Construction

A335 P91 alloy steel pipe is a high-performance, high-temperature and corrosion-resistant alloy steel pipe, which is widely used in petroleum, chemical industry, electric power and other fields.

EN 10219 S275J0H hollow section pipes are mainly used in outdoor steel fields such as building structures, bridges, vehicles, ships, containers, power plant chimneys, and railway engineering.

ASTM A333 and ASTM A334 are both specifications for seamless and welded carbon and alloy steel pipes used for low-temperature service. Specifically, ASTM A333 covers a range of steel grades suitable for temperatures as low as -50°F (-45°C), while ASTM A334 is intended for temperatures as low as -150°F (-101°C).

EN 10297-1 is a European standard that specifies the technical delivery conditions for seamless round steel tubes for mechanical and general engineering purposes, including non-alloy and alloy steel tubes.
