Abstract: Systems and methods for manufacturing high-strength cladded components such as pressure containing components that may be used in, e.g., oilfield systems to carry corrosive fluids at high pressures. Embodiments of the invention include products and processes in which low carbon HSLA Steel that has a yield strength greater than 70,000 psi is used as a base material from which a component is formed. A corrosion resistant alloy is welded to selected surfaces of the base metal. Because the base material has a low carbon content, welding the corrosion resistant alloy onto the base material does not create significant stresses in the base material and consequently eliminates the need for PWHT to relieve such stresses and eliminates strength degradation that normally results from PWHT. Eliminating PWHT also allows the component to be refurbished and re-cladded multiple times without significantly degrading the yield strength of the component.

Abstract: A railing connector for mounting a railing to a post, the railing connector comprising a sleeve for receiving an end of the railing, and a flange extending from the sleeve for attachment to the post.
Abstract: A gasket retention system and flange coupling has a ring gasket that disposes in seal seats on opposing flanges. One or more retainer tabs extend from an outer periphery of the ring gasket. Preferably, the ring gasket defines a slot on the outer periphery, and the retainer tab affixes with an interference fit in the slot to be held therein. The retainer tab defines a transverse opening therethrough. When the ring gasket fits into the seal seat of one of the flanges, the transverse opening of the tab fits onto a fastener affixed in a pre-drilled hole in the face of the flange.
