Problems solved by technology

[0002] Most of the existing stainless steel pipe fittings are hot-rolled seamless pipes with poor surface quality. The bumps during loading and unloading and transportation will cause scratches on the surface of the pipe, which will damage the surface of the pipe, which will cause damage to the later use of the pipe. influences

Embodiment 1

[0026] The present invention provides such figure 1 A surface treatment method for stainless steel pipe fittings shown specifically includes the following steps:

[0027] Step 1, paraffin wax dyeing: adding solid paraffin raw materials into the sealed reaction kettle, and adding monascus pigment into the inside of the sealed reaction kettle at the same time, the mass percentage of monascus pigment and solid paraffin wax is 0.3%, and then heating for 10 minutes at a heating temperature of 150 degrees Celsius. Stirring is continued during the heating process, so that the monascus pigment and solid paraffin are effectively mixed, and after the heating is completed, it is left to cool to obtain red paraffin;

[0028] Step 2. Rust removal of pipe fittings: use a cloth wheel polishing machine to derust the surface of the stainless steel pipe, and set the processing time to 7 minutes so that the surface roughness of the pipe is less than or equal to 0.5um;

[0029] Step 3. Degreasin...

Embodiment 2

[0039] The present invention provides such figure 1 A surface treatment method for stainless steel pipe fittings shown specifically includes the following steps:

[0040] Step 1, paraffin wax dyeing: add the solid paraffin raw material into the sealed reaction kettle, and add the red yeast rice pigment to the inside of the sealed reactor at the same time, the mass percentage of the red yeast rice pigment and the solid paraffin wax is 0.4%, and then heat for 13 minutes at a heating temperature of 160 degrees Celsius. Stirring is continued during the heating process, so that the monascus pigment and solid paraffin are effectively mixed, and after the heating is completed, it is left to cool to obtain red paraffin;

[0041] Step 2, rust removal of pipe fittings: use a cloth wheel polishing machine to derust the surface of the stainless steel pipe, and set the processing time to 8 minutes, so that the surface roughness of the pipe is less than or equal to 0.5um;

[0042] Step 3. ...

Embodiment 3

[0052] The present invention provides such as figure 1 A surface treatment method for stainless steel pipe fittings shown specifically includes the following steps:

[0053] Step 1, paraffin wax dyeing: add solid paraffin raw materials into the sealed reaction kettle, and add monascus pigment into the inside of the sealed reaction kettle at the same time, the mass percentage of monascus pigment and solid paraffin wax is 0.5%, and then heat for 15 minutes at a heating temperature of 170 degrees Celsius. Stirring is continued during the heating process, so that the monascus pigment and solid paraffin are effectively mixed, and after the heating is completed, it is left to cool to obtain red paraffin;

[0054] Step 2. Rust removal of pipe fittings: Use a cloth wheel polisher to derust the surface of the stainless steel pipe. The processing time is set to 9 minutes, so that the surface roughness of the pipe is less than or equal to 0.5um;

[0055] Step 3. Degreasing the pipe fitt...

Abstract

The invention discloses a surface treatment method of stainless steel pipe fittings. The surface treatment method specifically comprises the following steps that step 1, paraffin dyeing is carried out, specifically, a solid paraffin raw material is added into a sealed reaction kettle, monascus pigment is added into the sealed reaction kettle at the same time, then heating is carried out for 10-15minutes, the heating temperature is 150-170 DEG C, stirring is carried out continuously in the heating process to effectively mix the monascus pigment with the solid paraffin, and cooling in a placingmode is carried out after heating is completed to obtain red paraffin; and step 2, the pipe fittings are derusted, specifically, the surfaces of the stainless steel pipes are derusted by using a cloth wheel polisher with an arranged treatment time of 7-9 minutes, so that the surface roughness of pipes is less than or equal to 0.5 [mu]m. According to the surface treatment method, all scratched parts on the surface of the pipes can be clearly found and repaired in sequence, so that the situation that the performance of the pipes is affected due to partial scratches and residual damaged parts isavoided, and the subsequent normal use of the pipes is ensured.

Description

technical field [0001] The invention relates to the technical field of processing stainless steel pipe fittings, in particular to a surface treatment method for stainless steel pipe fittings. Background technique [0002] Most of the existing stainless steel pipe fittings are hot-rolled seamless pipes with poor surface quality. The bumps during loading and unloading and transportation will cause scratches on the surface of the pipe, which will damage the surface of the pipe, which will cause damage to the later use of the pipe. influences. [0003] Therefore, it is necessary to invent a surface treatment method for stainless steel pipe fittings to solve the above problems. Contents of the invention [0004] The purpose of the present invention is to provide a surface treatment method for stainless steel pipe fittings. By using high-temperature wax penetration to find out all the scratches and damaged parts on the surface of the pipe, and make the paraffin melt and flow ou...
