Hastelloy C-276 pipe and tubing are the premier choice for fluid transport in the world's most aggressive chemical environments. As a nickel-molybdenum-chromium superalloy, it provides a "failsafe" solution for piping systems where standard stainless steels or even high-performance duplex grades would suffer rapid localized attack or catastrophic failure.

Hastelloy C-22 pipe and tubing represent the next evolution in high-performance fluid handling. Often referred to as the "enhanced version" of C-276, C-22 offers superior protection in environments where both oxidizing and reducing conditions occur simultaneously. This makes it the premier choice for multi-purpose chemical plants and the pharmaceutical industry, where different batches may involve vastly different chemical profiles.

Hastelloy X pipe and tubing are high-temperature structural alloys primarily utilized in the aerospace, petrochemical, and power generation industries. While other Hastelloy grades (like the "C" series) are designed for liquid acid corrosion, Hastelloy X is specifically engineered to maintain its strength and resist oxidation in gaseous environments up to 1200°C (2200°F).

Monel 400 pipe and tubing are the industry standard for high-performance fluid handling in marine and chemical environments. Composed primarily of 67% Nickel and 23% Copper, this "solid-solution" alloy is prized for its ability to withstand rapidly flowing seawater and its legendary resistance to hydrofluoric acid.

Monel K-500 pipe and tubing are high-performance nickel-copper alloys that offer the same legendary corrosion resistance as Monel 400 but with significantly higher mechanical strength and hardness. This is achieved through the addition of aluminum and titanium, followed by a controlled heat-treatment process known as precipitation hardening (age hardening).

Inconel 600 pipe and tubing are high-performance nickel-chromium components designed for service in environments ranging from cryogenic temperatures up to 1095°C (2000°F). While it is prized for its high-temperature oxidation resistance, its most critical feature in piping systems is its near-immunity to chloride-ion stress-corrosion cracking (SCC), making it a much safer alternative to stainless steel in high-risk industrial applications.
