How to Select Tubing for High-Pressure
Introduction In high-pressure systems, tubing failure isn’t just costly—it can be catastrophic. Whether you’re building an offshore platform, a hydraulic power unit, or a supercritical fluid system, choosing the right tubing is critical. This guide breaks down the key factors to consider when selecting high-pressure stainless steel and alloy tubing, including pressure rating, material strength, […]
Read MoreNickel Alloy 625 vs 825: Choosing
1. Introduction When it comes to critical piping systems in chemical plants, refineries, and offshore projects, material selection plays a decisive role in long-term reliability. Two of the most widely specified options are Nickel Alloy 625 pipes and Incoloy 825 tubes. Although both are high-performance alloys with excellent corrosion resistance, their properties and cost-performance profiles […]
Read MoreStainless Steel Tubes for Hydrogen Production
Hydrogen production systems need reliable tubing and piping materials. In electrolysis plants, hydrogen generators, balance-of-plant systems, cooling loops, gas-water separation units, purification systems, compressors, and hydrogen skids, tubes may be exposed to high-purity water, oxygen, hydrogen, alkaline electrolyte, acidic environments, pressure, temperature changes, and strict cleanliness requirements. Stainless steel tubes are widely used in hydrogen […]
Read MoreTitanium vs Stainless Steel Tubes for
Titanium tubes and stainless steel tubes are both used as heat exchanger tubes in many industrial systems. But they are not used for the same working conditions. Titanium is often used in seawater, high chloride, desalination, and marine systems. Stainless steel is often used in general heat exchangers, boilers, power plants, chemical plants, and cost-sensitive […]
