ASTM A795 Grade B
ASTM A795 Grade B
ASTM A795 Grade B Carbon Steel Pipes is one of the most commonly used for general purpose applications worldwide. ASTM A795 Grade B Pipes are ductile and strong Pipes with long-wearing properties. These Pipes are manufactured as per ASTM specifications.
The ASTM A795 Grade B specification applies to welded and steel pipe in diameters ranging from NPS 1/2 to NPS 10. Pipe with different wall thicknesses may be supplied as long as it meets all of the other requirements of this standard. TUSPIPE will generate a recommended pipe size after receiving your inquiry. To create the best tubing for the ultimate application, grade, chemical analysis, and surface condition are carefully studied, and production procedures are adjusted.
