The first design is the Bolted Bonnet, with male-female joint, spiral wound gasket, made in F304/graphite.Ring joint gasket are also available on request. The second design is the welded bonnet, with a threaded and seal welded joint. On request a full penetration strength welded joint is available .The third design is the pressure seal bonnet, with a threaded and pressure seal bonnet joint.

When discussing the strength of forged or milled steel parts, grain flow refers to how the molecules in the metal are aligned. Although not as visible, grains in a piece of steel are like the wood grain in a piece of lumber. The grain flow determines the strength of the metal piece.For engineered steel pieces, manufacturers and engineers identify the direction of the grain flow to evaluating the piece's design characteristics and strength.
