In salt chemical production, pipelines serve as the critical “blood vessels” for conveying brine, salt solutions, and acidic/alkaline media. However, the high concentrations of chloride ions, salt crystallization, and acidic/alkaline substances in these environments impose extremely severe corrosion challenges on piping systems.

The piping system of a chemical plant is often vividly described as its “blood vessels.” The health of the blood determines the lifespan and vitality of the entire organism; likewise, proper pipe selection directly decides the operational efficiency, safety margin, and total life‑cycle cost of a chemical facility.

On oilfield job sites, a striking contrast often unfolds: on one side, rubber hoses laid less than two years ago are already covered with a web of fine cracks, hardened and losing elasticity under the relentless sun; on the other, reinforced nylon pipelines that have served for over two decades, having weathered countless cycles of sun and rain, still appear glossy and perform steadily.

In the chemical, metallurgical, mining, and pharmaceutical industries, corrosion protection for piping has always been a core factor determining production safety and operational costs. The continuous attack of strong acids, strong alkalis, high‑salt solutions, and high‑temperature media on the inner walls of pipes forces engineers to tread carefully when selecting materials.

On the front lines of chemical, pharmaceutical, and food processing plants, selecting piping materials is never a mere “nice‑to‑have” upgrade. It is a critical decision that affects production safety, operating costs, and team morale.

In industrial fluid conveying systems—such as those in chemical, power, and metallurgical sectors—pipeline selection directly impacts production safety and continuity. Negative pressure, a seemingly minor operating condition, often proves to be the “Achilles’ heel” of traditional rubber-lined pipes.

In industrial fluid transport, municipal pipelines, pneumatic systems, and many other fields, the reliability of pipe connections directly affects the safety and service life of the entire system. Polyethylene (PE) pipes, thanks to their corrosion resistance, good flexibility, and relatively low cost, have been widely used in many scenarios for a long time.

In buried pipeline projects such as municipal drainage, industrial piping networks, and agricultural irrigation, HDPE (high-density polyethylene) pipes have long occupied a significant market position thanks to their corrosion resistance, light weight, and ease of installation.

Outdoor piping systems are constantly exposed to sunlight, wind, rain, and temperature fluctuations. The issue of material aging is therefore a core consideration that cannot be overlooked during engineering material selection.

In the transport of strong alkaline media such as soda ash and chlor‑alkali, material selection for piping systems has always been a critical challenge for process engineers. Corrosion, stress cracking, high‑temperature degradation – each failure mode can lead to production downtime or even safety incidents.
