Bead removal technology from EPI

EPI’s bead remover has been developed to remove bead on the top and bottom of the strip by milling at the same time. Under the strict and non- compromised customer’s inspection, the bead remover has shipped to Japan successfully with finishing floor equipment, inside bead flusher (IBF), end facing and bevelling M/C and bundling M/C for 5.5" ERW line. EPI, which is a joint venture company of Nakata, is preparing the patent. As a leader in forming technology (FFX and ODF), Nakata supports and gives an opportunity to EPI to develop

THE largest ERW pipe producer in Japan, Nisshine Kokan, has awarded EPI an order to supply a bead remover. The bead remover from EPI not only increases the yield but also decreases the damage of forming rolls. Top and bottom bead after the butt welding of strip is a burden on the production of an ERW line. The bead impacts on the stand and scratches forming rolls. To remove the bead after coil joining, the operator grinds the bead by manual skill or using a bead remover. Most bead removers operating on-site only remove the top of strip, not the bottom.

correct ASME/BS EN ISO 6947 code, such as 2G/PC for horizontal/vertical welding. It is suitable for those involved in welding as part of a production engineering department, in fabrication work, design, welder training or welding inspection within a quality control regime.

A FREE guide to ASME IX/BS EN ISO 6947 welding positions is now available from ESAB. As well as showing all the different positions, the guide provides information on the recommended ESAB electrodes when welding mild steel across a range of applications. The simple guide is clearly illustrated to show basic welding positions and the

safety: the project has been realised in order to ensure the operators have easy access to all the various components, and granting at the same time their maximum safety. As an example, the mill is supplied with a special OD bead chopper, and dedicated fences with interlocks all over the mill. This is the second machine in this specific range already built by OTO; the first was made in 2009. Three other heavy duty tube mills in the range 8" to 16", mostly for API tubes, are to be manufactured and delivered before the end of 2013.

round, with a thickness range up to ½". Most of the material to be processed will be from J55 to X100 grade pipe, and the mill is able to reach speeds faster than 200fpm. The customer will use the mill to implement productivity and efficiency in order to satisfy recent important orders. The new concept design of the whole mill (highly automated entry line, special modular rapid tool change, high performance orbital cold saw cut-off) confirms OTO as a leading manufacturer of heavy thickness/ large diameter tube mills. Particular care has been addressed to

mill for a customer in Canada, a leading manufacturer of API tubes. The end product is mainly addressed to green pipe for the energy sector. The green pipe will be manufactured to the tightest specification of the American Petroleum Institute (API). The tube size range is from 3" to 9 5 / 8 "
