All-electric Tube Benders Take a Step Forward

Unison's new machine brings the flexibility of all-electric pipe bending technology to large pipe sizes. Among many possibilities is the means to fabricate long and complex pipe shapes in single pieces.

The tube bending machine innovator Unison said it is moving the technology forward again, with the completion of a groundbreaking all-electric machine that is capable of bending tubes and pipes up to 9 inches/225 mm in diameter. The availability of all-electric machines at this new size level brings the benefits of instant set-up and right-first-time precision bending to many new applications in sectors including shipbuilding, powergen and oil, gas and chemical processing. According to Unison…

Tube bending machine manufacturer, Schwarze-Robitec has opened a North American subsidiary as of April 2015. Schwarze-Robitec America Inc. has been implementing the entire sales and service for the high-quality Tube Cold Bending Machines Made in Germany. Customers from the USA, Canada and Mexico benefit from the customer-specific on-site advice, shorter delivery times for spare parts and attractive conditions. Schwarze-Robitec, founded in 1903, is the leading manufacturer of Tube Cold Bending Machines.

CNC Tube Bending Machines from Schwarze-Robitec

The CNC 320 HD tube bending machine allows extremely small bending radii (1.5 x tube diameter) – even for large tubes and pipes with very thin walls and diameters up to 323.9 millimeters.

Speed, volume and size of container ships are constantly increasing to facilitate international transport of growing quantities of goods. At the same time, shipyards are facing increasingly intense global competition. In Europe, the USA, Asia and even Australia, there is competition for customers from civilian and military shipping. In view of these developments, the focus is on the production processes in the shipyards: the motto is “greater speed, greater flexibility, greater efficiency”.

Schwarze-Robitec Offers Efficiency in Shipbuilding

Cruise ships, freighters or yachts require complex supply systems on board to  be able to travel long distances in the open sea. For the supply of oil and gas, for example, many kilometers of pipelines are installed above and below deck. To optimize the limited space available inside the ship, the bending radii of these pipes must be kept very tight. Therefore, shipbuilders require systems that enable the production of pipes with very small bending radii. To meet this demand, Schwarze-Robitec developed the pipe cold bending machine CNC 220.

Tube Benders Speed Subsea Wellhead Construciton

All-electric tube bending machines from Unison are helping FMC Technologies - the leading supplier of subsea tree hydraulic control systems for wellheads - to substantially reduce build times and multiply its manufacturing capacity. Six sites worldwide now use Unison tube bending machines in a new production method pioneered by FMC Technologies employees in Norway and Scotland. The subsea systems supplier used to plan the routes for the hydraulic tubing runs that interconnect the valves and other component parts of the subsea trees…

Unison has received an order from Newport News Shipbuilding (NNS), the supplier of nuclear-powered aircraft carriers and one of two shipbuilders of nuclear-powered submarines for the U.S. Navy, for an all-electric CNC machine capable of bending large-bore tubing and piping up to eight inches in diameter (219mm OD). The machine will be the first of its type ever built, extending the shipbuilder’s range of precision software-controlled bending facilities to include fabrication of larger diameter pipes that previously could only be bent on very high torque hydraulic machines.

Siemens Subsea Products Adopts All-Electric Tube Bending

Siemens Subsea Products has chosen an all-electric tube bender from Unison to improve the quality and speed the production of the small-bore hydraulic tubes it uses on subsea hydraulic flying leads with Multiple Quick Connections (MQC), Cobra Heads and associated offshore oil and gas recovery equipment. The tubes feature complex bends of extremely high accuracy, and until now the company has either fabricated them manually or bought them in as pre-formed sub-assemblies. Siemens Subsea Products produces a wide range of subsea electric…

Largest All-Electric Pipe Bender Starts Operations at Newport News Shipbuilding

Unison has commissioned what is believed to be the largest all-electric tube bending machine ever produced. The machine has started operations at Newport News Shipbuilding, supplier of nuclear-powered aircraft carriers and submarines to the US Navy. The machine is capable of generating over 265,000 lb-ft (360,000 Nm) of torque and can bend piping up to 8 inches NPS - with an outside diameter of 8.625 inches or 219.1 mm - with Schedule 80 wall thicknesses of 0.5 inch (12.7 mm). The availability of all-electric, servomotor-controlled bending machines for pipes of this size brings significant productivity benefits to the fabrication of a ship's pipework compared with conventional hydraulically-powered machinery.

SBM Offshore Announces Thunder Hawk Tiebacks

SBM Offshore is pleased to announce it has signed a Production Handling Agreement (PHA) with Noble Energy to produce the Big Bend and Dantzler fields to the Thunder Hawk DeepDraft (TM) Semi located in 6,060 feet of water in the Gulf of Mexico (GoM). Production fees associated with produced volumes are estimated to lead up to projected revenue of US$400 million to be delivered over the ten year primary contract period. First oil from Big Bend and Dantzler are expected in late 2015 and first quarter 2016 respectively. At these levels both fields will utilize a maximum of 85% of total daily asset capacity, and brownfield construction to upgrade the facility will be handled by Noble Energy.

Norfolk Naval Shipyard Adds New Pipe Bending Machine

Capturing complex bends on pipes is an art form members of the Norfolk Naval Shipyard (NNSY) Pipe Group have harnessed for many years. Now entering a more modern era with a new dual-head pipe bending machine, NNSY is able to create more precise bends in a fraction of the time, thanks to modern, automated controls. Originally, pipe benders would have to work on a semiautomatic machine where everything would have to be measured exactly and each bend would have to be checked with a protractor to guarantee the needed dimensions were captured. It was tedious work and there was a risk of wasted material should the measurements not equate to what was needed.

UK Shipyard Orders Second Tube Bender

A second state-of-the-art tube bending machine has been ordered by BAE Systems Submarine Solutions to support the construction of the UK's Astute class nuclear-powered submarines. The new tube bending machine is an all-electric model with precision software-controlled servomotor movement, for bending tube diameters up to 76 mm. It also features an advanced laser measurement system that monitors any deviations to the programmed bend caused by the tubing material's 'springback' characteristics, and then automatically adjusts the bend to produce the correct shape. These features equip BAE Systems to handle the very demanding workload of the Astute submarine program.

Hydrex Performs Underwater Propeller Blade Straightening

In April, a diver/technician team performed propeller blade straightening operations on two vessels at anchorage in Kalundborg, Denmark. First the bent blades of a 225–meter bulk carrier were restored. The team then straightened the damaged blades of 158-meter reefer in the same location. By taking advantage of the in-house developed cold straightening technique, damaged blades can be straightened underwater. This allows a ship to return to commercial operations without the need to drydock. Optimum efficiency of the propellers can be restored by bringing the blades back to their original form.
