Openex has years of experience fabricating both large and small pressure vessels including:
Openex provides turnkey services from machining, fabrication, blasting, painting and delivery internal trays of columns & towers for our customers. The fabrication process is carried out under strict adherence to international standards. Openex successfully manufactured and delivered one of the world’s largest single piece process columns, the Propylene-Propane Splitter for a Propane Dehydrogenation Plant. Since then, Openex has manufactured and delivered many columns and towers of up to 13 m diameter with over 100 m length and weighing 1,000 T to many of its customers worldwide.
Openex’s strength is its ability to manufacture such large, heavy and long column & towers to any international codes and standards. Openex’s unique capability is to perform PWHT of columns and towers with no restriction in size under one single firing which is a rare feat. Openex also offers its customers a one stop centre to include installation of material trays and insulations if required.
Openex offers a variety of reactors for the Oil, Gas and Petrochemical industries. Some of these reactors are made of high grade steel such as Carbon Steel, Superduplex, Crome Molley, Incoloy and etc. Openex past records for reactors include but not limit the ones listed as following.

Openex manufactures separators for oil & gas industries. A separator for petroleum production is a large drum designed to separate production fluids into their constituent components of oil, gas and water. Openex's separators work on the principle that the three components have different densities, which allows them to stratify when moving slowly with gas on top, water on the bottom and oil in the middle. Any solids such as sand will also settle in the bottom of the separator.
Gas can be removed from the top of the drum by virtue of being gas. Oil and water are separated at the end of the separator, which is set at a height close to the oil-water contact, allowing oil to spill over onto the other side, while trapping water on the near side.
Openex has deep understanding on the mechanical and thermodynamics engineering expertise for this product. Steam drums are a regular feature in many boiler systems. The steam drum provides a space for the saturated steam generated in the tubes and for the separation of moisture from the steam. It is a reservoir of water/steam at the top end of the water tubes in the water-tube boiler. Steam drums store the steam generated in the water tubes and act as a phase separator for the steam/water mixture.
Jacketed vessels are pressure vessel with a second pressure container ( the jacket ) applied generally to the outside of the pressure vessel shell itself, to either provide cooling or heating to the vessel contents. Openex manufactures jacketed vessels using dimple jacket walls technology instead of the more conventional half-pipe, coil and double wall configurations. This allows to use less weight, to have a better heat transfer efficiency, to withstand large temperature differences and to follow different shapes of the pressure vessel shell. For these reasons Openex jacketed vessels are recommended for critical applications.
Cryogenic vessels are tanks designed to keep an internal temperature lower than -73.3°C (-100°F). These vessels may be used to store a variety of fluids such as oxygen, argon, nitrogen, and helium or as high vacuum (HV) or ultra high vacuum (UHV) chambers for testing and research purposes. Openex manufactures a number of different cryogenic vessels made from stainless steel or special materials such as hastelloy and aluminium and based on the application of the dimple –jacket wall technology.
This product is widely used especially where dissolved oxygen is available after a process, where it is absolutely necessary to remove the dissolved oxygen and to protect the inner part of equipment from severe corrosion. Openex manufactures deaerators for a wide spectrum of application, in accordance to specification provided by clients.
Openex is very experienced in the design & fabrication of autoclaves for the minerals processing industries. We have supplied equipment from solid duplex stainless steals through to titatium clad vessels.
