Custom Tank Fabrication

The tank and vessel industry consists of boilers, chemical mixing, water storage tanks, other storage, tankers, reactors, water treatment, food preparation, and restaurants.

The experts at KOIKE have worked for decades with top companies in the area of pipe and vessel. Our combination of products and know-how allow our customers to stay ahead of the competition. In particular, our group of KOIKE companies has designed specialized equipment to meet the needs of our customers. The types of cutting and welding done in the pipe and vessel industry require unique solutions for each application. Customers in this business segment require high up time and short turnaround time. Equipment made in this segment can have both very small and large parts, and they can be made of made of steel, stainless steel, aluminum, plastic, or composite.  The large ranges of KOIKE standard and customized equipment are designed to meet the most rigorous demands of our customers.

Cutting machines, such as laser, plasma, oxy-fuel and waterjet cutting, are used to cut parts for flanges, frames, mounting plates, tanks, pressure vessels, and valves.  Our products range from small, one torch cutting machines to large CNC gantry cutting machines with multiple torches. Parts are often made of very thick steel and require specialized bevels for welding in the next stage of fabrication. Large gantry cutting machines have the option to add plasma bevel cutting and oxy-fuel bevel cutting to the machine. Laser and water jet cutting machines can be equipped with three-dimensional bevel cutting heads.

Portable, semi-automated cutting and welding equipment is employed in difficult areas that are often done by hand.  Productivity in these areas can often be increased by three-fold.

The handling of large weldments and parts can be done safely by using positioning equipment, such as gear driven positioners, head and tail stock sets, and turning rolls. Turning rolls and head stock in particular are used to seam pipes and tanks, and to join pipe sections and add flanges to connect manifolds and valves. KOIKE has specialized equipment for building large storage tanks, such as our Automatic Girth Welder (AGW) and our Vertical Up Welder (VUP).  Positioners reduce workload on overhead cranes and other handling equipment. Welds are done more efficiently and defects are reduced. Savings can also be seen in the reduction of wire and gas usage.


"Excellent piece of equipment; easy to setup and use."
