Small-diameter spiral wound 3PE anticorrosive steel pipe is a pipeline anticorrosive material widely used in petroleum, chemical, natural gas and other fields. It is produced by hot melt extrusion process by using high-density polyethylene (HDPE) pipe as the outer layer, polypropylene (PP) pipe as the middle layer, adhesive and polypropylene (PP) tape as the inner layer. This article will introduce in detail the characteristics, production process and use of small-diameter spiral wound 3PE anticorrosive steel pipe. Anti-corrosive steel pipes
1. Features. 1.Strong anti-corrosion performance: small-diameter winding 3PE anti-corrosion steel pipe has good anti-corrosion performance, which can effectively prevent pipeline corrosion and prolong the service life of pipeline.
2.Good chemical corrosion resistance: small-diameter spiral wound 3PE anticorrosive steel pipe can resist the erosion of a variety of chemicals, especially the erosion of acidic substances.

Second, the production process.
Small-diameter spiral wound 3PE anticorrosive steel pipes are produced by hot melt extrusion process. The specific steps are as follows:
1.The high-density polyethylene (HDPE) pipe is used as the outer layer, the polypropylene (PP) pipe is used as the middle layer, and the adhesive and polypropylene (PP) tape are used as the inner layer, and the tube blank is made through a precise extrusion process.
2.The tube blank is placed in a hot melt extruder and heated to a molten state.
3.The molten tube blank passes through a mold and a traction device to form a pipe with the required outer diameter and wall thickness.
4.The pipes are cooled, pulled and cut to make a finished product.
3. Use. Small-diameter spiral 3PE anti-corrosion steel pipes are widely used in pipeline anti-corrosion in petroleum, chemical, natural gas and other fields. For example:
