Red-D-Arc was featured in the December/January issue of Tank Storage Magazine in an editorial titled “Rental welding equipment for storage tank fabricators”. Tank Storage Magazine is an industry leading publication, reporting exclusively on the bulk liquid tank storage and terminal sector.
The storage tank construction industry is highly competitive and fabricators gain a significant advantage by leveraging Red-D-Arc’s rental fleet of automatic tank welding equipment. Red-D-Arc supplies specialized automatic storage tank welding equipment to companies in the tank fabrication industry for projects all over the world.
Along with our specialized tank welding equipment comes a highly knowledgeable and experienced team of Red-D-Arc technicians. Sayer Hendricks – storage tank welding equipment specialist at Red-D-Arc is quoted in the article: “A fabrication company without prior knowledge of the equipment, is able to rent a turn-key tank welding automation system and increase their welding productivity by 40-50%. With on-site training, service and support, our customers are up and running quickly and making 100% x-ray quality welds without fail”

An oilfield equipment and vessel manufacturer in the United Arab Emirates approached Red-D-Arc for assistance with a large project. It was awarded to them at the last minute and was not their primary area of expertise. The requirement was to manufacture 25 large tanks with a timeframe of only one year. Each of the tanks was to be 5 meters in diameter by 25 meters long, manufactured using 16 millimeter thick material at a weight of approximately 45 tonnes.
The experienced Red-D-Arc Weld Automation team was able to immediately address all of the customer’s challenges. While other suppliers where insistent that the customer purchase the equipment, Red-D-Arc determined that long term rental would be their best option. This would avoid the time consuming process of acquiring CAPEX approval to purchase such a large amount of equipment and would further increase the profitability of the project. The manufacturer also had questions on how to avoid ovality and transverse movement of the sub-assemblies. Red-D-Arc experts were on-hand to provide the right advice and the right equipment to address these challenges.
The rental equipment included:
• 6x 10 tonne turning roll sets
• 10x 60 tonne drive rolls
• 47x 30 tonne and 60 tonne idler rolls
• 7x submerged arc packages with LT7 tractors and DC600 power sources
Red-D-Arc worked very closely with the company to ensure their success, providing comprehensive training and on-site assistance. After the successful completion of this project the company has become recognized in their market and are receiving new orders from similar customers in the industry. Furthermore, they anticipate being awarded “phase 2” of this project which is scheduled to begin in 2018.
Red-D-Arc’s MFUB-TW Modular Fit Up Bed system is specially designed for the construction of thin-wall tanks ranging in size from 10′ to 15′-6″ in diameter. Our patented system is fitted with independently-adjustable vertical-rolls to support, align and compensate for tank non-concentricity when assembling multiple thin-wall sections. There is no need for spider bracing as the system will keep the cans concentric during fit-up and welding.
Each system is supplied with a Motorized Drive Unit (MDU) module connected to up to four Coupled Connection Drive (CCD) modules – depending on the length and number of sections to be joined. The CCD modules are connected to the MDU module by splice couplings and fish-plates at each side of the skid frame so that the wheel drums on all the modules are driven. The system is flexible enough to accommodate various lengths and sections of tanks. The MDU is driven on both wheel drums through a double-reduction heavy-duty worm and wheel gearbox with chain and sprocket through an AC vectored motor.
Each MDU and CCD module is fitted with 4 hydraulic-support-arms (upper link and lower link assemblies) giving 4 points of contact on each side of the work piece along the length of the fabricated tank. Once the tank section is lowered into position on the wheel drums, the support arms, which independently pivot, are moved into position to manipulate the shape of the tank sidewalls. After the tank sections have been welded together, the support arms – which are independently controlled through a solenoid-operated push-button station controlled via hydraulic power pack – can be disengaged and the tank can be removed.
