Liam Pipes and Tubes is a trusted manufacturer and supplier of Stainless Steel 321/321H Heat Exchanger Tubing, proudly based in Houston, USA. Renowned for their precision engineering and unwavering quality, Liam delivers tubing solutions that adhere to strict industry standards. Their Stainless Steel 321/321H heat exchanger tubes are crafted to excel in high-temperature and corrosive settings. With state-of-the-art manufacturing facilities and a strong focus on customer satisfaction, Liam caters to a variety of sectors, including chemical processing, oil and gas, power generation, and marine applications, making them a go-to choice for durable and efficient heat exchanger tubing solutions throughout the USA.
The Stainless Steel 321/321H Heat Exchanger Tubing is primarily made up of chromium (17–19%), nickel (9–12%), and is stabilized with titanium to prevent intergranular corrosion. The 321H variant features a higher carbon content (0.04–0.10%) to boost its strength at elevated temperatures. These tubes showcase remarkable resistance to oxidation and creep at temperatures reaching up to 900°C. Their mechanical properties include a tensile strength of around 515 MPa, yield strength of 205 MPa, and an elongation of about 40%. This unique composition and performance make the tubing ideal for high-pressure and temperature-sensitive applications.
