Induction Bending Technology

Induction Bending Technology

A company with history For more than 50 years company AWS Schäfer Technologie GmbH is constructing machines for pipe forming and put more than 3000 machines worldwide into operation since the foundation. The first hot bending machine for pipes has been attempted in 1980. From that time we constantly upgraded this technology and today we deliver machines for highest bending requirements. The induction bending technology by AWS SCHÄFER provides enormous advantages in comparison to conventional bending methods: Bends with different radii and bending angles Bends with reduced ovality SRBMI 1400, Pre-acceptance in our works Bends with slight wall thickness reduction Multiple bends with straight branches, less welding connections Bends with reduced examination effort Bends of ferritic and austenitic steels as well as Duplex materials Cooling at resting air Maintenance-optimized operation and highest availability Bends with complex geometries Low energy consumption with high efficiency Reduced modification and handling times Bends with smallest R/D-ratios SRBMI 600, Watercooled bending 2

Our company s philosophy We work out concepts together with the customer and meet the individual requirements. We provide the right machine construction and equipment for each application. We solve individual bending tasks by an efficient machine program Technical Dates Pipe diameter ( Ø ) 50 1.660 mm ( 2 65 ) Wall tickness ( t ) 3 120 mm (0,1 4,7 ) Radi ( R ) 75 10.000 mm (3 394 ) Bending angle ( ) 1 183 Feeding force ( Pv ) 400 5.000 KN Bending moment (MB ) 550 10.000 KNm Inductor power Inductor frequency Pipe length 100 1.600 KW 50 10.000 Hz up to 18 m 3

Progression that never stands We are constantly investing in the development to fulfil the high standards of our customers. Ovality Pipe material S355 - P92 Austenitic Steels Ferritic Steels Duplex Super Duplex Pipe Round or square from 50 mm up to max. 1.660 mm Bending radii from 1,36 x D up to 10 m Bending speeds From 1-150 mm/min 4

Technology for highest bending quality Ovality at 1,5 x D 4 % at D/t > 30 possible Ø 406 x 70 mm Bending without water cooling Wall thinning at 1,5 x D < 12,5 % possible Bending angle tolerances +/- 0,5 Automatic Angle Rotation Device Exact bending results with constant repeatability Bending angle up to 183 without additional set-up costs Absolute positioning accuracy, even at max. bending moment and load change Low maintenance costs Automated START-STOP operation for soft transitions of the wall thickness Ø 406 x 9,8 mm Bending 180 R=650 R = 1,36 x D Bend 10CrMo910, Ø 406 x 70 mm, Ovality 1,48% Wall thinning 8%, deviation 0,2 Temperature difference pressure-tensile area 200 Optimized set-up times by pipe manipulator for loading and unloading the pipe Reduced foundation costs due to intelligent force redirecting in the machine construction SRBMI 800, asymmetric pipe clamping in the bending head 5

Benefit from our Know-How We take up a lot of time for our customers and advise them competently and qualifiedly at the purchase of a machine. During a detailed demonstration of induction bending machines in our works our customers may convince themselves of the strengths of our machines already before delivery.
