Butt welding fittings are manufactured in accordance with ANSI B 16.9 for dimensions and tolerances, ANSI B 16.9/B 16.25 for end preparation as well as ASTM A 403 or other applicable Standards for manufacturing and testing requirements. Fittings can also be manufactured conforming to customer specifications.
