celebrates 10th anniversary of FloForm acquisition and manufacturing in Wales

awson Shanahan, specialists in precision engineering since 1943, celebrates 10 years since the buy-out of


FloForm and manufacturing at its plant in Welshpool, Wales. As a business that had been in decline, the company finally


went into administration in 2009 and 80 jobs were sadly lost. Hertfordshire based Dawson Shanahan, took the


decision to purchase the business and all its assets. They made the strategic decision to retain the Welshpool site re- instating 12 employees. Les Reeves, Joint Managing Director of Dawson Shanahan explains: “On meeting with the FloForm employees, it quickly became apparent that they possessed skills, expertise and enthusiasm that was crucial to our future success. Les adds: “For over 75 years, we have continued to


serve and grow our customers. “We are thrilled to celebrate this milestone and continue


our role in the local community as well as growing our operations over the next ten years and beyond.”

Renold


GE offers to configure level controllers with guided microwave according to customer specifications. Based on its proven standard


level gauge, the German manufacturer is able to adapt the sensors to suit various tank geometries, mounting conditions, or demanding media in no time. Options include angled probes that can be mounted on the side of tanks. EGE employs special materials such as Hastelloy or titanium to manufacture probes for use in aggressive media. EGE also specifically adapts the sensors to dielectric constants and to the temperature ranges of the liquid to be measured to ensure precise results in challenging media and cramped installation conditions.

Tooth chain in the automotive industry A


utomotive supplier Hirschvogel Eisennach relies on Renold tooth chains for a long-lasting and safe solution for the transport of hot steel blanks.


"The interlinking of steelworking machines is a huge challenge," affirms Dennis Reinhardt.


The reasons for this vary: first, the 1,200 ° C hot parts are directly on the transport chain, so that it must be absolutely heat-resistant. The Renold transport chain solves this problem by their involute teeth, so that the chain does not expand despite the heat.


Furthermore, aggravating added that form on the surfaces of the steel parts by heating


oxide layers and this scale then peels off. The tinder is hard and crumbles and settles like salt in the joints. Therefore, additional cleaning discs are used, with which the chain is cleaned with each deflection over the gear, so that the scale falls out and cannot stick to the chain. Dennis Reinhardt comments on these conditions: "That's what a chain has to endure. Here, the statement of functional reliability and long service life due to low wear reaches a completely new dimension. We can only confirm both here."

Replacing direct-on-line starters with ABB variable speed drives has eliminated pipe bursts at Scottish Water's Castle Road pumping station


ABB drives eliminate burst pipes at Scottish Water pumping station

ver £12,000 in maintenance costs is saved per year by eliminating burst pipes through the installation


of ABB drives on two booster pumps. Scottish Water, a utility providing water and


sewerage services across Scotland, suffered nine pipe bursts per year, on average, at its Castle Road pumping station. Each burst was estimated to cost £1,400 through leakage detection, repair materials and labour. The bursts were caused by pumps being started


direct-on-line (DOL). This crude start/stop control created pressure waves causing pipes to fracture and leak. For example, water may be moving at a flow rate of 10 metres per second. If the pump is then switched off, this moving water suddenly hits a dead end, surging back, shocking the network. EDC (Scotland) fitted two 5.5 kilowatt (kW) ABB water


and wastewater drives, one for each of the two booster pumps. The drives provide a soft ramp up and a controlled slow down to maintain supply pressure in the


pipe network. The project was completed in two stages to ensure no disruption to public water supplies. Data loggers were used to gather information on


pressure transients around the Castle Road site. Before the ABB drives were installed, the data revealed that on DOL starting, pressures were peaking at 140 metres head. Following installation of the drives, pressure data was again logged, revealing that starting and stopping the pumps using the VSDs reduced maximum pressures to 83 metres head. Since the installation was commissioned in


November 2016, the utility has had zero pipe bursts. The VSDs have also reduced the energy consumption of the pumps, saving an additional £200 per year. The return on the £5,500 investment in drives was achieved in five- and-a-half months.
