Integrated Pigging Valve substitutes Pig Launching System

molchhahn hartmann valves webHartmann pigging valves provide a space- and cost-saving substitution for expensive pig launching systems. In addition to its classic use as shut-off valve, the pigging ball valve functions as pig launcher or receiver valve. The simple, secure, and fast insertion or removal of pigs take place through an interlock that is integrated on the side of the pigging valve and that is locked and secured through a bayonet system.

For an innovative conversion of the ammonia factory Yara was looking for special shut-off valves for extreme conditions. “Hartmann has the reputation being known as the “Mercedes“ among the valve suppliers. For this important conversion we have made the decision for a high quality solution!” says Werner Döring, Head of Projects and Availability, Yara Brunsbüttel GmbH. The 5“ shut-off ball valves from Hartmann Valves are especially designed for the challenging combination of pure oxygen, steam and high temperatures. Jürgen Rommel, ICA Engineering, is very satisfied with Hartmann’s products and service: “We could not accept any risk during this project. With the wrong supplier we would have endangered the conversion, both technically and time-wise”, The conversion to energy efficient production even secured the economic future of the facility.

Spring weather, blue sky, and sunshine made the participation of the HARTMANN RUNNING TEAMs in the 33rd open public run “Celler-Wasa-Lauf” to a full success. On March 8th, 2015, the historic city centre of Celle provided a gorgeous scenery for running on the different mileages from 2.5 to 10 km. All in all our team covered a distance of 280 km, a birthday was celebrated, and even a journey of not less than 978 km to join the run was defied. Moreover, splendid results were achieved: On the 5 km track the best HARTMANN women’s team gained 73rd position which means a ranking among the first half of this competition. On the 10 km track the best HARTMANN men’s team M30 became champion of their age group and, thus, defended the title won the year before. Also remarkable is that 6 children joined the HARTMANN team as budding runners and had a lot of fun.
