ASTM A795 Grade A
ASTM A795 Grade A
ASTM A795 Grade A refers to a kind of steel pipe. ASTM A795 welded steel pipe is available in two grades (Grade A and Grade B) and three kinds (type E, type F, and type S). The ERW (Electric Resistance Weld) technique is represented by Type E. ASTM A795 type E Grade A is a widely utilized type that has been widely used for pipe sprinkler systems.
TUSPIPE, one of China’s leading suppliers and manufacturers of carbon steel pipes, provides the ASTM A795 type E Grade A steel pipe piling and related pipe fittings used for fire main pipe, fire pump pipe, fire standpipe, and fire sprinkler branch pipe. Comprehensive sophisticated coating measures are given for your pipe demands thanks to the collaboration of China’s main steel mills.
