Characteristics of PE farmland irrigation pipes in Shandong

Characteristics of PE farmland irrigation pipes in Shandong

■ Good sanitary performance: PE pipes are processed without adding heavy metal salt stabilizer, with harmless materials, no scaling layer, and no bacteria, which solves the secondary pollution of urban drinking water.
■ Superior corrosion resistance: except for a few strong oxidants, it can resist the corrosion of various chemical media; No electrochemical corrosion.
■ Long service life: Under rated temperature and pressure conditions, PE pipes can be safely used for more than 50 years.
■ Good impact resistance: PE pipe has good toughness and high impact strength, and the heavy objects directly press the pipe, which will not cause the pipe to be broken.
■ Reliable connection performance: the strength of PE pipe hot-melt or electrofusion interface is higher than the pipe body, and the joint will not be disconnected due to soil movement or live load.
■ Good construction performance: the pipeline is light, the welding process is simple, the construction is convenient, and the comprehensive cost of the project is low.
Pipe connection:
■ Electric welding: special electric welding machine is used to connect straight pipes with straight pipes and straight pipes with pipe fittings. Generally, it is used for pipes below 160mm.
■ Hot melt butt connection: special butt welding machine pipes are used for connection, generally used for pipes above 160mm.
■ Steel plastic connection: flange, thread thread and other methods can be used for connection.
■ Corresponding tools shall also be prepared to facilitate construction and ensure construction quality.

For example, rotating cutter cuts pipes; Rotating scraper -- scrape off the oxide scale on the surface of the pipe; Wall climbing scraper -- scrape off the scale on the surface of large-diameter pipes; Gas cut-off tool -- to realize gas cut-off field operation.
Connection steps:
1. Clamp and clean the port
2. Adjust and polish the port
3. Port alignment
4. Pressure welding
5. Pressure relief cooling
