The Role of A516Gr70 in Petrochemical Equipment

A516Gr70 steel is a key material in petrochemical industry applications, particularly in pressure vessels, towers, reactors, and heat exchangers.

A516Gr70 steel's ability to withstand high pressures and temperatures above 200°C, combined with excellent toughness, makes A516Gr70 steel ideal for critical infrastructure. Thick sections over 100mm remain consistent in properties, allowing safe construction of large towers and tanks.

The grade supports multiple welding methods, with a stable heat-affected zone that reduces failure risk. A516Gr70 steel is available with certifications such as ASME, NACE MR0175, and EN10204 3.2, making A516Gr70 steel a go-to steel for refinery projects in the Middle East, Southeast Asia, and large-scale domestic chemical plants.
