A283 GRA spiral steel pipe is a material grade of low carbon steel plate, usually used to manufacture some ordinary structural parts. SSAW steel pipe is a spiral submerged arc welded steel pipe suitable for various liquid transportation, natural gas, petroleum, structural support and other engineering fields.
A283 GRA SSAW steel pipe refers to spiral submerged arc welded steel pipe made of A283 GRA material. This type of steel pipe is commonly used in general structural engineering, construction, and liquid transportation piping.
The wall thickness of A283 GRA welded pipe is usually between 3mm and 20mm, and the specific value depends on the required pressure level, transmission medium, environmental conditions and engineering requirements.
