Spheres

Discover the Spheres Advantage at Conrex Steel

In the continuous pursuit of expanding our capabilities, we have taken our knowledge and expertise in segmental multi piece forming and applied it to the manufacturing of aboveground storage tanks (ASTs) or more specifically “pressure spheres”. Spheres are widely used for the liquid storage of gaseous materials; they offer excellent internal stress distribution making them a very efficient option for pressurized storage.

• We’ve supplied materials and fabrication for over 60 spheres of various sizes, material grades (including stainless steels), and thicknesses.
• Conrex can form either an Orange Peel design or Soccer Ball design. 
• We can form the outer shell or inner shell/liner for any sphere in a multitude of metals (Clad, stainless, carbon, etc.)
• Our capabilities include two large capacity presses and new automated gantries. This  provides continuous material flow. We can also hot form steel plates, utilizing two large heat-treating furnaces and two nine axis plate trim and bevel burning machines.
• In conjunction with our key partners, we have the ability to produce storage spheres with little restriction on size.
• The reduction of pieces and footage of weld, provides you with the most cost-effective solutions, while ensuring high quality and just-in-time delivery.
• We also provide surface preparation, such as shot blasting.
• We provide specialized pressing and fabrication capacity to pre-fabricate and ship sphere sections (as required in the field); with direct access to all states, provinces and countries using either trucking, ships (containers) or rail.
• From liquefied natural gas (LNG), propane, butane, petroleum and other large volume storage needs, we have the unique solutions to cater to a wide variety of industries across the globe.

Using the C-Press in conjunction with the Gantry Cranes, Conrex has a unique one person operation with combined controls

Conrex can fabricate both the Orange Peel and Soccer Ball designs in the Sphere marketplace. The Soccer Ball cap requires a more sophisticated bevel program.
