The next wave of pipe seam submerged arc welding

maintaining an optimal production process. Emergence wire doubles the life of contact tips, resulting in consistent arc starts, wire placement and weld deposit, and less downtime and lost production due to frequent change outs. Emergence is part of a comprehensive product line to support every pipe seam application. The exact wire composition of Lincoln Electric’s copper coated wires makes requalification for welding procedures controlled by classification easy.

LINCOLN Electric has developed Lincolnweld ® Emergence to help welders avoid common processing flaws that can lead to costly repairs and excess scrap. Lincolnweld Emergence is a non- copper coated submerged arc wire with a proprietary surface treatment to protect material and perform the same as copper coated wires in the same alloy class. It also improves wire conductivity over competitive non-copper coated wire. The elimination of surface copper in Emergence decreases the risk of weld contamination. The right selection of contact tip and wire is critical to

Enhanced coupling makeup machines WITHIN its product ranges for oil and gas pipe finishing lines, Lazzari has improved the design and technical features of its high-productivity Coupling Makeup machines (CM), in order to meet the latest requirements of API standards for quality and increased performance. All components of the CM series machines have been redesigned and improved to allow a fully automatic complete cycle to apply couplings on tubing and casing pipes up to 508mm (20") nominal OD, up to a maximum torque of 130,000Nm in the case of special Premium coupling types. the whole pre-screwing and screwing operation, recording the graphics of the coupling final screwing with automatic working cycle with torque priority or position priority. The machine operator works from a touch panel, guided by an icon system, to manage the receipt of pipes and machine data, as well as machine diagnostics and alarms. The machine mainly consists of a robot to load the couplings directly from the coupling container, a storage chute for the coupling measurement and for the dope application on the coupling thread, starter unit, screw-on unit, short drifter unit, pipe transfer unit by rotating arms, a set of durable tooling, The machine controls and measures the values of torque and turns during

and auxiliary hydraulic and electrical equipment. The equipment to be supplied is manufactured with high quality materials and components, ensuring long-life performance and reliability. Lazzari also guarantees efficient supervision to the erection and putting into operation at the buyer’s site, as well as constant assistance through online connection and availability of the service of its technicians.
