WORK STATION FOR VALVES ASSEMBLING/DISASSEMBLING PURPOSE: • RMR-4, RMR-5 - disassembling and assembling of the wedge, stop, control, and shut-off valves. • RMR-4-1 - disassembling and assembling and performing preliminary pneumatic tests of the wedge, stop, control, and shut-off valves at a pressure of up to 6 bar (90 psi). • RMR-6 - disassembling and assembling of the wedge and parallel-seat gate valve. • RMR-PPK - disassembling and assembling of the safety valves. • RMR-SH - disassembling and assembling of the slab gate valves. • RMR-AFK - disassembling and assembling of the wellhead...

PURPOSE: • unit is designed for nuts unscrewing, screwing, and cutting (where it is impossible to unscrew). • trolley; • high-pressure hoses; • pump station; • hydraulic nut socket driver; • hydraulic nut splitters; • hydraulic hand pump. ADVANTAGES: ■ The set includes the tools required for disassembly and ■ Nut cutters ensure simple and safe removal of damaged assembly of threaded joints, which do not damage the and rusted nuts, which cannot be unscrewed (removal of threaded surface of bolts or stud bolts. one nut takes about two minutes). ■ When requested by customer, it can be...

MACHINES FOR HARDFACING/OVERLAYING OF PIPELINE VALVES PARTS PURPOSE: • automated hardfacing/overlaying of pipeline parts and elements with diameter from 50 up to 1200 mm (2...48") with or without electrode oscillation with submerged arc process or in an atmosphere of shielding gases (MIG/MAG processes) with full wire. ADVANTAGES: ■ The machines are fitted out with forced cooling of the welding unit and a set of water-cooled welding heads. ■ The electrode oscillating mechanism allows to increase the width of the overlayed seam up to 60 mm (2%"). ■ Advanced construction of rotator allows to...

automated hardfacing/overlaying of shafts, spindles and rods with diameter of up to 400 mm (16") with consumable electrode in an atmosphere of shielding gases (MIG/MAG/TIG1 processes) ■ The machine is completed with forced cooling welding head and bended water-cooled burner for welding of fillet welds. ■ The machine allows hardfacing/overlaying of cylindrical workpieces with length up to 1250 mm (49"). ■ The control system of the machine is implemented on the basis of industrial controller, which allows the operator to set the parameters of welding (range of oscillations, velocity of the...

• girth seam welding of pipeline parts with diameter from 15 up to 1400 mm (14 ... 56") with MIG/MAG process. ADVANTAGES: ■ Simultaneous operation of two welding heads provides high performance of the unit. ■ Standard set of the units includes: rotator, gantry, two welding heads and two welders. ■ Tilting rotator face-plate. ■ Continuous adjustment of welding speed. ■ Control systems of the units are based on industrial controller, thus allowing operator to set welding parameters (welding speed, number of faceplate revolutions etc.) while using touch sensitive control panel. ■ The welding...

MACHINES FOR HARDFACING/OVERLAYING OF CYLINDERS PURPOSE: • automated hardfacing/overlaying of the external and internal surfaces of cylinders with consumable electrode in an atmosphere of shielding gas or by flux-cored wire (MIG/MAG). UNG-750-400-400-KNV-А ADVANTAGES: ■ Compact size. ■ The control systems of the machines allows to program the unit to perform hardfacing/overlaying of several types of parts. ■ The hardfacing/overlaying process may consist of several passes with different overlaying rate, the presence of transverse oscillation, different oscillation parameters (range, speed...
