performance; the compressive strength of 304 stainless steel pipe is as high as 515Mpa, and it has good compressive resistance.
2. Surface finish: The inner and outer surfaces of the stainless steel pipe are polished to make the surface of the pipe fittings bright; that is, we often say mirror surface. The main purpose is to prevent the fluid material in the tube from forming a wall in the tube, which will easily pollute and cause blockage in the tube after a long time. Gangzheng has mastered the core technology of the polishing process, and the surface roughness of the pipe fittings can reach 0.008μm.
3. Passivation layer: After the polishing is completed, the steel pipe needs to be soaked in a passivation pool, and the surface of the steel pipe is oxidized with an acidic passivation solution to form a passivation layer so that the stainless steel pipe can achieve the anti-corrosion effect. Gangzheng has a professional chemical reagent blender to monitor each process in real-time to ensure that the pipe fittings can be pickled and passivated thoroughly without damaging the workpiece.
4. Oil-free degree: After the passivation is completed, carry out oil-free cleaning to remove the oil stains on the surface of the steel pipe. After completion, it needs to be checked with a grease analyzer. The main purpose is to prevent the oil on the pipe wall itself from contaminating the fluid in the pipe.
