TIANJIN Zhongshun Petroleumsteel Pipe Company is a large-scale manufacturer specialising in the production of ERW steel pipes and DSAW steel pipes. With investments totalling US$37mn, the company operates from a base of over 300,000m 2 and produces 600,000 tons of welded steel pipes annually. Advanced equipment used in the company’s pipe production includes three Many kinds of coating can also be applied, such as FBE, 2PE, 3PE, 2PP, 3PP, epoxy coal asphalt, internal epoxy coating, and cement mortar lining.

The mills can produce longitudinally welded steel pipes ranging in diameter from 21.3 to 457.2mm with wall thickness ranging from 1.8 to 14.27mm, and spirally double-sided submerged arc welded pipe with diameters ranging from 219 to 3,040mm and wall thickness ranging from 5 to 30mm.

ZUMBACH Electronic AG has recently extended its range of STEELMASTER rod and bar gauges by a further and bigger model. The new gauge, SMO 160-S6, is equipped with 6 high-speed laser scanners ODAC ® 160 and delivers up to 6000 measurements/s i.e. 1000 processed profiles/sec. It also features Zumbach’s calibrated single scan system (CSS) and the unique EPM method and software (patent pending). The gauge is able to measure rounds, hex, squares, flats and various shapes with outside dimensions up to approx. 140mm (dep. product vibration) in multiple modes: static, orientable mode: measures in 6 directions, 30 degrees spaced; partial oscillation mode: programmable start and stop angle, e.g. for squares or flats; full 180° oscillation: standard mode for rounds, every 30° rotation delivers a full profile. The EPM method and software, in combination with CSS, makes the gauge an effective tool at 3 roll blocks or when the bar has polygonal or asymmetric shape deviations – asymmetric underfill or overfills. It calculates the typical values DT and GT for the initial roll settings. It can also calculate and display “Roundness” RON t according the official ISO definition for any shape. The mechanical system is the same as the well proven design of the smaller gauges and requires minimal maintenance resp. periodic cleaning only. Smaller gauge models for wire rod and smaller sizes are also available. Zumbach Electronic AG – Germany
