Embodiment 1

[0020] A precision, high-gloss, ultra-clean stainless steel pipe degreasing cleaning method, the main equipment necessary for cleaning is an ultrasonic cleaning machine, a drying box, an air compressor, etc. The method for degreasing and cleaning the inner and outer surfaces of the entire stainless steel pipe includes the following steps in turn:

[0021] In the first step, take 4500g xylene, 2500g toluene, 2000g isopropanol and 1000g alkyl alcohol polyoxyethylene ether to make a cleaning mixed solvent A and place it in a long tank, and soak the steel pipe in it for 2 minutes. It is best to lift and lower the two ends of the steel pipe alternately to facilitate cleaning of the inner wall;

[0022] The second step is to take out the steel pipe and place it vertically to dry;

[0023] The third step is to put the steel pipe in the sink for 10-20 minutes, take it out and rinse it with high-pressure water inside and outside;

[0024] The fourth step is to place the steel pipe in...

Embodiment 2

[0028] The difference between the second embodiment and the first embodiment is that the mixed solvent A for cleaning is a mixed solvent of 5500g of xylene, 1500g of toluene, 1500g of isopropanol and 1500g of fatty alcohol polyoxyethylene ether. The solvent used for scrubbing is ethanol. All the other are the same as embodiment one.

Embodiment 3

[0030] The difference between embodiment three and embodiment one is only: cleaning mixed solvent A is 5000g xylene, 2000g toluene, 1500g isopropanol and 750g alkyl alcohol polyoxyethylene ether and 750g fatty alcohol polyoxyethylene ether mixed solvents. The solvent used for scrubbing is ethanol. All the other are the same as embodiment one.

Abstract

The invention relates to a grease removing method for cleaning a precise, highly-polished, super-clean stainless steel tube, which comprises the following steps: a) setting the flux A in the elongated slot, immersing the tube in the flux, b) drying the tube vertically, immersing it in the water bath, c) cleaning up the tube inside and outside with water with high pressure, d) setting the tube in the ultrasonic cleaning tank, injecting pure water to clean ultrasonically, e) heating and drying the tube with vent, scouring the tube inside and outside with the izar soaked the flux B, cleaning the inner hole through the compressed air blowing the cotton ball. The flux A is the mixed solution of 45-55% xylene, 15-25%toluene,10-20%alcohol isopropylicum and 10-15%interfacial active agent. The invention does not damage the surface precision of the tube, and makes the tube has good surface.

Description

Technical field: [0001] The invention relates to a stainless steel seamless pipe, in particular to a method for degreasing and cleaning a precision, high-gloss, ultra-clean stainless steel pipe. This stainless steel tube is more and more widely used in high-tech fields such as electronics, video equipment, instrumentation, precision machinery, and aerospace exploration. Background technique: [0002] Lubricating oils and other pollutants are used in the processing of steel pipes before heat treatment and in further processing after heat treatment. If they are not completely removed and some are brought into the high-temperature heat treatment furnace, they will be with the high temperature at high temperature. The steel pipe produces a chemical reaction that turns the steel pipe yellow and black, thus destroying the surface quality of the steel pipe. And these reactants attached to the steel pipe surface are difficult to remove, so that the whole manufacturing process fails...
