What material is a high pressure line (3000 psi or greater) carrying a hazardous substance usually made of?

High-pressure lines that carry hazardous substances, especially those operating at 3000 psi or greater, are generally constructed from corrosion-resistant steel. This material is preferred due to its ability to withstand high pressure and provide the necessary strength to prevent ruptures or leaks, which could have catastrophic consequences when transporting hazardous materials.

Corrosion-resistant steel is also advantageous in various environments where exposure to chemicals and moisture may lead to degradation, ensuring lasting durability and safety in the transportation of potentially dangerous substances.

While other materials like aluminum alloys and rubber might be used in different applications, they do not offer the same level of safety and reliability required under such high-pressure conditions. Plastic tubing, while lightweight and flexible, lacks the strength and resistance needed to safely transport hazardous substances at extreme pressures.
