Nine Production Processes for Rubber Lined Pipelines

For various solid particles, powders and slurries transported by industrial and mining enterprises, due to the harsh working conditions, the actual situation of serious wear and tear is often encountered, and traditional pipelines can hardly meet the requirements of use.

Rubber lined pipelines(lined steel pipe) are a new type of pipeline that is not easily scaled, highly wear resistant, highly impact resistant and self-lubricating.

Rubber lined pipeline is a kind of external steel or hard structure for the pipe skeleton of the pipeline, wear-resistant, anti-corrosion and high temperature resistant rubber as the lining layer, through the rubber itself physical and chemical properties so as to reduce the role of the pipeline transport medium on the external structure such as impact, corrosion, etc., its buffering effect due to rubber, greatly extending the service life of the pipeline.

So how is the wear-resistant rubber-lined pipeline made? Next let’s take a look at its nine production processes!

1、Select seamless steel pipe without pits and smooth surface as the mother material.
2、According to the size set by the customer, welding flange.
3, trim the spatter of the welded flange at the end of the pipe.
4、Put the welded steel pipe into the sand blasting machine to remove rust.
5、Manually brush the primer twice, glue slurry twice, wait for the glue slurry to dry and then send the rubber plate into the inside of the pipe.
6、Compact with pressure roller and trim the edges.
7、Brush the lapped edge with the rubber slurry again.
8、Send the rubber lined steel pipe into the high temperature vulcanisation tank for high temperature vulcanisation.
9, out of the tank after the surface inspection of rubber has no extrusion, scratches, and finally electric spark detection.
