Applications of various qualities:
Different types and grades of steel tube profiles are used depending on the technical requirements of a project. Below is an overview of common grades and their typical applications:
-
Grade B
Suitable for general applications in low to medium pressure systems, such as water pipes, constructions, and light industry. - 4130
Used in applications with high strength requirements, such as drilling, cranes, rock-breaking machinery, and parts in the oil and gas industry. -
A106 Gr. B
Used in high-pressure and high-temperature applications, such as steam pipes, oil and gas transport, and boiler systems. -
A333 Gr. 6
Specially designed for low-temperature applications, such as in cryogenic installations, refrigeration technology, and offshore constructions. -
P235 / P265
Commonly used in pressure vessels, heat exchangers, and general structural applications in the (petro)chemical industry and mechanical engineering.
