Throughout the entire manufacturing process of ward unions, special emphasis is placed upon the control and accuracy of each operation. Ward unions are made from closely grained, high tensile iron and are produced under expert laboratory supervision. Modern methods of foundry practice and carefully supervised molding are combined to produce castings that are smooth and clean in every respect and free from imperfection. Ward unions are manufactured in strict accordance with the requirements for threaded pipe unions standard, developed by American society of mechanical engineers (ASME) and published as an American national Standard. Each opening is chamfered permitting easy assembly. Ward unions make up easily and pull tight for a sealed assembly. Continuous and careful inspection by trained employees during and after each operation produces quality products which will give satisfaction to the user.
