Who we are
Built for the
work.
Houston Process and Design (HPD) is a Houston-based manufacturer of custom pressure vessels, filter housings, strainers, and vessel internals. We build ASME Section VIII, Division 1 pressure vessels for petrochemical, water, food-grade, and other process applications, with each project built to the customer’s specifications.
Design and engineering, welding, fabrication, and machining are all handled in-house. Our engineers and shop teams work directly with one another on the details that matter—from nozzle layouts and machined closures to basket fit and removal access. Customers can work with one manufacturer on both the vessel and the components inside it.
Our Houston operation includes dedicated carbon steel and stainless fabrication buildings, a full-service machine shop, and a staffed baskets and internals department. We build complete assemblies as well as replacement internals for vessels made by others, giving customers a fabrication partner for new equipment and the equipment already in service.

Our Houston operation
Room to build. Control to deliver.
Our Houston site brings dedicated carbon steel and stainless fabrication buildings together with a full-service machine shop. Turning, milling, boring, and CNC capability support machined components, closures, and vessel internals, coordinated directly with fabrication and fit-up. Across both shops, 20 jib cranes support material handling, fitting, and fabrication in addition to our overhead cranes.
