3PE Coated Steel Pipe Manufacturer: Explaining How 3PE Coated Steel Pipes Are Produced
2022-05-07
You know 3 PE Anti-corrosion steel pipe The production method? Next, 3 PE Anti-corrosion steel pipe The manufacturer will give you a brief introduction.
1. Visual inspection. Prior to processing, skilled workers shall perform a visual examination of each steel pipe and inspect them individually. If a pipe exhibits severe mechanical damage, scale, cracks, dents, or other defects, it shall be deemed non‑conforming and returned. When inspecting threaded pipe ends, any flattened or distorted openings must be corrected promptly; if correction is not feasible, the pipe shall be scrapped.
2. Rust removal of pipe fittings: The steel pipes to be subjected to corrosion treatment are transported to the upper platform of the processing line and undergo flame heating to remove moisture, oil, and other contaminants from their outer surfaces. The temperature is maintained at… 40 to 60 between degrees Celsius, use PW-380 The steel pipe shot-blasting rust removal machine performs rust removal and, subsequently, further surface treatment to eliminate rust, oil contamination, oxide scale, and other residues, while also grinding any areas that fail to meet quality standards.
3. After polishing, the outer surface of the steel pipe shall be subjected to a secondary treatment using a dust‑removal device to eliminate any residual rust and dust, after which… 4 Apply the epoxy powder coating within one hour.
4. Preheat the steel pipe. Prior to epoxy powder coating, a preheating treatment shall be performed. Select an appropriate temperature based on the pipe diameter and feed rate, but ensure that it does not exceed 275 Degree.
5. Adhesive coating and polyethylene tape wrapping are performed during the gelation of the epoxy powder adhesive. During the transverse winding process, ensure that the polyethylene layer remains intact, and thoroughly roll‑compact both the overlapping sections of the polyethylene and the polyethylene on either side of the weld seam.
6. After the anti-corrosion coating on the steel pipe is completed, it shall be cooled and fixed in place, and a circulating-water quenching chamber shall be used to… Anti-corrosion steel pipe The surface of the anti-corrosion coating is cooled.
7. Make a cut and leave the end exposed; cool the anti-corrosion coating of the steel pipe with cold water, and reserve the required length at the pipe end as specified. 100-120mm The length.
8. Grind the pipe ends and clean them with a wire brush.
That concludes… Zhongyuan Pipeline Manufacturing Co., Ltd. Provided for you Anti-corrosion steel pipe Information!
