Russian producer of API grade pipe selects Thermatool

The pipe mill has a length of more than 450m, and includes various facilities for testing the large pipes according to API standards. Ultrasound, X-rays and pressurised water are used for this process. The mill from Schuler will increase Tuberías Procarsa’s production capacities by 220,000 tonnes per year. Schuler offers presses, automation solutions, dies, process technology and service for the entire metalworking industry and lightweight automotive construction. Clients include car manufacturers and their suppliers, as well as companies in the forging, household equipment, packaging, energy and electrical industries. Thermatool Variable Inductance Power (VIP) power supplies provide optimised matching to thin and heavy wall. API pipe and each power supply can be independently controlled from one single, central console. Commissioning is scheduled for early in 2015.

untempered martensite in the weld HAZ and optimised weld section Charpy impact results for demanding material applications. The well proven precision automated carriage positioning system ensures that all three heat stations can be quickly adjusted to position the inductors over the seam of the pipe both laterally and orbitally to ensure maximum yield and minimised scrap created after a mill stop. Reliably delivered power comes from industry-leading VIP induction power supply technology.

ATHERMATOOL three-stage (1,500kW) seam annealing system has been selected by one of Russia’s leading producers of API grade pipe. The latest Thermatool seam annealing technology will be delivered by Inductotherm Group company Inductotherm Heating & Welding Ltd of the UK, with commissioning and service support provided locally by Inductotherm Group Russia engineers. With hundreds of Thermatool seam annealers used to produce API line pipe and casing products around the world, Russian producers are assured of no

Major order for spiral pipe mill SCHULER has received a major order for delivery of a spiral pipe machine, from a manufacturer of steel pipes in Mexico. Tuberías Procarsa will use the off-line machine to produce large pipes with diameters from 508 to 2,235mm (20" to 88") and lengths from 12 to 24.4m. The pipes will mainly be used for building pipelines in oil and gas extraction. The input stock for the large pipes is a coil-wound strip up to 25.4mm (1") thick, comprising high-grade steel (up to X100). The spiral pipe machine forms this material into the required pipe diameter and connects the edges by tack welding. Welding of the pipe is then completed on a separate welding stand using the submerged-arc method.
