Seville, Spain: An unusual construction site in an unusual location
In springlike weather in mid-February 2017, our customer DESABECO, a trained Spanish restoration company, performed a trenchless installation in Seville: 145 continuous meters of a DN 490 / 4.3 GRP tap water liner made by SAERTEX multiCom® GmbH.
The principal for this unusual project was the city of Seville. Not only the project, but also the arena was unusual: the construction project was a reference object in downtown Seville, right on the historic Plaza de España, Parque de María Luisa.
The SAERTEX-LINER® H2O was cured using the compact Power LIGHT UV unit. Before performing the first installation, the DESABECO team received extensive theoretical and practical training on this unit, and was supported on site by technicians from SAERTEX multiCom® GmbH and I.S.T. Innovative Sewer Technologies GmbH while installing and curing the GRP hose liner.
The new compact Power LIGHT UV unit had to be approved for use in the tap water field in advance – not a problem, since of course it had never been used for wastewater.
The construction-site preparation and complete installation of the SAERTEX-LINER® H2O took place in a single day.
The timing as well as the final results were outstanding, and all of the participants were very satisfied.
Successful tests of the Power LIGHT Triple Core performed at SAERTEX multiCom® GmbH in late August/early September 2017
I.S.T. GmbH’s Power LIGHT Triple Core, with an output of 9 x 2,000 watts, is the company’s premier UV light chain thanks to its enormous output and its suitability for pipes with large cross-sections. Its 18,000-watt overall output guarantees perfect curing even for liners with thick walls, and it can be used for liners ranging from DN 1200 to DN 2000.
The Triple Core light source significantly reduces the standard curing time. Thanks to the new booster technology with an overall output of 18,000 watts, it can be adapted for existing systems.
On August 29, as part of the tests performed in the early fall, a SAERTEX-LINER® (Premium) with a nominal width of DN 1500 and a wall thickness of 9 mm was cured at a rate of 70 cm/minute with very good results. This speed is expected to be even higher in practice.
The test used the Power LIGHT KT 300 cable drum; because of the relatively short length of the test section, the cable remained almost completely coiled on the reel, and there were no noteworthy temperature increases in the cable. Long-term tests lasting several hours, performed at our Customer Care Center in Bochum, had already demonstrated this in advance.
The new design proved to be very mechanically stable; the weight of the liner did not pose any problems for the Power LIGHT Triple Core.
On August 30, a SAERTEX-LINER® (Premium) with a nominal width of DN 1200 and a wall thickness of 10 mm was cured at a rate of 75 cm/minute, also with very good results. The surfaces of both GRP liners were perfect, and all of the participants were enthusiastic about the results.
For practical reasons, both tests used an output of 8 x 2,000 watts. If a 9 x 2,000-watt output is used, we can expect a 10 to 15% faster curing rate.
The final results of the above tests will be published shortly on I.S.T. GmbH’s website and Facebook page.
Based on the final results, we can determine the expected service life and speeds. Based on the findings so far, we can already tell they are going to set completely new standards that only recently seemed out of reach – a whole new league of UV technology.
7th Saerbeck pipeline symposium from SAERTEX multiCom® GmbH
The Saerbeck pipeline symposium was held for the seventh time on September 21/22. The symposium has seen very positive development over the years, with its many interesting specialized talks, exhibitors and live presentations, and has become a fixture in the industry.
As in past years, I.S.T. took part in the symposium as well, and was represented by an indoor booth in the hall as well as its nUVision UV technology in the outdoor area.
In lovely weather, I.S.T. presented a fully equipped vehicle that included the latest nUVision equipment and has everything it needs on board to cure UV light-reactive hose liners – for liner lengths up to 1,000 meters!
The evening event on the first day featured the usual relaxed, sociable atmosphere, and all of the participants had a lot of fun.
The event was a great success; we received numerous inquiries from potential customers about the special benefits and unique selling points of the highly innovative nUVision UV technology, and we had many promising conversations
