Combination of welding outlet and flange Nipoflange in pipeline construction A nipoflange is used in pipeline construction just like a welding outlet or a nipple outlet for a 90 ° branch. A Nipoflange is a combination of welding outlet, nipple outlet and flange. Further terms for Nipoflange are Weldoflange or Flangeolet. Two different branch sides On the pipe branch side , a nipo length has the shape of a welding outlet. This means that the branch from the pipe is made with a welded joint. There is a flange on the connection side, ie a flange connection is created. The flange can be designed according to customer requirements (usually according to DIN or ANSI). Nipoflange as a forged fitting A nipoflange (similar to ANSI B 16.9 / MSS-SP 97) is usually made from a forged blank. This means that a Nipoflange is a forged fitting and has no welds.

Swept outlet similar to ANSI B 16.19 / ANSI B 36.10 Swept outlets in pipeline construction A swept outlet is used in pipeline construction just like a welding outlet, a socket welded outlet or a threaded outlet for a 90 ° branch. A swept outlet is an alternative to the T-piece / red. In comparison to the T-piece / Red.Tee, the installation effort for a swept outlet is lower because only one hole has to be drilled into a pipe. The swept outlet can then be welded into this hole. A swept outlet differs from a welding outlet in the type of welding. While a welding outlet is only placed on the run pipe and then welded, a swept outlet is welded directly into the run pipe. Ideal stress distribution Swept outlets were developed in order to achieve the best possible stress distribution for internal pressure and pipe forces. Due to the favorable voltage level, swept outlets are often used in highly stressed pipes in the oil and gas industry.

With the development of CHARM®, Open Grid Europe is providing an efficient leakage control method for natural gas pipeline networks and thus an alternative to the labour intensive practice of conducting on-site inspections of the pipelines with gas detection devices. CHARM® is a highly accurate infrared laser system integrated in a helicopter that is capable of precisely detecting even very low methane concentrations from the air. Even in the case of very complex pipeline topologies, the course of the pipeline can be detected consistently on a large scale during the flight by an automatic, highly precise scanning beam control system (autotracking), thus ensuring a reliable leak tightness inspection of the natural gas pipeline.
