Pipe & Vessel
The pipe and vessel industry consists of boilers, chemical mixing and 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 have designed specialized equipment to meet the needs of our customers.
Longitudinal seam welder provides accurate cylinder manufacturing that is simply and cost effective to operate.
Internal, external and flat plate seamers are available and can be customized depending on length , diameter and thickness required for each specific application.
The types of cutting and welding done in pipe and vessel require unique solutions for each application. Customers in this business segment require high up time and short turnaround time. Equipment made within this segment can have both very small and large parts, and they can be 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 the use of positioning equipment, such as gear driven positioners, headstocks and tailstock sets, and pipe turning rolls. Turning rolls and headstocks are used to seam pipes and tanks, as well as joining pipe sections and adding flanges to connect up manifolds and valves. 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.
