A334 GR.7 Round Steel Pipe

GNEE sells over 1,500 tons of seamless and welded steel pipes to various engineering industries annually. Our goal is to ensure that our customers have the highest expectations for A334 GR.7 carbon steel pipe delivery and product quality.

A334 GR.7 is a carbon steel pipe whose composition includes carbon, manganese, silicon, molybdenum, nickel and other elements. The carbon content is 0.19%~0.24%, and the manganese content is 0.90%~1.35%.
The advantage of A334 GR.7 cryogenic pipe is that it has good low-temperature toughness, is suitable for use in low-temperature environments, and has good corrosion resistance. Since A334 GR.7 alloy pipe has added molybdenum and nickel elements, it can work stably in corrosive media.
A344 GR.7 low carbon steel pipes are commonly used in liquefied natural gas storage and transportation equipment, liquefied petroleum gas storage and transportation equipment, low-temperature air separation equipment, etc.
