Since 1967, WMP has been a global leader in the manufacturing of specialty process tower internals, and we maintain an extensive on-hand inventory of tray and reactor hardware and a wide range of steel alloys to provide plant and contractor field operations outstanding response for emergency hardware and fabricated internal requirements. WMP provides the process industry complete replacement-in-kind tower internals, regardless of original equipment manufacturer, and engineered internal solutions for all existing, upgrade and new tower internal applications.

WMP works with you to create or review engineering drawings in order to meet your specifications prior to beginning production on internal components. We have a variety of materials always in stock that enable us to complete complex jobs within tight timelines. This makes WMP a great partner for any refinery, installation company, turnaround company, chemical plant, engineering group or others that need assistance along the way. WMP understands that when internals are needed, it could mean critical processes have stopped or a plant has been shut down. Customers and partners have come to rely on WMP for our expediency, quality work and attention to detail.
